We compared five prior authorization software tools on what decides the purchase: who does the work after you sign, which steps of the request each tool covers, whether it handles medical or pharmacy benefits, how it’s priced, and who takes the portal checks, payer calls and fax follow-up that electronic requests still leave to staff.
TL; DRThe best prior authorization software is the one that covers the authorizations filling your week and still works when a payer leaves its own portal. Recurring therapy, ABA, and home health authorizations worked for you – Silna Authorizations in the same suite as claims and eligibility – Waystar Touchless requests where your payers sit on a shared network – Rhyme A free multi-payer portal for a small practice – Availity Medication requests – CoverMyMeds Payer portal navigation, calls, and fax follow-up inside your own software – MindK (pre-built agents fitted to your payers) |
Prior authorization software cuts the hours your front desk spends in payer portals looking up rules, filling forms, and checking whether a request has moved. Most tools automate parts of that work for your staff. Silna adds its own team to work the payer follow-up.
Payers are moving to electronic prior authorization, but the rules cover only part of the work. Under the CMS Interoperability and Prior Authorization rule (CMS-0057-F), Medicare Advantage, Medicaid, and CHIP plans have had to decide standard requests within 7 calendar days and urgent ones within 72 hours since January 1, 2026. By January 1, 2027, these plans and federal exchange plans must also offer a Prior Authorization API that tells a provider whether a service needs approval, which documents to send, and where the request stands.
The API still leaves gaps. Commercial plans and drug requests fall outside the rule. Delegated review vendors such as eviCore and Carelon run their own portals. A payer can pend a request and ask for more records, and a peer-to-peer review happens on the phone. So staff keep logging in to portals, calling payers, and faxing notes for a large share of requests.
That is why most tools on this list combine two approaches. They send electronic requests where a payer accepts them and automate the portal, phone, and fax work for everything else, with software or with the vendor’s own team. The tools differ in who does that manual part.
How We Compared Prior Authorization Tools
We went through each vendor’s site, case studies, and press releases on October 12-16, 2026. When a vendor cited a CMS rule or a payer policy, we checked the original document. For every tool, we noted who does the work after you sign, which steps it covers, whether it handles medical or pharmacy benefits, and how it’s priced.
MindK builds AI agents, which is a different kind of purchase, so we describe it after the five.
Where the Work Piles Up in a Specialty Practice
An authorization looks like one task on a worklist. In practice, it is five separate jobs, and a group that bills a dozen payers learns a dozen versions of each.
| Step | What staff do today | What tends to go wrong |
|---|---|---|
| 1. Check the requirement | Look up the procedure (CPT) code against the payer’s list, which the payer can update during the year | The practice treats without approval, and the claim comes back denied |
| 2. Build the request | Pull the diagnosis, plan of care, notes, and the payer’s own form | A missing document leads to a pend or a denial |
| 3. Submit | Portal, X12 278 transaction, phone, or fax, depending on the payer | eviCore and Carelon review for many plans and run their own portals, so one payer can mean two logins |
| 4. Chase the payer | Call or log in for status, upload the note the payer requested, book the peer-to-peer call | Pended requests have no owner, so the payer’s request for records sits unanswered |
| 5. Track the approval | Enter the authorization number, dates, and approved units in the EHR or practice management (PM) system | Visits go past the approved count, or the approval ends mid-treatment |
The volume adds up fast. In the American Medical Association’s 2025 prior authorization survey of 1,000 physicians, released in May 2026, physicians reported 40 authorizations a week and 13 hours of physician and staff time spent on them. Two in five said they employ staff who work only on prior authorization.
Prior Authorization Software Compared by Who Does the Work
Each tool below sends electronic requests (X12 278 transactions or a payer network like Rhyme’s) where it can. The table shows who handles the portal, phone, and fax work that remains: your staff or, with Silna, the vendor’s team.
| Tool | Who does the work | Steps covered | Benefit | Pricing |
|---|---|---|---|---|
| Silna | Silna’s platform and team; your staff answer escalations | Payer rules, request, submission, follow-up, renewals | Medical | Quote, based on authorization volume |
| Waystar | Your staff, with automation inside Waystar’s revenue cycle suite | Requirement check, initiation, submission, status | Medical, incl. inpatient direct admissions | Not published |
| Rhyme | A payer-provider network connected to your EHR | Submission, status, touchless processing where the payer participates, gold carding | Medical | Not published |
| Availity | Your staff, in one multi-payer portal | Submission, attachments, status for participating payers | Medical | Free registration; Essentials Pro on request |
| CoverMyMeds | The prescriber’s staff send each request | Medication request, status, renewal from an earlier request | Pharmacy | Free for providers and their staff |
1. Silna Health: Recurring Authorizations Handled by the Vendor
Silna is built for authorizations that come back every few months, such as ABA programs, physical, occupational and speech therapy plans of care, and home health episodes. It also covers nephrology, orthopedics, and radiology. Once a week each location gets an email listing approvals close to expiring, which gives therapists time to write the progress note before the renewal goes out.
