HCPCS Q4180: Wound productMedicare rate & RVUs

Medicare pays $127.26 for Q4180 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 Q4180 covers

Q4180 identifies Revita, a wound product measured by the square centimeter. Wound-care clinicians and surgeons may use it during a procedure that applies a skin substitute to a wound, including a lower-extremity wound. The product code reports the material; it does not replace the procedure code for applying it. The application code depends on the wound site and other applicable criteria.

Report units based on the Revita quantity furnished, with documentation supporting the product used and its measured amount. Pair Q4180 with the primary application procedure; CMS identifies it as an add-on and places its payment within that procedure’s global period. CMS also classifies Q4180 as technical-component-only, with interpretation covered by a separate code. Keep the product supply distinct from the clinician’s application service when coding the encounter.

Q4180 compared with similar codes

How to choose

Q4186EpiFix material

Q4186 identifies EpiFix rather than Revita. Select the code for the product furnished; the shared square-centimeter unit does not make the codes interchangeable.

Q4187Wound product

Q4187 identifies EpiCord rather than Revita. Use Q4180 only when the documented product is Revita.

Q4179Wound product

Q4179 identifies FlowerDerm rather than Revita. Both descriptors use a square-centimeter measure, but the product identity determines the code.

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.
