Crystal's Coder Hub👁️ CPT 67911 — Correction Of Lid Retraction
Quick Reference
wRVU: 7.50 (verify CMS RVU26A) | Global Period: 090 (90 days) | Assistant Payable: ❌ Not payable (verify current MPFS indicator) | Bilateral Indicator: 1 — Standard bilateral reduction rules apply; MUE = 2(3) per date of service. Rule: CPT 67911 carries a 90-day global period, the same as major eyelid reconstruction codes. Bilateral indicator 1 means Medicare’s 150% bilateral payment rule applies when both eyelids are corrected in the same session — 100% for the first eyelid, 50% for the second. PC/TC split does not apply (indicator 0 — procedure code only). The MUE of 2(3) reflects that up to two distinct eyelids (e.g., right upper and right lower) may be billed per date of service with appropriate modifier documentation.
📋 Clinical Description
CPT 67911 describes the surgical correction of eyelid retraction, a condition in which one or more eyelid margins are abnormally displaced away from the globe, resulting in excessive scleral or corneal exposure. The procedure physically restores lid position through recession of the retractor mechanism (levator aponeurosis for the upper lid; capsulopalpebral fascia and inferior tarsal muscle for the lower lid), augmentation with a posterior lamellar spacer graft (autologous or nonautologous), or a combination of both techniques. 67911 is the single code for lid retraction correction regardless of whether the upper or lower eyelid is treated and regardless of the specific technique used — it is differentiated from 67909 (reduction of overcorrection of ptosis, where ptosis surgery has produced a retracted lid) and from 67912 (correction of lagophthalmos by lid load implantation, a mechanistically distinct procedure directed at incomplete closure rather than retraction). Laterality and specific eyelid position are captured through modifier assignment, not by code selection.1
Eyelid retraction (H02.531–H02.536) occurs when the normal balance of forces maintaining lid position is disrupted by inflammatory, fibrotic, neurogenic, or iatrogenic processes that tether or shorten the retractor mechanism or the posterior lamella. The most common etiology in adult patients is thyroid eye disease (Graves’ ophthalmopathy), in which lymphocytic infiltration and fibrosis of the orbital fat, extraocular muscles, and levator complex produce chronic contracture and upward displacement of the upper lid margin above the superior limbus; untreated, this leads to corneal exposure, punctate epithelial erosions, and ultimately exposure keratoconjunctivitis (H16.211, H16.212) or frank corneal ulceration. Scarring from prior eyelid or orbital surgery (including overcorrected ptosis repair), radiation fibrosis, and prior cicatricial eyelid disease are the next most common causes. When lid retraction results directly from thyroid eye disease with documented exophthalmos, H06.21–H06.23 (dysthyroid exophthalmos) and E05.00 (thyrotoxicosis with diffuse goiter) should be assigned as additional diagnoses to support medical necessity and accurately represent the clinical picture.2,4
This procedure may be performed in the following clinical contexts:
- Thyroid eye disease (Graves’ ophthalmopathy) with symptomatic lid retraction — The most common indication; surgery is appropriate after orbital and thyroid disease has been clinically stable for at least 6 months and after any required orbital decompression has been completed, so that the lid position achieved is stable. Documentation must include Hertel measurements, lid margin–to-reflex distance (MRD1/MRD2), and evidence of corneal exposure symptoms or signs.7
- Post-surgical lid retraction (iatrogenic) — Occurs after overcorrected ptosis repair, blepharoplasty with excessive skin or fat removal, or prior lid or orbital surgery producing cicatricial shortening of the posterior lamella; etiology code for the prior procedure-related complication supports the medical necessity narrative.
- Cicatricial lid retraction from trauma, chemical injury, or prior irradiation — Fibrotic shortening of the posterior lamella and/or the retractor mechanism secondary to scar formation; requires documentation of the underlying mechanism to select the most specific ICD-10-CM etiology code as an additional diagnosis.
- Corneal exposure with documented lagophthalmos — When the primary structural driver of exposure is lid retraction (rather than pure lagophthalmos), 67911 is the appropriate code; if the surgeon implants a lid load to address the mechanical closure defect rather than repositioning the retractor mechanism, 67912 applies instead; documentation must specify which pathology is being addressed.
