Quick answer: Infinx and Availity both show up on claim-status shortlists but they are different products. Availity Advanced Real-Time Claim Status is 276/277 into the EHR for enrolled payers. Infinx’s Claim Status Agent hits portals and TPAs, rechecks on a schedule, and keeps humans on exceptions. Use Availity when enrolled EDI is enough. Use Infinx when portal-only and specialty vendors are the queue.
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 Infinx wins
- Portal and TPA status when 277s are missing, stale, or empty
- Prior auth and patient access in the same vendor family
- Recurring rechecks (Infinx cites multi-hour cycles) with staff on exceptions
Where Availity wins
- National payer connectivity and a free or low-cost eligibility/claims hub
- Real-time 276/277 into Epic for enrolled payers
- REST/FHIR APIs and a network you may already be on
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. Keep Availity for submission and enrolled 277s. Infinx is the closer status peer. The overlay job is classifying the unpaid reason and writing the next action back, not another connectivity network.
