About A2042: Foundation DRS+ Solo wound matrix, per square centimeter
Report A2042 for each square centimeter of Foundation DRS+ Solo used during a qualifying wound procedure, alongside the primary procedure code.
Foundation DRS+ Solo is a wound matrix identified by its specific product name and measured by area. A2042 captures the material used when a clinician places this product during a wound procedure, such as treatment of a wound bed. The treating clinician documents the product placed, the wound site, and the area used; the product code identifies the material rather than the clinician’s application work.
Report one unit for each square centimeter of Foundation DRS+ Solo used, supported by the treatment record and product documentation. Confirm the exact product name: Foundation DRS Solo has a different code, and Foundation DRS+ Duo is another distinct product. CMS classifies A2042 as an add-on, so report it only with the primary procedure; payment falls within that procedure’s global period. CMS also prices A2042 as a technical-component-only code, with no physician work RVUs. Interpretation, when separately performed and reportable, is represented by a separate code rather than A2042.
