🪡 CPT 13132 — Complex Repair, Forehead, Cheeks, Chin, Mouth, Neck, Axillae, Genitalia, Hands and/or Feet; 2.6 cm to 7.5 cm
Quick Reference
wRVU: 4.66 | Global Period: 010 | Assistant Payable: No | Bilateral Indicator: 0 Rule: CPT 13132 carries a 010-day global period, so routine postoperative wound checks and suture removal within 10 days are bundled into the reimbursement. The reflected wRVU applies the 2026 CMS −2.5% efficiency adjustment to the historical baseline of 4.78, since this is a non-time-based procedural code subject to that reduction. This code covers a broad, mixed anatomic grouping spanning cosmetically sensitive facial subunits and functional zones like hands and feet, so site documentation must be precise to avoid crosswalk errors with the neighboring 13121 (scalp/arms/legs) and 13151/13152 (eyelids/nose/ears/lips) complex-repair families.
📋 Clinical Description
CPT 13132 describes complex repair of a wound measuring 2.6 cm to 7.5 cm at one or more of the following sites: forehead, cheeks, chin, mouth, neck, axillae, genitalia, hands, and/or feet. Per CPT Surgical Guidelines, complex repair requires techniques beyond simple layered closure, such as extensive undermining of adjacent tissue planes, placement of retention sutures, debridement of devitalized tissue, or scar revision performed at the time of the original wound repair rather than as a staged, later procedure.
This code occupies the mid-length tier of its complex-repair family: 13131 covers the shorter 1.1-2.5 cm tier at the same sites, and add-on code 13133 is reported in conjunction with either base code for each additional 5 cm of repaired length beyond the primary code’s range. It is distinguished from 13121, which applies identical complexity criteria to the scalp, arms, and legs instead, and from 12042, which covers intermediate (layered but not complex) repair at the neck, hands, feet, and genitalia in the same 2.6-7.5 cm length tier.
This procedure may be performed in the following clinical contexts:
- Post-Mohs or post-excision facial reconstruction — A cheek or chin defect following excision of a skin lesion requires extensive undermining and layered closure to restore contour and minimize scarring.
- Trauma-related hand or foot laceration — A deep, gaping laceration to the hand from a mechanical injury requires debridement of devitalized tissue and retention sutures for structural support.
- Inpatient management of a complicated surgical wound — A dehisced neck or axillary incision with significant tissue separation requires extensive undermining and layered closure during an inpatient stay.
- Genital or perineal trauma repair — A complex genital laceration requiring meticulous layered closure and possible scar revision is repaired under regional or general anesthesia.
- Combined excision and complex closure — Excision of a keloid or scar contracture on the chin or neck is followed by complex closure of the resulting defect in the same operative session.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Extensive Undermining | Adjacent tissue planes are surgically separated from underlying structures well beyond the wound edge to reduce closure tension and allow tissue advancement, a technique distinctly more involved than the limited undermining sometimes performed in intermediate repair. | The operative note must specify the extent of undermining (e.g., distance in centimeters or tissue planes involved) since minimal or unspecified undermining does not meet complex-repair criteria and risks downcoding to intermediate repair. |
| Retention Suture Placement | Heavy-gauge retention sutures are placed through multiple tissue layers to relieve tension on the primary closure line, typically used in high-tension areas like the hands or where wound edges resist standard approximation. | Retention sutures are a hallmark complex-repair indicator; their placement should be explicitly documented, including suture type and location, to withstand audit scrutiny. |
| Debridement and Scar Revision | Devitalized or contaminated tissue is excised from the wound bed, and, when performed at the same session, existing scar tissue may be revised to improve the eventual cosmetic or functional outcome before layered closure is completed. | When debridement is extensive enough to meet the separate reporting threshold under CPT guidelines, it may be reported in addition to 13132 with modifier -59, but routine wound-bed cleansing incidental to closure remains bundled into this code. |
Clinical Pearl
The differentiator between 13132 and a lower-complexity code at the same length tier is not wound size but documented technique: extensive undermining, retention sutures, debridement of devitalized tissue, or scar revision must be explicitly described in the operative note. Payers frequently downcode complex repair claims to intermediate repair when the documentation only states “complex closure performed” without describing which specific technique elevated the repair beyond layered closure.
✅ Procedure Includes
- Local, regional, or general anesthesia administered based on wound extent and patient tolerance.
- Debridement of devitalized, contaminated, or necrotic tissue from the wound bed.
- Extensive undermining of adjacent tissue planes to reduce closure tension.
