About Q4348: Sentry SL wound matrix supply
Reports Sentry SL matrix supplied for wound treatment, measured by area and billed alongside the primary procedure that applies the matrix.
Q4348 identifies Sentry SL matrix supplied by area for wound treatment. A wound-care physician, surgeon, podiatrist, or other qualified clinician may apply the matrix to a prepared wound in an office or outpatient procedural setting. This code represents the named product, not the clinician’s wound assessment or the application service. The record should identify the treated wound and the area of Sentry SL matrix used.
Report Q4348 only with the applicable primary procedure; CMS treats it as an add-on paid within that procedure’s global period. Submit the quantity in square centimeters and retain documentation linking the product and amount to the wound treated. CMS classifies the code as technical-component-only, with interpretation covered by a separate code. The application procedure and product supply are distinct reporting elements, so the record should support both the primary service and the product quantity.

Q4348 billing questions
How is Q4348 different from another wound matrix code?
Q4348 identifies Sentry SL specifically. Select the product code that matches the matrix actually supplied and used; nearby matrix codes identify different products.
Can Q4348 be reported by itself?
No. CMS identifies it as an add-on that must be billed with the applicable primary procedure, and payment falls within that procedure’s global period.
How should the quantity be reported?
Use the square-centimeter quantity supported by the amount of Sentry SL matrix used. Document the wound and area treated.
Does Q4348 include the wound application service?
No. Q4348 identifies the matrix product; report the applicable primary procedure for the service that applies it.
How does the technical-component rule affect billing?
CMS classifies Q4348 as technical-component-only. A separate code covers interpretation.
