What 15101 covers

Code 15101 represents additional area covered with an autologous split-thickness skin graft on the trunk, arms, or legs. In this procedure, the surgeon takes a thin layer of the patient’s skin from a donor site and transfers it to a wound, such as a burn or a defect left after tissue removal. Plastic, burn, and other surgeons may perform the graft in an operating room or another surgical setting.

Report 15101 only with the initial-area code 15100. It represents each additional 100 square centimeters, or each additional 1% of body surface area for infants and children. The operative report should identify the recipient site, graft type, and total area treated so the base and additional increments can be supported. CMS classifies 15101 as an add-on code: it is billed with the primary procedure and paid within that procedure’s global period.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

15101 billing questions

Can 15101 be reported by itself?

No. It is an add-on code and must be reported with the primary code 15100 for the initial grafted area.

How is the number of units determined?

Report a unit for each additional 100 square centimeters, or each additional 1% of body surface area for infants and children. Document the total recipient area and how it supports the reported increments.

When should 15121 be used instead?

Use the 15120/15121 code family for split-thickness grafting of designated sites such as the face, scalp, neck, hands, or feet. Code 15101 is for additional grafted area on the trunk, arms, or legs.

Does 15101 describe an epidermal graft?

No. It is for additional area treated with a split-thickness graft. The 15110/15111 family describes epidermal grafting on the trunk, arms, or legs.

What should the operative report support?

Document the split-thickness graft, recipient body site, total grafted area, and the initial and additional area increments. The primary graft procedure must also be reported.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
