Crystal's Coder Hub👁️ CPT 92201 — Ophthalmoscopy, Extended; With Retinal Drawing and Scleral Depression of Peripheral Retinal Disease, With Interpretation and Report, Unilateral or Bilateral
“Ophthalmoscopy, extended; with retinal drawing and scleral depression of peripheral retinal disease (eg, for retinal tear, retinal detachment, retinal tumor) with interpretation and report, unilateral or bilateral”
Quick Reference
wRVU: 0.53 | Global Period: 000 | Assistant Payable: No | Bilateral Indicator: 2
Rule: The bilateral indicator of 2 means payment is the same whether one or both eyes are examined — the fee schedule rate already accounts for bilateral performance, and modifier -50, -RT, and -LT are not appended to this code. The global period of 000 means only the day of the procedure is bundled; there is no pre-op or post-op period included in the payment. CPT 92201 replaced the retired codes 92225 and 92226 effective January 1, 2018; those legacy codes are no longer billable and must not be used. Unlike the old initial/subsequent structure, 92201 carries no “initial vs. subsequent” distinction — it is reported every time the service is appropriately performed and documented.
📋 Clinical Description
CPT 92201 describes an extended ophthalmoscopy of the peripheral retina performed using an indirect ophthalmoscope (typically binocular indirect ophthalmoscopy, or BIO) with scleral depression — a technique in which a thimble-like instrument is pressed against the outer eye wall to rotate and indent the peripheral retina into view — paired with a detailed, labeled retinal drawing and a written interpretation and report. This is a fundamentally different service from the routine funduscopic exam bundled into a standard eye visit (CPT 92002–92014): routine ophthalmoscopy is a brief internal survey, while 92201 is a meticulous, time-intensive evaluation of the peripheral retinal periphery specifically targeted at known or suspected pathology such as retinal tears, lattice degeneration, peripheral tumors, or the leading edge of a retinal detachment. The mandatory scleral depression component is what clinically and documentarily distinguishes 92201 from a standard dilated fundus exam — without documented scleral depression, the claim for 92201 is not supportable.
The retinal drawing produced during the 92201 encounter is not a simple diagram — it must be a clearly labeled, anatomically accurate schematic that identifies the specific pathology found, its clock-hour location, its relationship to the ora serrata and equator, and any features such as flap configuration of a tear or pigment demarcation of a detachment.4 The drawing serves both as the clinical record of findings and as the primary audit documentation justifying the extended ophthalmoscopy service. A narrative note alone, without a qualifying drawing, does not meet CPT 92201 documentation requirements. The physician must personally perform the examination and scleral depression, or be directly present and responsible for an appropriately supervised examination, and must author the written interpretation and report.2
This procedure may be performed in the following clinical contexts:
- Acute-onset symptomatic posterior vitreous detachment (PVD) with photopsia/floaters — A patient presents with new-onset flashes and floaters; dilated BIO with scleral depression of the entire 360° periphery is performed to identify any associated retinal tears before they progress to detachment. The retinal drawing documents the presence or absence of horseshoe tears, lattice degeneration, and vitreoretinal traction.3
- Known retinal detachment — extent mapping — In a patient with a rhegmatogenous retinal detachment, 92201 is used to map the full extent of the detachment, identify all retinal breaks (primary and satellite), and document the demarcation line and subretinal fluid extent. This drawing directly guides surgical planning for scleral buckle or vitrectomy.1
- Surveillance of retinal tumors (e.g., choroidal nevus vs. melanoma) — A patient with a documented peripheral choroidal lesion undergoes serial extended ophthalmoscopy to track changes in size, pigmentation, and associated subretinal fluid. The detailed drawing allows comparison between visits to detect subtle growth or malignant transformation.4
- Lattice degeneration with or without atrophic holes — Patients with high myopia or family history of retinal detachment often have lattice degeneration; 92201 with scleral depression documents the extent, location, and any associated full-thickness holes, supporting medical necessity for prophylactic laser treatment.2