Silna reports that its customers’ average turnaround fell from 29 days to under 7. That is the core of its prior authorization automation: the vendor’s team keeps working the payer until a decision arrives.
| Best for | ABA, therapy, and home health groups that re-authorize the same patients every few months |
| Steps covered | Payer rules, request, submission, follow-up, renewals |
| Benefit | Medical |
| Pricing | Quote, based on authorization volume |
Watch for scope. Silna describes its product as built for outpatient and post-acute care. A group that also needs hospital or medication authorizations will run a second tool next to it.
2. Waystar: Authorizations Inside a Revenue Cycle Suite
Waystar sells authorization tools as part of a revenue cycle platform for health systems, large groups, and billing companies. Its Authorization Manager checks each order against what Waystar describes as 6.8 million payer rules, starts the request and monitors its status. Auth Accelerate, added in February 2025, automates submission. Waystar reports that Atlantic Health System cut its average time to initiate an authorization by more than 50%.
For teams already sending claims and eligibility checks through Waystar, authorizations appear in the same worklist under one contract. A billing company can run this prior authorization platform for every client practice and train staff on a single tool.
| Best for | Health systems, large groups, and billing companies already on Waystar |
| Steps covered | Requirement check, initiation, submission, status |
| Benefit | Medical, including inpatient direct admissions |
| Pricing | Not published; quoted on request |
Expect an implementation project and an enterprise contract, and ask whether Auth Accelerate sits in the base price or on a separate line.
3. Rhyme: Touchless Requests Where Payers Share the Network
Rhyme connects providers and payers inside the EHR. When a payer takes part, the request moves without a portal, a call, or a fax, and Rhyme can process it with no staff touch. Rhyme says it handles more than 4 million authorizations a year for 83 of the largest health systems and works with more than 300 of the largest payers. It also supports gold carding, where a payer drops the authorization requirement for providers with a strong approval record.
In Ohio, Medical Mutual, Cohere Health, and Rhyme set up touchless authorizations for Cleveland Clinic, Ohio State University Wexner Medical Center and OhioHealth. The example shows the conditions this kind of electronic prior authorization software needs: the payer, the network, and the health system all agree on one path.
| Best for | Health systems whose payers already sit on Rhyme’s network |
| Steps covered | EHR-integrated submission, status, touchless processing, gold carding, shared dashboard |
| Benefit | Medical |
| Pricing | Not published |
Check the payer list before signing. Rhyme’s customers are mostly large health systems, so a clinic or billing company should ask which of its own payers sit on the network and who works the requests that fall outside it.
4. Availity: One Free Login for Many Payers
Most practices already log in to Availity Essentials to check eligibility. The same account has an Authorizations & Referrals tool under Patient Registration. Staff submit X12 278 requests there, attach records, and check status. Registration is free, so a small practice can try this prior authorization solution before paying for anything. Staff still do the lookups, data entry, and uploads themselves.
Coverage depends on the payer. Blue Cross and Blue Shield of Texas, for example, sends authorizations managed by eviCore or Carelon to those vendors’ own portals. Florida Blue moved its AuthAI requests for sleep, radiology, and spine services into the standard Essentials authorization screen in April 2026. AuthAI recommends a decision to the health plan, and Availity says the tool does not approve or deny requests.
| Best for | Small and mid-size practices that want to test electronic submission at no cost |
| Steps covered | Multi-payer submission, attachments, status for participating payers |
| Benefit | Medical |
| Pricing | Free registration; Essentials Pro on request |
5. CoverMyMeds: Medication Requests at No Cost to Providers
CoverMyMeds, a McKesson company, is built for prescriptions. Staff send electronic prior authorization (ePA) requests for any drug to any plan at no cost and can copy an earlier request when a renewal is due. Some plans steer prescribers to it: Highmark lists CoverMyMeds as its preferred way to receive ePA requests.
