Prior authorization software submits, tracks and manages pre-approval requests to health plans, replacing the phone calls, faxes and portal logins most practices still rely on. Tools range from simple electronic submission to AI-powered automation that gathers clinical data and checks payer criteria. The right choice depends on your authorization mix, payers and EHR.
Key takeaways
- Prior authorization software falls into four categories. Picking the wrong category is the most expensive mistake practices make.
- AI prior authorization tools can gather clinical data, check payer criteria and track status, but clinical judgment stays with your team.
- Automation depth varies widely, from fixed rules to genuine AI. Ask vendors to show which steps are automated and which still need staff.
- A federal rule requires many payers to offer a prior authorization API from 2027, so ask how each vendor plans to use it.
- The phone side of prior authorization, such as patient and pharmacy calls, usually needs a separate layer.

Why prior authorization software matters
The manual prior authorization process is one of the most time consuming jobs in a medical practice. In an AMA survey of 1,000 physicians conducted in late 2024, practices completed an average of 39 prior authorization requests per physician each week, and physicians and their staff spent about 13 hours a week on them. Forty percent of physicians said they have staff who work exclusively on prior authorizations.
That administrative burden falls on medical staff who could be working on patient care, and delays in prior authorization decisions affect the patient experience. Good prior authorization software reduces manual tasks, cuts down on phone calls and status checks, and gives the team one place to see where every request stands.
What does prior authorization software actually do?
At minimum it replaces manual submission. Beyond that, capability varies more widely in this category than in almost any other practice software.
Electronic submission. Requests go to the payer through an electronic channel rather than fax or portal. This is the baseline, and it is not universal. Some health plans still require portal submission for certain services, so ask which of your payers are covered electronically.
Requirement checks. The tool checks whether a service needs authorization for the patient’s plan before the request is built, so staff find out before the patient is scheduled rather than after.
Status tracking. A single view of every pending request, rather than staff calling payers for updates. The value grows with your volume.
Payer criteria library. Some platforms maintain a library of prior authorization criteria for each plan, updated as payers change requirements. This is the feature that prevents unnecessary submissions, and it is the hardest one to evaluate in a demo.
Documentation assembly. Pulling clinical notes, medical records, imaging and prior therapy history from the chart to show medical necessity. Quality varies considerably, and this is where most staff time is actually spent.
Appeals support. Tracking denial reasons, deadlines and appeal status. Frequently absent, and frequently the thing practices need most. If denials are your problem rather than submissions, check this specifically.
What are the four categories of prior authorization software?
The categories matter more than the individual products, because choosing the wrong one wastes the evaluation entirely.
Pharmacy and electronic prior authorization (ePA). Built for prescription drugs and connected to pharmacy benefit managers. Strong payer coverage for medications, limited or no support for medical procedures. If your authorization burden is mostly medications, this is the right category.
Medical prior authorization platforms. Handle procedures, imaging and services. Usually sold as part of a wider platform rather than standalone, which affects both price and implementation time.
EHR-native modules. Authorization functionality built into your existing EHR. Lowest friction because there is no second system, but you are limited to what your EHR vendor has built, and it is usually a licensed add-on.
Practice management integrations. Authorization tied to scheduling inside a practice management system. Useful when authorization delays are causing rescheduled or cancelled appointments.
A practice with heavy imaging volume and a practice with heavy specialty medication volume need different categories. Establish which describes you before you look at a single product.
How does AI prior authorization work?
AI-powered automation is now the main way vendors describe this category. A typical AI prior authorization workflow has five steps:
- Trigger. A provider orders a procedure, test or medication that may need pre-approval, and the tool flags it.
- Clinical data gathering. Using natural language processing, the tool reads clinical notes and patient data in the EHR and pulls out the required information, such as diagnoses, prior treatments and test results.
- Payer criteria check. The tool compares the clinical information against the health plan’s prior authorization criteria and flags anything missing before submission.
- Submission. The completed prior authorization request goes to the payer through its electronic channel or portal.
- Status tracking and follow-up. The tool monitors the request and alerts staff when the payer decides or asks for more information.
Rules-based vs AI automation depth
Automation depth is the biggest difference between AI solutions in this category. Some tools follow fixed rules: if the service and plan match a list, a form is pre-filled. Others use machine learning and advanced AI to read unstructured clinical notes and handle more variation. Ask each vendor to walk through a real request from your practice and show exactly which steps the tool completes and which still need healthcare staff, including complex cases and edge cases.
Can AI do prior authorizations?
AI can take on much of the manual work of the prior authorization process: finding the required information, filling in forms, checking criteria and tracking status. It does not replace clinical judgment. Clinical staff still need to confirm medical necessity, handle complex cases and respond to denials.
There is also an important distinction in how AI is used. Health plans use artificial intelligence on their side too, and physicians are concerned about it: the AMA reports that more than 60% of physicians are concerned that unregulated AI tools used by payers are increasing denials. For a practice, the goal is AI that helps your team submit complete, accurate requests, with a person reviewing the decisions that matter.
