SAN FRANCISCO, CA / August 21, 2025
Arintra, a healthcare technology startup founded by two machine learning PhDs, Nitesh Shroff, Preeti Bhargava, secured $21 million in a Series A funding round led by Peak XV Partners. The company is also backed by Endeavor Health Ventures, Y Combinator, FoundersX Ventures, Counterpart Ventures, Spider Capital, and Ten13. Its innovative AI-native autonomous coding platform transforms revenue cycle management for health systems by integrating autonomous medical coding, clinical documentation improvement (CDI), and payer-aware denial insights directly within electronic health record (EHR) systems -delivering revenue assurance at scale.
Addressing Healthcare Revenue Challenges
Hospitals face shrinking margins while grappling with unclaimed revenue due to complex coding processes, a shortage of skilled coders, and increasingly stringent payer requirements. Arintra's platform tackles these issues head-on by automating the coding process, ensuring accurate and efficient billing. Unlike many autonomous coding tools that merely convert patient charts into billing codes, Arintra adopts a comprehensive approach to deliver revenue assurance. It focuses on three key pillars:
- Documenting Services Performed: Capturing complete and accurate clinical documentation.
- Coding Based on Documentation: Generating precise billing codes that reflect the documented care.
- Supporting Charged Claims: Providing payer-aware insights to minimize denials and ensure audit-ready claims.
Proven Impact and Customer Success
Arintra's platform has processed over $1 billion in healthcare charges, helping customers recover millions in revenue that would have otherwise been lost. Notable outcomes include:
- Mercyhealth: Achieved a 5.1% revenue increase and a 43% reduction in claim denials for automated cases. Work-queue aging was halved, and coding costs dropped by 32%.
- Reid Health (Indiana): Transitioned from billing delays and high denial rates to faster accounts receivable (A/R) and automated charge capture, all without disrupting existing workflows.
With the new funding, Arintra aims to expand coverage across more medical specialties, enhance clinical documentation improvement, and bolster denial analytics. The company also plans to establish a new headquarters in the Bay Area to support its growth. CEO and co-founder Nitesh Shroff, PhD, stated, "Reimbursement is fundamentally broken. Our goal is compliant revenue at scale, without adding burden to clinical or IT teams."
FoundersX Ventures: An Early Believer in Arintra's Vision
FoundersX Ventures, a firm dedicated to pioneering technologies, supported Arintra from its inception, investing in its seed round with firm belief in its potential to transform hospital operations through AI and digital innovation, beginning with medical coding automation. Arintra initially targeted high-demand hospital departments like radiology, with plans to extend its solutions to emergency rooms (ERs) and primary care settings.
Arintra's impact on hospital revenue represents only the beginning of its potential to reshape healthcare operations. "It was eye-opening to learn that most U.S. hospitals operate on just 3% margins while losing 10-15% of revenue to insurance claim rejections, largely due to manual and outdated medical billing systems. Arintra is solving this massive problem with GenAI automation to save our hospitals." said Helen H. Liang, PhD, Managing Partner at FoundersX.
Arintra's AI-driven, end-to-end platform tackles these challenges by automating medical coding, enhancing claim accuracy, and minimizing revenue loss, setting the stage for broader operational improvements across healthcare systems.
Arintra delivers the industry's leading GenAI-native autonomous coding platform, empowering health systems to achieve accurate and efficient reimbursement for their services, ensuring revenue assurance at scale. By integrating advanced AI with deep clinical expertise, Arintra autonomously codes medical charts with high precision, eliminating the need for human intervention. Unlike standalone tools, Arintra seamlessly integrates into electronic health record (EHR) systems, enabling adoption without workflow disruptions or risks to data integrity. Health systems leveraging Arintra recover lost revenue from coding errors, documentation gaps, and unaddressed denials, achieving over 5% revenue uplift, 12%+ reduction in accounts receivable (A/R) days, and 43%+ fewer claim denials.
