What Q4361 covers
Q4361 identifies Epixpress wound-covering material supplied by square centimeter for placement over a wound during a skin-substitute application. It reports the product supply, not a separate debridement or wound-preparation service. Wound-care clinicians and surgeons may use it in outpatient wound clinics, offices, or hospital departments when the treatment plan calls for this material.
Report the quantity in square-centimeter units and identify the product, wound site, treated area, and corresponding application procedure in the record. CMS classifies Q4361 as an add-on, so it is billed only with a primary procedure and paid within that procedure’s global period. The code represents the technical component only; a separate code covers interpretation. Select the primary application procedure according to the wound’s site and area.
