After years of complaints from physicians, patients, and policymakers, major U.S. health insurers promise to streamline the long-dreaded prior authorization process. These promises come in response to growing federal pressure, lawsuits, and widespread public frustration over treatment delays.

On June 23, 2025, the U.S. Department of Health and Human Services  (HHS) and the Centers for Medicare & Medicaid Services (CMS) announced a new agreement with over 50 major health insurers to overhaul the prior authorization process. These companies—including UnitedHealthcare, Aetna, Blue Cross Blue Shield affiliates, and CVS Health—committed to reforms that will affect over 257 million Americans.

The initiative, coordinated by America’s Health Insurance Plans (AHIP), aims to make prior authorization faster, more transparent, and easier for both patients and providers. AHIP President and CEO Mike Tuffin said insurers are working to “deliver a more seamless patient experience and enable providers to focus on patient care, while also helping to modernize the system.”

Kim Keck, President and CEO of the Blue Cross Blue Shield Association, called the reforms “a meaningful step forward” in building a better system powered by technology and interoperability.

The Prior Authorization Problem

Prior authorization (PA) is the process by which insurers must approve certain medications, procedures, or specialist visits before coverage is granted. Initially designed as a cost-control mechanism, it has become synonymous with delays, denials, and administrative gridlock.

An American Medical Association survey found that 94% of physicians reported care delays due to PA requirements. Even for those with insurance, access to care was often at the mercy of paperwork and call center queues.

These burdens have triggered bipartisan concern. Lawmakers and patient advocacy groups alike have criticized PA as both opaque and outdated too often leaving patients in limbo and providers entangled in bureaucracy.

The Insurers' New Playbook

In response, some of the nation's largest insurers have announced voluntary moves to automate and expedite prior authorization processes. New AI-driven tools aim to process requests faster, and some insurers have committed to reducing the number of services that require PA altogether.

These efforts mirror CMS’s new federal rules, which require Medicare Advantage and Medicaid plans to respond to urgent PA requests within 72 hours by 2026 (CMS). But private insurers are not bound by the same enforcement mechanisms. This raises concerns about consistency and follow-through.

Automation may speed up the process, but it does not guarantee transparency, nor does it fix the fragmented structure that made prior authorization necessary in the first place.

Promises on Paper

According to the pledge, insurers will adopt real-time electronic prior authorization (ePA) systems by 2027, reduce the number of services requiring PA, and ensure that authorizations remain valid for at least 90 days—even when patients switch plans.

These reforms aim to cut administrative burden, reduce care delays and improve transparency for both patients and providers. The commitments include:

  • Standardizing electronic prior authorizations using FHIR-based technology
  • Reducing the number of services subject to PA by January 1, 2026
  • Honoring existing authorizations during plan transitions
  • Increasing transparency around decisions and appeals
  • Expanding real-time decisions by 2027
  • Requiring medical professionals to review all clinical denials

AI: The Shadow Behind the Streamlining

Earlier this year, the AMA also warned that insurers were increasingly relying on artificial intelligence to issue automated denials of care. These systems often generate "batch denials" with minimal human oversight, leading to delays, confusion, and in some cases, patient harm.

A March 2025 Investopedia report revealed that UnitedHealthcare’s AI-powered system, NaviHealth, contributed to a dramatic increase in denied post-acute care claims. Experts have warned that these tools lack transparency and are poorly regulated.

AI may speed up approvals but it’s also making it easier to deny care without oversight.

The Policy Gap

Despite the June pledges, insurers are not required to track or report the impact of AI on prior authorization outcomes. Nor are they bound by regulation to human-review thresholds or transparency standards.

That lack of enforceability has some experts calling for federal legislation that defines how AI can be used in medical decision-making and when humans must step in. These reforms may modernize paperwork, but without guardrails, AI may still call the shots.

The Road Ahead

Insurers say they want to rebuild trust. The June pledge is a signal that the industry is aware of its growing credibility crisis, especially among providers.

But true reform requires more than statements of intent. It demands transparency, accountability, and policy that matches the pace of technology.
