What Q4103 covers
Q4103 represents the Oasis biologic matrix intended for burn-wound coverage; it reports the product, not the clinician’s work to prepare the wound or place the matrix. Burn surgeons, plastic surgeons, and wound-care clinicians may use it during burn treatment in an operating room or outpatient wound-care setting. The application service is represented separately by the applicable procedure code.
Report the product with the primary procedure, using documentation that identifies the product, the treated burn site, the quantity used, and the associated application service. CMS classifies Q4103 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period. It is also a technical-component-only code; a separate code covers interpretation.
