What 15278 covers

This add-on reports additional wound area treated with a skin substitute graft at the face, neck, hands, feet, or genitalia. It is used when the treated wound area reaches the large-area threshold for this anatomic group, after the initial area is reported with the primary service. Surgeons and clinicians who provide specialized wound care may perform the application for wounds such as chronic ulcers or other defects requiring graft coverage.

Choose the code based on the total wound surface area treated and the anatomic site, not the number of graft pieces used. The record should identify the wound location, dimensions or calculated surface area, and the area receiving the graft. Report this code only with its primary procedure, 15277, for each additional 100 cm² or part thereof. CMS pays it within the primary 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.

15278 billing questions

When is 15278 reported instead of 15276?

Use 15278 for additional area after the large-area primary service, 15277, at the face, neck, hands, feet, or genitalia. Code 15276 is for additional area in the smaller-area service group.

Which primary code must accompany 15278?

Report 15278 only with 15277. It accounts for additional treated area beyond the initial area represented by that primary service.

How is the number of units determined?

Base units on the additional wound surface area treated: each 100 cm² or part thereof supports an additional unit. Document the treated area rather than counting graft pieces.

What documentation supports 15278?

Document the anatomic site, wound measurements or calculated surface area, and the area actually treated with the graft. The record should support that the primary large-area service and additional area were performed.

How does CMS treat payment for this add-on?

CMS pays 15278 within the global period of its primary procedure. It is not reported as a stand-alone service.

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.
