Arintra raises $25Mn for autonomous medical coding
TEXAS, UNITED STATES — Arintra raised $25 million in a Series B round led by Define Ventures, bringing total capital raised since the company’s founding to $51 million. Peak XV Partners, which led the prior Series A, returned for the round alongside Yale New Haven Health Ventures, Endeavor Health Ventures, Y Combinator, Counterpart Ventures, Ten13, and Spider Capital.
The Texas-based company builds a generative artificial intelligence (AI) platform that automates medical coding across 23 specialties and all care settings.
Autonomous coding platform integrates into existing EHRs
Arintra said its medical coding platform uses generative AI and clinical knowledge graphs to read patient charts contextually and apply specialty-specific coding rules, integrating with Epic and Athena across inpatient, emergency, diagnostic, and ambulatory settings.
Health systems using Arintra have recorded a 5.1% increase in compliant revenue capture, a 32% reduction in coding costs, and a 43% decrease in coding-related denials, across a combined client base that collectively processes more than $5 billion in annual claim value.
The company said these results hold across both high-complexity inpatient cases and high-volume outpatient coding environments.
“U.S. health systems fail to collect billions annually, not due to care quality but fragmented, manual systems,” said Nitesh Shroff, co-founder and chief executive officer of Arintra.
Define Ventures leads $25 million Series B round
The $25 million will fund enterprise health system adoption, deeper clinical and specialty coverage, and extensions to Arintra’s artificial intelligence (AI) revenue cycle platform capabilities, including expanded integrations with major EHR and practice management systems.
Peak XV Partners’ return as a co-investor alongside a health system venture arm (Yale New Haven Health Ventures) and an established operator (Endeavor Health Ventures) signals that Arintra’s platform is gaining traction with health system buyers, not just financial investors evaluating market opportunity.
“Revenue cycle management is essential and increasingly important as many face financial and labor challenges,” said Chirag Shah, partner at Define Ventures.
Arintra’s Series B reflects growing investor appetite for AI platforms that address structural inefficiencies in healthcare revenue cycle management (RCM), where manual coding processes remain a primary driver of claim denials and revenue leakage across health systems of all sizes.
For the healthcare outsourcing sector, the funding signals mounting automation pressure on offshore and nearshore medical coding operations, as AI platforms demonstrate auditable accuracy across complex specialty workflows that have historically required experienced human coders.
As autonomous coding adoption scales across enterprise health systems, the business case for maintaining large dedicated coding workforces, whether in-house or through outsourced providers, faces increasing pressure from AI-generated performance benchmarks.
