FinThrive vs Infinx: Medical Necessity Appeals

Quick answer:

FinThrive is best for hospitals that want denial prevention, underpayment recovery, and appeal submission inside a revenue cycle platform. Infinx is best for provider groups that want prior authorization and denial follow-up in software, with specialists when a payer will not take an electronic request.

Inclusion criteria:

Honest limitations: Substrate does not replace a clearinghouse, EHR, or full-cycle BPO. It automates post-submission AR (status, appeals, posting, eligibility) and still routes clinical edge cases to staff. Coding, CDI, and patient-facing billing are out of scope.

FinThrive is best for hospitals that want denial prevention, underpayment recovery, and appeal submission inside a revenue cycle platform. Infinx is best for provider groups that want prior authorization and denial follow-up in software, with specialists when a payer will not take an electronic request. See Appeals.

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
