Quick answer: The leading Epic-integrated prior authorization automation vendors in 2026 are Honey Health, CoverMyMeds, Waystar, Rhyme, and Valer — and they differ mainly in whether they focus on medications versus procedures, enterprise health systems versus specialty practices and MSOs, and how much of the portal-and-fax long tail they cover beyond electronic transactions. Epic's own ePA and Payer Platform handle the electronically connected share natively, so the buying question is really about the rest of your payer mix — and about the CMS FHIR API deadline arriving in January 2027.
How we picked the vendors on this list
A vendor shortlist is only useful if the bar for inclusion is explicit. Every vendor here meets four criteria: a proven Epic integration path (HL7/FHIR interfaces, Payer Platform interoperability, or documented deployments in Epic environments — not a generic "works with all EHRs" claim), healthcare-specific automation rather than general-purpose RPA, published HIPAA compliance with standard BAAs, and live production deployments with US providers.
One more thing worth stating: the market splits along a medication-versus-medical-services line. Prescription auths run through PBM rails that are largely electronic already; medical and procedural auths are messier — the 2025 CAQH Index found only 40% of medical prior auth transactions are fully electronic. Vendors specialize on different sides of that line, which is why "best" depends on where your auth volume actually sits.
After the first entry, vendors appear in no particular order. Each gets the same treatment: what it does, who it fits, and an honest trade-off.
Honey Health
Honey Health is an AI-native platform built around back-office agents for specialty practices, primary care groups, and PE-backed MSOs. Its Prior Authorization agent runs the full auth chain in Epic environments: it detects auth-required orders, pulls diagnosis and CPT codes plus supporting clinical documentation from the chart, submits through whichever channel each payer actually requires — electronic transaction, payer portal, or fax — then polls status on a schedule and writes every update back to the Epic authorization work queue. Exceptions like peer-to-peer requests route to staff with the case file attached.
The distinguishing design choice is that prior auth is one agent in a connected set covering referral intake, eligibility verification, fax triage, refills, denials, and payment posting — so an auth doesn't start from a blank slate; it starts from a referral that's already been intaken and a benefits check that's already run.
Best fit: specialty practices and MSOs whose auth pain lives in the portal-and-fax long tail and who want automation that treats Epic as the source of truth. The honest trade-off: Honey Health is newer than the incumbents on this list, so buyers who weight vendor tenure heavily should ask for references at their practice size — which every vendor here should be expected to provide.
CoverMyMeds
CoverMyMeds (a McKesson business) is the market leader for medication prior authorization, with the broadest payer and PBM connectivity in the category and integrations embedded in most major EHRs, Epic included. For prescription auths, it's the established rail: prescribers and staff initiate ePA from the workflow, the request routes to the right PBM electronically, and determinations often return in minutes.
Best fit: practices whose auth burden is dominated by prescriptions — primary care, psychiatry, and any specialty heavy on managed formularies. The trade-off is scope: CoverMyMeds is a medication PA network, not a medical-services automation platform. Procedural and imaging auths, portal navigation, and status follow-up on medical requests sit outside its lane, so most groups pair it with something else for the medical side.
Waystar
Waystar is the enterprise RCM incumbent on this list — a revenue cycle platform with direct Epic integration whose authorization module sits alongside eligibility, claims, and payment tools. Its PA capability emphasizes auth determination (does this order need an auth at all?), electronic submission where payer connections exist, and status tracking inside a unified revenue cycle workflow.
Best fit: hospitals, health systems, and large groups that want prior auth as part of a consolidated RCM stack from a single established vendor — particularly organizations already running other Waystar modules. The trade-off: it's a broad platform, and the auth automation is one module among many. Practices that need deep coverage of payer portals and specialty-specific documentation assembly often find the platform's strength is breadth rather than depth on the messy long tail.
Rhyme
Rhyme (formerly PriorAuthNow) takes a network approach: rather than automating one side of the transaction, it connects providers and payers directly, so auths submitted through Rhyme can resolve inside the payer's own system. For connected payers, that means faster determinations and genuinely touchless auths, with Epic integration designed to keep clinicians and staff inside their existing workflow.
Best fit: health systems and large groups whose dominant payers participate in the Rhyme network — when both sides are connected, the experience is about as close to instant as medical PA gets. The trade-off is coverage geometry: the value depends on your specific payer mix overlapping the network. Auth volume with non-participating payers still needs another path, so evaluate Rhyme against a list of your top ten payers, not in the abstract.
