10 Best AI Medication Prior Authorization Tools

Quick answer: The best AI medication prior authorization tools in 2026 split by who runs them and which drugs they cover. Honey Health leads for practices that want medication PAs submitted and chased across payers inside their existing EHR. Tandem and Develop Health automate pharmacy-benefit PA at the point of prescribing; SamaCare, Mandolin, and Silna specialize in buy-and-bill, infusion, and therapy drugs; Humata and Coral span drugs alongside other PA types; and Banjo and Basys are the AI the payer side uses to decide. The right pick depends on your drug mix and whether you're buying for the practice or the plan.

AI is reshaping medication prior authorization from both directions at once. On the provider side, agents now read the chart, file the request, and chase the payer for a decision. On the payer side, plans and PBMs are deploying AI to render those decisions — the same automation physicians say they trust least. "AI medication prior authorization" therefore means two different products depending on which seat you're in. This guide ranks the AI-native tools across both, with an honest best-fit and trade-off for each, starting with the practice-side agents.

How we evaluated these AI medication PA tools

We included tools built around modern AI — LLMs, machine learning, or autonomous agents — that do real medication PA work, serve US healthcare in 2026, and are HIPAA-compliant. We left out the incumbent ePA rails (covered in our general guide) since they route rather than reason. The dimensions that separated the field:

• Which side it serves — the practice submitting, or the payer deciding?
• Drug coverage — retail pharmacy, specialty, buy-and-bill, or therapy?
• Autonomy — assist, submit and chase, or decide?
• EHR fit — inside your existing systems, or a separate platform?
• Human-in-the-loop — what routes to a person, and when?

This isn't a single-winner ranking. A dermatology group automating biologic PAs and a health plan modernizing pharmacy UM need opposite tools, so each entry carries a clear "best for." Provider skepticism is real: the AMA's 2025 survey found only about one in three physicians trust the AI insurers use for PA decisions. This is the AI spoke of our medication PA software guide and part of the broader AI prior authorization hub.

AI medication PA tools at a glance

The 10 best AI medication prior authorization tools in 2026

1. Honey Health — best for end-to-end medication PA across payers

Honey Health runs medication PA as an AI staff member. Its agent identifies the requirement in the EMR, logs into the payer portal, submits the request with the clinical justification, monitors status over the days a payer takes, and writes the decision back to the chart. It uses agentic browser automation rather than an integration, so it works across 20+ EHRs and the payer portals themselves — including the payers that fall outside the clean ePA path and otherwise eat staff time.

Pricing is per completed PA, roughly $1.50–$2 including status follow-up. Honey reports about one FTE offset per 25 new PAs a day, 80–95% less manual effort, and 99.8–99.9% accuracy, with most practices live in two to three weeks and no onboarding fee.

The honest limit: Honey is provider-side and doesn't render payer decisions, and it's newer than some names here — buyers who weight tenure should ask for references at their size. Practices that want medication PA worked and chased end to end across every payer, inside their EHR, are the best fit.

2. Tandem (Forus) — best for free point-of-prescription PA

Tandem, through Forus, automates medication PA from the prescription written in the EHR — generating the form, submitting, following up, and handling appeals, plus patient-assistance enrollment — and it's free to providers and patients, funded through pharma partnerships. It reached a reported $137 million in funding and a $1 billion valuation in early 2026, with strong adoption in GI, dermatology, and rheumatology.

Forus does medication PA and only medication PA, and its pharma-funded model ties its economics to drug access, which buyers should weigh against a neutral, practice-paid tool. Best for specialty practices with heavy biologic volume that want medication PA at no software cost.

3. Develop Health — best for coverage and PA at prescribing

Develop Health is a GenAI platform that predicts a drug's coverage, cost, and requirements at the moment of prescription, then automates benefit verification, the PA, and payer follow-up, auto-filling forms from EHR data. It raised $14.3 million in 2025 and is expanding EHR and PBM integrations.

It concentrates on the pharmacy benefit, so practices needing medical or imaging PA cover that elsewhere, and its value is highest where prescribers act on coverage signals in real time. Best for groups whose PA burden is concentrated in medications and who want coverage answered at the visit.

4. SamaCare — best for buy-and-bill drug PA

SamaCare automates prior authorization for medical-benefit drugs — the J-code injectables and infusions a practice buys and bills — on AI trained on more than two million PAs, and reports processing billions of dollars in drug authorizations. It raised a $17 million Series B in 2024.

SamaCare is purpose-built for buy-and-bill, sharp there and silent on retail pharmacy ePA, and reads more as an AI-accelerated workflow than a fully autonomous agent. Best for specialty practices (rheumatology, oncology, ophthalmology, dermatology) whose PA pain is buy-and-bill medications.

5. Mandolin — best for specialty-drug access and PA

Mandolin is an agentic platform for specialty-drug administration at infusion centers and specialty pharmacies, where PA submission and follow-up sit inside a wider flow handling benefits investigations, patient cost, co-pay assistance, and 340B pricing. It raised a combined $40 million in 2025 across 700+ clinic locations.

The vertical lock is the consideration: Mandolin is deep on specialty drugs and infusion, not built for general retail-pharmacy PA. Best for infusion centers and specialty pharmacies that want PA inside the full specialty-drug access flow.

