What 36225 covers

An interventional radiologist, neurointerventionalist, or other qualified physician selectively positions a catheter in one subclavian artery to perform angiographic assessment of the ipsilateral vertebral and/or cervical carotid vessels. This approach may be used when evaluating vertebral-origin disease or suspected subclavian steal. The service is generally performed in a hospital angiography suite or another setting equipped for catheter-based vascular imaging.

Report the code for the documented unilateral subclavian catheter position and the associated angiographic study; document the side, catheter location, vessels imaged, and findings. The specified angiographic work is represented with the catheter service. The CMS global period is 0 days, so same-day preoperative and postoperative care is included. For bilateral performance, modifier 50 is paid at 150%. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are paid at 50%. Assistant-at-surgery payment is restricted; 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.

36225 billing questions

When is 36225 used instead of 36226?

Use 36225 when the selective catheter position is in the subclavian artery. Use 36226 when the catheter is selectively positioned in the vertebral artery.

Is the angiographic study reported separately from 36225?

The code represents the subclavian catheter service with the specified ipsilateral vertebral and/or cervical carotid angiographic assessment. Do not separately report another selective catheter-placement service for the same position.

What documentation supports 36225?

Document the side, selective catheter location in the subclavian artery, vessels imaged, and angiographic findings. The record should distinguish this position from direct catheterization of the vertebral artery.

How is bilateral performance reported under the CMS rule?

For bilateral performance, report modifier 50; CMS pays the bilateral procedure at 150%.

How does the multiple-procedure reduction affect 36225?

When it is one of multiple procedures performed in the same session, CMS pays the highest-valued procedure in full and the others at 50%. The reduction depends on the relative values of the procedures performed.

Can an assistant or co-surgeon be paid for this service?

CMS does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

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.
