Bottom line

  • Pick Fathom if you code high chart volumes and want most encounters coded autonomously, and can fund a multi-month EHR integration.
  • Pick Solventum if you are a large hospital that wants the incumbent market-standard coding, CDI, and grouping stack with decades of regulatory content behind it.

Fathom

High-volume autonomous coding across specialties

Founded
2016
HQ
San Francisco, CA
Stage
Series B
Raised
$61M+

What it does

  • Codes encounters autonomously with deep learning and NLP
  • Automates 90%+ of coding volume in many deployments
  • Covers ED, radiology, primary care, and other specialties
  • Routes low-confidence charts to human coders
  • Improves HCC/RAF capture for value-based contracts
  • Reduces coding cost, denials, and days to bill

Where it's strong

  • Highest published automation rates in the autonomous coding market, with customer-verified results like Your Health's 95.5% automation at 98.3% accuracy.
  • Epic Toolbox listing and multi-specialty deployment model shorten implementation for health systems.
  • Strategic backing from CVS Health Ventures and clinical investors like Cedars-Sinai signals enterprise credibility.

What buyers should weigh

  • Narrowly focused on coding, so you still need separate vendors for the rest of the revenue cycle.
  • Automation rates vary a lot by specialty and documentation quality; your mix may not hit headline numbers.
  • Total disclosed funding is modest relative to peers, worth probing on enterprise support depth.

Solventum (formerly 3M Health Information Systems)

The incumbent coding and CDI platform, adding autonomous coding

Founded
2024
HQ
St. Paul, MN
Stage
Public (NYSE: SOLV)
Raised
n/a

What it does

  • 360 Encompass computer-assisted coding and CDI platform
  • Autonomous coding that finalizes 80%+ of qualified outpatient charts
  • Over 1 million proprietary coding rules as guardrails
  • Grouping, reimbursement, and quality methodologies (MS-DRG, APR-DRG)
  • Semi-autonomous fallback workflow for complex visits

Where it's strong

  • Decades of coding content, terminologies, and payment methodologies that startups have to rebuild from scratch.
  • Already installed in most large US hospitals, so autonomous coding can be turned on without a new vendor relationship.
  • Public-company stability and a compliance track record that eases legal and audit review.

What buyers should weigh

  • Autonomous coding is a newer bolt-on to a legacy platform; automation rates and chart eligibility trail some startup claims, so test on your own case mix.
  • Enterprise contracts are large and multi-year, with less pricing flexibility than per-chart startup models.
  • The company is mid-restructuring after the 3M spinoff, with a $500M cost-cutting program that buyers should watch for support impact.
