About Q4102: Oasis wound matrix supply
Reports Oasis wound matrix used to cover a wound, typically alongside a skin substitute application procedure for a chronic ulcer.
Oasis wound matrix is a porcine small-intestinal-submucosa product used as a wound covering, including in treatment of chronic wounds such as diabetic foot and venous leg ulcers. A physician or other qualified clinician applies it in a wound-care setting; the product code represents the matrix, not the clinical work of preparing and applying it.
Report Q4102 only with the primary procedure for application, selecting that procedure by the treated body site and wound area. Report the matrix in units corresponding to the amount used, and document the wound, its location and dimensions, and the product applied. CMS treats this as an add-on code paid within the primary procedure’s global period. It is also designated technical-component-only, with interpretation covered by a separate code when applicable.
CMS billing rules for Q4102
- Global period
- Add-on code: billed only together with a primary procedure and paid within that procedure's global period.

Q4102 billing questions
Can Q4102 be billed by itself?
No. CMS identifies it as an add-on code, so it is reported with a primary procedure, such as the appropriate skin substitute application service.
How is Q4102 different from Q4103?
Q4102 identifies Oasis wound matrix, while Q4103 identifies Oasis burn matrix. Use the product code that matches the matrix applied.
How should the units be supported?
Document the wound dimensions, product used, and amount applied. Q4102 is reported by the area unit for the matrix.
Does Q4102 include the application work?
No. Q4102 identifies the matrix product; report the appropriate primary procedure for the application service.
What does the technical-component-only designation mean?
CMS classifies Q4102 as technical-component-only; interpretation is represented by a separate code when applicable.
