Achieving a ∼99% first pass ratio and $1.9M cost reduction through AI-enabled radiology RCM

Overview

A leading U.S.-based radiology billing company, managing a massive portfolio with net patient revenue (NPR) of $2B—$3.5B, has partnered with Firstsource for over a decade. Since 2012, we have served as their strategic operational engine, managing comprehensive end-to-end revenue cycle management (RCM) services.

This deep integration has allowed the client to focus on customer acquisition and growth while Firstsource took care of the operational complexity. Thus, the client has been able to maintain their position as a market leader.

As the client expanded rapidly and volumes increased, sustaining performance with a purely human-driven operating model became increasingly difficult. Firstsource led a technology-led transformation, introducing AI-powered automation to maintain accuracy, accelerate collections, and support continued growth at scale.

Challenges

  • Volume growth pressure: Rapid business expansion created spikes in coding and billing volumes that strained manual workflows.
  • Operational scalability limits: Traditional human-led processes risked delays in reconciliation, coding turnaround, and SLA adherence.
  • Margin protection: Increasing operational complexity threatened the client’s cost-to-collect and long-term profitability.
  • Need for technology-led evolution: The client required a shift from a people-powered operating model to a technology-enabled one to sustain growth and competitiveness.

How We Made It Happen

Leveraging our deep institutional knowledge of the client’s business, Firstsource led a comprehensive transformation of the services we provide:

  • From manual to autonomous coding: We didn't just optimize; we innovated. We deployed our proprietary autonomous coding platform "Codessence," shifting the bulk of our established workflow from manual execution to AI automation. This ensured speed and accuracy at a scale human teams alone couldn't match while maintaining the clinical nuance and payer-specific expertise required for radiology billing.
  • End-to-end ownership: We continued to manage the full revenue cycle but upgraded the machinery. We integrated software bots for payment posting (electronic remittances), removing manual lag times.
  • Strategic continuity: Because we were already their trusted partner, this wasn't a disruption; it was an evolution. We seamlessly integrated these new technologies into the existing offshore workflows, ensuring stability while unlocking new capacity.

The technology-led transformation strengthened the client’s ability to scale operations while delivering measurable financial impact for both the client and their customers.

Conclusion

By combining deep operational expertise with AI-driven automation, Firstsource transformed a traditional RCM engagement into a scalable, technology-led model. The partnership enabled the client to sustain industry-leading performance while expanding their business without increasing operational overhead.
