Article Overview

This short coding guidance article explains how CPT guidance applies to a question about reporting a dural closure after ligation of an intracranial internal carotid artery aneurysm. It is useful for coders and billing staff working with neurosurgery, skull base procedures, and postoperative repair scenarios because it discusses when a secondary repair may be considered versus when primary closure is part of the definitive procedure. The article references CPT coding guidance and skull base surgery guidance at a high level without providing a full coding lesson.