- Isolated lower lid retraction following prior lower lid or orbital surgery — Lower lid retraction is separately correctable and separately billable from upper lid retraction on the same eye using distinct E-modifiers; the operative note must specify the distinct surgical site and technique to avoid NCCI bundling issues.3
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Posterior lamellar spacer graft | A graft of autologous tissue (hard palate mucosa, auricular cartilage, or temporalis fascia) or nonautologous material (donor sclera, acellular dermal matrix, or a commercial spacer device) is sutured to the posterior lamella between the superior or inferior tarsus and the recessed retractor edge, physically lengthening the posterior lamella and advancing the lid margin toward the globe. Autologous grafts are harvested during the same operative session and require appropriate documentation of the harvest site. | This is the predominant technique for upper lid retraction and is the most durable approach for moderate to severe thyroid-related retraction (MRD1 > 2 mm above the superior limbus). The operative report must document the type and source of the graft material to support accurate ICD-10-PCS device character assignment (autologous vs. nonautologous). Harvest of autologous material (e.g., hard palate mucosa) is bundled into 67911 and is not separately billable.1,3 |
| Retractor recession without graft | The levator aponeurosis (upper lid) or capsulopalpebral fascia/inferior tarsal muscle (lower lid) is isolated and recessed posteriorly, releasing the tethering force that elevates or depresses the lid margin; sutures may or may not be placed to secure the recessed edge, and a conjunctival suture or nothing is placed in the dead space. This technique is used when lid retraction is mild to moderate or when the surgeon prefers avoiding a donor site. | Because no graft device is placed, the PCS root operation is Release (N) rather than Supplement (U). The distinction matters for inpatient facility coding: assign 08N00ZZ (Release Upper Eyelid Right, Open, No Device) or the appropriate laterality variant rather than a Supplement code. The operative report must explicitly describe the recession technique without graft to support the Release code; if any spacer or suture material is used to hold the recession, revisit the Supplement root operation.5 |
| Combined recession with spacer augmentation (adjunct techniques) | Both retractor recession and graft placement are performed concurrently to achieve the target lid position; Botulinum toxin injection into the levator (CPT 67028 via intravitreal / or specific injection code) may be used in the office as a temporary measure prior to or instead of surgery. Scleral shell fitting for corneal protection during the wait period is not separately reportable under 67911. | A single 67911 captures the complete correction regardless of whether recession alone, graft alone, or both techniques are used — the code is technique-agnostic. Payer prior authorization policies (notably UHC, CIGNA, Humana) require documentation of the specific indication (thyroid disease stability, Hertel measurements, symptoms) and often at least two Hertel readings 6 months apart for Graves’ patients; failure to document these elements is the most common prior authorization denial trigger for this code.7,8 |
Clinical Pearl
The operative report is the make-or-break document for CPT 67911. Three elements must be clearly stated to survive audit: (1) the specific eyelid(s) treated with laterality and upper versus lower designation (to support the correct E-modifier), (2) whether a graft was placed and if so the source material (to support ICD-10-PCS device character selection and to distinguish autologous harvest from nonautologous), and (3) the measured amount of lid recession or target MRD achieved (documenting the functional, not cosmetic, indication). Without documented pre-operative lid margin measurements (MRD1/MRD2) and post-operative comparison, claims for 67911 in the thyroid eye disease population face the highest audit and denial risk, particularly under Medicare Advantage and commercial plans that follow Novitas LCD L35004 criteria.7
✅ Procedure Includes
- Pre-procedure slit-lamp examination and lid margin measurement (MRD1/MRD2 assessment) as part of the operative decision — separately billable E/M only when a significant, separately identifiable service is documented and modifier -25 is appended to the E/M code, not to 67911.
- Local anesthesia with or without monitored anesthesia care (MAC); general anesthesia is occasionally used in pediatric or highly anxious patients and is separately billed by the anesthesiologist under the appropriate 00XXX anesthesia code — the surgeon’s 67911 is not affected.
- All operative steps of the retractor recession, including dissection and identification of the levator aponeurosis or capsulopalpebral fascia, release of fibrotic adhesions, and suture recession of the retractor edge.
- Harvest of autologous graft tissue (hard palate mucosa, auricular cartilage, or fascia) when used as the spacer material — harvest is bundled and not separately reportable as a skin graft or tissue harvest code.
- Placement and fixation of spacer graft (autologous or nonautologous) including all suturing and wound closure.
