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
Substrate ARC is an agentic denial and reconciliation platform for provider groups, hospitals, and health systems. Substrate combines all your systems and data sources across clearinghouses, payer portals, EMRs, lockboxes and more, to comprehensively support your billing team and enable you to work every single denial. Consider Substrate if:
- You need end-to-end denial management, from triage through remediation, and appeal filing, not just phone dispositions
- Your payer mix is portal-heavy (Medicare, Medicaid MCOs, specialty commercial)
- You want structured PM writeback and audit trails across status, appeals, and posting
- You prefer agentic automation over manual execution or offshoring and outsourcing (Substrate is listed in the Anthropic Connector Directory and publishes a public claim-status MCP.)
- You want to keep billing in house but make it fast and cost effective
