What Q4273 covers

Q4273 identifies the Esano AAA product supplied for wound coverage, measured in square centimeters. It represents the product, not the clinician’s work to prepare the wound or apply the material. Wound-care clinicians and surgeons may use the product in office-based wound care or hospital settings as part of a documented wound treatment. The application procedure is reported separately.

Report the measured product area in square centimeters and identify the wound and product in the record. Q4273 is an add-on code and must be billed with a primary procedure; CMS pays it within that procedure’s global period. CMS classifies Q4273 as technical-component-only, with interpretation covered by a separate code. Do not treat the Q4273 line as the professional interpretation or as a substitute for the wound-application procedure.

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.