- Standard postoperative lid and eye care for the 90-day global period, including visits for suture removal, wound assessment, and assessment of lid position outcome.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship to 67911 |
|---|---|---|
| 67909 | Reduction of overcorrection of ptosis | Mutually exclusive for the same eyelid in the same session. 67909 is used when a previously performed ptosis repair has produced an overcorrected (retracted) lid and the surgeon is revising that prior repair — the etiology is iatrogenic overcorrection of ptosis. If the documentation supports overcorrection of a prior ptosis repair as the specific cause, 67909 is the correct code, not 67911. When the retraction results from thyroid disease or another non-iatrogenic cause, 67911 applies. Do not report both for the same eyelid in the same encounter.1,3 |
| 67912 | Correction of lagophthalmos, with implantation of upper eyelid lid load (e.g., gold weight) | Mechanistically distinct from 67911. 67912 addresses the functional inability to completely close the eyelid by implanting a gravity-dependent lid weight; 67911 addresses the structural displacement of the lid margin away from the globe by repositioning the retractor mechanism. When both procedures are performed on the same eyelid at the same session (a rare but documented scenario), they may be reported together with modifier -51 on the lower-valued code — however, NCCI edit review and payer policy must be confirmed before billing both, and the operative note must clearly describe two distinct, separately necessary interventions.3 |
| 67904 | Repair of blepharoptosis; (tarso)levator resection or advancement, external approach | 67904 targets a ptotic (low) lid; 67911 targets a retracted (high) lid. They address opposite positional abnormalities and are not reportable for the same eyelid at the same session. When both are performed for separate eyelids in the same session (e.g., right upper ptosis and left upper retraction), use modifier -51 on the lower-valued code and document each eyelid’s independent pathology. NCCI edits do not bundle them for contralateral sites, but documentation must clearly establish each independent surgical indication.3 |
| 67950 | Canthoplasty | Canthoplasty may be separately reportable with 67911 when it addresses a distinct anatomic site (e.g., lateral canthal laxity contributing independently to lower lid malposition) and is documented as a separate, medically necessary procedure. If the canthoplasty is integral to the lid retraction repair (e.g., as a stabilizing maneuver), it is bundled into 67911 and not separately billable. Use modifier -59 on 67950 only when the documentation unambiguously establishes a distinct surgical indication and site for the canthal repair.3 |
| E/M codes (99202–99215 / 92002–92014) | Office visit or ophthalmologic examination, any level | Separately reportable on the same date of service only when modifier -25 is appended to the E/M code — not to 67911 — and the medical record documents a significant, separately identifiable evaluation and management service beyond the standard pre-procedure assessment bundled into the surgical global package. |
Bundling Alert — Global Period Is 090 (90 Days)
CPT 67911 carries a 90-day global surgical package. All routine evaluation and management visits related to post-operative care of the lid retraction correction from the day of surgery through the 90th postoperative day are bundled into 67911’s payment and must not be billed separately to Medicare or most commercial payers. The most common audit finding for this code family is unbundled 92012 or 99213 visits at 1-week and 4-week post-op appointments that are documented as lid position checks — these are clearly bundled. To separately bill an E/M within the 90-day global window, the visit must address an unrelated condition; append modifier -24 to the E/M code (not 67911) and document the unrelated nature explicitly in the medical record. Failure to track the 90-day window operationally (using the procedure date as the start) is the most common compliance exposure for practices billing this code at high volume.2,3

Bilateral Billing Rules
CPT 67911 has a bilateral indicator of 1, meaning standard CMS bilateral payment rules apply. When lid retraction correction is performed on both the right and left upper eyelids (or any combination of upper and lower lids across both eyes) in the same operative session, the preferred billing format depends on the MAC: most MACs accept either a single line with modifier -50 (billing the code once with -50 appended) or two separate lines with modifiers -RT and -LT (or E-modifiers). Under Medicare’s bilateral reduction policy, bilateral payment equals 150% of the single-procedure fee — 100% for the first procedure and 50% for the second. When using separate lines with -RT/-LT or E-modifiers, append -51 to the second line to reflect the multiple procedure reduction; if using -50 on a single line, no -51 is needed. Note that MUE of 2(3) confirms CMS anticipates up to two separate eyelid units per date of service. Always verify the current MAC’s preferred billing format (single line vs. dual line) before claiming, as this preference varies by jurisdiction.2
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -E1 | Upper Left Eyelid | Apply to 67911 when the correction is performed on the upper left eyelid. E-modifiers provide greater specificity than -RT/-LT alone and are the standard for Medicare eyelid procedures; always specify -E1–-E4 for ophthalmology claims when the procedure is eyelid-specific. |
