HCPCS code A2028: Micromatrix Flex, per milligram2026 Medicare rate & RVUs

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

What A2028 covers

A2028 identifies Micromatrix Flex as an item reported by milligram. The unit basis is mass, not surface area or a count of sheets. Report the quantity of Micromatrix Flex furnished in milligrams; the named product determines whether A2028 applies rather than another code for a different product. The code is designated technical-component-only, with interpretation covered by a separate code.

Medicare assigns A2028 carrier-priced physician fee schedule status (status C): CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The HCPCS pricing method is contractor pricing under the physician fee schedule. Coverage is left to the contractor's judgment. Report units according to the milligrams furnished, with product and quantity documentation supporting the claim.

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.
