Minimizing Prior Authorization Processing Time with AI-Driven Clinical Evidence Automation

Client Background

A Fortune 10 Digital Health company involved in distributing pharmaceuticals and medical supplies and equipment

Client Need

When providers submit Prior Authorization (PA) requests via EHR systems, the clinical data is often incomplete or inconsistent. Different PA question sets and criteria keep the process highly manual, forcing teams to interpret patient history, pull out supporting evidence, and fill in long forms.
Reduce delays and manual effort in the PA process
Address incomplete and inconsistent clinical data received with PA requests
Simplify interpretation of patient history and evidence extraction
Minimize manual completion of lengthy, varying PA question sets and criteria
Minimize administrative burden and back-and-forth communication with providers

Solution

Deployed an AI-driven PA automation solution that interprets a patient’s clinical story
Automatically completed required PA questions based on available clinical data
Reviewed diagnoses, labs, medications, prior treatments, and clinical notes to extract evidence
Generated evidence-supported responses aligned to branching logic and payer criteria
Reduced back-and-forth communication and administrative burden for clinical teams
Integrated in real time with PA request systems (via Kafka) to streamline clarifications and speed submission
Designed a scalable architecture that extends across drug categories, payers, and patient cohorts

Realized Benefits

50–70% reduction in manual effort for clinical data review and PA form completion
>90% accuracy in matching required criteria and branching decision logic
Decrease in administrative burden for client teams and clinicians
Standardization of evidence-extraction to ensure regulatory auditability

Tools & Technologies

By automating clinical evidence extraction and PA form completion, the client achieved faster and more accurate Prior Authorization processing, significantly reducing manual effort and administrative burden.
