What Q4339 covers
Q4339 identifies the Artacent Vericlen product used as a wound covering. It reports the product quantity by square centimeter, not the clinician’s work to prepare the wound or apply the material. Clinicians who perform wound procedures, including wound-care specialists and surgeons, may use it in outpatient wound clinics or surgical settings when this product is applied to a wound.
Report Q4339 with the primary procedure for the wound application; it is not submitted by itself. Record the product name, wound site, area represented by the units, and the associated application procedure. CMS treats Q4339 as an add-on paid within the primary procedure’s global period. CMS also classifies it as technical-component-only, with interpretation covered by a separate code.
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.
