Y-90 arteriography

Date: Jul 23, 2021

Question:

On a first account, the patient has pre Y-90 mapping arteriography. On a second account, the patient has the Y-90 treatment with arteriography. On this second account, would the arteriography be considered guidance and not coded separately since it was just performed a few days earlier on this first account if no changes have happened in the meantime?