| -E2 | Lower Left Eyelid | Apply when lower left eyelid retraction is corrected. Note that lower lid retraction correction (-E2 or -E4) on the same date as upper lid correction (-E1 or -E3) on the same eye requires documentation of independent medical necessity for each eyelid. |
| -E3 | Upper Right Eyelid | Apply when upper right eyelid retraction is corrected. For thyroid eye disease, upper lid retraction is the most common site and -E3 is frequently the primary modifier. |
| -E4 | Lower Right Eyelid | Apply when lower right eyelid retraction is corrected. Lower lid retraction repair is less common but fully separately reportable using -E4 with separate operative documentation. |
| -RT | Right Side | Alternative to -E3/-E4 when E-modifiers are not required by the payer; -RT designates the right eye globally. E-modifiers are preferred over -RT/-LT for eyelid-specific procedures as they provide both laterality and upper/lower specificity. |
| -LT | Left Side | Alternative to -E1/-E2; use when the payer does not accept E-modifiers. -LT alone does not distinguish upper from lower lid and may result in a request for additional documentation. |
| -50 | Bilateral Procedure | Apply as a single-line billing format when lid retraction correction is performed bilaterally in the same session. Confirm MAC preference for -50 single-line vs. dual-line with -RT/-LT or E-modifiers before billing; applying -50 with E-modifiers simultaneously on the same claim line creates a conflict and should be avoided. |
| -25 | Significant, Separately Identifiable E/M | Applied to the E/M code — not 67911 — when an office or ophthalmologic exam is performed on the same date of service as the procedure and constitutes a separately identifiable, medically necessary evaluation beyond the routine pre-procedure assessment. The documentation must include a distinct history, examination, and medical decision-making for a service that would stand alone if the procedure were not performed. |
| -24 | Unrelated E/M During Postoperative Period | Applied to the E/M code when the patient presents within the 90-day global window for a condition entirely unrelated to lid retraction surgery; the medical record must explicitly document the unrelated nature and the distinct clinical reason for the visit. |
| -51 | Multiple Procedures | Apply to 67911 (on the lower-valued code line) when it is reported alongside other surgical procedures in the same operative session — for example, when lid retraction repair and canthoplasty (67950) are reported together, -51 goes on 67950 as the lesser-valued code. |
| -59 | Distinct Procedural Service | Use when payers incorrectly bundle 67911 with another procedure that was performed at a distinct anatomic site, at a separate session, or for an independent clinical indication not addressed by the primary procedure code. |
| -52 | Reduced Services | Apply when the procedure is initiated but not completed as planned (e.g., patient discomfort or unexpected anatomic finding necessitating a limited correction); document the specific reason for reduction in the operative report. |
| -53 | Discontinued Procedure | Apply when the procedure is halted after anesthesia has been administered due to a patient safety concern or complication preventing completion; thorough documentation of the reason is mandatory. |
| -58 | Staged or Related Procedure | Apply when a planned staged second-session lid retraction correction is performed during the 90-day global window of the first procedure — for example, when the surgeon initially addresses one eye and documents a planned return for the contralateral eye. Document the staged plan in the original operative note. |
| -78 | Unplanned Return to OR | Apply when the patient returns to the operating room during the 90-day global period for an unplanned complication of the original lid retraction repair (e.g., wound dehiscence, graft failure, hematoma requiring drainage). |
| -79 | Unrelated Procedure During Postoperative Period | Apply when a procedure unrelated to lid retraction correction is performed during the 90-day global window (e.g., cataract surgery on the same patient; the lid retraction repair and cataract extraction are unrelated procedures). |
🩺 Common ICD-10-CM Pairings
Primary Diagnosis Group — Eyelid Retraction
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| H02.531 | Eyelid retraction, right upper eyelid | ❌ No | Most common primary diagnosis for 67911 in thyroid eye disease; right upper lid retraction is the most frequent clinical presentation. Query provider for laterality and upper vs. lower designation when documentation is ambiguous — H02.531 requires all three axes: laterality (right), position (upper), and specificity (not merely “eyelid retraction, right eye”).4 |
| H02.532 | Eyelid retraction, right lower eyelid | ❌ No | Use when correction is performed on the right lower eyelid. Lower lid retraction may occur independently or in combination with upper lid retraction in thyroid eye disease; if both upper and lower lids on the same eye are corrected, both H02.531 and H02.532 may be reported as co-diagnoses to reflect the full clinical picture. |
| H02.534 | Eyelid retraction, left upper eyelid | ❌ No | Left upper lid retraction; frequently bilateral in thyroid eye disease, so H02.531 and H02.534 may both appear on the same claim when bilateral correction is performed. |
| H02.535 | Eyelid retraction, left lower eyelid | ❌ No | Use for left lower lid retraction correction. When combined upper and lower retraction is treated on the same eye, assign both the upper and lower codes for that eye to accurately represent the full scope of the clinical condition addressed. |
