Question:
When do we assign 36222 and do we include 36221?
Answer:
Assign code 36222 if the catheter is maneuvered into either the innominate artery or the common carotid artery with imaging of the extracranial carotid arteries. If the arch is evaluated, it is included; do not code 36221 in addition to 36222. If bilateral common carotid arteries are selected with extracranial carotid imaging bilaterally, code 36222-50.
