What 36251 covers

An interventional radiologist, vascular surgeon, or interventional cardiologist selectively advances a catheter into the main renal artery and any accessory renal arteries on one side to obtain renal angiographic images. The service may help evaluate suspected renal artery narrowing or define anatomy during a renal artery intervention, typically in an angiography or catheterization suite. The code includes the imaging guidance and roadmapping needed for the renal angiography; it is not limited to catheter placement alone.

Report one unilateral service when the main renal artery and any accessory arteries on that side are evaluated. Use the branch-level renal code when catheterization extends to segmental or subsegmental branches, and the bilateral code when both kidneys are treated. The record should identify the side, catheterized vessels, and angiographic work performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. In a session with multiple procedures, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and 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.

36251 billing questions

When should I report this instead of 36252?

Report this code for renal angiography on one side. Use 36252 when the service is bilateral; do not use modifier 50 to make this code bilateral.

Does this code include the angiographic imaging?

Yes. The renal angiographic imaging, intraprocedural roadmapping, and imaging guidance needed to complete the service are included.

How does 36251 differ from 36253?

This code covers the main renal artery and any accessory renal arteries on one side. Use 36253 when catheterization extends into segmental or subsegmental renal artery branches.

What documentation supports reporting this service?

Document the side, the renal arteries selectively catheterized, and the angiographic imaging performed. The report should make clear whether work was limited to the main and accessory arteries or extended into branch vessels.

How does the multiple-procedure rule affect payment?

When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%. Same-day preoperative and postoperative care is included in this code’s 0-day global period.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is restricted for this service. CMS does not permit co-surgeons or team surgery.

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.
