Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What Q4124 covers

Q4124 identifies the Oasis tri-layer wound matrix, a porcine small-intestinal-submucosa product applied to a prepared wound bed. Wound care clinicians, surgeons, and podiatrists may use it for wounds such as diabetic foot ulcers or venous leg ulcers when a matrix is selected as part of treatment. The product is generally supplied and applied in outpatient wound clinics, physician offices, or hospital outpatient departments.

Report the product code with the primary skin-substitute application procedure, using the product’s billed unit of measure, per square centimeter. Documentation should identify the Oasis tri-layer product, wound site, amount applied, and the associated application procedure. CMS classifies Q4124 as an add-on code: it is billed only with a primary procedure, and payment falls within that procedure’s global period. It is also technical-component-only; a separate code covers interpretation. Q4124 represents the product, not the clinician’s wound assessment or the application service.