| H02.533 | Eyelid retraction, right eye, unspecified eyelid | ❌ No | Use only when the operative note confirms treatment of the right eye but fails to specify upper vs. lower; query the provider before defaulting to this code — “unspecified eyelid” is a documentation gap, not a valid coding choice when the operative report clearly identifies the eyelid. |
| H02.536 | Eyelid retraction, left eye, unspecified eyelid | ❌ No | Same guidance as H02.533; avoid if upper vs. lower is determinable from the operative note or modifier selection. |
| H02.539 | Eyelid retraction, unspecified eye, unspecified lid | ❌ No | Use only as a last resort when neither laterality nor eyelid position can be determined from available documentation; this is an audit red flag when paired with 67911 because the operative report should always specify which eyelid was treated. Query the surgeon before assigning this code.4 |
Secondary Diagnosis Group — Thyroid Eye Disease / Dysthyroid Exophthalmos
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| H06.21 | Dysthyroid exophthalmos, right eye | ❌ No | Assign as an additional diagnosis when lid retraction is directly attributable to thyroid eye disease (Graves’ ophthalmopathy) with documented exophthalmos of the right eye; this code significantly strengthens the medical necessity narrative and is required by several payer prior authorization policies. Do not assign without documented exophthalmos measurements (Hertel exophthalmometry values).7 |
| H06.22 | Dysthyroid exophthalmos, left eye | ❌ No | Same guidance as H06.21 for the left eye. Bilateral exophthalmos in thyroid eye disease is common; assign both H06.21 and H06.22 if bilateral exophthalmos is documented, even if only one eyelid is being surgically corrected at this session. |
| H06.23 | Dysthyroid exophthalmos, bilateral | ❌ No | Use when bilateral exophthalmos is documented as a single bilateral entity; some providers document “bilateral proptosis” without distinguishing right vs. left measurements, in which case H06.23 is appropriate. If separate Hertel measurements are given for each eye, prefer H06.21 + H06.22 for greater specificity. |
Etiology / Complication Codes
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| E05.00 | Thyrotoxicosis with diffuse goiter without thyrotoxic crisis or storm | ❌ No — verify CMS-HCC V28 | Report as an additional diagnosis when the underlying cause of lid retraction is Graves’ disease/hyperthyroidism documented by the treating provider; establishes the systemic disease context for the ocular complication. This code does not replace H06.21–H06.23 — both the ocular manifestation and the underlying thyroid disease should be reported. Verify HCC status against current CMS-HCC V28 model files if used in a risk-adjustment context.4 |
| H16.211 | Exposure keratoconjunctivitis, right eye | ❌ No | Report when corneal exposure keratoconjunctivitis is documented as a complication or direct consequence of lid retraction and represents an independent reason for surgical intervention; this code supports medical necessity when payers challenge the reconstructive classification of 67911. Requires documented slit-lamp findings (punctate epithelial erosions, corneal staining) in the medical record.4,6 |
| H16.212 | Exposure keratoconjunctivitis, left eye | ❌ No | Same as H16.211 for the left eye. When bilateral corneal exposure is documented, both H16.211 and H16.212 may be assigned if the clinical record supports bilateral findings. |
Coding Specificity Reminder
ICD-10-CM codes for eyelid retraction require specificity across three axes: (1) laterality (right vs. left), (2) eyelid position (upper vs. lower), and (3) specificity (the fully specified 6-character code vs. the non-billable parent H02.53). The 6-character codes H02.531–H02.536 are the billable eyelid retraction codes; H02.53 is a category header and must never appear on a claim. Coders should also confirm from the operative note and/or modifier selection which specific eyelid is being documented — if modifier -E3 is billed (upper right), the diagnosis should be H02.531, not H02.533 or H02.539. A mismatch between the E-modifier and the ICD-10-CM specificity level is one of the most common claim editing triggers for this procedure. When documentation is ambiguous, the query-first standard applies before a less-specific code is assigned.4
🏥 MS-DRG Considerations (Inpatient)
Inpatient Coding Reminder
CPT 67911 is performed exclusively in the outpatient or ASC setting. Inpatient admission for isolated lid retraction correction is not clinically expected, and no routine MS-DRG assignment would be driven by this procedure alone. However, if a patient is admitted inpatient for an unrelated diagnosis (e.g., cardiac surgery, systemic thyroid crisis) and lid retraction is coded as a secondary diagnosis, the H02.53x codes map under MS-DRG v42.0 to DRG 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent), DRG 125 (Other Disorders of the Eye with CC), or DRG 126 (Other Disorders of the Eye without CC/MCC), depending on the CC/MCC profile of the principal and additional diagnoses. In that inpatient scenario, the ICD-10-PCS equivalent code (see below) would be assigned for the procedure rather than the CPT code, and it is unlikely to shift DRG grouping unless it constitutes the principal procedure driving admission.2,5
🔧 ICD-10-PCS Equivalents (Inpatient Facility Coding)
Note
