Pre-authorization requirements

Pre-authorization requirements are insurer-mandated conditions that require healthcare providers to secure approval before delivering specific procedures, medications, or services. Insurers such as UnitedHealthcare and Aetna designate hundreds of treatments–including MRIs and elective surgeries–for pre-authorization due to cost control.

Physicians submit clinical documentation, including diagnosis codes and treatment plans, to insurers for review. Insurers notify providers of approvals or denials typically within 72 hours for non-emergencies, as reported by the Insurance Information Database.

Medicare Part B enforces pre-authorization for certain durable medical equipment like power wheelchairs. If you skip pre-authorization for listed services, insurers routinely deny payment, leaving patients financially responsible–examples: out-of-network hospital admissions or advanced imaging scans.

Emergency services often bypass pre-authorization; only 14% of ER claims underwent such reviews in 2022 (Kaiser Family Foundation). Health plans specify all required services on member policy documents or provider portals, such as the Blue Cross Blue Shield prior authorization list.

Appeals processes exist: In 2023, 23% of denied authorizations were overturned after patient-provider appeals (AHIP survey). Pre-authorization does not guarantee full payment but signals provisional coverage pending further claim review.

Insurers use analytics software to flag new drugs or devices for future pre-authorization based on annual cost trends above $10,000 per patient (Express Scripts).
