[Ohio] Same‑Day Billing Limits for Per Diem Behavioral Health Services

Effective August 24, 2026, CareSource will enforce same-day billing limits for behavioral health services in Ohio. When SUD IOP/PHP group counseling (H0015, H0015TG) is billed on the same day as TBS group services (H2020, H2012), providers may bill up to one hour of additional group services without prior authorization. Any additional group services exceeding one hour on the same date of service require prior authorization, and both services require PA when limits are exceeded.