Inpatient coding for lid retraction correction is encountered only when the patient is admitted for an unrelated condition and the procedure is performed concurrently or when a rare complication necessitates inpatient admission. The PCS root operation depends critically on technique: if a spacer graft is placed, Supplement (U) is the correct root operation; if retractor recession alone is performed without any graft or device, Release (N) is used. These two root operations are not interchangeable — the operative report must be reviewed for the presence or absence of graft material before assigning the PCS code. PCS codes will not typically shift DRG grouping when the admission is driven by a non-ocular principal diagnosis, but they must still be assigned accurately for complete and compliant inpatient facility coding.5
| PCS Code | Full Description | Applicable Technique |
|---|---|---|
08U007Z | Supplement, Upper Eyelid, Right, Open Approach, Autologous Tissue Substitute, No Qualifier | Spacer graft using autologous material (hard palate mucosa, auricular cartilage, temporalis fascia) — upper right eyelid |
08U10KZ | Supplement, Upper Eyelid, Left, Open Approach, Nonautologous Tissue Substitute, No Qualifier | Spacer graft using nonautologous material (donor sclera, acellular dermal matrix, commercial spacer) — upper left eyelid |
08U207Z | Supplement, Lower Eyelid, Right, Open Approach, Autologous Tissue Substitute, No Qualifier | Spacer graft using autologous material — lower right eyelid retraction correction |
08U30KZ | Supplement, Lower Eyelid, Left, Open Approach, Nonautologous Tissue Substitute, No Qualifier | Spacer graft using nonautologous material — lower left eyelid retraction correction |
PCS Character Analysis — 08U007Z
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical — the foundational section for all operative procedures; applies to all surgical interventions on body parts in the inpatient setting. |
| 2 | Body System | 8 | Eye — encompasses the eyeball, eyelids, lacrimal apparatus, and ocular musculature; the eyelid body parts (upper and lower, right and left) are all housed within this body system. |
| 3 | Root Operation | U | Supplement — defined in ICD-10-PCS as “putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.” This root operation is correct when a spacer graft (autologous or nonautologous) is placed to physically lengthen the posterior lamella and reinforce the lid position; it is NOT correct when only retractor recession without any device is performed. |
| 4 | Body Part | 0 | Upper Eyelid, Right — one of four eyelid body parts in the Eye body system (0 = Upper Right, 1 = Upper Left, 2 = Lower Right, 3 = Lower Left); selection must match the specific eyelid addressed in the operative note. |
| 5 | Approach | 0 | Open — the standard surgical approach for lid retraction correction, involving a skin or conjunctival incision with direct visualization of the retractor mechanism; a conjunctival (posterior) approach is still classified as Open in PCS because it involves cutting through mucosa to access the levator/retractor complex directly. |
| 6 | Device | 7 | Autologous Tissue Substitute — use character 7 when the graft is harvested from the patient (hard palate mucosa, auricular cartilage, fascia lata, temporalis fascia); use K (Nonautologous Tissue Substitute) for donor sclera or acellular dermal matrix; use J (Synthetic Substitute) for commercial synthetic spacer materials. The device character must match what is documented in the operative report as the actual graft material used. |
| 7 | Qualifier | Z | No Qualifier — the standard qualifier value for this procedure; no additional specification is needed beyond the body part, approach, and device characters already assigned. |

08U0_Z,08U1_Z,08U2_Z,08U3_Zwith the appropriate device character — when the operative note documents placement of any graft, spacer, or augmentation material to reinforce or lengthen the posterior lamella. This is the most common scenario for lid retraction correction and applies to both autologous (character 7), synthetic (character J), and nonautologous (character K) materials.- Use Release (N) — codes
08N00ZZ,08N10ZZ,08N20ZZ,08N30ZZ(Open approach, no device, no qualifier) — when the operative note documents levator recession or retractor recession only, with no graft or device placed; the PCS definition of Release (“freeing a body part from an abnormal physical constraint by cutting or by use of force”) accurately describes the recession of fibrotic retractor tissue without augmentation.- When bilateral eyelids are corrected in the same operative session, assign separate PCS code lines for each eyelid treated — ICD-10-PCS has no bilateral modifier equivalent; each body part character (0, 1, 2, 3) must appear on its own code line with the applicable root operation, approach, device, and qualifier characters.
📝 Coding Examples
Example 1 — ASC: Right Upper Lid Retraction, Thyroid Eye Disease, Spacer Graft
Clinical Scenario: A 54-year-old woman with a 3-year history of Graves’ disease presents with right upper lid retraction measuring MRD1 of +6 mm (normal ≤ 4.5 mm) and right-sided proptosis (Hertel 23 mm base 106, confirmed on two measurements 8 months apart). She reports constant ocular irritation, tearing, and inability to fully close the right eye at night. Thyroid function has been euthyroid for 14 months. The surgeon performs correction of the right upper lid retraction via posterior lamellar hard palate mucosal spacer graft under MAC anesthesia in an ASC setting. The operative report documents: “The right upper eyelid was everted. The levator aponeurosis was identified and recessed 6 mm. A hard palate mucosal graft measuring 8 × 12 mm was harvested from the right hard palate and sutured to the superior tarsus with 6-0 Vicryl. Post-operatively, MRD1 measures 4 mm.” A separate preoperative E/M was performed at a prior visit and is not billed on the date of service.
