Quick answer: Adonis is an AI orchestration layer on Epic and athenahealth. Infinx is a patient-access and claim-status platform (prior auth, eligibility, Claim Status Agent) with portal and TPA execution and human review. Pick Adonis for revenue intelligence on Epic or athena. Pick Infinx when prior auth and scheduled status rechecks are the purchase.
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
- Health-system intelligence on Epic Connection Hub
- athenahealth practices that want marketplace orchestration
- Denial trends and payer behavior without buying a PA platform
Where Infinx wins
- Prior authorization as the primary pain
- Portal and TPA claim status with scheduled rechecks
- Buyers who need an access vendor, not an Epic intelligence layer
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. Infinx is the closer status peer. Adonis is the closer intelligence peer. The overlay is for teams that want the unpaid reason written back without a new orchestration or access platform.
