About Q4359: Choriply wound matrix supply
Reports the square centimeters of Choriply furnished for wound treatment, alongside the primary wound procedure that applies the placental-derived matrix.
Q4359 identifies the Choriply placental-derived wound matrix supplied for wound treatment; it represents the product, not the clinician’s work to prepare or apply it. Clinicians may use a wound matrix as part of care for a wound such as a chronic ulcer. The treating practitioner documents the wound and performs the associated application procedure in an office, hospital outpatient department, or other appropriate care setting.
Report the product in square-centimeter units and pair it with the applicable primary application procedure; the product code cannot stand alone. Documentation should identify Choriply, the treated wound, the amount supplied or applied in square centimeters, and the related procedure. CMS classifies Q4359 as an add-on paid within the primary procedure’s global period. CMS also classifies it as technical-component-only, with interpretation covered by a separate code when applicable; Q4359 represents the product rather than a professional interpretation.

Q4359 billing questions
Should Q4359 be reported instead of the wound application procedure?
No. Q4359 reports the Choriply product and must be billed with a primary application procedure, such as an appropriate wound application code.
How should the units be counted?
Report the square centimeters of Choriply represented by the claim. Document the product and the quantity in square centimeters.
Can Q4359 be billed by itself?
No. CMS identifies it as an add-on code that is billed with a primary procedure and paid within that procedure’s global period.
Does Q4359 include the clinician’s work to apply Choriply?
No. Q4359 identifies the product. Report the applicable primary procedure for the wound application.
How does Q4359 differ from Q4360?
Q4359 identifies Choriply, while Q4360 identifies Amchoplast FD. They are separate product codes, not interchangeable codes for the same product.
