What Q4122 covers

Q4122 represents porous DermACELL AWM, an acellular dermal matrix used in wound management. Wound-care clinicians and surgeons may use the matrix when treating wounds such as diabetic foot or venous leg ulcers. The code identifies the product, not the wound preparation or its placement.

Report the square centimeters represented by the DermACELL AWM used, and document the product, wound site, and amount. Q4122 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.

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.

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.
