What 15157 covers

This add-on represents an additional 1% of an infant’s or child’s body surface area treated with a tissue-cultured allogeneic skin substitute graft on the face, scalp, neck, hands, feet, or genitalia. A burn or reconstructive surgeon may apply the graft during operative wound coverage, including treatment of extensive burns or other wounds requiring skin replacement. The site and the patient’s age and body size affect how the treated area is measured within this code family.

Report 15157 with the applicable primary graft code, such as 15155, when the treated area extends beyond the initial area and the additional area is measured in 1% body-surface increments. The operative record should support the treated site, graft application, and total area covered, with enough detail to distinguish each additional increment. CMS classifies this as an add-on code: it is billed only 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.

15157 billing questions

When is 15157 used instead of 15156?

Use 15157 for each additional 1% of body surface area in an infant or child. Code 15156 represents additional area measured in 100-square-centimeter increments.

Which primary code is reported with 15157?

Report it with the applicable initial graft code for the specified sites, such as 15155. It is an add-on code and is not reported by itself.

Which sites qualify for this code?

The code family covers graft application on the face, scalp, neck, hands, feet, or genitalia. The documentation should identify the treated site and support the additional 1% increment.

How many units should be reported?

Report a unit for each additional 1% of body surface area treated in an infant or child. Document the total area grafted so the reported increments can be supported.

How does CMS treat payment for 15157?

CMS treats 15157 as an add-on code billed only with a primary procedure. Payment is within that primary 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.
