Oklahoma law (HB 3350, 2022) requires health insurers to respond to standard prior authorization requests within 3 business days and urgent/expedited requests within 1 business day. Denial notices must include specific clinical criteria, reviewer credentials, and appeal instructions. Oklahoma also prohibits insurers from retroactively denying preauthorized services.
Overview
Prior authorization is a pre-service approval process used by insurers to determine whether a planned treatment meets medical necessity and coverage standards. Oklahoma HB 3350 (2022) strengthened prior authorization rules by establishing fast response timelines, requiring detailed denial notices, and prohibiting retroactive denials. These reforms accelerate treatment approvals and protect patients from unexpected billing for preauthorized services.
Emergency services are exempt from prior authorization requirements, though insurers may conduct retrospective review after the fact.
Key Requirements
- Standard PA response: 3 business days from receipt of a complete PA request.
- Urgent/expedited PA response: 1 business day from receipt of a complete urgent PA request.
- Emergency services: Prior authorization not required.
- Denial notice requirements: Denials must include specific clinical criteria, clinical reviewer qualifications, and full appeal instructions.
- No retroactive denial: Insurers cannot retroactively deny claims for services that were preauthorized in good faith.

Penalties and Enforcement
The Oklahoma Insurance Department enforces HB 3350 through administrative penalties and market conduct examinations. Violations include:
- Civil penalties for failure to respond within required timelines.
- Penalties for retroactively denying preauthorized services.
- Requirement to reconsider denials with proper documentation.

Appeals and Dispute Resolution
When an insurer denies a PA request:
- Internal appeal: Providers have 180 days from denial to file an internal appeal.
- External review: If internal appeal is denied, providers can request an external independent review from the Oklahoma Insurance Department.
- OID complaint: If the insurer fails to respond within required timelines, does not provide adequate denial notice, or retroactively denies a preauthorized service, file a complaint with the Oklahoma Insurance Department.
Federal Law and Coordination
Federal CMS-0057-F rule (effective 2026) requires Medicare Advantage plans to accept electronic PA submissions. Oklahoma's state law PA response timeline (3 business days for standard, 1 business day for urgent) is among the fastest in the nation, providing strong provider protection. ERISA plan PA requirements follow federal rules unless Oklahoma law is more favorable to providers.
