What A2013 covers
A2013 identifies InnovaMatrix FS, a wound matrix product used in wound treatment. It is typically furnished by clinicians treating wounds in settings such as outpatient wound clinics, physician offices, or hospital outpatient departments. The reported quantity is based on the product’s square-centimeter measure, not a weight-based unit.
Report A2013 only with a primary procedure, such as an appropriate wound application procedure selected for the wound’s site and area. Documentation should identify InnovaMatrix FS, the quantity furnished in square centimeters, and the associated primary procedure. CMS classifies A2013 as technical-component-only; a separate code covers interpretation. Payment for this add-on is within the primary procedure’s global period.

A2013 billing questions
What distinguishes A2013 from other InnovaMatrix codes?
A2013 identifies the FS product and is measured per square centimeter. Select the code matching the specific product supplied; other InnovaMatrix products have their own codes and may use different units.

A2013 is measured per square centimeter. Document the amount of InnovaMatrix FS furnished in that unit.

CMS identifies A2013 as technical-component-only, with a separate code covering interpretation. The add-on payment is included within the primary procedure’s global period.

Choose the primary application procedure according to the wound’s site and area. For example, the applicable code may be from the 15271–15278 series.