| Field | Code | Rationale |
|---|---|---|
| CPT | 67911--E3 | Correction of lid retraction, right upper eyelid; modifier E3 specifies upper right eyelid and is required by Medicare and most payers for eyelid procedure localization; the hard palate harvest is bundled and not separately billable. |
| PDx | H02.531 | Eyelid retraction, right upper eyelid — most specific code with laterality (right) and eyelid position (upper) confirmed by operative documentation; matches the E3 modifier. |
| SDx | H06.21 | Dysthyroid exophthalmos, right eye — documented by Hertel measurement and confirmed thyroid disease history; supports medical necessity and prior authorization compliance. |
| SDx | E05.00 | Thyrotoxicosis with diffuse goiter without thyrotoxic crisis — underlying systemic cause of the orbital/lid pathology; reported as additional diagnosis per coding guidelines when thyroid disease is documented by the treating provider. |
Note
No modifier -25 is needed here because the E/M was performed at a prior encounter, not on the date of surgery. If a separate ophthalmologic examination had been performed on the same date to evaluate a distinct, unrelated ocular problem (e.g., new-onset floaters), -25 would be appended to that E/M code — not to 67911 — and the E/M documentation would need to stand independently of the pre-procedure assessment for lid retraction.
Example 2 — ASC: Bilateral Upper Lid Retraction Correction, Thyroid Eye Disease, Same Session
Clinical Scenario: A 61-year-old male with bilateral Graves’ ophthalmopathy presents for correction of bilateral upper lid retraction. Pre-operative measurements show MRD1 of +5.5 mm right upper lid and +5.0 mm left upper lid. Bilateral proptosis (Hertel 22 mm right, 21 mm left) is documented at two time points over the past year. The patient has been euthyroid for 18 months and has completed orbital decompression 9 months prior. The surgeon performs bilateral upper lid retraction correction via donor scleral spacer graft (nonautologous) under general anesthesia; the procedure is documented as two distinct surgical sites — right upper lid, then left upper lid — with separate graft measurements and suture placement documented for each eyelid. The anesthesiologist bills separately. No separate E/M is performed on the day of surgery.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 67911--E3 | Correction of lid retraction, right upper eyelid — primary procedure, full fee (100%). |
| CPT 2 | 67911--E1--51 | Correction of lid retraction, left upper eyelid — secondary procedure, subject to multiple procedure reduction (50% per bilateral indicator 1 rules); modifier -51 on the second line; -E1 specifies left upper eyelid. |
| PDx | H02.531 | Eyelid retraction, right upper eyelid — primary diagnosis corresponding to the first surgical site; most specific available code. |
| SDx | H02.534 | Eyelid retraction, left upper eyelid — secondary diagnosis for the contralateral lid; both H02.531 and H02.534 are reported to reflect the bilateral nature of the underlying condition. |
| SDx | H06.23 | Dysthyroid exophthalmos, bilateral — bilateral exophthalmos documented by Hertel measurements on both eyes; supports medical necessity for bilateral correction. |
| SDx | E05.00 | Thyrotoxicosis with diffuse goiter without thyrotoxic crisis — systemic etiology; reported as additional diagnosis. |
Warning
Modifier -51 belongs on the second procedure code line (67911-E1-51), not on the first. Placing -51 on the first (higher-valued) line inverts the reduction and results in underpayment for the primary procedure. Additionally, modifier -50 should not be combined with E1/E3 on the same line — if the MAC requires single-line bilateral billing with -50, use 67911-50 without E-modifiers and submit the laterality documentation in the record. Confirm MAC format preference before submitting bilateral eyelid claims to avoid systematic rejections.
Example 3 — Outpatient Hospital: Post-Ptosis-Repair Overcorrection vs. De Novo Retraction — Global Period and Query Scenario
Clinical Scenario: A 48-year-old woman returns 4 months after right upper eyelid ptosis repair (67904) with a complaint that her right eye “looks too open.” The operative note from the original surgery is in the chart. The current visit is for evaluation; the surgeon documents “right upper lid overcorrection post-levator resection, MRD1 now +5.5 mm, patient symptomatic with dry eye and photophobia.” The surgeon plans correction and schedules a return to the ASC. A pre-operative examination is performed today. At the subsequent ASC visit 2 weeks later, the correction is performed. The coder must determine whether to use 67909 (reduction of overcorrection of ptosis) or 67911 (correction of lid retraction) — and must also evaluate whether the today’s E/M visit falls within the 90-day global period of the original ptosis repair.
