What We Set Out to Improve.

Industry
HealthTech

High-volume Utilization Management (UM) requiring automated clinical policy enforcement.

How We Worked
Dedicated product team

Healthcare Architect + Language AI Specialists + HIPAA Compliance Lead embedded within Clinical Ops.

Goal
Payer-Provider Automation

Accelerating Prior-Auth decisions by matching live clinical notes against complex policy criteria.

What We Built
AI-powered Care Platform

A practical solution designed around the client’s existing tools, teams, and day-to-day workflow.

What Was Getting in the Way.

The client’s prior-authorization process relied on manual faxes and disconnected portal uploads. This Challenge created a 3-5 day response time in care determinations, leading to provider burden and increased risk of clinical denials due to missing documentation.

The biggest issues were care response time, administrative leakage, and provider churn. The team needed a faster, clearer way to manage the work while keeping the right checks in place.

Care Response Time
Manual reviews delayed life-critical treatments, resulting in lower patient satisfaction and potential adverse events.
Administrative Leakage
High touch-costs for simple authorizations were cannibalizing the medical loss ratio (MLR).
Provider Churn
Slow medical necessity checks damaged provider-network relationships and trust.
