What 15273 covers

A clinician applies a skin substitute graft to a wound on the trunk, an arm, or a leg. This service is commonly performed by surgeons and wound-care clinicians for wounds such as chronic diabetic or venous ulcers and other wounds requiring graft coverage. The graft is applied to the wound; this code is not for harvesting a patient's own skin. The corresponding codes distinguish wound location and total treated surface area.

Choose this base code when the total wound area meets the large-area threshold for the trunk, arms, or legs. For infants and children, the area basis uses body surface area rather than the adult square-centimeter measure. Document wound location, measurements, the total area treated, and graft application. Code 15274 reports each additional area increment with this service. Medicare includes same-day preoperative and postoperative care in the 0-day global period. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. 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.

15273 billing questions

How does 15273 differ from 15271?

Both cover skin substitute graft application to the trunk, arms, or legs. Select between them based on the total wound surface area and the applicable adult or pediatric area measure.

When is 15274 reported with 15273?

Report 15274 for each additional area increment beyond the area covered by 15273. Document the total treated wound area to support the base and additional units.

Can modifier 50 be used for wounds on both legs?

No. CMS identifies bilateral adjustment as inappropriate for this code. Report the service based on the treated wound area and applicable coding instructions.

Is routine same-day postoperative care separately included?

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.
