About Q4437: Revival AC skin substitute per square centimeter
Reports Revival AC skin-substitute material by square centimeter when furnished with a primary wound procedure for wound coverage.
Q4437 identifies Revival AC material used as a skin substitute in wound treatment. A clinician applies the material to a prepared wound bed; wound-care physicians, podiatrists, and surgeons may furnish it in office-based or hospital outpatient wound-care settings. The code represents the product, not the clinician’s work to prepare or treat the wound.
Report the amount in square centimeters and identify the product and treated wound area in the record. CMS classifies Q4437 as an add-on code, so it must be billed with a primary procedure and is paid within that procedure’s global period. CMS also identifies it as technical-component-only, with a separate code covering interpretation; follow that component designation when reporting. The primary wound procedure and its documentation should support the application, site, and area treated.

Q4437 billing questions
Can Q4437 be billed by itself?
No. CMS classifies it as an add-on code that must be billed with a primary procedure; payment falls within that procedure’s global period.
How are units determined?
Report the Revival AC quantity by square centimeter. Document the product and the wound area treated.
Which service is the primary procedure?
Pair Q4437 with the primary wound procedure that applies the material. The correct procedure code depends on the wound site and treatment details.
Does Q4437 include interpretation?
CMS identifies Q4437 as technical-component-only and indicates that a separate code covers interpretation. Apply that component designation when reporting.
Can Q4437 be used for another skin-substitute product?
No. Q4437 identifies Revival AC; use the product-specific code that matches the material furnished.
