What 20526 covers
A clinician injects medication, commonly a corticosteroid, into the carpal tunnel to treat symptoms such as pain, tingling, or numbness associated with median nerve compression. The service is typically performed by a physician or other qualified practitioner in an office or outpatient facility. The injection targets the carpal tunnel; it is not an injection into a tendon sheath or a surgical release of the tunnel.
Report the code for the treated wrist and document the indication, side, and injection performed. For treatment of both wrists, modifier 50 is paid at 150% under the CMS bilateral rule. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. The 0-day global period includes same-day preoperative and postoperative care. CMS does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