| Field | Code | Rationale |
|---|---|---|
| E/M (today’s visit) | 92012--24 | Ophthalmologic examination, established patient, intermediate; modifier -24 is required because this visit falls within the 90-day global period of the original 67904 ptosis repair; documentation must explicitly state the visit is for evaluation of overcorrection, a complication separate from the routine post-op care of the ptosis repair. |
| CPT (ASC, 2 weeks later) | 67909--E3 | Reduction of overcorrection of ptosis, right upper eyelid; 67909 — NOT 67911 — is correct here because the operative note documents an iatrogenic retraction resulting specifically from a prior ptosis repair; the etiology (overcorrected ptosis) drives code selection, not the anatomical appearance (retracted lid). |
| PDx (ASC visit) | H02.531 | Eyelid retraction, right upper eyelid — most specific diagnosis; the retraction is the condition being surgically treated even though 67909 captures the procedure. |
Global period reminder
The original 67904 ptosis repair carries a 90-day global period. Any visit within those 90 days that is related to the ptosis repair — including evaluation and management of the resulting overcorrection — is bundled into 67904’s payment and requires modifier -24 if billed separately (because the overcorrection is a complication/sequela of that surgery, making it “related”). The second surgical procedure (67909) performed 4 months after the original repair would fall outside the 90-day global period and does NOT require modifier -78 or -58 — it is a new surgical event. However, if the repeat correction were performed within 90 days of the original ptosis repair and was for the same clinical problem (the overcorrection), modifier -78 (unplanned return to OR for complication) would be required instead. Tracking the global period start date from the original operative date and distinguishing related from unrelated return visits is essential to correct claim submission and compliance for this code family.
⚠️ Common Coding Pitfalls
-
Assigning 67909 when 67911 is correct (or vice versa) without querying the operative note: The distinction between these two codes depends entirely on documented etiology, not on the physical appearance of the retracted lid. A lid that sits above the limbus looks identical whether the cause is thyroid disease (67911) or an overcorrected prior ptosis repair (67909). Coders must review the operative note for a documented reference to prior ptosis surgery as the cause; when the note is ambiguous or silent on etiology, a query to the surgeon is mandatory before code assignment. Defaulting to 67911 without reading the operative note is the most common audit exposure for this code family.
-
Applying modifier -25 to 67911 instead of the E/M code: Modifier -25 always goes on the evaluation and management code (92012, 92014, 99213, 99214, etc.) — never on the procedure code 67911. Placing -25 on the surgical code is a claim-editing error that will result in rejection or denial by most clearinghouses. The operative note must also contain a separately documented E/M service that stands on its own clinical merits, not simply the standard pre-procedure assessment for the surgery.
-
Using H02.539 (unspecified eye, unspecified lid) when laterality and lid position are clearly documented: The operative report for [[67911]] always identifies the specific eyelid treated (if it does not, that is itself a documentation deficiency). The modifier selection (-E1, -E2, -E3, -E4) directly signals the specific eyelid, and the ICD-10-CM code must align — a claim with modifier -E3 paired with H02.539 creates a laterality conflict that triggers editing and is a red flag on audit. Always match the ICD-10-CM specificity to the modifier level; query the provider for any missing laterality or upper/lower designation before defaulting to an unspecified code.
-
Billing same-day blepharoplasty and 67911 for the same eyelid without adequate documentation of distinct indications: Blepharoplasty (e.g., 15820–15823) may be separately reportable with 67911 when a medically necessary upper lid skin excision is documented independently from the lid retraction repair, but NCCI policy and the CMS Chapter 8 NCCI manual specifically address this combination. The NCCI policy states that procedures performed on the ipsilateral eye should not be reported separately with 67911 without clear documentation of distinct surgical sites and separate indications; use modifier -59 only when the documentation fully supports two independent procedures with independent medical necessity, and confirm the NCCI edit status for the specific code pair before billing.
-
Not tracking the 90-day global period operationally and billing routine post-op visits separately: The 90-day global period for 67911 begins on the date of surgery and includes all related evaluation visits through day 90. Practices that do not flag surgical dates in their scheduling and billing systems routinely generate unbundled E/M claims for lid position check visits at one week, four weeks, and eight weeks post-op — all of which are bundled into the global payment. This is one of the highest-frequency findings in ophthalmology practice compliance reviews and results in recoupment of overpayments when identified by MACs or RAC auditors.
-
Failing to document the ICD-10-CM etiology code (E05.00, H06.21–H06.23) for Graves’-related lid retraction: Many practices code only H02.531–H02.536 and omit the thyroid disease and exophthalmos codes. While this does not create an NCCI or billing error per se, it weakens the medical necessity narrative, increases prior authorization denial risk for payers that require documentation of thyroid disease stability and exophthalmos measurements, and underrepresents the clinical complexity of the encounter. Assign H06.21–H06.23 and E05.00 as additional diagnoses whenever the operative note and chart document Graves’ disease as the underlying etiology.
