About Q4116: AlloDerm acellular dermal matrix
Q4116 identifies AlloDerm acellular dermal matrix used in wound coverage or soft-tissue reconstruction, reported with the related primary procedure.
AlloDerm is a human-derived acellular dermal matrix used as a tissue scaffold in wound coverage and soft-tissue reconstruction. It may be placed by surgeons or wound-care clinicians in settings such as outpatient wound treatment or reconstructive surgery. Q4116 identifies the product, not the work of preparing the site or placing the matrix; the applicable procedure is reported separately. The code is reported by square centimeter, so the documented product area—not the number of pieces alone—supports the units billed.
Select Q4116 only when the product used is AlloDerm, rather than another skin substitute or dermal matrix. The record should identify the product, the treated site, the area used, and the primary procedure. CMS classifies this as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period. It is technical-component-only; a separate code covers interpretation. CMS assigns no physician work to Q4116, with payment associated with practice expense.
