About Q4235: Amniorepair or Altiply wound product
Reports Amniorepair or Altiply wound-coverage product by square centimeter when supplied with a primary wound application procedure.
Q4235 identifies Amniorepair or Altiply wound-coverage product supplied by square centimeter; it represents the product, not the work of placing it. These products may be used as biologic coverings during treatment of open wounds, including chronic ulcers. A wound-care physician, surgeon, or other qualified practitioner may apply the product to a prepared wound bed in an office or hospital outpatient setting as part of a wound procedure. The associated application service is reported separately.
Report Q4235 only with a qualifying primary application procedure. CMS classifies it as an add-on code and pays it within that procedure’s global period, so it is not a stand-alone service. Select the code based on the product supplied and report units on a per-square-centimeter basis. Documentation should identify the product, wound site, amount used, and primary procedure. CMS classifies Q4235 as technical-component-only; a separate code covers interpretation.
