What 36221 covers

A catheter is positioned in the thoracic aorta without selective advancement into an arch branch, and contrast images show the aortic arch and the origins of its major vessels. The service is commonly performed by an interventional radiologist, vascular surgeon, or other physician performing catheter angiography in a hospital or catheterization suite to assess arch anatomy or suspected vascular disease. The code includes the catheter placement and the radiological supervision, interpretation, image documentation, and report for the arch study.

Report 36221 when the documented catheter position and images support a nonselective arch angiogram; selective branch catheterization and the specific territory imaged point to a different cervicocerebral angiography code. The code is priced as bilateral, so modifier 50 does not increase payment. It has a 0-day global period, with same-day preoperative and postoperative care included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. 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.

36221 billing questions

When should 36221 be chosen instead of a selective carotid angiography code?

Use 36221 for nonselective catheter placement in the thoracic aorta with imaging of the arch. Selective catheterization and imaging of a carotid or other branch territory point to a selective angiography code.

Can the arch angiography interpretation be billed separately?

No. The radiological supervision and interpretation, image documentation, and report for the arch study are included in 36221.

Should modifier 50 be appended when both sides are evaluated?

The code is already priced as bilateral, and modifier 50 does not increase payment.

How does Medicare handle 36221 with other procedures in the same session?

The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple procedure reduction.

What documentation supports reporting 36221?

Document the catheter position in the thoracic aorta, the arch angiographic images obtained, and the interpretation and report. The record should support a nonselective arch study rather than selective branch catheterization.

Can an assistant surgeon or co-surgeon be reported for 36221?

Medicare does not pay an assistant at surgery for this code, and 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.
