About Q4338: Artacent Velos wound product
Q4338 reports Artacent Velos wound-covering product by square centimeter when supplied for placement during a skin-substitute application procedure.
Q4338 identifies the Artacent Velos product used as a wound covering; it is a supply code, not the clinician’s application service. Wound-care clinicians, surgeons, and podiatrists may use the product in outpatient wound-care settings. The related application procedure is selected separately according to the treated site and wound area.
Report units by the square centimeters of product used, and document the product, wound site, and quantity. Q4338 is an add-on code: submit it with a primary procedure, not by itself, and its payment falls within that procedure’s global period. CMS classifies it as technical-component-only, with interpretation covered by a separate code. The code represents the product rather than physician work.
CMS billing rules for Q4338
- Global period
- Add-on code: billed only together with a primary procedure and paid within that procedure's global period.

Q4338 billing questions
Can Q4338 be billed by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure; payment is within that procedure’s global period.
Does Q4338 include the wound application?
No. Q4338 identifies the Artacent Velos product. Report the appropriate application procedure separately for the service performed.
How are units determined?
The code is reported per square centimeter. Document the quantity of Artacent Velos used for the wound.
How do I distinguish Q4338 from Q4337 or Q4339?
Each code identifies a different named product. Report Q4338 when the product used is Artacent Velos, rather than Artacent Trident or Artacent Vericlen.
