US health insurers are advancing toward real-time prior authorization decisions by 2027 after reducing request volumes by 11%, eliminating 6.5 million transactions in 10 months.
Insurers are working to deliver prior authorization determinations at the point of care through expanded use of electronic systems, with a 2027 deadline set for implementation. The effort includes standardizing data and submission requirements and targeting the ability to process about 80% of electronic prior authorization requests in real time. The transition involves operational and technical changes and requires coordination with healthcare providers.
The decline in prior authorization use follows a June 2025 commitment by more than 40 insurers to streamline approval processes. The reduction spans Medicare Advantage and certain commercial plans, removing 6.5 million authorization requests across a range of medical services, according to a Best Wire report.
Participating insurers also committed to simplifying processes for policyholders and reducing administrative demands on providers, while improving clarity in explanations of authorization decisions.
Prior authorization use among Medicare Advantage enrollees declined by more than 15%, according to industry data. The segment has drawn attention due to differences in utilization management practices compared with traditional Medicare, where prior authorization is not used.
Data released under a 2024 federal policy show variation in how often insurers require prior authorization and how frequently requests are denied. In some cases, insurers with fewer requests deny a higher share, while others require more authorizations per member.
Across plans, appeals overturn more than half of denied requests, though only a small share of denials are formally challenged.
Insurers reduced prior authorization requirements for services with established clinical guidelines, consistent utilization patterns, and predictable outcomes. These changes focused on categories of care where usage trends are stable and clinical value is well defined.
Insurers agreed to honor existing prior authorizations for a 90-day transition period when a policyholder switches plans. Data-sharing processes have been implemented to allow authorization information to transfer between insurers, with the aim of avoiding disruptions in ongoing treatment.

Prior authorization remains a source of friction across the healthcare system. Survey data indicate that nearly half of insured adults have experienced delays, denials, or changes in treatment linked to prior authorization requirements. Physician groups have reported administrative strain tied to the process and its impact on care delivery.
Employer and purchaser groups have described recent changes as initial steps, while continuing to call for further reductions in administrative barriers affecting employees and their dependents.
The current reforms are voluntary and follow earlier industry efforts that drew criticism for limited follow-through. Policymakers have required insurers to release more detailed data on authorization and denial activity, though gaps remain, including limited visibility into employer-sponsored plans and prescription drug requests.
Regulators are monitoring implementation and have indicated that further action may be considered if progress does not continue.
The changes apply to insurers covering more than 250 million Americans. While the reduction in prior authorization volume represents a measurable shift, insurers continue to maintain that the process plays a role in managing costs and ensuring appropriate use of care.
Further updates are expected as insurers continue implementing electronic systems and refining prior authorization practices in coordination with providers.
