Summary & Overview

CPT 15220: Free Full-Thickness Skin Graft, Scalp/Arms/Legs ≤20 cm²

CPT code 15220 represents a free full–thickness skin graft of the scalp, arms, and/or legs measuring 20 cm² or less. This surgical code captures a common reconstructive technique used to close small-to-moderate soft-tissue defects after trauma, excision, or chronic wound management. Nationally, accurate coding for full–thickness grafts affects clinical documentation, surgical quality metrics, and appropriate payer adjudication for surgical services.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for full–thickness grafting, typical sites of service, and what to expect in billing and claims workflows for this code. The publication outlines benchmarking considerations and typical payer coverage patterns where available, highlights common documentation elements relevant to procedure selection, and summarizes policy and coding nuances that influence payment and claim review. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 15220 describes a free full–thickness skin graft of the scalp, arms, and/or legs with a graft size of 20 cm² or less. This procedure involves harvesting full-thickness skin and transplanting it to a defect on the scalp, arm(s), and/or leg(s).

Service type: Surgical skin grafting (full-thickness skin graft)
Typical site of service: Operative setting such as an ambulatory surgery center or hospital operating room, and may also be performed in procedural suites where operative sterility and surgical support are available.

Clinical & Coding Specifications

Clinical Context

A 56-year-old male presents to the outpatient surgical clinic with a chronic nonhealing full-thickness scalp wound following excision of a malignant skin lesion. After outpatient evaluation, the surgeon determines that a free full-thickness skin graft is required to achieve durable coverage of the defect. Preoperative planning includes review of comorbidities, medication reconciliation, informed consent, and selection of a donor site on the thigh. The procedure is performed in an ambulatory surgery center under monitored anesthesia care. The surgeon excises devitalized tissue at the recipient site, harvests a full-thickness graft measuring less than or equal to 20 cm2 from the donor site, secures the graft to the scalp defect with sutures and a bolster dressing, and places routine postoperative dressings. Postoperative workflow includes recovery room monitoring, discharge with wound care instructions, a scheduled clinic visit for bolster removal and graft assessment within 5–7 days, and follow-up visits to monitor healing and address complications such as partial graft loss or infection.

Coding Specifications

Modifier	Description	When to Use
`50`	Bilateral procedure	When identical full-thickness grafts are performed on both left and right anatomic sites during the same operative session.
`51`	Multiple procedures	When this graft is reported in addition to other distinct surgical procedures at separate anatomic sites during the same operative session.
`52`	Reduced services	When the service is partially reduced or not completed as originally intended (for example, graft harvest abbreviated due to intraoperative findings).
`53`	Discontinued procedure	When the procedure is started but discontinued due to extenuating circumstances or those that threaten the patient.
`59`	Distinct procedural service	When another procedure on a separate anatomic site or a distinct service is performed the same day and not usually reported together.
`62`	Two surgeons	When two surgeons work together as primary surgeons performing distinct portions of the operation.
`78`	Return to OR for related procedure during postoperative period	When the patient returns to the operating room for a related procedure for complications during the global period (e.g., hematoma evacuation and graft revision).
`79`	Unrelated procedure or service by the same physician during the postoperative period	When an unrelated procedure is performed during the global period.
`76`	Repeat procedure by same physician (not in supplied list)	Data not available in the input.
`LT`	Left side	To indicate the procedure was performed on the left side when laterality is applicable.
`RT`	Right side	To indicate the procedure was performed on the right side when laterality is applicable.
`22`	Increased procedural services	When the work required to perform the graft is substantially greater than typically required (extensive debridement, difficult closure).
`53`	Discontinued procedure	When the procedure is terminated before completion.
`TC`	Technical component	When reporting only the technical component, such as when a facility bills separately for the technical portion.