- Post-trauma peripheral retinal evaluation — After blunt or penetrating ocular trauma, extended ophthalmoscopy with scleral depression is performed to evaluate for dialysis (disinsertion at the ora serrata), peripheral tears, or contusion-associated pathology that would be invisible without peripheral indentation.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Binocular Indirect Ophthalmoscopy (BIO) with Scleral Depression | The physician wears a head-mounted binocular indirect ophthalmoscope that projects a bright coaxial light beam into the dilated eye. A hand-held condensing lens (typically 20D or 28D) focuses the diverging rays to create an aerial image of the fundus. A scleral depressor — a small, thimble-shaped instrument — is simultaneously applied to the eyelid or conjunctiva overlying the peripheral sclera to indent and rotate the peripheral retina into the visualized field, allowing examination to the ora serrata. | BIO provides a wide field of view (up to 60°–65° with a 20D lens) and stereoscopic depth perception, making it the gold standard for peripheral retinal examination. Pupillary dilation with pharmacologic mydriasis (typically 1% tropicamide ± 2.5% phenylephrine) is required. The retinal drawing is customarily made on a standardized retinal diagram during or immediately after the exam. Documentation must specifically note that scleral depression was performed — this is the element that clinically and from a payer perspective distinguishes 92201 from a routine dilated fundus exam.13 |
| Extended Ophthalmoscopy with Fundus Contact Lens or 3-Mirror Lens | A fundus contact lens (e.g., Goldmann 3-mirror, Volk Area Centralis) is placed on the anesthetized cornea with coupling gel, allowing the slit-lamp biomicroscope to image the peripheral retina with high magnification and stereopsis. The 3-mirror lens includes a peripheral mirror angled to view up to the ora serrata. | While contact lens biomicroscopy offers superior image detail compared to BIO, it is performed with the patient at the slit lamp rather than supine, and the field of view is narrower, requiring quadrant-by-quadrant examination. For CPT 92201, the documentation must still reflect scleral depression or an equivalent technique that enables peripheral retinal visualization beyond what routine ophthalmoscopy provides. Some payer LCDs explicitly list acceptable techniques; verify with your MAC.2 |
| Intraoperative Extended Ophthalmoscopy | BIO with scleral depression is sometimes performed in the operating room prior to or during a surgical procedure (e.g., before cryopexy or laser retinopexy for a detected peripheral tear). In this setting, the diagnostic ophthalmoscopy service may be bundled into the surgical procedure’s global package. | If CPT 92201 is performed in the office prior to a scheduled surgical procedure and the findings drive the decision for surgery, it is separately billable. If performed on the same day as surgery, verify whether the service is integral to the operative decision-making (and thus bundled) or a genuinely distinct diagnostic service. CMS global surgery bundling rules apply, and a modifier (-57 on the E/M, or -25 if applicable) may be needed on same-day claims.4 |
Clinical Pearl
The retinal drawing is not optional — it is a required element of CPT 92201, and its absence is the #1 audit finding and denial reason for this code.3 The drawing must identify the pathology by clock-hour position, label anatomical landmarks (ora serrata, equator, optic disc, macula), and be signed or initialed by the examining physician. A narrative description of the peripheral findings — no matter how detailed — does not substitute for a qualifying drawing. Pre-printed standardized retinal diagram forms or EHR-integrated drawing tools are both acceptable, but the output must be a labeled, individualized schematic of the patient’s actual findings, not a generic or stock image.2
✅ Procedure Includes
- Binocular indirect ophthalmoscopy (BIO) of the peripheral fundus — The complete indirect ophthalmoscopic examination of the peripheral retina, including visualization to the ora serrata with the indirect lens and head-mounted illuminator, is bundled into the single unit of 92201.1
- Scleral depression of the peripheral retina — This is a mandatory, non-separately-billable component of 92201. Application of a scleral depressor to indent the peripheral sclera and rotate peripheral retinal structures into view is what makes the exam “extended” and defines the code.3
- Mydriasis/pupil dilation (pharmacologic) — Administration of topical mydriatic agents to achieve adequate dilation for peripheral retinal visualization is considered integral to the procedure and not separately reportable.
