What 15115 covers

A surgeon places an epidermal graft taken from the patient to cover a wound at a specified site: the face, scalp, neck, hands, feet, genitalia, or multiple digits. Plastic surgeons and burn surgeons may perform this coverage during operative treatment of burns or other wounds, in a hospital or ambulatory surgery setting. The special-site grouping distinguishes this code from epidermal grafting on the trunk, arms, or legs.

Report 15115 for the first 100 sq cm treated; for infants and children, the measure is each 1% of body area. Document the recipient site, grafted area, and patient age when the body-area measure is used. Code 15116 reports each additional unit. A 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery services are not paid, and 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.

15115 billing questions

When should 15115 be chosen instead of 15110?

Use 15115 for epidermal autograft coverage on the face, scalp, neck, hands, feet, genitalia, or multiple digits. Code 15110 is for the trunk, arms, or legs.

How are additional grafted areas reported?

15115 represents the first 100 sq cm, or each 1% of body area for an infant or child. Report 15116 for each additional unit.

How does 15115 differ from 15120?

Both cover the special-site group, but 15115 is for an epidermal autograft and 15120 is for a split-thickness autograft.

What documentation supports the area reported?

Record the recipient site and the area covered. For an infant or child, document the body-area percentage used to determine the unit count.

Can modifier 50 be used for grafting both sides?

No. The CMS bilateral adjustment does not apply to 15115, and modifier 50 is inappropriate.

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%. The 90-day global period includes the day-before preoperative visit and related postoperative care.

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.
