What 24220 covers

For code 24220, a clinician places contrast into the elbow joint space to outline its structures during arthrographic imaging. Radiologists and orthopedic clinicians commonly perform the injection in an imaging department or procedure setting. The resulting study may use radiographs or cross-sectional imaging to evaluate the joint. This is an imaging-preparation injection, not a therapeutic injection intended to treat elbow pain or inflammation.

Report the injection when the record supports intra-articular contrast placement for an elbow arthrogram, including the joint treated, laterality, and imaging purpose. The associated imaging service, such as elbow arthrography, is reported separately when performed and documented. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral reporting with modifier 50, CMS pays 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery payment 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.

24220 billing questions

How is 24220 different from an elbow therapeutic injection?

Use 24220 when contrast is injected into the elbow joint to support arthrographic imaging. A therapeutic injection is performed to treat symptoms rather than outline the joint for imaging.

Can the elbow imaging study be reported separately?

Yes. The imaging service, such as elbow arthrography reported with 73085, is separate from the contrast injection when that imaging service is performed and documented.

What documentation supports 24220?

Document the elbow and laterality, intra-articular contrast placement, and the arthrographic imaging purpose. The record should also support the imaging service reported with the injection.

How does CMS handle bilateral reporting?

CMS pays a bilateral procedure reported with modifier 50 at 150%. The documentation should support arthrographic injections in both elbows.

How does the multiple-procedure reduction affect payment?

When other procedures are performed in the same session, the highest-valued procedure is paid in full and the remaining procedures are paid at 50% under the standard multiple-procedure reduction.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. CMS does not permit co-surgeon or team-surgery payment for this code.

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.