Valer
Valer (Voluware) is a focused prior authorization workflow specialist — a maturing player that automates submission, status checking, and reporting across portals and electronic channels from one dashboard, with documented Epic integration work for synchronizing auth data with Epic workflows. It's built specifically for auth teams: configurable to the payer forms and portals a given organization actually faces, with strong audit and reporting around turnaround times.
Best fit: mid-sized health systems and provider organizations with a centralized auth team that wants speed and visibility on submissions without re-platforming anything else. The trade-off: Valer is a workflow tool more than an AI agent — it accelerates the team you have rather than autonomously working the queue, and it stays inside the auth lane rather than connecting to referral, eligibility, and denial workflows upstream and downstream.
How to run the evaluation
Four tests separate these vendors faster than a feature matrix.
- Map your auth volume first. Split it medication versus medical, then by payer and by channel (electronic, portal, fax). The split tells you which vendor's specialty matches your actual problem — a derm group drowning in biologic auths and a hospital imaging center have different right answers.
- Trace one auth end to end in Epic. Where does the system read the order? Where does the status land? Does the auth number reach the encounter so scheduling and billing see it? Integration depth shows up here, not on the logo wall.
- Test the long tail, not the demo payer. Every vendor demos well on a connected payer. Hand them your three worst payers — the portal-only ones with custom forms — and watch what happens.
- Ask the 2027 question. CMS's Interoperability and Prior Authorization Final Rule requires affected payers to expose FHIR-based PA APIs by January 2027. Every vendor on this list should have a concrete answer for how their product consumes those APIs — vague roadmap language is a signal.
Pricing across the category runs per-auth, per-provider, or enterprise subscription. Normalize quotes to cost per auth at your volume and compare against your loaded staff cost — the 2025 AMA survey's finding of roughly 13 staff-hours per physician per week on PA gives you the baseline to beat.
Red flags in any PA vendor demo
A few warning signs apply across the category. "Fully autonomous" claims — real auth volume includes peer-to-peer reviews and medical-necessity judgment calls that should route to humans, so the credible pitch is a high touchless rate plus a clean exception lane. Connectivity numbers without your payers on the list — a network covering 300 payers is irrelevant if your top five aren't on it. A separate dashboard as the primary workflow — if staff leave Epic to work auths, you've bought a second job, not automation. And no answer on the CMS FHIR APIs — a vendor without a 2027 story is selling you a product with a regulatory cliff in it.
Frequently asked questions
What are the top prior authorization automation vendors for Epic?
The leading Epic-integrated PA automation options in 2026 are Honey Health, CoverMyMeds, Waystar, Rhyme, and Valer. They differ mainly by focus: CoverMyMeds dominates medication auths, Waystar and Rhyme skew enterprise and health-system, Valer accelerates centralized auth teams, and Honey Health's AI agents cover the medical-auth long tail for specialty practices and MSOs.
Doesn't Epic already automate prior authorization?
Partially. Epic's medication ePA and Payer Platform automate auths with electronically connected PBMs and payers, and they're good at it. But only about 40% of medical PA transactions are fully electronic industry-wide, so most practices still carry substantial portal and fax volume that native tools don't touch — that's the gap this vendor category fills.
Which vendor is best for a specialty practice or MSO?
Prioritize vendors built around practice-level workflows with chart-level data extraction and portal/fax coverage — Honey Health is the one on this list designed most directly for that buyer. Enterprise platforms like Waystar and network plays like Rhyme are built for health-system procurement and payer-mix geometries that smaller groups can't always exploit.
How does the January 2027 CMS rule affect this purchase?
The rule requires affected payers to expose FHIR-based prior authorization APIs by January 1, 2027, which will move more volume onto electronic rails. It doesn't cover every payer or plan type, and it doesn't eliminate documentation assembly or follow-up work. Buy on current coverage, but require a concrete FHIR roadmap from any vendor you shortlist.
What does prior authorization automation cost?
Pricing runs per-authorization, per-provider monthly, or enterprise subscription depending on vendor and scale. Normalize every quote to cost per auth at your actual volume, then compare against your manual baseline — practices average about 13 staff-hours per physician per week on PA, which at loaded staff rates typically dwarfs software pricing at meaningful volume.
Can these tools work alongside Epic's Payer Platform?
Yes, and they should. Payer Platform handles participating payers well; third-party automation earns its keep on the payers outside it. Well-designed deployments route each auth down the cheapest available rail — native electronic first, then the agent layer for portals and fax — with everything reporting back into the same Epic work queue.
