Summary

Providers should reference the updated Coding Education resources on the Provider Resource Center for comprehensive coding guidance and video presentations.
Action Required
By August 22, 2026: Billing and coding staff should review the updated migraine coding guidance on Highmark's Provider Resource Center and ensure all migraine claims utilize appropriate ICD-10 codes from category G43 with proper type specification. Providers should be reminded to document specific migraine characteristics (type, aura presence, status migrainosus, etc.) to support accurate coding. Update internal coding reference materials and consider training staff on the new best practices, particularly for high-volume migraine cases. Access the Coding Education HCC University resource (authentication via Availity required) for detailed guidance and video training materials.
