Summary & Overview
CPT 12045: Intermediate Repair of Superficial Wounds, 12.6–20.0 cm
CPT code 12045 designates the intermediate repair of superficial wounds on the neck, hands, feet, and/or external genitalia when the wound length is between 12.6 and 20.0 cm. As a commonly used surgical closure code, it defines billing and clinical documentation expectations for a mid-range complexity wound repair procedure. Nationally, accurate use of this code matters for proper payment, quality measurement, and clinical audit, especially in settings that frequently treat traumatic or surgical lacerations.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of code definition and clinical context, typical sites of service, common modifiers associated with procedural coding, and related coding considerations. The publication outlines typical documentation elements tied to this level of repair, expected service settings, and how this code fits into broader wound-care service lines.
This summary serves clinicians, billing professionals, and policy analysts seeking national-level guidance on the classification and use of CPT code 12045, operational benchmarks, and implications for revenue cycle and compliance. Data not available in the input are noted where applicable.
Billing Code Overview
CPT code 12045 describes the intermediate repair of superficial wounds located on the neck, hands, feet, and/or external genitalia measuring 12.6 to 20.0 cm. This procedure classification indicates an intermediate complexity closure, typically involving layered closure of subcutaneous tissues and/or extensive cleaning, debridement, or removal of foreign material.

Service type: Intermediate wound repair
-
Typical site of service: Ambulatory surgical centers, hospital outpatient departments, emergency departments, or physician offices equipped for minor surgical procedures

Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents to an urgent care or emergency department after sustaining a laceration to the dorsal hand when falling on broken glass. The wound is superficial but involves the skin and subcutaneous tissue without deep structural injury. After local anesthesia and thorough irrigation, the clinician determines the total length of wound edges requiring closure measures 15 cm; the repair is an intermediate closure (layered closure with buried absorbable sutures and skin approximation). The typical workflow includes triage, assessment for neurovascular or tendon injury, wound cleansing and debridement, local anesthetic administration, layered closure using absorbable sutures in the subcutaneous layer and nonabsorbable or absorbable skin sutures, application of dressing and postoperative instructions, and documentation of wound length, technique, anesthesia, and any complications. Typical sites of service are the urgent care clinic, emergency department, or outpatient ambulatory surgical center when performed for wounds of the hand, foot, neck, or external genitalia measuring 12.6 to 20.0 cm. Common payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Data not available in the input. | Data not available in the input. |
26 | Professional component | Use when reporting only the professional component of a clinical service if applicable (e.g., supervision of interpreted diagnostic testing related to the wound). |
50 | Bilateral procedure | Use when an equivalent intermediate repair of similar wounds is performed on both hands/feet/paired sites during the same encounter. |
51 | Multiple procedures | Use when multiple distinct procedures are performed at the same session in addition to the wound repair. |
52 | Reduced services | Use when the full service is not performed (for example, repair attempted but aborted due to patient instability). |
53 | Discontinued procedure | Use when the procedure is started but halted due to extenuating circumstances. |
59 | Distinct procedural service | Use to indicate a procedure or service not normally reported together but appropriate under the circumstances (e.g., separate wound repairs at anatomically distinct sites). |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of the repair (rare for simple intermediate repair). |
78 | Unplanned return to the operating/procedure room | Use when the patient returns to the OR/procedure suite for a related complication requiring repeat repair under the same general/anesthetic episode. |
