AI speeds prior auth but raises costs: PHTI
- Health plans now spend $40 to $50 per prior authorization cycle
- Physician practices absorb $20 to $30 per prior auth transaction
- Level 5 prior authorization volume grew 5% since AI deployment
- U.S. prior authorization spending reached $2.3 billion annually
WASHINGTON, UNITED STATES — Health plans deploying artificial intelligence (AI) for prior authorization are processing more requests in less time while spending more per transaction, as physician practices absorb rising costs with no relief in administrative burden.
According to Fierce Healthcare, the findings come from the Peterson Health Technology Institute (PHTI) in its April 2026 report, “Administrative AI: Current Use and Potential Impact.”
Costs rise as AI speeds decisions
The PHTI report found that health plans using artificial intelligence now spend $40 to $50 per prior authorization cycle, while physician practices absorb $20 to $30 per transaction.
These figures represent an increase from pre-automation baselines, with prior authorization volume at Level 5, the most complex tier, growing 5% since health plans began deploying AI tools.
According to the report, automation has added review steps rather than replaced them, layering additional verification cycles onto existing payer workflows.
“The frustration physicians feel about prior authorization is well documented, and AI is not yet solving it,” said Caroline Pearson, senior fellow at PHTI.
Aggregate spending on prior authorization across United States health systems reached $2.3 billion annually, according to PHTI.
Bot wars add costs on physicians
Health plans and physician practices are both deploying AI to manage prior authorization, creating what PHTI describes as a “bot wars” dynamic in which automated systems generate and respond to requests without human intervention.
The result is a high-volume exchange that drives up per-cycle costs on both sides without resolving individual cases faster for patients.
Some provider organizations now spend more than $1,000 per physician per month on prior authorization staffing and technology, even after automation investments.
The Centers for Medicare and Medicaid Services (CMS) finalized rule CMS-0057-F, requiring payers to respond to prior authorization requests within 72 hours for urgent cases and seven days for standard requests. However, the regulation does not set limits on the administrative costs that either side may incur in meeting those timelines.
Physician groups and health system administrators are examining staffing models and vendor arrangements as prior authorization costs climb. The demand for specialized support has grown alongside AI adoption, as organizations weigh building in-house capabilities against outsourcing transaction-heavy administrative functions.
Some health systems are turning to top healthcare outsourcing companies that specialize in revenue cycle management and claims processing to contain rising costs.
Business process outsourcing (BPO) firms have expanded their healthcare practices to include AI-assisted authorization workflows, offering fixed-cost models that transfer administrative risk away from physician practices and health systems.
