What 36200 covers

This service covers advancing a catheter through arterial access until its tip is in the aorta, without selectively entering an aortic branch. It may be performed by an interventional radiologist, vascular surgeon, or other physician performing an aortic study. A typical use is positioning a catheter in the aorta for aortography; the documented tip location distinguishes this service from catheterization of a carotid, renal, or other branch artery.

Report the aortic placement when it is separately identifiable and not included in a more comprehensive service. Documentation should show the access route, final catheter position, and the study or procedure performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 invokes the bilateral payment rule of 150%. 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.

36200 billing questions

When should I choose 36200 instead of a selective catheterization code?

Use 36200 when the catheter remains in the aorta and no branch artery is selectively entered. If the catheter is advanced into a branch, choose the code that reflects the selective catheterization performed.

Can 36200 be reported with an aortography code?

It may be reported with a separately reportable aortographic imaging service when the catheter placement is not included in a more comprehensive code. For example, 75625 describes abdominal aortography, while 36221 includes thoracic aortic catheterization with imaging.

Is catheter placement separately reportable during an endovascular procedure?

Catheter placement that is integral to a more comprehensive intervention is not separately reported as 36200. Check whether the intervention code includes the access and catheter work.

What should the procedure note document?

The note should identify the arterial access route, the catheter's final position in the aorta, and the diagnostic study or procedure performed. It should also make clear whether a branch artery was selectively catheterized.

How does the CMS multiple-procedure rule affect 36200?

When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and applies the standard 50% reduction to the others. The 0-day global period includes same-day preoperative and postoperative care.

Can I append modifier 50 or bill an assistant surgeon?

CMS applies the bilateral rule when modifier 50 is reported, with payment at 150%. Assistant-at-surgery payment is restricted, 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.
