About Q4352: Overlay SL wound matrix supply
Q4352 reports Overlay SL Matrix by square centimeter when the product is provided for wound treatment with a qualifying primary application procedure.
Overlay SL Matrix is a wound matrix product used as a covering in wound care. Q4352 identifies the product supplied, rather than the clinician’s work applying it. It may be encountered in outpatient wound clinics, podiatry practices, and surgical settings when a clinician treats a wound with a skin-substitute application procedure.
Report the product only with the required primary procedure, and calculate the quantity using the square-centimeter unit in the descriptor. Documentation should identify Overlay SL Matrix as the product used and support the quantity reported, such as through product records and the treated wound area. CMS classifies Q4352 as a technical-component-only code; a separate code covers interpretation. CMS also classifies it as an add-on code, so it is billed with a primary procedure and paid within that procedure’s global period.

Q4352 billing questions
What should be reported with Q4352?
Report it with the primary wound application procedure for which the product was used. Q4352 represents Overlay SL Matrix, not the application service.
How is the quantity determined?
The descriptor is per square centimeter. Documentation should support the amount of Overlay SL Matrix used and the wound area treated.
Can Q4352 be billed by itself?
No. CMS identifies Q4352 as an add-on code that must be billed with a primary procedure and is paid within that procedure’s global period.
Does Q4352 include interpretation?
No. CMS classifies it as technical-component-only; a separate code covers interpretation.
How is Q4352 distinguished from Q4351 or Q4353?
These codes identify different matrix products. Report Q4352 when the product used is Overlay SL Matrix, rather than selecting among them by wound size or severity.
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.
