About Q4291: Lamellas XT wound product supply
Q4291 reports the area of Lamellas XT wound product furnished with a primary procedure, billed by square centimeter rather than as the application service.
Q4291 identifies Lamellas XT wound product supplied for wound coverage, measured by area. It represents the product, not the clinician’s work to prepare or apply it. It may be reported in outpatient wound clinics, hospital outpatient departments, or other settings where a clinician performs a related wound procedure. The clinical record should identify the wound treated, the product used, and the square-centimeter quantity supported by the service.
CMS classifies Q4291 as an add-on code, so report it only with a primary procedure; its payment falls within that procedure’s global period. The code is technical-component-only, with interpretation covered by a separate code. Select Q4291 when the product furnished is Lamellas XT, rather than another wound product with its own HCPCS code. Keep the product quantity distinct from the primary procedure’s application or treatment service, and ensure the documentation supports both the primary service and the area reported.

Q4291 billing questions
When should I use Q4291 instead of Q4292?
Use Q4291 for Lamellas XT. Q4292 identifies Lamellas; the product actually furnished determines which code to report.
Can Q4291 be billed by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure, and its payment is within that procedure’s global period.
Does Q4291 include the application service?
No. Q4291 reports the Lamellas XT product by area. Report the primary procedure separately when performed and supported by the record.
How should the quantity be documented?
Document the wound treated, the Lamellas XT product used, and the square-centimeter quantity supported by the service.
Is interpretation included in Q4291?
No. CMS classifies Q4291 as technical-component-only; a separate code covers interpretation.
Does CMS specify a modifier for Q4291?
The CMS facts provided establish add-on and component status, but no Q4291-specific modifier rule. The documentation should support the product quantity and the paired primary service.
Where these rates come from
