What 36012 covers

This code represents advancing a catheter from a larger vein into a more selective branch at least one level beyond a first-order branch. It may be performed by an interventional radiologist, vascular surgeon, or another physician during venous sampling, venography, or a catheter-based treatment. Adrenal vein sampling is a representative clinical situation: the operator steers the catheter into the adrenal venous branch to obtain a targeted sample.

Choose the code based on the most selective branch reached, not simply the access vein or the length of catheter advancement. The procedure report should identify the target vein and document the catheter position. This code describes catheter placement; report related imaging, sampling, or treatment services only when separately supported and permitted by applicable coding rules. When multiple procedures occur in the same session, CMS pays the highest-valued procedure in full and other procedures at 50%. For a bilateral procedure reported with modifier 50, CMS pays this code at 150%.

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.

36012 billing questions

When is 36012 used instead of 36011?

Use 36012 when the catheter reaches a second-order or more distal venous branch. Use 36011 for placement in a first-order branch.

How does 36012 differ from 36010?

36010 describes catheter placement in the vena cava. 36012 represents selective advancement from a larger vein into a more distal venous branch.

What documentation supports 36012?

The operative or procedure report should identify the target branch and show that the catheter was advanced beyond a first-order branch. Adrenal vein sampling is one example of a service where this level of selectivity may be documented.

Can venography or sampling be reported with 36012?

36012 represents catheter placement, not the imaging, interpretation, or sampling itself. Report another service only when it is separately supported and permitted by applicable coding rules.

How does CMS handle modifier 50 and multiple procedures?

For a bilateral service reported with modifier 50, CMS pays 36012 at 150%. In a session with multiple procedures, the highest-valued procedure is paid in full and the others 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.
