CPT Code 15115 is specifically designed to report the initial epidermal autograft performed on the face, scalp, hands, feet, or genitalia. Because these areas require increased surgical precision and carry greater functional and aesthetic implications, CPT 15115 differs from epidermal autograft codes used for the trunk and extremities.
Epidermal autografting plays a vital role in wound care and reconstructive surgery, especially when injuries involve functionally critical or cosmetically sensitive anatomical areas. Accurate coding of these procedures is essential to ensure appropriate reimbursement, regulatory compliance, and audit protection.
This guide explains CPT Code 15115, covering its use, documentation, coding, billing, and real-world examples to support accurate and compliant reporting.
CPT Code 15115 is defined as:
Epidermal autograft, face, scalp, hands, feet, or genitalia; first 100 square
centimeters, or first 1% of body surface area of infants and children
This code represents the base procedure for epidermal autografting performed on anatomically complex regions. It includes harvesting the epidermal layer from the patient’s own skin and transplanting it to the affected site.
Unlike add-on codes, CPT 15115 may be reported as a standalone primary code when the grafted area does not exceed the initial threshold.
The face, scalp, hands, feet, and genitalia are considered high-risk and high-impact anatomical sites due to:
For these reasons, CPT coding differentiates grafts performed on these areas from those applied to the trunk or extremities.
An epidermal autograft involves transferring a thin layer of epidermal skin from a donor site on the same patient to a wound requiring coverage. Common donor sites include the thigh or buttocks.
wounds are too large, deep, or complex to heal with conservative wound care alone.
CPT 15115 is typically supported by medical necessity for conditions such as:
Payers may also consider:
Successful epidermal autografting begins with proper preparation, which may include:
The procedure generally includes the following steps:
Procedure time varies based on graft size and anatomical complexity.
Recovery depends on wound severity and patient health, but typically involves:
Healing may take several weeks to months, especially for functionally demanding areas like hands and feet.
Report CPT 15115 when all of the following apply:
CPT 15115 applies only to:
Do not report CPT 15115 for trunk, arms, or legs.
Complete documentation should include:
Understanding how CPT Code 15115 is reimbursed helps providers and billing teams avoid payment delays, reduce denials, and maintain compliance with payer requirements.
Reimbursement for CPT Code 15115 varies by payer, geographic region, and site of service. Medicare reimbursement is often carrier-priced, meaning payment amounts are determined by local Medicare Administrative Contractors. Reviewing applicable Local Coverage Determinations (LCDs) is essential to understanding coverage and payment expectations.
Many commercial payers require prior authorization for epidermal autograft procedures, particularly when they involve sensitive anatomical areas or extensive grafting. Claims submitted without required authorization may be denied regardless of medical necessity.
Payment may differ between facility claims (hospital inpatient or outpatient settings) and professional claims (surgeon or provider services). Certain services may be bundled on facility claims while remaining separately reimbursable on professional claims, depending on payer policy.
Due to the complexity and cost of epidermal autografting, claims reported with CPT 15115 are frequently reviewed by payers. Detailed documentation supporting medical necessity, graft size, and anatomical location is critical to ensure timely reimbursement and reduce the risk of audits or post-payment recoupments.

| CPT Code | Description |
|---|---|
| 15115 | Epidermal autograft, first 100 cm² (special areas) |
| 15116 | Each additional 100 cm² (add-on) |
| 15110 | Epidermal autograft, trunk/arms/legs |
| 15111 | Each additional 100 cm², trunk/arms/legs |
| 15130–15131 | Dermal autografts |
| 15271–15278 | Skin substitute grafts |
The following scenarios demonstrate how CPT 15115 should be reported in common clinical situations, including correct code selection, surface area measurement, and documentation support.
Clinical Scenario:
A 52-year-old patient sustains second-degree burns to the face following a workplace
accident. An epidermal autograft is performed, covering an area of 85 cm².
Coding & Billing:
CPT 15115 – Epidermal autograft, first 100 cm²
Explanation:
The total grafted area does not exceed 100 cm². CPT 15115 alone accurately reports the
service, and no add-on code is required.
Clinical Scenario:
A patient undergoes Mohs surgery, resulting in a scalp defect. An epidermal autograft
measuring 140 cm² is applied.
Coding & Billing:
CPT 15115 – First 100 cm²
CPT 15116 × 1 unit – Additional 100 cm²
Explanation:
CPT 15115 covers the initial 100 cm². One full additional 100 cm² qualifies for CPT 15116.
The remaining 40 cm² is not billable.
Clinical Scenario:
A 4-year-old child sustains burns to the hand requiring epidermal autografting. The grafted
area totals 2% of body surface area (BSA).
Coding & Billing:
CPT 15115 – First 1% BSA
CPT 15116 × 1 unit – Additional 1% BSA
Explanation:
For pediatric patients, surface area is reported as a percentage of BSA. One add-on unit is
supported beyond the base allowance.
Clinical Scenario:
An adult patient receives epidermal autografts to the face and scalp during the same
operative session. The combined graft area totals 210 cm².
Coding & Billing:
CPT 15115 – First 100 cm²
CPT 15116 × 1 unit – Additional 100 cm²
Explanation:
Surface areas are combined when grafts are applied to covered anatomical regions in the same
session. The remaining 10 cm² is not billable.
Accurate use of CPT Code 15115 is essential for proper reimbursement and compliance when epidermal autografts are performed on highly sensitive and functionally important anatomical areas. Due to strict anatomical limitations, surface area thresholds, and documentation requirements, even minor errors can result in denials or delayed payments.
