What Q4235 covers
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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