6. Silna Health — best for therapy-specialty PA

Silna Health is AI-native for therapy-heavy specialties — ABA, PT/OT, speech, behavioral health — managing recurring authorizations, expirations, payer-specific forms, follow-ups, and appeals, with a pre-submission AI review of clinical docs. It raised $27 million and reports supporting 150,000+ patients.

Silna is tuned to recurring therapy authorizations rather than retail or buy-and-bill drug PA, so the fit is specific. Best for ABA, PT/OT, speech, and behavioral-health organizations.

7. Humata Health — best for touchless PA across drugs

Humata Health automates PA across specialty drugs and medical procedures for both providers and payers, with AI policy matching, automated statusing, and gold-carding, aiming at 90% touchless authorizations. It grew out of Olive AI's PA business and raised about $25 million in 2024.

Because it spans drugs and procedures and bridges both sides, Humata's center of gravity is enterprise revenue-cycle teams and health systems, so the fit leans large. Best for health systems and large groups wanting touchless PA across specialty drugs and procedures.

8. Coral AI — best for drafting PAs across intake

Coral AI replaces RPA with AI across the back office, and prior authorization — extracting data, checking eligibility, reasoning over clinical criteria, and drafting the authorization for review — sits alongside its fax and intake workflows. It raised seed funding led by Lightspeed and reports 500,000+ workflows a month.

As a younger, seed-stage company its footprint is still building, and PA output is drafted for human review rather than fired fully autonomously in every case. Best for groups that want AI drafting medication and other PAs as part of a wider intake automation effort.

9. Banjo Health — best for AI PA decisioning for plans and PBMs

Banjo Health is the payer-side counterpart on this list: an AI platform that helps health plans and PBMs manage the medical and pharmacy PA workflow from request through clinical review to appeals, reading from prescriber EHR notes against payer criteria. It's built for the decisioning side of the transaction.

For a practice, that orientation is the catch: Banjo isn't a tool you buy to submit PAs — it's the AI on the other side of your pharmacy requests. Best for health plans and PBMs modernizing their own medication PA and clinical-review workflows.

10. Basys.ai — best for interpretable AI PA for payers

Basys.ai builds AI agents for prior authorization aimed at payers, emphasizing secure, interpretable, and adaptive decisioning across pharmacy and medical benefits, plus provider workflow automation. The interpretability focus is a direct answer to the trust problem around payer PA AI.

Like Banjo, Basys is payer-side, so a practice doesn't deploy it to submit drug PAs — it's decisioning infrastructure for plans. Best for payers and risk-bearing organizations that want explainable AI behind their PA determinations.

How do you choose an AI medication PA tool?

Start with your seat. If you're a practice, the payer-side tools (Banjo, Basys) aren't yours to buy — your shortlist is the provider-side agents that submit and chase. If you're a plan or PBM, the reverse is true, and the question becomes how explainable the decisioning is.

Then match the tool to your drugs. Pharmacy-benefit volume points to Tandem or Develop Health; buy-and-bill specialty points to SamaCare or Mandolin; therapy specialties point to Silna; a mix of drugs and procedures points to Humata. If your PA spans medication, imaging, and procedures, a broad agent that handles all of them — the way Honey Health's does — saves you from stitching point tools together.

Finally, weigh autonomy and integration. Some tools draft while a person submits; others submit and chase to a decision. And anything needing a per-EHR integration carries a hidden tax that agentic browser automation avoids. For the full field including the free ePA rails, see our medication PA software guide.

Frequently asked questions

What is AI medication prior authorization?

AI medication prior authorization uses machine learning or autonomous agents to do drug-PA work once done by hand — reading the chart, assembling clinical justification, submitting the request, and following up. On the provider side it submits and chases; on the payer side it reviews and decides. The two are different products at opposite ends of the same request.

Can AI fully automate a medication PA?

For much of the volume, yes. Agents like Honey Health work routine drug PAs end to end across payer portals and write the result back to the chart, with people handling genuine edge cases and peer-to-peer reviews. How hands-off it gets depends on your payer mix and the drug's documentation, so expect a high touchless rate plus a clean exception lane rather than 100% autonomy.

Is provider-side or payer-side AI better for medication PA?

They serve different buyers. Provider-side AI (Honey Health, Tandem, Develop Health, and most of this list) submits and tracks drug PAs for a practice. Payer-side AI (Banjo, Basys) decides them for a plan or PBM. A practice can't fix its queue with a payer tool, and a plan can't run UM with a provider agent — identify your side first.

How do AI tools handle specialty and buy-and-bill drugs?

Specialty and buy-and-bill drugs carry the heaviest documentation, so tools built for them — SamaCare for buy-and-bill, Mandolin for infusion and specialty pharmacy, Tandem for biologics — handle the clinical detail, while a broad agent like Honey Health works them across payer portals alongside other PA types.

How much do AI medication PA tools cost?

Models vary: Honey Health charges per completed PA (about $1.50–$2); Tandem's Forus is free and pharma-funded; others price by subscription or enterprise contract; payer tools are sold to plans. Normalize every quote to cost per completed authorization at your volume and compare against the loaded staff cost of your drug PAs today.

AI medication PA is two products on opposite sides of the same request. Decide whether you're buying for the practice or the plan, match the tool to your drug mix, and favor the ones that submit and chase rather than just assist — for a practice that wants drug PAs worked end to end across every payer inside its EHR, an agent like Honey Health is the place to start.
