Nym
Explainable autonomous coding for ED and outpatient
Our take
Nym builds an autonomous medical coding engine that reads clinical charts and assigns ICD-10 and CPT codes in seconds with no human intervention. Founded in 2018 with headquarters in New York and R&D in Tel Aviv, it takes a computational-linguistics approach rather than a pure LLM one, which lets it produce an explainable audit trail justifying every code it assigns. It supports six service lines, with particular strength in emergency medicine and radiology, and works across Epic, Oracle Cerner, athenahealth, MEDITECH, and Allscripts.
Nym has raised $94.5M, most recently a $47M growth round led by PSG in late 2024 with participation from GV, Addition, and Samsung Next. It is deployed in more than 40 US hospitals, including Geisinger and Ochsner Health, and processes over six million charts annually. In April 2026 it brought in Lori Jones as CEO to lead its next growth phase. Against CodaMetrix it positions on full autonomy and explainability within its supported service lines, rather than breadth across every specialty.
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.
