Best Prior Authorization Automation Tools
A ranked look at the platforms that take the fax machine out of prior auth. And the point where a group's workflow needs engineering instead.
The short answer
For most practices, start where your payers already are: Availity's essentials cover the portal work, and Waystar or Cohere Health automate at scale. Once your PA flow spans an EHR, payer portals and staff queues nothing connects, the workflow is a build.
This page ranks platforms a practice can adopt today. Hashlogics builds HIPAA-conscious automation where those platforms stop, and we do not sell a PA product. We sit outside the ranking as the custom option, and we say so plainly.
How this was ranked
Verified
The published numbers on prior auth are stark. Surveys cited by athenahealth and Rivet put the load near 40 requests per physician per week, costing staff around 13 hours, much of it still by phone and fax. Most doctors say the process delays care. We read each vendor's published capabilities and payer coverage, then scored them against that workload.
We build document and intake automation ourselves, including an insurance audit platform that reads documents and proves the number it produces. The criteria below decide whether automation removes the queue or adds a portal to it.
- Intake coverage
- How much of the request, status-check and appeal loop the tool actually runs.
- Payer reach
- Which payers and portals it covers, because the long tail is where staff time goes.
- EHR fit
- Whether it reads and writes your EHR, or staff copy between screens.
- Multi-location fit
- One queue and one report across sites, or one login per clinic.
- Compliance posture
- BAAs, audit trails and access controls a compliance officer will sign.

Ranked
Best fit first, judged on staff hours actually removed from the PA queue.
The payer network most practices already touch every day
Availity sits between providers and a large share of payers, so eligibility checks and auth submissions run through one portal instead of many. For a small practice, using it well is the cheapest real improvement. It consolidates the work rather than removing it, and staff still drive the queue.
Best for
- Practices drowning in per-payer portals and phone trees
Not for
- Groups expecting end-to-end automation from it alone
- Model
- Payer network portal
Auth automation as part of a full revenue cycle platform
Waystar automates auth checks and submissions inside a suite that also covers claims, denials and payments. Groups already shopping for revenue cycle tooling get PA relief as part of the package. Buying the suite only for prior auth is heavy.
Best for
- Groups modernizing the whole revenue cycle at once
Not for
- A practice that only wants the PA queue fixed
- Model
- RCM suite
Clinical intelligence for the specialties where PAs are heaviest
Cohere applies clinical rules and AI to the auth decision itself, and several large payers run it on their side of the fence. Where your payers use it, approvals speed up without your staff changing much. Its value to you depends on payer adoption you do not control.
Best for
- High-PA specialties whose payers run intelligent auth programs
Not for
- Practices whose payer mix sits outside those programs
- Model
- Clinical AI decisioning
An AI that waits on hold with payers so staff do not
Infinitus points voice AI at the worst part of the queue: the phone calls for benefits and auth status. Where the phone is the bottleneck, that is a direct hour-for-hour save. It automates the call, and your team still owns the rest of the workflow.
Best for
- Groups whose staff spend hours on hold with payers
Not for
- Practices whose queue pain is portals and paperwork, not calls
- Model
- Voice AI for payer calls

A custom PA workflow build
Where the queue spans systems none of these tools connect
In many groups, the real PA workflow is glue. Orders start in the EHR, requirements live on payer sites, status lives in portals, and staff run the joins from a spreadsheet queue. A build automates those joins: reading the EHR, preparing submissions, chasing status, and routing only exceptions to people. Under a BAA, with an audit trail, on your infrastructure.
It costs more than the platforms above and is wrong where Availity plus discipline would do. It is right for multi-location groups where the queue itself is a full-time job.
Best for
- Multi-location groups running PA queues from spreadsheets
- Practices whose EHR and payer mix defeat packaged coverage
Not for
- A single-site practice with a manageable queue
- Our build
- Document automation that proves its numbers
- Who starts it?The EHR order, or a sticky note.
- Who chases it?Software, or your best staffer.
- Exceptions only?People should see the hard 10%.
- Provable?An auditor asks who approved what, when.
Automation should shrink the queue, never add a portal to it.
When none of these is the right answer
Prior auth tooling fails in a specific way: each tool covers part of the loop, so practices stack tools, and staff become the integration. The eligibility tool, the payer portal, the status spreadsheet and the EHR all disagree, and the phone rings anyway.
Health data raises the bar for any fix. Whatever automates this loop must run under a BAA, log every access, and keep patient data off systems that train on it. Ask that question before any demo.
- 01Portal chaos? Consolidate on Availity first. It is the cheapest real win.
- 02Phone-hold hours? Infinitus attacks exactly that.
- 03Staff as the integration between EHR, portals and spreadsheets? That glue is the build.

Questions buyers ask
01What is the best prior authorization automation for a small practice?+
Start with Availity to consolidate payer portals, and add Infinitus-style call automation if phone holds are the bottleneck. Full automation platforms earn their cost at group scale. Below that, discipline plus consolidation beats new software.
02Can prior authorization be fully automated?+
Not entirely, and vendors who claim otherwise are selling. The routine majority of requests can run without a human, with software preparing, submitting and chasing them. The hard minority needs clinical judgement, and a good system routes exactly those to people.
03Is it safe to automate workflows that touch patient data?+
Yes, with conditions: a signed BAA, audit trails on every access, role-based controls, and no patient data sent to systems that train on it. How you build HIPAA-compliant AI is its own topic, and we keep a full answer on that.
04Why isn't [specific tool] on this list?+
We ranked platforms with published capabilities we could verify by the date above. This category moves fast. Absence is not a judgement, only a limit of what we could confirm.
