Article Overview

This premium coding article uses a documentation challenge to review how magnetic resonance neurography should be supported in the medical record and why missing anatomic detail can make code assignment uncertain. It is aimed at coders, radiology staff, and physicians who document MRI studies involving the brachial plexus and related anatomy. The discussion also references CPT guidance, CPT Assistant, and Medicare MRI coverage policy as part of the coding context.

Why This Topic Matters

Accurate documentation determines whether the imaging service can be coded appropriately and whether the report supports the selected CPT code. The article explains why clarifying the scanned anatomy and study context matters for compliant reporting.
