Action Required

Action needed
Before May 22, 2026: Oral and maxillofacial surgery practices in Michigan must update prior authorization processes for orthognathic surgery CPT codes to include detailed documentation requirements: clinical photographs/dental models, specific functional impairment descriptions, imaging documentation, and precise jaw discrepancy measurements (4mm+ anteroposterior discrepancies, 2+ standard deviations for skeletal deformities, 3mm+ asymmetries). Update intake forms and EMR templates to capture required measurements and functional assessments. Train staff on new measurement criteria to avoid claim denials.