- Retinal drawing — The labeled anatomical diagram of peripheral retinal findings created during or immediately following the examination is a required deliverable of the 92201 service, not a separately billable product.2
- Physician interpretation and written report — The formal written analysis summarizing the examination findings, pathology identified, and clinical implications is bundled into 92201 and constitutes a required documentation element for billing validity.4
- Examination of both eyes when clinically indicated — Because CPT 92201 is “unilateral or bilateral,” examining both eyes during the same session generates only one unit of 92201 — bilateral examination is not separately reportable as two units.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 92202 | Ophthalmoscopy, extended; with drawing of optic nerve or macula (eg, for glaucoma, macular pathology, tumor) with interpretation and report, unilateral or bilateral | 92201 and 92202 are mutually exclusive sibling codes representing different anatomical targets of extended ophthalmoscopy — 92201 is for peripheral retinal pathology requiring scleral depression, while 92202 is for optic nerve or macular pathology. Do not report both on the same date of service for the same patient; payers will bundle or deny the second code. If both a peripheral retinal lesion and a macular/optic nerve lesion require extended evaluation on the same day, refer to payer-specific guidance — most payers allow only one extended ophthalmoscopy code per day.12 |
| 92004 | Ophthalmological services, new patient, comprehensive | A comprehensive eye exam (92004 or 92014) routinely includes dilated funduscopic examination. Any ophthalmoscopy performed as an integral part of that standard exam is bundled into the exam code. CPT 92201 is only separately reportable when the extended peripheral ophthalmoscopy with scleral depression is performed for a distinct, separately documented clinical indication beyond the scope of the routine comprehensive exam. Modifier -25 on the exam code may support same-day billing.3 |
| 92250 | Fundus photography with interpretation and report | Fundus photography is separately reportable when medically necessary and independently documented, but it should not be reflexively added to every 92201 encounter. If both are performed, each must have its own documented medical necessity, interpretation, and report. Bundling edits may apply by payer, and a modifier (-59) may be required to separately identify the photographic service.4 |
| 92228 | Remote imaging for monitoring and management of active retinal disease (eg, diabetic retinopathy) with physician review, interpretation, and report, unilateral or bilateral | Remote imaging codes and extended ophthalmoscopy codes represent fundamentally different service types (camera-based remote acquisition vs. real-time physician-performed indirect ophthalmoscopy). Do not substitute or cross-bill; each requires distinct technology, workflow, and physician involvement. |
Bundling Alert
The most significant bundling risk for CPT 92201 occurs when it is billed alongside a comprehensive eye exam (92004 or 92014) on the same date. Payers — including Medicare — may automatically bundle 92201 into the exam code and deny it absent a modifier and strong, separate documentation of medical necessity. If a patient presents for their annual comprehensive exam and, during that visit, the physician also discovers a peripheral retinal tear requiring extended BIO with scleral depression and a retinal drawing, the 92201 is separately reportable with modifier -25 on the exam code to signal a significant, separately identifiable service. The exam note and the 92201 interpretation/report must be discrete, individually complete documents. Do not rely on modifier -25 alone without documentation — it is the supporting medical record, not the modifier, that defends the claim at audit.23

Bilateral Billing Rules
CPT 92201** carries a bilateral indicator of 2, which means the Medicare Physician Fee Schedule payment already accounts for the possibility of bilateral performance — you are paid the same amount whether you examine one eye or both, and the fee is not doubled for bilateral exams. Never append modifier -50 (Bilateral Procedure), -RT (Right Side), or -LT (Left Side) to CPT 92201; doing so is both clinically inappropriate (the code descriptor already says “unilateral or bilateral”) and will cause incorrect payment or claim rejection.12 Report only one unit of 92201 per encounter, regardless of the number of eyes examined. Some private payers may have different billing instructions — always verify with individual payer contracts — but Medicare and most commercial payers following Medicare guidelines follow the bilateral indicator 2 rule for this code.3
