Quick answer: Adonis and AKASA both appear on health-system AI RCM shortlists. Adonis is an orchestration and revenue-intelligence layer on Epic and athenahealth. AKASA is a mid-cycle platform for coding, CDI, and denial operations. Pick Adonis when you want intelligence and agents on the current Epic or athena team. Pick AKASA when the program is documentation quality and mid-cycle denials.
Inclusion criteria: Head-to-head on deployment model, EHR fit, payer coverage, and whether you must replace a clearinghouse or BPO.
Honest limitations: Substrate does not replace a clearinghouse, EHR, coder, or patient-billing platform. It automates post-submission AR. Claim status includes denial root-cause analysis (eligibility, records, medical necessity, wrong route), not just a 277 code or an 835 variance. Clinical edge cases still go to staff. Coding, CDI, and patient-facing billing are out of scope.
At a glance
Where Adonis wins
- Denial trend and payer-behavior dashboards for in-house teams
- athenahealth marketplace plus Epic Connection Hub
- Outcome-based pricing conversations without a coding-platform RFP
Where AKASA wins
- Coding and CDI as the primary AI job
- Health-system mid-cycle operating redesign
- Buyers who already have orchestration and still miss documentation quality
Also consider Substrate
Also consider Substrate when the gap is post-submission follow-up on the current PM: live in days, EDI and portal coverage across 3,500+ payers, PM writeback with a video audit trail, and denial root-cause analysis as part of claim status (eligibility, records, medical necessity, or wrong route) rather than a 277 code or an 835 variance alone. Substrate does not replace a clearinghouse, EHR, coder, or patient-billing platform. Adonis orchestrates; AKASA codes. Portal status that names the root cause still sits beside both.
