Who Should Use These Tools?

Small Practices

Small practices should consider Infinitus for its per-use pricing model that avoids large enterprise commitments. If phone-based PA is a major bottleneck, Infinitus can deliver quick ROI. For electronic PA, evaluate whether your EHR vendor offers built-in PA tools before investing in a standalone platform.

Hospitals & Health Systems

Health systems benefit most from Rhyme Health's provider-side automation with EHR integration, or Waystar if you already use their RCM suite. Prioritize solutions that integrate with your existing EHR and can handle the full PA lifecycle including denials and appeals at scale.

Digital Health Companies

Health tech startups building PA workflows should evaluate Cohere Health's API capabilities for payer-side integration or Myndshft's rule-mapping engine. Consider whether you need to handle phone-based PA (Infinitus) or electronic submissions, and build your integration strategy accordingly.

Frequently Asked Questions

What is prior authorization AI and how does it work?

Prior authorization AI uses machine learning to automate the process of requesting and obtaining approval from health insurers before delivering care. These tools map clinical data to payer rules, auto-populate submission forms, and in some cases make real-time approval decisions.

How much can PA automation reduce turnaround times?

Leading PA AI tools report reducing turnaround times from an average of 5-14 days to under 24 hours for many authorization types. Real-time auto-approval for straightforward cases can bring decisions down to minutes.

Should providers and payers use different PA tools?

Yes. Cohere Health and similar platforms are built for payer workflows, while Rhyme Health and Waystar serve provider organizations. Using a tool designed for your side of the transaction ensures better integration and workflow alignment.

What is the typical ROI timeline for PA automation?

Most organizations see measurable ROI within 3-6 months of full deployment, primarily through reduced staff time on PA tasks, faster approvals, and lower denial rates. Enterprise implementations may take 6-12 months for full rollout.

Can AI PA tools integrate with my existing EHR?

Most enterprise PA tools offer EHR integrations with major systems like Epic and Cerner. Rhyme Health and Waystar are particularly strong in provider-side EHR integration. Check for pre-built connectors with your specific EHR before committing.