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -25 | Significant, Separately Identifiable E/M Service | Append -25 to the eye exam or E/M code (not to 92201) on the same date of service when a comprehensive or intermediate eye exam is also billed and represents a significant, separately identifiable service beyond the decision to perform extended ophthalmoscopy. The exam note must document clinical decision-making independent of the ophthalmoscopy service itself.2 |
| -59 | Distinct Procedural Service | Apply to 92201 (or use an appropriate X{EPSU} modifier) when a payer-specific bundling edit would otherwise package 92201 into another same-day diagnostic service and the two services are genuinely distinct with separate indications and documentation. Use only when clinically and documentarily justified — do not append reflexively. |
| -76 | Repeat Procedure by Same Physician | May be applicable in rare circumstances when a second, fully documented extended ophthalmoscopy with scleral depression and a new retinal drawing is performed in the same session for a new acute finding in a different area of the retina. Payer-specific guidance varies; verify before using. |
| -GQ | Via Asynchronous Telecommunications | Used when extended ophthalmoscopy results are interpreted and reported via a store-and-forward telehealth modality in applicable payer/state contexts. Verify telehealth eligibility for 92201 under current CMS and MAC policy. |
| -GT | Via Interactive Audio and Video | Applied when the service is delivered via real-time interactive telehealth. Confirm that CPT 92201 remains on the applicable CMS or payer telehealth-eligible procedure list for the date of service. |
| -52 | Reduced Services | Use if the extended ophthalmoscopy was initiated but only partially completed due to patient cooperation issues, media opacity, or clinical circumstances preventing complete peripheral examination, with documentation of the reason for incomplete service. Expect reduced reimbursement. |
| -53 | Discontinued Procedure | Apply if the procedure was initiated but had to be terminated before any clinically useful examination or drawing was produced, due to a significant adverse event or patient emergency. |
Modifiers NOT applicable to 92201
🩺 Common ICD‑10‑CM Pairings
Primary Diagnosis Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| H33.311 | Horseshoe tear of retina without detachment, right eye | No | The most common acute indication for 92201; flap tear at posterior margin of vitreous attachment is the highest-risk tear type for progression to RD. Code to laterality; left eye is H33.312, bilateral is H33.313.3 |
| H33.001 | Unspecified retinal detachment with retinal break, right eye | No | Use when a retinal detachment is present and the specific type of break cannot be further specified from documentation. Prefer more specific codes (H33.011 for superotemporal, etc.) when laterality and break type are documented. |
| H33.191 | Other retinoschisis and retinal cysts, right eye | No | Extended ophthalmoscopy with scleral depression is the gold standard for differentiating degenerative retinoschisis from flat retinal detachment — a key diagnostic distinction with very different management implications.4 |
| H49.811 | Kearns-Sayre syndrome, right eye | No | Pigmentary retinopathy associated with this mitochondrial disorder may require peripheral retinal mapping; use only if supported by documentation. |
| D31.21 | Benign neoplasm of right retina | No | Peripheral retinal tumors (e.g., cavernous hemangioma, astrocytic hamartoma) require detailed mapping with 92201; confirm histological or clinical characterization before selecting benign vs. malignant codes. |
Secondary Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| H35.411 | Lattice degeneration of retina, right eye | No | Common secondary finding during extended ophthalmoscopy; lattice with or without atrophic holes frequently drives the decision to perform 92201 for peripheral retinal mapping and surveillance.2 |
| H59.021 | Cataract (lens) fragments in vitreous following cataract surgery, right eye | No | Dropped nuclear fragments can displace anteriorly and cause peripheral retinal traction; 92201 may be performed to evaluate the peripheral retina in the post-op setting. |
Etiology / Complication
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| H43.811 | Vitreous degeneration, right eye | No | Posterior vitreous detachment (PVD) with associated vitreoretinal traction is a primary driver of peripheral retinal tears; 92201 is frequently performed at PVD diagnosis to rule out concurrent retinal breaks.1 |
| H33.331 | Multiple defects of retina without detachment, right eye | No | When multiple atrophic or punched-out holes are identified during extended ophthalmoscopy, this code captures the multiplicity finding; separate from the single horseshoe tear code.3 |
Coding Specificity Reminder
