What Q4326 covers
Q4326 identifies WoundPlus supplied for wound coverage during a wound-care procedure. It represents the product, not the clinician’s work applying it. Wound specialists, podiatrists, surgeons, and other clinicians may use wound coverage products when treating ulcers or other wounds in outpatient settings. The specific product and the amount used should be identifiable in the record and supported by the product documentation.
Report the quantity in square centimeters and pair Q4326 with the primary procedure for the wound service; the application procedure is reported separately. CMS classifies Q4326 as an add-on, with payment within the primary procedure’s global period. CMS also identifies it as technical-component-only, with interpretation covered by a separate code. Documentation should connect the WoundPlus product to the treated wound and state the quantity used. The product code does not replace the code describing the application service.
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.

Q4326 billing questions
When should Q4326 be chosen instead of another wound-product code?
Use Q4326 when the product supplied is WoundPlus. Other Q codes identify different products, even when they are also measured by square centimeter.
Is the wound application included in Q4326?
No. Q4326 identifies the WoundPlus product; report the applicable wound application procedure separately.
Can Q4326 be submitted by itself?
No. CMS classifies it as an add-on code that must be reported with a primary procedure.
What quantity should be documented?
Document the square-centimeter quantity of WoundPlus used and identify the treated wound. The code is measured per square centimeter.
Does Q4326 include a professional interpretation?
No. CMS identifies Q4326 as technical-component-only and indicates that a separate code covers interpretation.
