What Q4353 covers

Q4353 identifies Xceed TL Matrix by the square centimeter for use as a wound matrix in wound treatment. Wound care clinicians and surgeons may use the product to cover a prepared wound bed, including wounds managed in outpatient wound clinics or surgical settings. The code identifies the product quantity, not the clinical service of preparing the wound or applying the matrix.

Report Q4353 only with a primary procedure; CMS treats it as an add-on code, with payment within that procedure’s global period. Document the product used and the square-centimeter quantity represented by the claim, along with the wound and treatment details supporting the primary procedure. CMS classifies this as a technical-component-only code, with a separate code covering interpretation.

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.

How to choose

Q4351Wound matrix
Q4351 identifies Enclose TL Matrix; use Q4353 for Xceed TL Matrix. Both are product-specific codes measured by square centimeter.
Q4352Wound matrix
Q4352 identifies Overlay SL Matrix rather than Xceed TL Matrix. Select the code matching the product furnished.
Q4343Wound matrix
Q4343 identifies Dermacyte AC Matrix, not Xceed TL Matrix. The product identity, rather than wound size alone, distinguishes these codes.

Q4353 billing questions

Can Q4353 be billed by itself?

No. CMS identifies Q4353 as an add-on code, so it must be billed with a primary procedure.

How are units determined?

The code is reported per square centimeter. Document the Xceed TL Matrix quantity represented on the claim and the treated wound area.

Is the matrix application included in Q4353?

Q4353 identifies the product quantity, while the required primary procedure represents the associated service. Do not treat the product code alone as the wound-preparation or application service.

What does the technical-component-only designation mean?

CMS classifies Q4353 as technical-component-only; a separate code covers interpretation.

What documentation supports reporting Q4353?

Record the wound treated, the Xceed TL Matrix product used, and its square-centimeter quantity, together with documentation for the primary procedure.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
