AI Transforms Prior Authorization Process

What is Prior Authorization?

Prior authorization represents one of healthcare’s most entrenched administrative processes—an insurer approval protocol that has become synonymous with delays, red tape, and complicated relationships between patients, providers, and payers. This healthcare AI revolution is about to change everything.

Pittsburgh-based Highmark Health, operating its multi-state insurance services and 14-hospital Allegheny Health Network, is now collaborating with Abridge to compress what can be a monthslong process into the length of a single patient visit. Ambient AI technology quietly handles the heavy lifting in the background, providing patients with clarity before they leave the exam room.

Origins of Prior Authorization

Prior authorization began in the late 1960s and early 1970s as a cost-control mechanism for private insurers and early managed care organizations. Initially designed to avoid unnecessary hospitalizations, physicians needed insurers’ advance approval for only a narrow set of high-cost procedures and drugs. However, as managed care expanded, so did prior authorization’s scope and complexity.

The Traditional Prior Auth Problem

Administrative Burden Statistics

Over the last 15 years, the prior authorization process has become widespread and divisive. Recent healthcare administration data reveals alarming trends:

• More than 50% of insured adults report their insurer required prior authorization for needed services in the past two years
• 73% of the public view insurers’ delays and denials as a “major problem”
• The process accounts for $35 billion of U.S. healthcare administrative spending annually
• Average cost per authorization ranges from $40-$50 for private payers and $20-$30 for providers

Real-World Impact on Patient Care

Mark Sevco, president of Allegheny Health Network, describes the pre-authorization approval process as “difficult, to say the least. It’s time-consuming with high administrative costs, involving multiple phone calls and conversations.”

Even Dr. Shiv Rao, Abridge founder and CEO, experienced the prior auth slowdown firsthand while working as a cardiologist. When he ordered a cardiac MRI, it triggered weeks of “paper cuts”—eligibility questions, debates over whether a CT should come first, and calls to insurance-side clinicians to make his case.

Highmark and Abridge Partnership

Revolutionary Timing Change

This healthcare technology partnership marks several significant firsts in the industry:

• Changes timing of prior authorizations from post-visit to during-visit
• Represents a new frontier for ambient AI in clinical documentation
• Demonstrates capability to transform free-form patient-clinician conversations into completed administrative tasks
• Reorders traditional healthcare workflows to happen as part of the conversation

Strategic Collaboration Benefits

The agreement represents a notable plot twist in a landscape where the AI race between insurers and providers seemed poised to make prior authorization worse. This partnership leverages Abridge’s experience with tens of millions of recorded and documented patient-physician conversations.

How Real-Time AI Authorization Works

Contextual Reasoning Engine Technology

Abridge’s prior authorization solution, powered by its Contextual Reasoning Engine, operates through sophisticated healthcare AI processes:

1. Leverages clinical conversation content and context
2. Interprets meaning using advanced natural language processing
3. Maps conversations to patient health plan policies
4. Integrates into documentation workflow seamlessly
5. Surfaces fine-print requirements for each diagnosis, order, or prescription

Real-Time Processing Capabilities

Richard Clarke, PhD, chief analytics officer at Highmark Health, emphasizes the complexity: “The enablement of that seamless experience is not simple. There are actually a lot of complex questions that need to get answered.”

The AI technology must:

• Navigate Highmark-specific prior authorization policies at scale
• Determine approval eligibility in real-time
• Detect physicians’ recommended diagnostics from ongoing clinical conversations
• Map recommendations to appropriate CPT codes
• Flag missing requirements before visit completion

Benefits for Patients and Providers

Improved Patient Experience

Ambient documentation technology has already demonstrated significant wins:

• 92% of patients reported their providers were more attentive during visits
• Patients receive real-time clarity about coverage before leaving
• Eliminates uncertainty about procedure coverage on surgery day
• Reduces wait time from weeks/months to minutes

Enhanced Provider Satisfaction

Clinical documentation AI provides substantial benefits for healthcare providers:

• Dramatic reductions in after-hours charting or “pajama time”
• Eliminates weeks of administrative follow-up
• Enables clinicians to focus entirely on patient care
• Builds trust through transparent AI reasoning and evidence sharing

Cost Reduction and Efficiency

The healthcare administration improvements include:

• Significant reduction in administrative costs
• Elimination of multiple phone calls and conversations
• “Get it right the first time” approach reduces rework
• Streamlined workflow integration across healthcare systems

Testing and Implementation Strategy

Integrated Delivery Network Advantage

As an integrated delivery network, Allegheny Health Network’s insurer-provider structure makes it an ideal testbed for Abridge’s capabilities. This structure allows for:

• Trial innovations before expanding to other provider partners
• Testing across New York, Delaware, and West Virginia markets
• Co-development of frontier products with payer mindset
• Strategic partnership leveraging AHN’s significant Highmark revenue relationship

Comprehensive Rollout Plan

Abridge will support more than 50 million medical conversations in 2025 across 150-plus partners. The AHN rollout extends beyond physician practices to include:

• Hospital medicine departments
• Emergency departments
• Nursing documentation systems
• Home health services

Mr. Sevco notes: “Most institutions just take it and use it in physician practice. We’re making a significant investment knowing physicians are overwhelmed and burned out.”

Future of Healthcare AI

Challenging Industry Perceptions

This collaboration defies stubborn perceptions that healthcare lags behind other industries in technology adoption. Clarke notes: “There’s lots of assumptions that all these other industries are moving at a different pace than healthcare. Right now, that is actually not true.”

Vision for Zero Wait Times

Sevco articulates AHN’s ambitious goal: “Our dream and ambition is wait time zero, so that patients get care when and where they need it. Leveraging AI to cut through bureaucracy, eliminate waste, and follow clear clinical guidelines means we can do it right the first time.”

Collaborative vs. Competitive AI Future

The partnership represents a departure from the AI arms race providers have feared, where each side adopts algorithms to outmaneuver the other. Dr. Rao explains: “Our work with Highmark and AHN shows that it doesn’t need to be that sort of negative-sum mindset of AI versus AI. Instead it can be a partnership, and AI can be a tool that is a bridge between payer and provider.”
