Why Prior Authorization Varies by Insurer

Prior authorization (also called prior auth, pre-authorization, or precertification) is the process of obtaining approval from a health insurance company before a medical service is provided. Each insurer maintains its own set of prior authorization requirements, clinical criteria, submission portals, and review processes.

For healthcare providers, this means navigating different portals, documentation requirements, and timelines for every payer. A procedure that needs prior auth from UnitedHealthcare may have completely different documentation requirements than the same procedure for an Anthem BCBS member. Some payers route imaging authorizations through third-party vendors like eviCore or AIM Specialty Health, adding another layer of complexity.

Greenlight Medical eliminates this complexity by automating prior authorization across all major payers. Our platform knows each insurer's specific requirements, portal submission processes, and clinical criteria, so your staff doesn't have to.
