Cerebrovascular angiography

About 36227: External carotid catheterization with angiography

Reports selective catheter placement in an external carotid artery with angiography of its circulation, including intracranial imaging when performed.

A physician, commonly an interventional radiologist or neurointerventional specialist, advances a catheter selectively into an external carotid artery and performs angiography of that artery’s circulation. The study may help evaluate head and neck vascular findings, such as a suspected vascular lesion or bleeding source, and may be performed during a diagnostic or interventional angiography session. Intracranial imaging is included when performed as part of this external carotid study.

Report 36227 as an add-on with an appropriate primary cervicocerebral angiography procedure, not by itself. Documentation should identify the catheterized external carotid artery, the angiographic work performed, and the clinical findings supporting the study. CMS treats payment for this add-on as within the primary procedure’s global period. For a bilateral procedure reported with modifier 50, CMS pays 150% under the supplied fee schedule rule.
