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

What Q4307 covers

Q4307 represents American amnion furnished for application to a wound. It is used in wound management, including treatment of chronic ulcers, when the clinician selects this specific amnion product as a wound covering. Physicians and other qualified practitioners may apply the product in outpatient settings such as a clinic or hospital department; the associated application procedure is reported separately when supported by the service performed.

Report units based on the documented square centimeters of product supplied, and pair Q4307 with the applicable primary application procedure. The record should identify the product, wound site and size, amount used, and application performed. CMS classifies Q4307 as an add-on code, so it is billed only with a primary procedure and paid within that procedure’s global period. It is a technical-component-only code; a separate code covers interpretation.
