What 36011 covers

This code describes advancing a catheter from a larger vein into its first-order branch. For example, a catheter advanced from the inferior vena cava into a renal vein is selectively positioned in a branch; the approach route does not determine the branch order. Interventional radiologists, vascular specialists, and other physicians may perform this work in an angiography suite or another procedural setting for venography, venous sampling, or a catheter-based treatment.

Choose the code based on the catheter’s final selective position in the venous tree: a first-order branch supports 36011, while further selection into a second-order or more distal branch points to 36012. Documentation should identify the accessed venous pathway and catheter tip location. CMS applies the standard multiple-procedure reduction when multiple procedures are performed in one session: the highest-valued procedure is paid in full and the others at 50%. For a bilateral procedure reported with modifier 50, CMS pays 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.

36011 billing questions

How does 36011 differ from 36010?

36011 describes selective catheter placement in a first-order venous branch. Use 36010 when the catheter is placed in a central vein without the selective branch placement represented by 36011.

When should 36012 be used instead?

Use 36012 when the catheter is selectively advanced into a second-order or more distal venous branch. The documented catheter position, not the access site, determines the selection level.

Does 36011 include venography or image interpretation?

The code represents selective catheter placement. A venographic study or its interpretation is a distinct service; report it only when performed, documented, and separately reportable for the applicable code combination.

How is bilateral placement reported?

When the procedure is bilateral and modifier 50 is reported, CMS pays 36011 at 150%.

What happens when several procedures are performed in the same session?

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.
