What Q4309 covers
Q4309 identifies Via Matrix by the area supplied, in square centimeters, for wound treatment. It represents the product rather than the clinician’s wound assessment or the work of applying a graft. Wound care clinicians may use it in outpatient treatment of a wound when Via Matrix is the product selected and the applicable wound procedure is performed.
Report Q4309 only with a primary procedure; CMS treats it as an add-on and places its payment within that procedure’s global period. Select the primary application code according to the treated site and wound area, and document the product used and the area supplied so the reported units can be supported. CMS classifies Q4309 as technical-component-only, with interpretation covered by a separate code. Its physician work RVU is zero; the code accounts for the technical component.
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.

Q4309 billing questions
Can Q4309 be billed by itself?
No. CMS identifies Q4309 as an add-on code that must be reported with a primary procedure.
Which application code should accompany Q4309?
Choose the primary skin-substitute application code based on the treated site and wound area. For example, 15271 and 15273 apply to different site groups.
How are Q4309 units counted?
The code is measured per square centimeter. Document the Via Matrix product and the area supplied to support the units reported.
Does Q4309 include the work of applying the product?
Q4309 identifies the product, not the clinician’s application work. Report the appropriate primary application procedure with it.
How does CMS classify the code’s components?
CMS classifies Q4309 as technical-component-only; interpretation is covered by a separate code. The code has zero physician work RVUs.
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.
