About Q4330: Total wound graft material
Reports Total wound graft material by square centimeter when supplied for application to a wound during a primary wound procedure.
Q4330 identifies Total, a wound graft or skin-substitute product, measured per square centimeter. A wound-care clinician, podiatrist, surgeon, or other treating practitioner may use the material on a wound bed as part of wound treatment. The product code identifies the material; it does not describe the clinical work of preparing the wound or applying the graft.
Report the number of square centimeters supported by the record, along with the primary procedure for the wound application. Documentation should identify Total as the product used and support the amount applied, such as through the treated wound’s dimensions and the amount of material used. CMS designates Q4330 as an add-on code: it must be billed with a primary procedure, and payment falls within that procedure’s global period. CMS also classifies it as technical-component-only; interpretation is represented by a separate code, not Q4330.

Q4330 billing questions
What primary service should accompany Q4330?
Report Q4330 with the primary procedure for applying the wound graft material, such as an appropriate skin-substitute application service. Q4330 identifies the Total product, not the application work.
How should the quantity be determined?
The code is measured per square centimeter. Record the amount of Total used and the treated wound area so the reported quantity is supported.
How is Q4330 different from Q4331?
Q4330 identifies Total; Q4331 identifies Axolotl graft. Select the code matching the product actually used and documented.
Is interpretation included in Q4330?
No. CMS classifies Q4330 as technical-component-only and indicates that a separate code covers interpretation.
Does Q4330 have a separate global period?
No separate period is described for Q4330. CMS treats it as an add-on paid within the primary procedure’s global period.