- Placement of retention sutures when needed for structural support at high-tension sites.
- Scar revision performed contemporaneously with the primary wound closure.
- Layered closure of deep and superficial tissue planes using appropriate suture technique.
- Meticulous skin-layer closure to optimize cosmetic and functional outcome.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 13131 | Complex repair, same sites, 1.1 cm to 2.5 cm | Mutually exclusive by wound length; if the total repaired length falls below 2.6 cm, 13131 applies instead of 13132 for the same wound. |
| 12042 | Intermediate repair, neck/hands/feet/genitalia, 2.6 cm to 7.5 cm | Mutually exclusive by repair complexity; if the operative note documents only layered closure without extensive undermining, debridement, or retention sutures, 12042 applies instead. |
| 13121 | Complex repair, scalp/arms/legs, 2.6 cm to 7.5 cm | Anatomically distinct code family; a scalp or leg wound repaired with identical complex technique is reported under 13121, not 13132, despite the shared length tier. |
| 17311 | Mohs micrographic surgery, first stage | Frequently bundled under NCCI edits when complex repair follows Mohs excision at the same session; modifier -59 may be required to override the edit when the repair is a distinct, separately identifiable service, but documentation must clearly support the distinction. |
Bundling Alert
CPT 13132 carries a 010-day global period, so related postoperative wound checks within 10 days are bundled and not separately billable, while an unrelated E/M service during that window requires modifier -24 to be separately payable. NCCI edits commonly bundle 13132 with certain excision and Mohs surgery codes performed at the same session, so modifier -59 (or a more specific X-modifier) must be supported by clear documentation that the repair represents distinct, separately identifiable work rather than routine wound closure incidental to the excision itself, since inappropriate modifier use here is a frequent audit trigger.

Bilateral Billing Rules
Modifier -50 is not appropriate for 13132 because CPT repair guidelines require summing wound lengths within the same anatomic classification into a single reported code rather than applying a bilateral payment adjustment for symmetric sites such as bilateral hands. -RT and -LT remain useful for clean claim submission and internal tracking at single, clearly unilateral sites like one hand or one axilla, but they do not independently trigger a bilateral fee increase for this code family.
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -RT | Right Side | Apply to indicate laterality when the complex repair is performed at a single, clearly unilateral site such as one hand, foot, or axilla. |
| -LT | Left Side | Apply to indicate laterality when the complex repair is performed at a single, clearly unilateral site such as one hand, foot, or axilla. |
| -25 | Significant E/M | Apply when a separately identifiable, medically necessary E/M service is performed the same date, distinct from the decision to perform the complex repair. |
| -59 | Distinct Service | Apply when the repair is a distinct, separately identifiable service from another bundled procedure performed at the same session, such as an excision or Mohs surgery code, with documentation supporting the distinction. |
| -51 | Multiple Procedures | Apply when 13132 is reported alongside other separately payable procedures performed in the same session, subject to multiple-procedure payment reduction. |
| -22 | Increased Procedural Services | Apply when the repair required substantially more work than typical for the code, such as unusually extensive undermining or multiple retention suture sites, with documentation quantifying the added complexity. |
| -76 | Repeat Procedure, Same Physician | Apply when the same provider repeats a complex repair on a new, unrelated wound for the same patient later the same day. |
| -77 | Repeat Procedure, Different Physician | Apply when a different physician performs a repeat complex repair on the same patient later the same day. |
| -52 | Reduced Services | Apply when the repair is intentionally reduced in scope, with documentation of the reduced extent. |
| -53 | Discontinued | Apply when the repair is started but discontinued before completion due to patient instability or intolerance. |
| -58 | Staged | Apply when a planned related procedure on the same wound, such as staged scar revision, is performed within the 10-day global period. |
| -78 | Return to OR | Apply when an unplanned related return to the operating or procedure room occurs within the global period due to a complication of this repair. |
| -79 | Unrelated Procedure | Apply when an unrelated procedure is performed by the same physician within the 10-day global period, unconnected to the original wound repair. |
🩺 Common ICD-10-CM Pairings
Primary Diagnosis Group
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| S01.81XA | Unspecified open wound of other part of head, initial encounter | No | Supports repair at the forehead when a more site-specific code is unavailable; confirm the operative note localizes the wound to the forehead subunit. |
| S01.421A | Laceration without foreign body of left cheek and temporomandibular area, initial encounter | No | Facial subunit-specific pairing for cheek wounds; laterality must match the operative documentation exactly. |
