What 36226 covers

Code 36226 covers advancing a catheter directly into a vertebral artery and imaging the ipsilateral vertebral circulation in the neck and intracranially. Neurointerventional radiologists, neuroradiologists, neurosurgeons, and other physicians may perform the study in a hospital angiography suite or another appropriately equipped setting. It is used in diagnostic cerebral angiography evaluating conditions such as vertebrobasilar stenosis, arterial dissection, aneurysm, or vascular malformation. The service includes the selective catheter placement and the associated angiographic imaging of that circulation.

Report one unit for each side selectively studied, with the catheter position and imaged territory documented. A catheter left in the subclavian artery, rather than advanced directly into the vertebral artery, points to 36225 instead. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

How to choose

36225Subclavian angiography
The catheter position distinguishes the codes: 36226 requires direct vertebral artery selection, while 36225 describes selection of the subclavian artery with imaging of the ipsilateral vertebral circulation.
36224Carotid angiography
36224 is for selective internal carotid catheterization and carotid circulation imaging; 36226 is for direct vertebral selection and vertebral circulation imaging.
36221Aortic arch angiography
36221 describes arch-level angiography. It does not represent the direct selective catheter placement into a vertebral artery covered by 36226.

36226 billing questions

How do I distinguish 36226 from 36225?

Use 36226 when the catheter is selectively advanced into the vertebral artery. Use 36225 when it remains in the subclavian artery for imaging of the ipsilateral vertebral circulation.

Does 36226 include the angiographic imaging?

Yes. The code encompasses selective catheter placement and angiography of the ipsilateral vertebral artery’s cervical and intracranial circulation.

How should bilateral vertebral studies be reported?

Report the bilateral service with modifier 50 when both sides are studied. CMS pays a bilateral procedure at 150%.

What documentation supports reporting 36226?

Document the side, selective catheter position within the vertebral artery, and the cervical and intracranial territory imaged.

Can 36226 be reported with carotid angiography?

It may be part of a multivessel cerebral angiographic examination when the carotid circulation is separately selectively catheterized and imaged. Document each catheter position and the circulation studied.

Can an assistant or co-surgeon be paid for this service?

CMS applies a statutory restriction to assistant-at-surgery payment for this code. 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.
