Question:

How do I bill for bilateral internal carotid angiograms (from an internal carotid catheter position) and an arch angiogram?

Answer:

The new cervicocerebral angiogram codes, both the carotid codes (36222-36224) and the vertebral codes (36225-36226), include and arch angiogram ( 36221). The only time an arch angiogram is reported is when it’s performed without one of the carotid or vertebral imaging codes.