| S01.512A | Laceration without foreign body of lip, initial encounter | No | Supports repair at the mouth/lip site; confirm the wound involves the lip rather than an adjacent oral mucosal structure, which may carry a different code. |
| S61.409A | Unspecified open wound of right hand, unspecified, initial encounter | No | Hand-site pairing; specificity beyond “unspecified” should be used when the operative note identifies a more precise hand location or structure involved. |
| S91.301A | Unspecified open wound, right foot, initial encounter | No | Foot-site pairing; confirm no tendon, nerve, or deeper structure involvement, which would require additional or alternate coding beyond the integumentary repair itself. |
Secondary Group
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| W45.8XXA | Other foreign body or object entering through skin, initial encounter | No | Applicable external-cause code when a foreign body contributed to the wound requiring debridement before complex closure. |
| Y92.9 | Unspecified place or not applicable | No | General place-of-occurrence code used when a more specific location is not documented. |
Etiology / Complication
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| T81.31XA | Disruption of external operation (surgical) wound, not elsewhere classified, initial encounter | No | Applies when 13132 is used to complex-repair a significantly dehisced surgical incision rather than a traumatic wound. |
| L76.32 | Postprocedural hematoma of skin and subcutaneous tissue following a procedure | No | Applies when the wound requiring complex repair resulted from a postprocedural hematoma requiring extensive undermining and layered closure after evacuation. |
Coding Specificity Reminder
Confirm the exact anatomic subunit — forehead versus cheek versus chin versus mouth — since ICD-10-CM offers more granular site-specific codes than a generic “unspecified” selection whenever the operative note supports it. Verify laterality and initial-versus-subsequent encounter status match the documentation precisely, and distinguish traumatic wound etiology from postprocedural dehiscence or hematoma, since this changes both the diagnosis code family and the clinical narrative supporting medical necessity. Always confirm the operative note documents a complex-repair-qualifying technique (extensive undermining, retention sutures, debridement, or scar revision) rather than simple layered closure, since this is the most heavily audited distinction for this code family.
🏥 MS-DRG Considerations
CPT 13132 is reported on the professional fee claim and, on the inpatient facility side, may support a low-weighted integumentary surgical DRG if the corresponding ICD-10-PCS repair code is designated as the principal procedure for the admission, though this is uncommon since complex wound repairs are more frequently secondary to a more significant admitting diagnosis. When performed incidental to a primary surgical procedure or trauma admission, the facility-side PCS repair code typically does not independently elevate DRG severity weighting. Facility coders should verify whether the complex repair represents the primary reason for the inpatient stay or a secondary intervention, since this materially affects DRG selection and resource-intensity classification. Coders should ensure the pro-fee claim for 13132 is evaluated independently of the facility DRG methodology, as the two billing streams follow separate payment logic.
🔧 ICD-10-PCS Equivalents
| PCS Code | Full Description | Modality |
|---|---|---|
| 0HQ0XZZ | Repair skin, scalp, external approach | Open/External Repair |
| 0HQ1XZZ | Repair skin, face, external approach | Open/External Repair |
| 0HQMXZZ | Repair skin, right foot, external approach | Open/External Repair |
| 0HQ4XZZ | Repair skin, right upper extremity, external approach | Open/External Repair |
PCS Character Analysis
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical, the section covering the vast majority of therapeutic inpatient procedures. |
| 2 | Body System | H | Skin and Breast, the body system governing integumentary repair procedures regardless of repair complexity. |
| 3 | Root Operation | Q | Repair, defined as restoring a body part to its normal anatomic structure and function by any means, which applies equally to simple, intermediate, and complex CPT-level repairs. |
| 4 | Body Part | 0/1/M/4 | Specifies the site involved (scalp, face, right foot, right upper extremity); other sites within this CPT code’s scope use distinct body part values not shown above. |
| 5 | Approach | X | External, reflecting that the repair is performed directly on the skin surface without instrumentation through a body orifice or percutaneous access. |
| 6 | Device | Z | No device, since suture, staple, or adhesive-based closure does not involve an implanted or left-in device under PCS conventions. |
| 7 | Qualifier | Z | No qualifier, as this procedure does not require further specification beyond the root operation and body part. |
Root Operation Comparison
- Repair (Q) applies uniformly across CPT-level simple, intermediate, and complex closures in PCS, since PCS does not distinguish repair complexity the way CPT does — that distinction lives entirely in the CPT code selection, not the PCS code.
