Insurance authorization

Insurance authorization is insurer approval for specific services before a provider delivers care. Providers submit insurance authorization requests using forms like CMS-278, including diagnosis codes and treatment plans.

Insurance companies grant or deny authorizations based on policy coverage criteria and medical necessity guidelines set by Medicare, Medicaid, or private insurers such as Aetna or UnitedHealthcare. Insurance authorization typically applies to high-cost procedures such as MRIs, chemotherapy, or elective surgeries.

Patients must obtain insurance authorizations before service dates to avoid claim denials; for example, 21% of claims lacking proper preauthorization face payment rejections (AMA, 2022). Delayed insurance authorization can postpone treatments; the AMA reports 93% of physicians experienced patient care delays due to prior authorization in 2021.

Insurers communicate insurance authorization decisions to both providers and patients via secure electronic portals or mail. Appeals for denied insurance authorizations require documentation such as peer-reviewed studies or additional clinical notes supporting medical necessity.

Most insurance authorizations expire after 30–90 days, requiring resubmission if unused within that period (e.g. Cigna: 60 days; Blue Cross: 90 days).

Emergency cases often bypass standard insurance authorization but may undergo retrospective review–such as trauma admissions or stroke interventions. Insurers monitor repeated denied authorizations from providers to flag potential overuse patterns or noncompliance with coverage policies, according to a report from https://yourinsurance.info.
