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.

Q4273 billing questions

Does Q4273 describe applying the product?

No. Q4273 identifies the Esano AAA product by area; report the applicable wound-application procedure separately.

Can Q4273 be billed by itself?

No. CMS identifies it as an add-on code that must be billed with a primary procedure.

How should the quantity be reported?

Report the product area in square centimeters and document the wound site and amount supplied.

How does CMS treat the global period?

Payment for Q4273 is within the global period of the primary procedure with which it is billed.

Does Q4273 include professional interpretation?

No. CMS classifies it as technical-component-only, with interpretation covered by a separate code.

How do I choose between Q4273 and another Esano code?

Use the code matching the specific Esano product supplied. Q4272, Q4274, and Q4275 identify different Esano products.

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.
