Article Overview

This short CPT-focused article addresses a common coding question about an intracranial aneurysm surgery performed with microscope assistance. It explains the general reporting framework for the primary surgical service, the related add-on microscope code, and the role of CPT guidance and parenthetical notes in determining whether separate reporting is appropriate. The piece is useful for coders, billers, and reimbursement staff working with neurosurgery and CPT procedure coding.