What does the CMS prior authorization rule mean for software?
The CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F) sets new requirements for many payers, including Medicare Advantage plans and Medicaid programs:
- Faster decisions: Impacted payers must send prior authorization decisions within 72 hours for urgent requests and seven calendar days for standard requests, mostly starting in 2026.
- A prior authorization API: Impacted payers must implement an HL7 FHIR-based Prior Authorization API, with compliance dates generally beginning January 1, 2027.
- Public metrics: Impacted payers must publicly report prior authorization metrics each year.
- Drugs are excluded: The rule applies to medical items and services, not prescription drugs.
For practices evaluating software, the practical question is how each vendor plans to connect to payer prior authorization APIs as they come online, and whether your EHR will support that connection.
What should you ask a prior authorization software vendor?
Ask these before the demo and get the answers in writing.
- Which of our specific payers do you support electronically, and which still require portal or fax submission?
- Do you handle medical authorizations, pharmacy authorizations, or both?
- Does the tool write approval status back into our EHR, or does staff re-enter it?
- How is your payer criteria library maintained, and how quickly are changes reflected?
- Which steps are automated with AI, and which still need staff? Show us on one of our real requests.
- Does the platform track denials, appeal deadlines and authorization expiry?
- How will you connect to payer prior authorization APIs under the CMS rule?
- What is included at our tier, and which functions cost extra?
The first question matters most. A platform with excellent coverage of payers you rarely see is worth less than a basic one that covers your top five.
How do you measure whether it is working?
Set a baseline before implementation, or you will have no way to judge the result.
Time per authorization. Track staff minutes from request initiation to decision. This is the number most likely to improve and the easiest to measure.
First-pass approval rate. The share of requests approved without additional documentation or appeal. Better documentation assembly should move this.
Turnaround times. Days from submission to decision, which translates directly into how long patients wait for care.
Denial rates. Requests denied because information was missing or criteria were not met. Track the reasons, not just the totals.
Expired authorizations. Approvals that lapsed before the service was delivered. A small number, but each one means starting over.
Where does voice AI fit with prior authorization software?
Prior authorization software works on submission and tracking. It does not answer the phone, and a large part of prior authorization work still arrives by phone: patients asking whether their authorization came through, pharmacies calling about a medication, and payers calling with updates or requests for more information.
That is where AI voice agents fit, as a separate layer alongside your prior authorization tools and EHR. Simbie’s AI voice agents handle the phone side of prior authorization. They take prior auth requests and status calls from patients, pharmacies and payers, check the practice’s insurance rules when scheduling, and send each request to the practice’s prior authorization team as a task in the EHR. Simbie does not submit prior authorizations to payers.
Simbie integrates with Epic, eClinicalWorks, ModMed EMA, gGastro, EZDerm and Nextech, is HIPAA-compliant and is SOC 2 Type II certified. See our EMR compatibility guide for AI voice agents for how that integration works.
Frequently asked questions
What is prior authorization software?
Prior authorization software is a tool that helps healthcare providers submit, track and manage requests for pre-approval from health plans before a service or medication is provided. It replaces manual phone calls, faxes and portal checks with an electronic workflow.
Can prior authorization be automated?
Much of it can. Prior authorization automation can check requirements, gather clinical data from the EHR, fill in forms, submit requests and track status. Clinical review, complex cases and appeals still need staff.
What is electronic prior authorization (ePA)?
Electronic prior authorization, or ePA, generally refers to medication authorizations completed electronically through pharmacy benefit managers, often from within the e-prescribing workflow. Medical prior authorization covers procedures, imaging and services.
How much does prior authorization software cost?
Pricing models vary between per-transaction, per-provider subscription and inclusion within a wider platform contract. Most vendors do not publish pricing and quote against practice size and volume. Ask what is included at your tier, since documentation assembly and appeals tracking are often priced separately.
How long does implementation take?
It depends on integration depth and the number of payer connections. EHR-native modules are quickest because there is no second system. Larger platforms take considerably longer and usually need dedicated project time from your team.
Is AI prior authorization software HIPAA compliant?
It can be. Look for a vendor that signs a Business Associate Agreement, encrypts patient data, uses access controls and audit logs, and holds independent certification such as SOC 2 Type II. Our guide to HIPAA-compliant AI covers what to check.
How can a practice get prior authorizations approved faster?
Submit complete requests the first time. Check whether authorization is required at scheduling, include the clinical notes that show medical necessity against the payer’s criteria, and track every request in one place. For the basics of the process, see our guide to what prior authorization is in healthcare.
Before you choose a prior authorization tool
The decision that matters is the category, not the feature list. A pharmacy-focused platform will not solve a medical authorization backlog, and a large platform is overbuilt for a two-provider clinic.
Establish which category fits, confirm coverage for your specific payers, check how much of the workflow is truly automated, and measure your current time per authorization before anything changes. Those steps narrow the field faster than any comparison table.
