What 15121 covers

This add-on represents additional recipient area covered with a split-thickness skin graft on sites such as the face, scalp, neck, hands, feet, genitalia, or multiple digits. The graft uses a thin layer of the patient’s own skin. Plastic surgeons, burn surgeons, and other surgeons may use it for reconstruction after burns, trauma, or excision, often in an operating room or hospital setting.

Use 15121 only with the initial-area code 15120. The additional area is counted in 100-square-centimeter increments, or in 1% body-area increments for infants and children. Document the recipient site, graft type, patient age when relevant, and the measured graft area supporting the units reported. CMS classifies 15121 as an add-on code: it is billed with a 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.

15121 billing questions

Can 15121 be reported without 15120?

No. It is an add-on for additional split-thickness graft area and is reported with 15120 for the initial area.

How is the additional graft area counted?

Count additional area in 100-square-centimeter increments. For infants and children, the measure is each additional 1% of body area.

When should 15100 or 15101 be used instead?

Those split-thickness graft codes apply to the trunk, arms, or legs. Use the 15120/15121 site group for the face, scalp, neck, hands, feet, genitalia, or multiple digits.

How does 15121 differ from 15116?

Both are add-on codes for specified sites, but 15121 is for split-thickness grafting and 15116 is for epidermal grafting.

What documentation supports reporting 15121?

Record the graft type, recipient site, and measured area. For an infant or child, document the body-area measure used to support the additional units.

How does the global-period rule affect payment?

CMS identifies 15121 as an add-on billed with a primary procedure and paid within that procedure’s global period.

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.
