What Q4349 covers

Q4349 represents the Mantle DL Matrix product used to cover a wound. Wound care clinicians, surgeons, and podiatrists may use the matrix during a procedure in an office or facility setting. The code is measured by the product area in square centimeters, rather than by the number of wounds or the clinician’s time. It identifies the specific product; it does not describe the application service itself.

Report Q4349 only with a primary procedure, such as an appropriate skin substitute application code. Documentation should identify Mantle DL Matrix and support the square centimeters furnished for the treated wound. Medicare treats Q4349 as an add-on paid within the primary procedure’s global period. It is a technical-component-only code; a separate code covers interpretation. Do not use Q4349 to represent the clinician’s interpretation of the product or procedure.

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.

Q4347 identifies Rampart DL Matrix, while Q4349 identifies Mantle DL Matrix. Choose based on the product used, not the wound’s size or site.
Q4348Wound matrix
Q4348 identifies Sentry SL Matrix rather than Mantle DL Matrix. The product name on the documentation determines which supply code applies.
Q4350Wound matrix
Q4350 identifies Palisade DM Matrix. It is not interchangeable with Q4349; report the code for the matrix actually furnished.

Q4349 billing questions

How is Q4349 different from another matrix product code?

Q4349 identifies Mantle DL Matrix specifically. Select the product code that matches the matrix actually furnished, rather than choosing by wound location or severity.

Can Q4349 be billed by itself?

No. CMS classifies it as an add-on code that must be billed with a primary procedure, such as the applicable skin substitute application service.

How many units should be reported?

The descriptor measures the product per square centimeter. Documentation should support the square centimeters of Mantle DL Matrix furnished.

Does Q4349 include the application procedure?

No. Q4349 represents the matrix product; report the primary application procedure separately when appropriate.

Does this code include interpretation?

No. CMS identifies Q4349 as technical-component-only, with a separate code covering interpretation.

How does the global period affect payment?

Medicare pays Q4349 within the global period of the primary procedure with which it is billed.

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.
