What 15003 covers
This add-on reports further surgical preparation of a wound recipient site on the trunk, an arm, or a leg after the initial area has been reported. The surgeon excises open-wound tissue, burn eschar, or scar, including subcutaneous tissue, to ready the wound bed for grafting or another reconstructive treatment. Plastic, burn, and other surgeons commonly perform this work in an operating room or procedure facility.
Report 15003 for each additional 100 square centimeters, or each additional 1% of body surface area in infants and children, beyond the initial area represented by 15002. The operative record should identify the treated body site, the excised tissue, and the total recipient-site area prepared. CMS classifies 15003 as an add-on: it must be billed with its primary procedure, 15002, and is paid within that procedure’s global period.

15003 billing questions
When is 15003 reported instead of 15002?
15002 represents the initial qualifying area on the trunk, arms, or legs. Report 15003 for each additional 100 square centimeters, or each additional 1% of body surface area in infants and children.
Can 15003 be billed by itself?
No. It is an add-on code and must be reported with 15002 for the initial area.
Does wound-bed preparation include the graft placement?
No. The preparation describes excision to ready the recipient site; graft or other reconstructive treatment is a separate service when performed and reportable.
What documentation supports additional units?
Document the anatomic site, the tissue excised, and the total recipient-site area prepared. The recorded area should support each additional 100-square-centimeter increment or, for an infant or child, each additional 1% body-surface-area increment.
How does the global-period rule affect 15003?
CMS treats 15003 as an add-on paid within the primary procedure’s global period. It is not reported as a standalone service.
