What 36216 covers

A physician advances a catheter through an arterial route into a second-order branch in the thoracic or brachiocephalic arterial distribution. This selective positioning may support angiography or an endovascular procedure, commonly in a hospital catheterization or angiography suite. Interventional radiologists, vascular surgeons, and other physicians performing catheter-based vascular services may report the placement when the documented catheter path reaches this branch level.

Choose the code from the vessel hierarchy and the catheter tip’s destination, not from the number of imaging runs or the clinical diagnosis. The record should identify the access route, vessels traversed, target branch, and related imaging or intervention. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, CMS pays the highest-valued procedure in full and reduces others under its standard multiple procedure rule. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery billing 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.

36216 billing questions

How does 36216 differ from 36215 and 36217?

Select by catheter destination within the arterial tree: 36215 represents a first-order branch, 36216 a second-order branch, and 36217 a third-order or more selective branch.

Can 36216 be reported for each additional branch selected?

Use 36216 for the qualifying second-order placement. For each additional second-order or more selective branch in the same vascular family, consider add-on code 36218 when its reporting criteria are met.

What documentation supports 36216?

Document the access route, the vessels traversed, the target branch and its order, and the diagnostic or therapeutic service associated with the catheter placement.

Should 36216 be reported with cervicocerebral angiography codes?

Codes such as 36222 describe cervicocerebral angiography services that include catheter placement. Do not separately add 36216 for catheter work already represented by that service.

Can modifier 50 or an assistant-at-surgery modifier be used?

Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

How does CMS reduce payment when other procedures are performed in the session?

The highest-valued procedure is paid in full, and other procedures subject to the standard multiple procedure rule are paid at 50%.

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.
