What Q4275 covers
Q4275 identifies the Esano ACA wound product by area; it does not describe the clinician’s wound assessment or the application procedure. Wound care physicians, podiatrists, surgeons, and other clinicians may use it in outpatient wound care, including treatment of chronic wounds such as diabetic foot ulcers or venous leg ulcers. The product is placed on a prepared wound as part of the treatment plan.
Report the product only with a primary procedure, and document the product variant and square-centimeter quantity used so the claim can be reconciled with the clinical record and product packaging. CMS identifies Q4275 as an add-on code, with payment within the primary procedure’s global period. CMS also classifies it as technical-component-only, with interpretation covered by a separate code; Q4275 does not represent a professional interpretation.

Q4275 billing questions
How is Q4275 distinguished from Q4274?
Q4275 identifies Esano ACA, while Q4274 identifies Esano AC. Select the code matching the specific product furnished, not the wound site or severity.
Can Q4275 be billed by itself?
No. CMS designates it as an add-on code, so it is reported with a primary procedure rather than as a standalone service.
What supports the units reported?
Document the Esano ACA product used and its square-centimeter quantity. The record should support the billed amount and connect it to the treated wound and primary procedure.
Does Q4275 include the wound application procedure?
No. Q4275 identifies the product quantity; report the appropriate primary procedure separately when performed.
How does the technical-component designation affect reporting?
CMS classifies Q4275 as technical-component-only and indicates that interpretation is covered by a separate code. Q4275 itself does not represent a professional interpretation.
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.
