Arintra, a GenAI-native autonomous medical coding platform for healthcare providers, has secured $21 million in Series A funding. Peak XV Partners led the round, with Endeavor Health Ventures, Y Combinator, Counterpart Ventures, Spider Capital, Ten13, and other strategic investors also participating. The company plans to use the funds to accelerate adoption across health systems and physician groups nationwide, strengthen product development, scale its team, and open a new Bay Area headquarters.
Expanding Adoption and Scaling Nationwide
The new capital gives Arintra the fuel to meet the surging demand for automated, accurate, and efficient medical coding. The startup already integrates its platform into major health systems and physician groups, and it now intends to accelerate this rollout. With growing pressure on providers to capture every dollar of reimbursement accurately, Arintra’s expansion strategy targets rapid penetration in both large hospital networks and smaller physician practices.
By establishing a Bay Area headquarters, Arintra positions itself closer to top-tier AI talent and healthcare innovation hubs. This move supports its hiring plans for engineers, clinical informaticists, and implementation specialists. The company aims to scale both technical capacity and customer success resources to maintain the speed and quality of deployments as adoption widens.
A GenAI-Native Platform Built for Healthcare Realities
Arintra’s platform stands out because it operates as a GenAI-native solution built from the ground up for autonomous medical coding. Rather than bolting AI onto existing processes, the system embeds itself directly within electronic health records (EHRs) like Epic. This deep integration eliminates workflow disruption and prevents data integrity risks, two common pitfalls of earlier coding automation attempts.
The platform reads clinical documentation, understands medical context, and assigns accurate insurance codes—all without human intervention. It blends advanced generative AI models with deep clinical expertise to ensure precise coding that complies with complex payer policies. By automating the coding process entirely, Arintra reduces the manual workload for hospital coding teams and speeds up the billing cycle.
Muhammad Siddiqui, Chief Information Officer at Reid Health, shared the transformation his organization experienced: “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 accounts receivable and fully automated charge capture. It is one of the few AI tools that delivers hard ROI, fast.”
Tackling a Broken Reimbursement System
In the U.S., healthcare reimbursement processes suffer from complexity and shifting payer requirements. Payers increasingly rely on technology and policy changes to transfer more administrative burden to providers. Inaccurate coding often results in claim denials, delayed payments, or underpayments—problems that cost providers millions annually.
Nitesh Shroff, Arintra’s Co-founder and CEO, addressed the issue directly: “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. We built Arintra to help healthcare providers secure compliant revenue at scale while easing the burden on frontline teams.”
By applying generative AI to this challenge, Arintra turns clinical notes into precise, billable codes that match insurer rules. Providers no longer have to choose between speed and accuracy, and they can recover revenue that would otherwise be lost.
Delivering Measurable ROI for Providers
One of Arintra’s core strengths lies in its ability to deliver a clear, measurable return on investment. Providers who adopt the platform see fewer claim denials, faster payments, and reduced accounts receivable cycles. Hospitals and physician groups report recovering millions in revenue that traditional manual coding or less advanced automation tools failed to capture.
The system’s end-to-end automation eliminates human error, streamlines workflows, and frees skilled coding staff to focus on complex or unusual cases. This not only boosts revenue but also improves job satisfaction for staff, who can shift from repetitive coding tasks to higher-value responsibilities.
Investors See Vertical AI at Its Best
Mohit Bhatnagar, Managing Director at Peak XV Partners, outlined the strategic importance of Arintra’s work: “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.”
Bhatnagar also highlighted Peak XV’s long-standing relationship with Arintra’s founders, noting that the firm first backed Nitesh and co-founder Preeti during its Surge seed program. The Series A investment reflects strong confidence in the team’s ability to scale and maintain a competitive edge.
Competitive Edge in a Rapidly Evolving Space
Arintra enters a growing field of AI-powered medical coding tools, but its deep EHR integration and fully autonomous approach differentiate it from competitors. Many existing solutions still require human oversight for a large portion of cases, slowing throughput and limiting cost savings. Arintra’s technology targets complete automation while maintaining compliance and accuracy standards that meet or exceed human coders.
The company’s focus on vertical AI—tailoring models specifically for the healthcare reimbursement domain—ensures that its platform understands the nuances of clinical language, diagnosis codes, and payer rules. This specialization, combined with a user-centric design that avoids workflow changes, helps drive adoption among healthcare organizations that might otherwise resist new technology.
A Roadmap for Continuous Improvement
With the Series A funding, Arintra plans to invest heavily in advancing its AI models, expanding to cover more specialties, and adapting to evolving payer policies in near-real time. The company will also explore new features such as predictive analytics for denial prevention, automated appeals generation, and tighter integration with revenue cycle management tools.
By continually updating its models with new clinical and coding data, Arintra intends to stay ahead of both regulatory changes and technological advancements. This commitment to continuous improvement aims to reinforce the trust of current customers and attract new ones across the U.S. healthcare system.
Easing the Burden on Frontline Teams
Beyond the financial benefits, Arintra addresses the staffing shortages and burnout facing healthcare providers. Medical coders often manage overwhelming workloads and face pressure to meet accuracy and speed targets. By automating routine coding tasks, Arintra reduces stress on these teams, enabling them to focus on more complex cases that require human judgment.
This shift not only supports employee well-being but also improves the resilience of health systems struggling to recruit and retain skilled coders. With Arintra, providers can maintain revenue integrity even when staffing levels fluctuate.
Shaping the Future of Healthcare Reimbursements
As AI adoption accelerates in healthcare, platforms like Arintra showcase how technology can deliver tangible, enterprise-level results. By combining generative AI with deep domain expertise and seamless EHR integration, the company addresses a critical pain point for providers: ensuring accurate, timely reimbursement without adding administrative burden.
Arintra’s Series A funding marks a significant step in its journey to redefine medical coding and revenue cycle management. With strong investor backing, a clear ROI proposition, and a roadmap for innovation, Arintra stands poised to lead the transformation of the $150 billion healthcare reimbursements industry.
