What 23350 covers

This service places contrast material into the shoulder joint so imaging can show joint structures more clearly. It is commonly performed by a radiologist or other qualified clinician in an imaging department, using imaging guidance to direct the needle. The injection supports shoulder arthrography or CT or MRI performed with intra-articular contrast; it is not the same service as a therapeutic shoulder injection.

Report 23350 for the contrast injection, and report the imaging examination separately when performed. Documentation should identify the shoulder and side, the diagnostic purpose, and the contrast administration. For bilateral procedures, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to a 50% reduction. The 0-day global period includes same-day preoperative and postoperative care. Medicare does not pay an assistant at surgery for this code; 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.

23350 billing questions

How is 23350 different from a therapeutic shoulder injection?

Use 23350 when contrast is injected into the shoulder joint for diagnostic imaging. A therapeutic injection or aspiration of a major joint is reported with a different code, such as 20610, when that service is performed.

Is the imaging examination included in 23350?

No. 23350 reports the contrast injection; report the shoulder arthrography, CT, or MRI examination separately when performed.

How should bilateral shoulder injections be reported?

Report the bilateral procedure with modifier 50. CMS pays the bilateral procedure at 150%.

What documentation supports reporting 23350?

Document the shoulder and side, the diagnostic imaging purpose, and that contrast was administered into the joint. The record should distinguish this diagnostic injection from a therapeutic injection.

Does the 0-day global period include same-day care?

Yes. Same-day preoperative and postoperative care is included in the 0-day global period.

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.
