About Q4377: Trigraft skin substitute by area

Report Q4377 for Trigraft supplied for wound coverage, measured in square centimeters and billed with the applicable primary application procedure.

Q4377 identifies the Trigraft product supplied for wound coverage, with reporting based on square centimeters. A wound-care clinician, surgeon, or other treating practitioner may use the product during a wound-care encounter after preparing the wound bed. The HCPCS code identifies the product, not the clinical work of preparing the site or applying the material.

Report the quantity supported by the product used, and document the product identity, wound site, area treated, and associated application procedure. Q4377 is an add-on code: submit it only with a primary procedure, and its payment falls within that procedure’s global period. CMS classifies it as technical-component-only; a separate code covers interpretation. The applicable primary procedure depends on the wound location and treated area, so the product code does not replace the application service.

Q4377 billing questions

How is Q4377 different from another skin-substitute product code?

Q4377 identifies Trigraft specifically. Use the code matching the product actually supplied rather than choosing among product codes based only on wound size or location.

Is Q4377 reported by wound or by square centimeter?

The descriptor is per square centimeter. Document the product quantity used in square centimeters and the area treated.

Can Q4377 be billed by itself?

No. CMS identifies it as an add-on code that must be billed with a primary procedure.

Does Q4377 include the wound application service?

No. Q4377 identifies the Trigraft product. Report the applicable primary application procedure for the clinical service.

How does the global-period rule affect Q4377?

Payment for Q4377 falls within the primary procedure’s global period. Submit it with that primary procedure rather than as a standalone service.

What does the technical-component designation mean here?

CMS classifies Q4377 as technical-component-only, with interpretation covered by a separate code.
