Bottom line

  • Pick AKASA if you run a mid-size or large health system, ideally on Epic, and want generative AI working claims, auths, and coding in-house instead of outsourcing staff.
  • Pick Fathom if you code high chart volumes and want most encounters coded autonomously, and can fund a multi-month EHR integration.

AKASA

Generative AI for coding and revenue cycle operations

Founded
2018
HQ
South San Francisco, CA
Stage
Series B
Raised
$205M

What it does

  • Generative AI medical coding trained on clinical documentation
  • Clinical documentation integrity (CDI) review at scale
  • Automates prior auth status and claims follow-up work
  • LLMs fine-tuned on customer clinical and financial data
  • Surfaces missed codes and documentation gaps pre-bill

Where it's strong

  • Cleveland Clinic co-developed and is now deploying its GenAI CDI product across all US locations, a rare tier-one clinical validation.
  • Deep pockets ($205M raised) and deployment across 650+ hospitals reduce vendor-viability risk.
  • Focus on mid-revenue-cycle (coding plus CDI) fits health systems that want one vendor for both.

What buyers should weigh

  • The company pivoted from RPA-style automation to generative AI, so ask which product generation you are actually buying.
  • Flagship proof points are large academic systems; fit and pricing for smaller hospitals is less proven.
  • Last disclosed raise was 2022, so probe current burn and roadmap funding.

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.
