Injections of local anesthesia for musculoskeletal procedures (surgical or manipulative) are not separately reportable. For example, CPT codes 20526-20553 (therapeutic injection of carpal tunnel, tendon sheath, ligament, muscle trigger points) shall not be reported for the administration of local anesthesia to perform another procedure. The NCCI contains many edits based on this principle. If a procedure and a separate and distinct injection service unrelated to anesthesia for the former procedure are reported, the injection service may be reported with an NCCI-associated modifier if appropriate.
