Summary & Overview
CPT 15103: Extension of Recipient Site Preparation for Skin Graft
CPT 15103 documents the extension of a recipient-site preparation for split-thickness skin grafting, covering an additional 100 cm2 at the same encounter when a provider has already prepared up to the initial 100 cm2. This code is used in surgical repair of wounds, burns, and scar contractures on the trunk, arms, or legs and includes a pediatric specification for children under 10 years where each additional 1 percent body area is reported. Nationally, accurate use of CPT 15103 affects coding consistency, billing clarity, and appropriate grouping of graft preparation services across surgical settings.
Key payers in the scope of this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare. The summary provides a concise reference for payers and providers to align on service definition and site expectations.
Readers will find: a clear description of clinical and procedural context for CPT 15103; common modifiers and related CPT codes to consider when bundling or sequencing surgical preparation and grafting services; typical diagnostic scenarios where this code is applicable (for example burns, pressure ulcers, and open wounds); and practical notes on typical sites of service. Data gaps are identified where input did not provide service line metadata. This brief equips billing professionals, practice managers, and policy analysts with the essential framework to interpret and apply CPT 15103 consistently in practice.
CPT Code Overview
CPT 15103 describes an extension of a surgical preparation performed at the same encounter when a provider prepares up to 100 cm2 of a body part with an open wound, burn eschar, or scar contracture to receive a skin graft, by extending the prepared site up to an additional 100 cm2. In children under 10 years old, CPT 15103 applies to each additional 1 percent of body area after the first.
Service type: Skin Replacement Surgery (Surgical Preparation)
Typical site of service: Likely hospital outpatient or surgical center. Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to a hospital outpatient surgical unit with a deep partial-thickness burn and adjacent scar contracture on the lateral thigh following a thermal injury. The surgeon plans a split-thickness skin graft to cover the prepared recipient site. At the same encounter the provider prepares the initial recipient site up to 100 cm2 and extends the preparation to an additional 100 cm2 to optimize graft placement and accommodate wound margins. Preoperative assessment includes wound measurement and documentation of burn depth, informed consent, and marking of the donor site. Intraoperatively the team performs surgical preparation of the recipient bed by excision of nonviable tissue and scar release, measures total prepared surface area, harvests the graft, and applies dressings. Postoperative workflow includes routine wound checks in the recovery area, discharge instructions, and arranged outpatient follow-up for graft assessment and dressing changes.

Related Diagnoses
-
T31.0— Burns involving less than 10% of body surfaceRelevant because limited total body surface burns may require localized recipient-site preparation and grafting on the trunk, arms, or legs.
-
T21.31XA— Burn of third degree of chest wall, initial encounterDeep full-thickness chest wall burns may require excision of eschar and preparation of recipient sites for grafting, consistent with the procedure described.
-
L89.152— Pressure ulcer of sacral region, stage 2Pressure ulcers create open wounds that may need surgical preparation and possible grafting when conservative measures fail; this code identifies a possible clinical indication for recipient-site preparation.
-
S81.802A— Unspecified open wound, left lower leg, initial encounterOpen traumatic wounds on the lower leg are potential recipient sites for skin grafting after surgical preparation.
-
L97.909— Non-pressure chronic ulcer of unspecified lower leg with unspecified severityChronic lower leg ulcers that do not heal may require excision of nonviable tissue and grafting; this diagnosis aligns with the need for recipient-site preparation described by

Related CPT Codes
| CPT Code | Description | Relationship to 15103 |
|---|---|---|
15100 | Split-thickness autograft, trunk, arms, legs; first 100 sq cm or less | Initial donor graft procedure that commonly pairs with recipient-site preparation; often billed with 15100 when graft harvest is performed. |
15101 | Split-thickness autograft, trunk, arms, legs; each additional 100 sq cm, or part thereof | Billed for additional harvested graft area beyond the first 100 sq cm; parallels 15103 which addresses additional prepared recipient site area. |
15002 | Surgical preparation or creation of recipient site by excision of open wounds, burn eschar, or scar | Closely related as an alternative or complement for recipient-site preparation; 15002 may describe creation/excision while 15103 describes extension of preparation at the same encounter. |
15271 | Application of skin substitute graft to trunk, arms, legs, total wound surface area up to 100 sq cm | Alternative skin replacement approach (skin substitute) for similar recipient sites; may be used instead of autograft-related codes depending on graft material and technique. |
Common pairings and alternatives:
-
15103is commonly used with15100or15101when autograft harvest and recipient-site preparation occur in the same operative session. -
15002may be used for primary excision/creation of the recipient site;15103documents extending the prepared site beyond the initial 100 cm2 at the same encounter. -
15271represents an alternative treatment using skin substitutes rather than autograft techniques.
