Documentation Required

- The medical record must identify the physician or non-physician practitioner responsible for and providing the care.
- The submitted medical record must support the selected diagnosis code(s) and the submitted CPT/HCPCS code must accurately describe the service performed.

- Regional or local nerve blocks performed as an adjunct to, or as the sole means of, regional/local anesthesia for an operative procedure are not affected by this noncoverage policy (i.e., such intraoperative regional/local anesthesia is allowed).
