What 20550 covers

This service delivers medication into a single tendon sheath, ligament, or aponeurosis, commonly a corticosteroid with local anesthetic. Typical targets include the flexor tendon sheath in trigger finger, the first dorsal wrist compartment in de Quervain tenosynovitis, and the plantar fascia in plantar fasciitis. Orthopedists, hand surgeons, podiatrists, rheumatologists, sports medicine clinicians, and primary care clinicians perform these injections in offices and facility settings.

Report one unit for injection(s) into one identified sheath, ligament, or aponeurosis; document each distinct target and side, technique, medication, and dose. Ultrasound needle guidance, when performed, requires separately documented guidance, retained images, and a report. Report practice-supplied medication with the appropriate HCPCS drug code and dose-based units. Medicare assigns a 0-day global period that includes routine same-day pre- and postoperative care; a separately identifiable E/M requires modifier 25. For multiple procedures in one session, the highest-valued is paid in full and others at 50%. Bilateral services with modifier 50 pay at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

20550 billing questions

Should a lateral epicondylitis injection be coded here or with 20551?

Injection at a tendon origin or insertion, such as the common extensor origin at the lateral epicondyle, is reported with 20551. Use 20550 when the target is a tendon sheath, ligament, or aponeurosis such as the plantar fascia.

How are injections of two different trigger fingers on the same hand reported?

Report each distinct tendon sheath separately and identify the injected digits. Append a distinct-site modifier when required to distinguish the services; Medicare's same-session multiple procedure reduction applies.

Can ultrasound guidance be billed with 20550?

Yes. Ultrasound needle guidance may be reported with 76942 when performed, with retained images and a separate guidance report.

Is the corticosteroid separately billable?

When the practice supplies it, report an eligible drug with its HCPCS code and documented dose-based units. For J3301, one unit represents 10 mg of triamcinolone acetonide, so 40 mg is four units.

Can an office visit be billed on the same day?

A significant, separately identifiable E/M service beyond the usual pre-injection assessment may be reported with modifier 25. The routine decision to inject is included in the 0-day global care.

When is modifier 50 appropriate?

For corresponding structures injected on both sides in one session, such as bilateral plantar fascia injections, report 20550 with modifier 50 on one line with one unit. Medicare pays the bilateral service at 150%.

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.
