Bottom line

- Pick Nym if you have high-volume ED, radiology, or outpatient coding and can fund a months-long integration to take humans out of the loop entirely.
Arintra
Autonomous medical coding that runs inside your EHR
- Founded
- 2020
- HQ
- Austin, TX
- Stage
- Series A
- Raised
- $21.5M
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.

Nym
Explainable autonomous coding for ED and outpatient
- Founded
- 2018
- HQ
- New York, NY
- Stage
- Growth equity
- Raised
- $94.5M
What it does
- Fully autonomous coding with zero human touch
- Assigns ICD-10 and CPT codes in seconds per chart
- Explainable audit trail justifying every code
- Covers emergency medicine, radiology, outpatient surgery, urgent care
- Processes over six million charts annually
Where it's strong
- True zero-touch autonomous coding, with codes assigned in seconds and no human in the loop for in-scope charts.
- Explainability is the differentiator: every code comes with a traceable justification, which audit and compliance teams value.
- Deployed in 40+ US hospitals including Geisinger and Ochsner, processing over six million charts a year.
What buyers should weigh
- Supports six service lines (ED, radiology, outpatient surgery, outpatient visits, inpatient professional, urgent care); everything else still needs coders.
- Charts falling outside the engine's confidence threshold route back to your human coding staff, so plan for a hybrid operation.
- A new CEO (Lori Jones) arrived in April 2026, so watch for strategy and roadmap shifts.
