HCPCS code Q4132: Wound matrix, grafix Core or GrafixPL Core2026 Medicare rate & RVUs

Medicare pays $127.26 for Q4132 nationally in the office. Local office rates run $109.31–$183.51.

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

What Q4132 covers

Q4132 identifies the Grafix Core or GrafixPL Core placental membrane product supplied for wound treatment. Clinicians such as surgeons, podiatrists, and wound-care providers may use these products during treatment of chronic or other open wounds in office, outpatient, or hospital settings. The code represents the product, not the clinician’s wound assessment or application service.

Report the product with the applicable primary wound-application procedure, using the documented product and square centimeters supplied. The record should identify the Grafix product and support the quantity reported. CMS treats Q4132 as an add-on code: it is billed with a primary procedure and paid within that procedure’s global period. CMS also identifies it as technical-component-only, with interpretation covered by a separate code.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
