Prior Authorization and the $54 Billion Administrative Problem

Prior authorization consumes an estimated $54 billion annually in administrative cost across US healthcare, according to JAMA Network Open's most recent analysis. That figure includes the physician time spent initiating requests, the clinical staff time spent managing documentation requirements, the payer staff time spent reviewing requests, the patient time spent waiting for approvals, and the downstream cost of care delays and their clinical consequences. It is, by any measure, one of the most expensive administrative processes in US healthcare — and one that produces no clinical value in the vast majority of cases it processes.

The prior authorization process was originally designed to ensure that high-cost, potentially inappropriate treatments received independent clinical review before payer coverage was confirmed. In practice, the overwhelming majority of requests — estimates range from 80 to 95 percent, depending on the analysis — are eventually approved. The administrative machinery exists primarily to delay and complicate access, not to prevent inappropriate care.

This creates a market structure that is genuinely suited to AI-driven disruption. The AI that is winning in prior authorization is not replacing clinical judgment — it is eliminating the administrative friction that precedes and surrounds clinical decisions that have already been made. A clinical AI that reads a physician's order, identifies the payer's specific coverage criteria, assembles the supporting clinical documentation from the patient record, and submits a structurally complete prior authorization request automatically is reducing the physician workflow friction while improving the payer's ability to review the request accurately.

Our portfolio company Cohere Health operates directly in this space, connecting payers and providers through an intelligent authorization platform that improves both approval rates and turnaround times while maintaining payer control over coverage decision-making. The regulatory environment is also moving in the same direction: CMS's 2024 prior authorization rule requires payers to implement FHIR-based prior authorization APIs, which creates an interoperability layer that well-architected authorization AI platforms can leverage to eliminate manual form-based request submissions. The compliance mandate is, again, a product opportunity for the right companies.
