CMS' Transmittal 3523, issued May 13, is the quarterly July 1 OPPS update. In this transmittal, CMS briefly mentions billing physical and occupational therapy and speech-language pathology services provided in support of or adjunctive to comprehensive APC (C-APC) services under revenue code 0940 (general therapeutic services) rather than the National Uniform Billing Committee‑defined revenue codes for these services (i.e., 042x, 043x, and 044x, respectively).
Modifier -58 describes a staged or related procedure or service by the same provider during the postoperative period. For outpatient hospitals, the postoperative period is defined as the same service date.
