PICA embolization

Date: Mar 3, 2023

Question:

We have an embolization involving the posterior inferior cerebellar artery. It was originally coded with 61626; however, the provider and I feel it should be 61624 since it is intracranial. The coder is citing the definition of intracranial as the vessel needs to branch from internals or directly from spine. I am somewhat new to this and would like clarification.
