Article Overview

This premium coding article explains how to review an operative report for a lumbar facet cyst excision case and determine the appropriate CPT assignment when the procedure documentation does not explicitly describe a laminectomy. It is aimed at coders, billers, and CDI or audit professionals working with spine surgery records, and it focuses on interpreting operative wording, procedure scope, and related anatomic terminology in the context of CPT reporting.
