What 15100 covers

The surgeon takes a thin layer of the patient’s own skin from a donor site and places it over a recipient wound on the trunk, arm, or leg. Common situations include coverage after burn treatment, wound excision, or traumatic skin loss. The code identifies the graft by its split-thickness type and recipient location, not by the donor site. It covers the first 100 square centimeters, or the corresponding 1% of body surface area for infants and children.

Select the code using the recipient site, graft type, and documented treated area; report 15101 for additional area increments. Documentation should identify the recipient site, graft type, area, and harvest and placement performed. The day-before preoperative visit and 90 days of related postoperative care are included in the 90-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

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.

15100 billing questions

When is 15100 used instead of 15120?

Use 15100 for a split-thickness graft placed on the trunk, arms, or legs. Code 15120 applies to the specified face, scalp, neck, hands, feet, or genital sites.

How is additional graft area reported?

15100 covers the first 100 square centimeters, or 1% of body surface area for infants and children. Report 15101 for additional area increments and document the total treated area.

Does 15100 include harvesting the donor skin?

The service includes taking and placing the patient’s split-thickness graft. Document the donor and recipient sites and the grafting work performed.

Can recipient-site preparation be reported separately?

A distinct surgical preparation of the recipient site may be reported with the graft when performed and documented; 15002 describes preparation on the trunk, arms, or legs.

Should modifier 50 be used for grafts on both sides?

No. CMS identifies bilateral adjustment as inappropriate for 15100. The descriptor and anatomy do not support modifier 50.

Can an assistant or co-surgeon be paid for 15100?

Medicare payment to an assistant at surgery is restricted for this service. Co-surgeons and team surgery are not permitted.

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.