Nearly all retinal pathology ICD-10-CM codes require laterality specification (right eye, left eye, bilateral, or unspecified) — never default to an unspecified laterality code if the documentation clearly identifies which eye is affected. For retinal detachment codes (H33.0xx), the 6th character specifies detachment type (unspecified, partial, total, etc.) and the 7th character specifies laterality — always code to the full 7 characters. Lattice degeneration (H35.41x) and retinal tears (H33.3xx) similarly require laterality at the 6th or 7th character. Because CPT 92201 covers bilateral examination under one code, it is common for the ICD-10-CM diagnosis codes to reflect bilateral involvement (e.g., bilateral lattice degeneration) — use the bilateral-specific codes where they exist rather than reporting two laterality-specific codes.3
🏥 MS‑DRG Considerations
CPT 92201 is a Medicine/diagnostic ophthalmology service that does not independently drive MS-DRG assignment in the inpatient setting. When a patient is hospitalized for a retinal condition — such as a rhegmatogenous retinal detachment requiring surgical repair — the principal diagnosis and any performed surgical procedures (e.g., pars plana vitrectomy, scleral buckle) are what determine DRG assignment under MDC 02 (Diseases and Disorders of the Eye). In that scenario, the ophthalmologist may perform CPT 92201 as a bedside pre-operative evaluation, which would be captured on the professional claim; the facility claim would reflect ICD-10-PCS codes for the operative procedures performed. Relevant DRGs in the inpatient retinal setting include DRG 121 (Acute Major Eye Infections with MCC/CC), DRG 124 (Other Disorders of the Eye with MCC), DRG 125 (Other Disorders of the Eye with CC), and DRG 126 (Other Disorders of the Eye without CC/MCC). CPT 92201 alone does not elevate DRG complexity or trigger CC/MCC capture — the retinal diagnosis codes attached to the claim are what matter for complexity stratification.4
🔧 ICD‑10‑PCS Equivalents
Note
CPT 92201 is a diagnostic visualization and documentation procedure. ICD-10-PCS captures diagnostic examination procedures under Section 4 (Measurement and Monitoring) for physiological measurements or Section B (Imaging) for image-based diagnostics. There is no PCS code that fully mirrors the “scleral depression + retinal drawing” workflow; the closest PCS root operations are Inspection (visual/manual examination of a body part) and Monitoring for ongoing assessment.
| PCS Code | Full Description | Modality |
|---|---|---|
| 08JXZZZ | Inspection of Eye, External Approach | Diagnostic visual inspection of the eye — nearest PCS equivalent for physician-performed ophthalmoscopic examination without a device |
| 4A07XVZ | Measurement of Eye, Ophthalmologic, External Approach | Measurement of ophthalmologic parameters — applicable to broader diagnostic eye measurement |
| 4A17XVZ | Monitoring of Eye, Ophthalmologic, External Approach | Serial/repeated ophthalmologic monitoring — most applicable when extended ophthalmoscopy is performed repeatedly over an admission |
| 08B0XZZ | Excision of Eye, External Approach | Included for reference only — applicable to tumor-related encounters where a retinal biopsy may follow diagnostic 92201; not a direct equivalent |
PCS Character Analysis (using 08JXZZZ as primary example)
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical — the broadest PCS section covering physician-performed procedures on body parts. |
| 2 | Body System | 8 | Eye — encompasses the entire ocular structure including the retina, vitreous, and sclera. |
| 3 | Root Operation | J | Inspection — defined as visually and/or manually exploring a body part; most accurately reflects the extended ophthalmoscopic examination component of 92201. |
| 4 | Body Part | 0 | Eye, Right — retinal inspection is captured under the globe-level body part value; there is no PCS-specific “peripheral retina” body part distinction. |
| 5 | Approach | X | External — the indirect ophthalmoscope and scleral depressor act on the external surface of the eye (eyelid/conjunctiva) and through the dilated pupil without incision. |
| 6 | Device | Z | No Device — no implant or inserted device is used during diagnostic ophthalmoscopy; the scleral depressor is a non-implanted, temporary instrument. |
| 7 | Qualifier | Z | No Qualifier — no additional specification is required for this inspection procedure in the PCS table. |
Root Operation Comparison
- Inspection (J) vs. Measurement (0, Section 4): Use Inspection (08JXZZZ) when the intent is physician visual examination and exploration of the retina — this maps most directly to the clinical act of indirect ophthalmoscopy. Use Measurement (4A07XVZ) when the intent is quantifying a specific physiological parameter (e.g., IOP, visual function) rather than visual exploration of anatomy.
