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.

Q4132 billing questions

Can Q4132 be billed by itself?

No. CMS identifies it as an add-on code, so report it with the applicable primary wound-application procedure.

How should the quantity be reported?

Q4132 is reported per square centimeter. Keep documentation of the Grafix product and the quantity supplied to support the units.

Is Q4132 the wound-application service?

No. It identifies the Grafix Core or GrafixPL Core product; the wound-application service is reported separately with the appropriate primary procedure.

How does Q4132 differ from Q4133?

Q4132 identifies Grafix Core or GrafixPL Core. Q4133 identifies other named products in the Grafix and Stravix family, so select based on the product actually supplied.

Does Q4132 include interpretation?

CMS classifies Q4132 as technical-component-only and states that a separate code covers interpretation.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
