About Q4115: AlloSkin skin substitute product
Reports AlloSkin human skin allograft supplied for wound coverage when furnished with a primary wound-treatment procedure.
Q4115 identifies AlloSkin, a human skin allograft product supplied for wound coverage. It may be used by clinicians treating wounds that require biologic skin coverage, including chronic ulcers or surgical wounds. The surgeon, podiatrist, or wound-care clinician applies the product in an outpatient wound-care or surgical setting. This code represents the product, not the work of preparing the wound or applying the graft.
Report Q4115 for the AlloSkin product furnished, using the HCPCS unit measure of one square centimeter and documenting the product, quantity, and treated wound. Pair it with the primary wound-treatment procedure; CMS classifies it as an add-on and places payment within that procedure's global period. This is a technical-component-only code, with interpretation represented by a separate code. The documentation should identify AlloSkin specifically so it is distinguishable from other skin substitute products.
