What 20604 covers
An orthopedist, rheumatologist, sports medicine physician, or other qualified clinician uses ultrasound to guide a needle into a small joint or bursa for fluid removal, medication delivery, or both. Common targets include joints of the fingers or toes. The ultrasound guidance, permanent image recording, and reporting are part of the service. It may be performed in an office or facility setting.
Choose this code for a small joint or bursa, rather than an intermediate or major target; document the site, whether aspiration, injection, or both occurred, and the ultrasound guidance and saved images. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others at 50%. For bilateral services reported with modifier 50, CMS pays 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery 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.

20604 billing questions
How does this differ from 20600?
Both codes address a small joint or bursa. Report 20604 when ultrasound guidance is used and permanently recorded and reported; 20600 is the counterpart without ultrasound guidance.
Can ultrasound guidance be billed separately?
The ultrasound guidance, permanent recording, and reporting are included in 20604. Do not separately report guidance for the same aspiration or injection.
Which joint-size code applies to a wrist injection?
The wrist is an intermediate joint, not a small joint. Use the code matching the intermediate-joint service and whether ultrasound guidance was used.
What documentation supports 20604?
Document the specific small joint or bursa, the aspiration or injection performed, and ultrasound guidance with permanent image recording and reporting.
How is bilateral treatment paid?
When the bilateral procedure is reported with modifier 50, CMS pays 150%.
What happens when this is performed with another procedure?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures in the same session are paid at 50%.
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.
