Arintra has raised a $25 million Series B funding round to modernize traditional healthcare revenue cycle management systems for providers and health systems, including its clients UC Davis Health, MercyHealth, Meritus Health, Rochester Regional Health, Reid Health, and Mercy Medical Center.
Define Ventures led the Series B investment round with participation from existing investors, including Peak XV Partners, Yale New Haven Health (YNHH) Center for Health Care Innovation, Endeavor Health Ventures, Y Combinator, Counterpart Ventures, Ten13, Spider Capital, and Endeavor Health.
Including the latest funding round, Arintra has raised $51 million in equity funding to date. With this Series B round, Arintra will invest in expanding across more enterprise health systems, deepen its clinical coverage across 23+ specialties, and extend the platform to new areas of the revenue cycle.
Arintra is building and transforming a revenue assurance platform, an agentic AI approach built to close the gap between care delivered and revenue earned. Its platform already processes more than $5 billion in annual claim value for leading healthcare enterprises representing over $50 billion in combined net patient revenue, all of them trusting the platform to help them get paid accurately and fairly.
Why it matters
According to data provided by Arintra, U.S. healthcare is a $5 trillion system, but most health systems and provider groups struggle to get paid by payers for the care they deliver due to siloed processes that are riddled with inaccuracy, costing health systems, providers, and patients every day.
Karen Linder, Senior Director of Health Information Management & Coding at Rochester Regional Health, said: “We chose Arintra because of the breadth of its platform, its ability to support multiple specialties, and its proven experience with complex health systems. We began with a high-volume specialty, where we’ve already seen meaningful results, and are now expanding into additional areas. What’s most compelling is the opportunity to bring greater automation, consistency, and efficiency to coding at scale while giving our teams the transparency and control they need.”
