Cohere Health vs JustAppeals: Medical Necessity Appeals

Quick answer:

Cohere Health is best for health plans and risk-bearing providers that review prior authorization and medical necessity on their own policies. JustAppeals is best for specialty practices and cancer centers that need prior-authorization appeal letters, submission checks, and peer-to-peer preparation.

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.

Cohere Health is best for health plans and risk-bearing providers that review prior authorization and medical necessity on their own policies. JustAppeals is best for specialty practices and cancer centers that need prior-authorization appeal letters, submission checks, and peer-to-peer preparation. See Appeals.

Where Cohere Health wins

  • Prior authorization automation at plan scale, including determination letters
  • Review Resolve surfaces the guideline next to the clinical record

Where JustAppeals wins

  • Letters are built from clinical notes and payer policy, including thin documentation
  • P2P Co-Pilot gives the physician the policy language before the peer-to-peer

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

Frequently asked questions

Is Cohere Health the same kind of product as JustAppeals?

No. Cohere Health is the plan's review of the request. JustAppeals is the practice's appeal of that decision and the prep for peer-to-peer.

Who should choose Cohere Health or JustAppeals?

Pick Cohere Health if you are the plan. Pick JustAppeals if you are the specialty practice writing the appeal.

Where does Substrate fit?

Substrate ARC files the provider appeal and writes the outcome back to the PM. It does not replace plan medical necessity review or a specialty P2P workspace.
