CodaMetrix
Autonomous coding spun out of Mass General Brigham
Our take
CodaMetrix automates professional-fee medical coding for health systems. Spun out of Mass General Brigham in 2019, its platform grew from a homegrown tool inside the Massachusetts General Physician Organization's billing office into a multi-specialty autonomous coding engine covering radiology, pathology, surgery, and more. It reads clinical documentation, assigns codes autonomously where confidence is high, and routes the rest to human coders, with customers reporting on average a 60% reduction in coding costs, 70% fewer denials, and cash arriving about five weeks sooner.
The company has raised over $110M, including a $55M Series A led by SignalFire in 2023, a $40M Series B led by Transformation Capital in 2024, and an $11.65M extension in May 2025. Its customer list is a who's who of academic medicine: Mass General Brigham, Mount Sinai, Yale Medicine, Henry Ford Health, and University of Colorado Medicine, together representing 200+ hospitals and tens of thousands of providers. Availability in the Epic Toolbox since 2024 shortens implementation for the Epic-based systems that make up its core market.
What it does
- Autonomous coding of professional-fee charges from clinical notes
- Covers radiology, pathology, surgery, and other specialties
- Routes low-confidence cases to human coders
- Clinically enriches claims data for audit and compliance
- Customers report 60% coding cost and 70% denial reductions
Where it's strong
- Spun out of Mass General Brigham's own billing operation, so the product was proven on real academic-center volume before it was sold.
- Reference customers are elite academic systems (MGB, Mount Sinai, Yale, Henry Ford) with published outcome figures.
- Confidence-based routing to human coders is an honest architecture: it automates what it can prove, not everything.
What buyers should weigh
- Value scales with volume; it is built for large Epic-based health systems, not small physician groups.
- Coverage is by specialty and service line, so confirm your highest-volume departments are actually supported.
- At roughly $110M raised it is well capitalized for its niche but much smaller than the RCM incumbents it displaces.
