What Q4250 covers
Q4250 identifies the AmnioAMP-MP amniotic membrane product by the square centimeter. It represents the product supplied for wound coverage, not the clinician’s work applying it. Wound care clinicians, surgeons, and podiatrists may use this type of membrane during treatment of wounds in office, outpatient, or surgical settings. The product code is reported with the primary procedure that applies the membrane, such as an appropriate skin substitute application service.
Report units according to the square centimeters of product supplied, supported by the product record and documentation of the wound site, dimensions, and amount used. Q4250 is an add-on code: bill it only with a primary procedure, and payment falls within that procedure’s global period. It is a technical-component-only code; a separate code covers interpretation. The application service and the product are distinct coding elements, so the application procedure must be reported separately when performed.

Q4250 billing questions
Can Q4250 be billed by itself?

The unit of measure is one square centimeter. Document the product amount supplied and the wound dimensions that support the reported units.
Does Q4250 include the clinician’s application work?
No. Q4250 identifies the AmnioAMP-MP product; report the applicable primary procedure separately for the work of applying it.
Is interpretation included in Q4250?
No. CMS identifies Q4250 as technical-component-only, with interpretation covered by a separate code.
How does Q4250 differ from Q4247?