- PCS Section 0 vs. Section B (Imaging): If retinal photography or imaging technology is used as part of the encounter (e.g., ultra-widefield fundus imaging), Section B (Imaging) codes using the Eye body system (B80xx) would apply for image-based services. CPT 92201, however, is a real-time physician-performed examination, not an image acquisition service, so Section 0 (Medical and Surgical — Inspection) or Section 4 (Measurement and Monitoring) are the closer functional equivalents.
- Inpatient applicability note: ICD-10-PCS ophthalmoscopy/inspection codes are rarely reported on UB-04 facility claims for diagnostic eye exams in the inpatient setting unless the facility has a specific policy to capture diagnostic examination procedures in PCS. The ophthalmologist’s professional services are captured on the CMS-1500/professional claim using CPT codes.
📝 Coding Examples
Example 1 — New Symptomatic PVD with Peripheral Retinal Tear Discovered
Clinical Scenario:
A 54-year-old new patient with high myopia presents urgently reporting one week of new-onset floaters and photopsia in the right eye. The physician performs a comprehensive new patient eye examination, documents anterior segment findings, vitreous status, and confirms an acute posterior vitreous detachment. During the same visit, the physician performs extended binocular indirect ophthalmoscopy with 360° scleral depression of the peripheral retina, identifying a horseshoe tear at the 10-o’clock position in the far periphery of the right eye with associated vitreoretinal traction. A detailed, labeled retinal diagram is created marking the tear’s clock-hour location, its relationship to the equator and ora serrata, and the flap configuration. The physician authors a separate written interpretation and report documenting the tear, the absence of sub-retinal fluid, and the plan for urgent laser retinopexy. No procedure is performed at today’s visit.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 92004-25 | Comprehensive new patient eye exam; modifier -25 appended to the exam code to indicate a significant, separately identifiable service was rendered beyond the decision to perform extended ophthalmoscopy. The exam included anterior segment, vitreous, and general posterior segment evaluation with distinct medical decision-making.2 |
| CPT 2 | 92201 | Extended ophthalmoscopy with scleral depression of peripheral retina, retinal drawing, interpretation and report. Single unit regardless of number of quadrants examined. No laterality modifier appended.1 |
| PDx | H33.311 | Horseshoe tear of retina without detachment, right eye — the primary finding driving the acute presentation and the extended ophthalmoscopy service. |
Note
Modifier -25 must be on the exam code (92004), not on 92201. Both the exam note and the 92201 interpretation/report must be discrete, complete documents in the medical record — a single combined note that doesn’t clearly separate the two services is a common audit vulnerability. Verify with your MAC whether an LCD exists for extended ophthalmoscopy that specifies additional documentation requirements beyond CPT and AMA guidelines.3
Example 2 — Surveillance of Known Peripheral Choroidal Lesion, Established Patient
Clinical Scenario:
A 61-year-old established patient with a previously documented peripheral choroidal nevus in the left eye returns for a 6-month surveillance visit. No comprehensive eye examination is performed today — the physician’s visit is specifically to re-evaluate the peripheral lesion. Extended binocular indirect ophthalmoscopy with scleral depression is performed, focusing on the nasal periphery of the left eye where the lesion was previously mapped at the 3-o’clock position. The physician creates an updated retinal drawing comparing the current lesion size and appearance to the prior drawing, documents no change in elevation, pigmentation, or associated subretinal fluid, and writes a formal interpretation and report concluding the nevus is stable and does not yet meet criteria for malignant transformation. No eye exam is billed today.
