Cerebral angiography
About 36228: Selective intracranial branch catheterization
Reports selective catheter placement and angiography of an additional intracranial branch, such as an anterior or middle cerebral artery branch, during cerebral angiography.
This add-on describes selective catheterization of an additional second- or third-order intracranial branch within a vascular family, with angiography of the selected vessel and its supplied intracranial branches when performed. Neurointerventional physicians and other physicians performing diagnostic cerebral angiography may use it when they advance the catheter beyond an internal carotid or vertebral artery into a qualifying intracranial branch. The service is commonly performed in a hospital angiography suite.
Report 36228 with the applicable primary angiography service, commonly 36224 for an internal carotid artery study or 36226 for a vertebral artery study; it is not reported alone. Documentation should identify the vascular family, the additional branch selectively catheterized, and the angiography performed. Report the code for each qualifying additional branch. It is an add-on paid within the primary procedure's global period. For a bilateral procedure reported with modifier 50, CMS pays 150% of the single-procedure amount.

36228 billing questions
When is 36228 reported instead of 36224 or 36226?
Use 36224 or 36226 for the applicable internal carotid or vertebral artery angiography service. Add 36228 when the catheter is selectively advanced into an additional qualifying intracranial branch within that vascular family.
Can 36228 be billed by itself?
No. It is an add-on code and must be reported with the applicable primary procedure, commonly 36224 or 36226.
How many units of 36228 should be reported?
Report a unit for each qualifying additional second- or third-order intracranial branch selectively catheterized. The record should identify each branch and the angiography performed.
What supports reporting 36228?
Document the parent vascular family, the specific additional intracranial branch entered selectively, and the imaging performed. Imaging branches from a catheter that remains in the internal carotid or vertebral artery alone does not establish this additional selective catheterization.
How is bilateral 36228 handled?
For a bilateral procedure reported with modifier 50, CMS pays 150% of the single-procedure amount. The add-on must still be reported with its applicable primary procedure.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