Therapy visits, imaging, and procedures need one of the other tools. Practices that prescribe in DrFirst can also use its ePA tool, which since August 2026 handles medication and medical requests in the e-prescribing screen.
| Best for | Prescribers whose plans accept ePA requests |
| Steps covered | Medication requests, status, renewals |
| Benefit | Pharmacy |
| Pricing | Free for providers and their staff |
Other Tools That Touch Prior Authorization
Several vendors cover prior authorization as one job among many. Voice agents from Infinitus, SuperDial, VoiceCare AI, and Prosper AI call payers about authorization status. Infinitus focuses on pharma hubs and specialty pharmacies, and SuperDial on billing companies with high call volume. We compared them in our guide to AI voice agents for healthcare RCM.
Patient access platforms such as Notable and Innovaccer Flow add authorization checks to registration and scheduling. Cohere Health, Banjo Health, and Availity AuthAI work on the payer side. A practice can’t buy them, though it benefits when its payers use them. Experian Health’s Authorizations product fits hospitals that already use Experian for patient access.
When Off-the-Shelf Tools Can’t Reach Your Payers: MindK
Packaged tools work best when your payers sit on their network or portal. Specialty practice groups and billing companies with complex payers carry a second queue of self-funded plans, delegated review vendors, phone-only payers, and portals that change without notice. That queue stays with staff. MindK works on a hybrid model. Most of each agent is assembled from pre-built blocks that already run in production for MindK’s own RCM product, and MindK configures the rest to the payers on your roster and your workflows. The agents run inside your existing software. They don’t depend on payer APIs. They work through portals, phone, and fax, which covers the payers that electronic requests don’t reach.
The MindK prior authorization (PA) agent pulls coverage data, fills in each payer’s form and follows up by portal, phone, or fax until the payer answers. Cases it can’t finish go to staff with the context the agent collected. When a payer redesigns its portal, the agent records which step broke and parks those cases in a review queue for staff. The authorization number, dates, and approved units go to your EHR or PM system, into the fields your billing team reads. For phone follow-up, the MindK AI voice agent sorts every failed call into one of 13 outcome classes, so staff see why a call failed and what to try next.
MindK first built its payer portal navigation and voice agents for GoodBilling, MindK’s own RCM software for medical practices. GoodBilling handles eligibility, benefits verification, and claims. It has onboarded 300 practices. If you want to own the workflow, MindK can build it as custom revenue cycle management software on the same components.
How to Choose Prior Authorization Software
Pull a month of your own authorizations before you book demos. Then ask each vendor these questions and test the answers against your payers and services.
| Question for the vendor | Why it matters |
|---|---|
| Which of my payers and service lines does the tool cover today? | Portal and network coverage differs by payer, and delegated review vendors often sit outside it. |
| Who owns a request after the payer asks for more information? | A tool that only flags the case as pending leaves your staff to find the missing note and send it. |
| Who gets warned before an approval runs out? | Silna emails each location weekly about approvals close to expiring. |
| Where do the authorization number, dates, and units end up? | Billing reads the authorization number, dates, and units from the record. If the tool keeps them in its own dashboard, someone types them in again. |
| What is the plan for payers’ Prior Authorization APIs? | Medicare Advantage, Medicaid, CHIP, and federal exchange plans must offer the API by January 1, 2027. Commercial plans and drug requests stay outside the rule. |
FAQ: Choosing Prior Authorization Software
Can I do my own prior authorization?
As a patient, usually not. Payers want clinical notes from the chart, so the request comes from your provider’s office. You can call the number on your insurance card to ask whether a service needs approval or where a request stands. A practice can run every request by hand, and many small ones do. Groups usually start looking at software once authorizations take up most of one person’s week.
Can AI do prior authorization?
Partly. In a DrFirst pilot, its AI filled 63% of pharmacy benefit manager question sets with no clinician edits. Payers run AI on their side as well, and six in 10 physicians in the AMA’s 2025 survey said they worry it will raise denial rates. So software can take the forms and status checks. A disputed request still needs a clinician.
How much does prior authorization cost?
For a practice, most of the cost is staff time plus claims denied for care delivered without approval. Software starts at free: CoverMyMeds for medications and Availity Essentials registration. Silna prices by authorization volume, and Waystar and Rhyme quote enterprise contracts. Patients don’t pay for the request itself, but they can owe the full bill if care goes ahead without approval.
How to automate prior authorization?
Start by sorting a month of requests by payer and by channel. Payers that accept electronic X12 278 requests, or that work with Rhyme’s network, are the easiest to automate with packaged software. Phone and fax payers are harder. They need either a vendor team, as Silna offers, or AI agents built for those channels, such as MindK’s payer portal and voice agents.
