What 15156 covers
This add-on covers application of additional cultured autologous skin graft to wounds on the face, scalp, neck, hands, feet, or genitalia. Burn and reconstructive surgeons commonly use cultured skin grafting to cover extensive burns or other wounds after excision, when the patient’s own skin cells have been expanded for grafting. The code represents additional wound area beyond the initial area reported with the primary service.
Report 15156 with 15155 for each additional 100 sq cm of qualifying wound area. For infants and children when area is measured by body surface area, code 15157 represents each additional 1%; do not use 15156 for that increment. Documentation should identify the graft as cultured autologous tissue, the treated anatomic sites, and the total wound surface area supporting the additional units. CMS classifies 15156 as an add-on code and 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.

15156 billing questions
When should 15156 be reported instead of 15155?
Use 15155 for the initial area and 15156 for each additional 100 sq cm at the specified sites. The add-on requires 15155 as the primary procedure.
When is 15157 used instead of 15156?
For infants and children whose wound area is reported in body-surface-area increments, 15157 represents each additional 1%. Code 15156 represents each additional 100 sq cm.
Can 15156 be billed by itself?
No. It is an add-on code reported with 15155, and CMS pays it within the primary procedure’s global period.
What area documentation supports additional units?
Document the qualifying treated sites and the total wound surface area covered with cultured autologous graft. The additional units must be supported by area beyond the initial amount reported with 15155.
How does 15156 differ from split-thickness graft code 15120?
15156 is for additional area treated with cultured autologous skin graft. Code 15120 describes a split-thickness autograft for the specified sites, rather than cultured graft application.
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.