| Field | Code | Rationale |
|---|---|---|
| CPT | 92201 | Extended ophthalmoscopy with scleral depression and retinal drawing, interpretation and report, left eye (unilateral). Modifier -LT is NOT appended — bilateral indicator 2 means laterality modifiers are not used. Single unit billed.12 |
| PDx | D31.22 | Benign neoplasm of left retina — the established diagnosis driving the surveillance extended ophthalmoscopy. Use the left-eye specific code. |
Warning
Do not bill a separate E/M or eye exam code today when the only service performed is the extended ophthalmoscopy surveillance. Billing both a minimal or brief E/M and 92201 on the same day without a -25 modifier and distinct documentation supporting both services is a common overcoding pattern flagged by RAC and MAC audits. If the physician’s visit today was exclusively to perform and interpret the extended ophthalmoscopy, only 92201 is reportable.4
Example 3 — Bilateral Lattice Degeneration with Multiple Retinal Holes, Established Patient, No Concurrent Exam
Clinical Scenario:
A 38-year-old highly myopic established patient returns for annual peripheral retinal surveillance as previously planned. Both eyes have documented lattice degeneration; the right eye has a known atrophic hole that has been stable for two years. The physician performs BIO with full 360° scleral depression of both eyes. In the right eye, the atrophic hole remains unchanged; three new lattice lesions are identified in the left eye at 9, 10, and 11 o’clock. A complete bilateral retinal drawing is created for both eyes documenting all lesions by clock-hour position, extent, and characteristics. The physician writes a detailed interpretation and report noting new left eye lattice degeneration and recommending laser prophylaxis for the left eye lesions.
| Field | Code | Rationale |
|---|---|---|
| CPT | 92201 | Extended ophthalmoscopy, bilateral, with scleral depression and retinal drawing, interpretation and report. One unit only — the bilateral indicator 2 means bilateral examination is not reported as two units and no -50 modifier is used.13 |
| PDx | H35.413 | Lattice degeneration of retina, bilateral — report the bilateral-specific code because both eyes are affected and documented. Do not report H35.411 (right) and H35.412 (left) separately when a bilateral code exists.3 |
Global period reminder
CPT 92201 carries a global period of 000, so there is no post-procedure period — only the day of service is bundled into the payment. If this patient subsequently undergoes laser retinopexy (CPT 67145) within the coming days, the 92201 performed at this diagnostic visit is separately billable from the laser procedure, as they occur on different dates of service and have independent global packages. The diagnostic extended ophthalmoscopy that leads to the decision to perform laser may also be separately reportable on the day of the laser procedure if the physician performs a new 92201 immediately before the laser to re-confirm and re-map the lesion — document carefully to support both services.4
⚠️ Common Coding Pitfalls
- Pitfall 1 — Billing 92201 without a qualifying retinal drawing: The CPT descriptor explicitly requires a retinal drawing. A detailed written narrative of peripheral retinal findings does not substitute for an actual, labeled anatomical drawing of the pathology. This is consistently the #1 audit finding for this code, and its absence makes the claim indefensible at review. Every 92201 encounter must have a drawing in the medical record.3
- Pitfall 2 — Appending -RT, -LT, or -50: Because CPT 92201 is “unilateral or bilateral” with a bilateral indicator of 2, laterality and bilateral modifiers are never appropriate. Appending them will result in claim edits or incorrect payment. This is a well-documented compliance error in high-volume retina practices.12
- Pitfall 3 — Billing two units of 92201 for bilateral exams: Some coders or providers mistakenly report two units of 92201 (or one unit per eye) when both eyes are examined. CPT 92201 is reported once per encounter regardless of laterality. Reporting multiple units is an overpayment that is recoverable under Medicare audit.1
- Pitfall 4 — Using retired codes 92225 or 92226: CPT codes 92225 (Extended ophthalmoscopy, initial) and 92226 (Extended ophthalmoscopy, subsequent) were deleted effective January 1, 2018, and replaced by 92201 and 92202. These codes are no longer valid and must not be used on any claim. Using deleted codes will result in automatic claim rejection.2
- Pitfall 5 — Failing to append -25 on the same-day eye exam: When a comprehensive or intermediate eye exam and extended ophthalmoscopy are both performed and billed on the same day, modifier -25 must be placed on the exam code to signal a significant, separately identifiable service. Omitting -25 from the exam code (or incorrectly placing it on 92201) is a frequent billing error that leads to claim denial of the exam code or 92201.23
- Pitfall 6 — Documenting the retinal drawing as a generic stock image: Some EHR systems auto-populate a standardized retinal diagram with no patient-specific markings. Submitting a blank or generic diagram as the “retinal drawing” for 92201 does not meet documentation requirements. The drawing must be individualized, labeled with the specific pathology, its clock-hour location, and anatomical relationships, and it must reflect the actual findings observed in that particular patient at that particular visit.4
