Summary

When submitting prior authorization requests to Telligen for therapy services, providers must include the appropriate modifier (GN, GO, or GP) on the PA that exactly matches the modifier used when billing the claim. This prevents claim denials for duplicate services.

Action Required

Action needed

Immediately: Billing team must ensure all therapy prior authorization requests to Telligen include the exact modifier that will be used on the claim (GN for speech therapy, GO for occupational therapy, GP for physical therapy). Update PA request process to verify modifier consistency. Claims will be denied if PA and claim modifiers don't match exactly.
