Arintra
Autonomous medical coding that runs inside your EHR
Our take
Arintra, founded in 2020 by AI PhDs Preeti Bhargava and Nitesh Shroff and based in Austin, sells autonomous medical coding: its system reads clinical documentation and produces billing-ready coded claims without a human coder touching qualifying charts. It runs inside Epic and athenahealth rather than as a separate application, which keeps HIM and revenue cycle workflows intact. Buyers are hospitals, health systems, and physician groups trying to cut coding cost, denials, and days in AR.
The company is a Y Combinator alum that raised a $21M Series A led by Peak XV Partners in September 2025, bringing total funding to about $21.5M, and says it has processed over a billion dollars in charges. Named customers include Mercyhealth, where it reported a 5.1% revenue increase and 43% denial reduction on automated claims, and Reid Health. It competes with Solventum and Optum on one side and startups like CodaMetrix and Fathom on the other; its pitch is deeper autonomy with in-EHR deployment, and its main gap is a short public reference list.
What it does
- Fully autonomous coding from clinical documentation
- Works inside Epic and athenahealth, no workflow change
- Denial reduction and revenue capture on automated claims
- Coding audit trails and compliance documentation
- Specialty coverage across outpatient service lines
Where it's strong
- Published customer results are specific and strong: 5.1% revenue lift and 43% fewer denials on automated claims at Mercyhealth.
- Direct-to-billing autonomy rather than coder-assist, which is where the cost savings actually are.
- In-EHR operation means no new workqueue tool for HIM teams to learn.
What buyers should weigh
- Small named customer list so far; ask for references in your specialty mix and payer mix.
- A Series A vendor carries more long-term viability risk than Solventum or Optum for a core RCM function.
- Verify coverage for your setting; published wins skew toward outpatient and professional coding.