- This contrasts with root operation Excision, used when tissue such as a scar or lesion is cut out and removed rather than reapproximated, which would apply to a separately reported excisional procedure performed before this repair.
- Facility coders should not assume a more resource-intensive PCS code applies simply because the CPT-level repair is complex rather than simple or intermediate, since PCS repair coding remains identical across that CPT complexity distinction.
📝 Coding Examples
Example 1
Clinical Scenario: A 52-year-old male inpatient sustains a 4.5 cm deep laceration to the right hand from a workplace machinery accident during a hospital-based occupational injury evaluation. The consulting hand surgeon debrides devitalized tissue from the wound margins, performs extensive undermining to reduce tension, and places retention sutures before completing a layered closure. The operative note explicitly documents each technique used to justify the complex-repair classification. No tendon or nerve injury is identified.
| Field | Code | Rationale |
|---|---|---|
| CPT | 13132-RT | The 4.5 cm hand wound falls within the 2.6-7.5 cm tier, and the documented debridement, extensive undermining, and retention sutures meet complex-repair criteria; modifier -RT confirms the unilateral right-hand site. |
| PDx | S61.409A | Right hand open wound, initial encounter, correctly reflects the traumatic mechanical injury supporting the repair. |
Note
Ensure the operative note explicitly names each complex-repair-qualifying technique performed, since generic language like “complex closure” without technique detail is a leading cause of payer downcoding to intermediate repair.
Example 2
Clinical Scenario: A patient undergoes excision of a large facial keloid on the chin, followed by a 6.0 cm complex closure of the resulting defect requiring extensive undermining and meticulous layered technique to restore contour. The excision and repair are performed in the same operative session by the same surgeon, with clear operative documentation distinguishing the excision work from the separately identifiable complex repair performed afterward.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 11446 | Excision of the chin keloid lesion is reported as the primary excisional procedure. |
| CPT 2 | 13132-59 | The 6.0 cm complex repair of the resulting defect is a distinct, separately identifiable service from the excision itself, supported by modifier -59 to override the applicable NCCI bundling edit. |
| PDx | T81.31XA | Not applicable here; a keloid-specific diagnosis code should instead be used as the primary diagnosis supporting the excision, with the repair coded as a secondary procedure tied to the same encounter. |
Warning
NCCI edits frequently bundle complex repair codes with excision codes performed at the same session; modifier -59 (or a more specific X-modifier) must be supported by clear documentation that the closure represents meaningfully distinct additional work, not simply the routine closure of the excision site.
Example 3
Clinical Scenario: An inpatient develops significant dehiscence of a neck surgical incision six days after an unrelated thyroid procedure, with wound edges separated and underlying tissue exposed requiring extensive undermining before re-closure. The consulting surgical team performs debridement of a small amount of devitalized tissue at the wound edges, extensive undermining to achieve tension-free closure, and layered re-approximation totaling 3.2 cm in length. This is documented as a distinct, medically necessary intervention.
| Field | Code | Rationale |
|---|---|---|
| CPT | 13132 | The 3.2 cm neck wound falls within the 2.6-7.5 cm tier, and the documented debridement plus extensive undermining meet complex-repair criteria. |
| PDx | T81.31XA | Disruption of external operation wound, initial encounter, accurately reflects the postoperative dehiscence etiology. |
Global period reminder
Because 13132 carries its own 010-day global period, any related follow-up wound check within 10 days of this repair is bundled into this code’s reimbursement; verify the original thyroid surgery’s separate global period status independently, since that procedure may still carry active global days affecting other billing decisions for the same patient.
⚠️ Common Coding Pitfalls
- Pitfall 1: Billing 13132 based solely on wound length without documented complex-repair technique, when the operative note only supports layered closure meeting intermediate-repair criteria under 12042.
- Pitfall 2: Failing to append modifier -59 (or a more specific X-modifier) when 13132 is reported alongside a bundled excision or Mohs surgery code, risking denial of the repair as included in the primary procedure.
- Pitfall 3: Reporting 13132 for a scalp, arm, or leg site, which instead belongs to the separate 13121 complex-repair code despite overlapping length tiers.
- Pitfall 4: Omitting add-on code 13133 when total repaired length exceeds 7.5 cm, resulting in underbilling for the additional length actually repaired.
- Pitfall 5: Under-documenting the specific complex-repair technique used, with vague language like “complex closure performed,” creating audit vulnerability and risk of downcoding.
- Pitfall 6: Missing modifier -24 on an unrelated E/M service performed within the 10-day global period, leading to inappropriate denial as bundled into this code’s global package.
