What 20610 covers

Code 20610 covers needle aspiration, injection, or both in a major joint or bursa, including the knee, glenohumeral joint, hip, subacromial bursa, and trochanteric bursa. A clinician may drain a knee effusion for cell count or crystal testing or inject medication into a painful joint or bursa. Orthopedists, rheumatologists, sports medicine and primary care clinicians, and advanced practice providers commonly perform it in offices. They may use palpable landmarks or separately reportable non-ultrasound imaging guidance.

Report one unit for each distinct major joint or bursa treated in a session; aspiration followed by injection of the same site remains one unit. Document the target and side, procedure performed, aspirated fluid when applicable, and injected drug and dose. Report separately payable, provider-supplied drugs with the appropriate HCPCS code and administered units. CMS assigns a 0-day global period that includes same-day preoperative and postoperative care; a significant, separately identifiable E/M requires modifier 25 on the E/M code. For multiple procedures in one session, CMS pays the highest-valued in full and others at 50%; bilateral procedures reported with modifier 50 pay at 150%. CMS does not pay an assistant at surgery or permit co-surgeons or team surgery for this code.

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.

20610 billing questions

Which joints qualify for 20610 rather than 20605 or 20600?

20610 is for major joints and bursae such as the knee, shoulder, hip, and subacromial bursa. Intermediate sites like the wrist, elbow, ankle, and olecranon bursa go to 20605, and small joints of the fingers and toes go to 20600.

If the knee is aspirated and then injected in the same session, is that two units?

No. Aspiration and injection of the same joint in one session are one unit of 20610, even if separate needle passes are needed.

How are bilateral knee injections reported to Medicare?

Report 20610 with modifier 50 on one line with one unit; CMS pays bilateral procedures at 150%. For a knee and a shoulder treated in the same session, report both sites; the multiple-procedure reduction applies, and a distinct-site modifier is used only when needed to identify separately reportable services.

Can an office visit be billed on the same day?

Yes, when the provider performs a significant, separately identifiable evaluation beyond the usual pre-injection assessment; append modifier 25 to the E/M code. The decision to inject and the brief assessment of the treated joint are included in the 0-day global.

What if imaging guidance is used?

If ultrasound guidance includes permanently recorded images and a written report, report 20611 instead of 20610; do not add 76942. For fluoroscopic needle guidance, report 20610 with the appropriate guidance code, such as 77002.

Is the injected drug included?

An eligible, provider-supplied corticosteroid or hyaluronan product may be reported separately with its HCPCS drug code and units based on the administered dose. Local anesthetic used for the procedure is not separately billed.

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.
