About Q4308: Sanopellis wound graft supply
Reports Sanopellis supplied for wound treatment, measured by square centimeter and billed with the primary procedure for its application.
Q4308 identifies Sanopellis supplied for wound care, such as treatment involving a chronic or nonhealing wound. The product may be used by clinicians performing wound treatment in settings where skin substitute grafts are applied. Report the product code separately from the procedure that applies it; Q4308 represents the Sanopellis supply, not the clinician’s wound preparation or application work.
Select Q4308 when Sanopellis is the product furnished, and report units based on the documented square centimeters. The record should identify the product and support the quantity supplied and used. CMS classifies Q4308 as an add-on: report it only with a primary procedure, and payment falls within that procedure’s global period. CMS also classifies it as technical-component-only, with interpretation covered by a separate code.
CMS billing rules for Q4308

Q4308 billing questions
Is Q4308 the wound application procedure?
No. Q4308 reports the Sanopellis product; report the applicable primary procedure for the clinician’s application work.
Can Q4308 be billed by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure.
How are units determined?
The code is measured per square centimeter. Document the Sanopellis product and the square-centimeter quantity supplied and used.
What does the global-period rule mean for payment?
CMS pays Q4308 within the primary procedure’s global period. Report it with the primary procedure rather than as a stand-alone service.
How does Q4308 differ from Q4307 or Q4309?
Those codes identify different products. Use Q4308 only when Sanopellis was furnished, even though the neighboring product codes also use a per-square-centimeter unit.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
