What Q4306 covers
Q4306 reports the American Amnion AC amniotic membrane product used as a wound-covering material. It represents the product supply measured by area, rather than the clinician’s work to prepare and place the material. Wound-care clinicians, including physicians and other qualified practitioners, may use it during skin-substitute treatment of a wound in an office or facility setting.
Report the square-centimeter quantity supported by the product and wound documentation, and pair the code with the primary procedure for the application. The record should identify the product, treated wound site, amount used, and application service. Q4306 is an add-on code and is paid within the primary procedure’s global period. It is technical-component-only; a separate code covers interpretation.
