What 20551 covers

This procedure delivers medication to one tendon origin or insertion to treat a localized condition such as tendinopathy or enthesopathy. A physician or other qualified clinician may perform it in an office or outpatient facility. A familiar example is an injection at the common extensor tendon origin for lateral epicondylitis. The target is the tendon’s attachment, not a tendon sheath or a muscle trigger point.

Report 20551 for one tendon origin or insertion; document the treated site, diagnosis, medication, and clinical rationale. The code includes the injection service, while medication may be separately reportable when applicable coding and payment requirements are met. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery services are not paid, and co-surgeon and team-surgery reporting are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

20551 billing questions

How is 20551 different from 20550?

Use 20551 when the injection targets a tendon origin or insertion. Code 20550 describes an injection into a tendon sheath or ligament.

Can 20551 be used for a trigger-point injection?

No. Trigger-point injections are reported with 20552 or 20553 according to the number of muscles treated; 20551 targets a tendon attachment.

What documentation supports 20551?

Record the specific tendon origin or insertion, the condition treated, and the medication administered. The note should make clear that the target was the attachment rather than a tendon sheath or trigger point.

How should multiple injections at the same tendon attachment be counted?

The code describes treatment of one tendon origin or insertion, not the number of needle passes or medication aliquots. Document each distinct treated target and follow applicable unit-reporting requirements.

Can modifier 50 be reported for bilateral tendon injections?

Modifier 50 is inappropriate for 20551 under the CMS descriptor and anatomy rule. Follow applicable reporting requirements for separately documented sides.

How does CMS handle same-session procedures and assistants?

When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Assistant-at-surgery services are not paid; co-surgeon and team-surgery reporting are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
