What is CPT Code 20550?

CPT 20550 is defined as: The injection of a therapeutic agent (typically a corticosteroid and/or local anesthetic) into a single tendon sheath, ligament, or aponeurosis (such as the plantar fascia). This procedure is performed to reduce inflammation and alleviate pain associated with conditions like tenosynovitis, trigger finger, or plantar fasciitis. It does not include the use of imaging guidance, which must be billed separately or using a different code if bundled.

This code is primarily used for Specialist services. It falls under the category of Surgery / Musculoskeletal System and is valid for the 2026 calendar year according to the CMS Physician Fee Schedule.
