CombineHealth vs Waystar

Waystar files a 10-K with the SEC. It listed on Nasdaq (WAY) in June 2024, has principal offices in Lehi, Utah, and closed its $1.25 billion Iodine Software purchase around October 1, 2025. CombineHealth's Y Combinator listing gives Winter 2023, San Francisco and Active.

The two cover overlapping tasks. Waystar covers financial clearance, eligibility, authorizations, claim monitoring, remittance, denial recovery, appeals and patient payments, and says it reaches 60% of the U.S. patient population. CombineHealth's tagline is "The AI workforce for healthcare revenue," with a separate AI employee for each step from coding to an RCM analyst that tracks 50+ KPIs. Waystar's homepage gives no EHR list, while CombineHealth's homepage names twelve. Waystar shows HITRUST, SOC 2, PCI and HIPAA badges without scope, and CombineHealth shows a SOC 2 badge without a type.

A practice on CareCloud or Greenway that wants discrete AI coders, billers and appeal writers has CombineHealth's list in front of it. Waystar is the pick where a health system's procurement reads SEC filings.
