Arintra, a leading GenAI-native autonomous medical coding platform for healthcare providers, has raised $21 million in a Series A funding round led by Peak XV Partners, with participation from Endeavor Health Ventures, Y Combinator, Counterpart Ventures, Spider Capital, Ten13, and other strategic investors. The new funding will accelerate product development, scale the team, expand adoption across health systems and physician groups nationwide, and establish a new Bay Area headquarters.
Healthcare providers face tightening margins, coder shortages, and increasingly complex payer requirements. Arintra addresses these challenges by going beyond traditional autonomous coding to deliver Revenue Assurance — a proactive, outcomes-driven approach ensuring accurate, efficient, and compliant reimbursement. This model streamlines revenue cycles, reduces costs, and provides tangible ROI.
“At Arintra, we bring together autonomous medical coding, clinical documentation improvement, and denial prevention in a single platform,” said Preeti Bhargava, Co-founder and CTO of Arintra. “By helping providers document what was done, code what was documented, and properly support what was charged, we enable them to secure full, compliant reimbursement at a lower cost, with fewer delays and significantly less manual effort.”
Arintra has processed over $1 billion in healthcare charges, recovering millions in otherwise missed revenue while reducing manual work and accelerating cash flow.
- At Mercyhealth, Arintra delivered a 5.1% revenue increase, 43% fewer denials on automated claims, a 50% reduction in work queue aging, and a 32% drop in coding costs. At Reid Health, it improved coding accuracy and sped up accounts receivable.
“We chose Arintra because it integrates deeply with Epic and changed how we code without disrupting our workflows. We went from billing delays and high denials to faster A/R and fully automated charge capture. It is one of the few AI tools that delivers hard ROI, fast,” said Muhammad Siddiqui, CIO of Reid Health.
The company’s founding was inspired by Bhargava’s personal experience of receiving an unexpectedly large bill due to a coding error after an emergency department visit, revealing the broader systemic issues in medical coding and reimbursement. This led Bhargava and co-founder Nitesh Shroff, both computer science PhDs, to reimagine medical coding as a strategic driver of healthcare’s financial health.
“Reimbursement in healthcare is fundamentally broken. Payers are moving fast, using policy and technology to shift more burden onto providers, but autonomous coding hasn’t kept up,” said Shroff. “We built Arintra to help healthcare providers secure compliant revenue at scale while easing the burden on frontline teams.”
Mohit Bhatnagar, MD at Peak XV, added: “The disruption of the $150 billion healthcare reimbursements industry will be one of AI’s defining impacts. Arintra’s autonomous system tackles one of the hardest challenges for providers; translating clinical documentation into accurate insurance codes so they get paid fairly and fast. The results speak for themselves; providers are recovering millions in lost revenue by partnering with Arintra. It is a great example of vertical AI done right – real enterprise adoption, clear ROI, and an ambitious roadmap as models continue to improve. After backing Nitesh and Preeti at seed through our Surge Program, Peak XV Partners is excited to double down and lead Arintra’s Series A round.”
Arintra’s GenAI-native platform blends large language models with clinical knowledge graphs to interpret patient charts in context and apply specialty-specific coding rules precisely. All codes generated are fully explainable and auditable, fostering trust in a high-stakes environment. The system integrates natively with leading EHRs such as Epic and Athena, operating seamlessly within existing workflows.
With measurable ROI, proven customer impact, and a deep understanding of healthcare’s revenue challenges, Arintra is positioned to become the go-to partner for revenue assurance as it expands capabilities and adoption nationwide.
