Embolization of Superior Hypophyseal Aneurysm Using Stent-Assisted Coil
A 58-year-old female presented with right superior hypophyseal aneurysm and was taken to interventional radiology for stent assisted coil embolization of the aneurysm. Provider documentation states that a catheter was used to deploy a stent in the supraclinoid internal carotid artery across the neck of the aneurysm, and then coils were introduced through the catheter into the aneurysm. What is the correct code for the embolization? Is a separate code assigned for the stent? ...

Article Overview
This premium article reviews a neurointerventional coding scenario involving aneurysm treatment in the intracranial circulation and explains the relevant ICD-10-PCS assignment considerations. It is aimed at coders, CDI professionals, and revenue cycle staff who work with interventional radiology, neuroradiology, and inpatient procedure coding. The article focuses on how the procedure is characterized in documentation, whether the stent is coded separately, and which broad ICD-10-PCS concepts apply to the case.
Why This Topic Matters
Procedure coding for neurovascular embolization can be documentation-sensitive and may affect accurate code selection, reporting consistency, and claim integrity. Understanding how the procedure is represented in ICD-10-PCS helps ensure the coded record matches the operative intent and anatomy described in the note.
