Prior authorization isn’t one system.
It’s eight categories, deployed in different combinations across every state.
Industry slices Medicaid programs by enrollment, expansion status, 1115 waivers, or MCO penetration percentage. Auth57 slices them by what actually matters when you need to verify a PA claim: where the canonical source lives, which administrator handles which benefit, and which overlays apply. This is that map.
How each state administers Medicaid prior authorization
A single dominant MCO publishes the canonical prior-authorization-required HCPCS list for the whole state. The richest, cleanest verification target — one URL, one document, statewide coverage.
Multiple Medicaid MCOs operate; UnitedHealthcare Community Plan is one of them and publishes a comprehensive PA-required HCPCS list. The most common operational shape — the UHC PDF is the canonical anchor; competitors fill the rest of the cohort.
Multiple Medicaid MCOs operate but UHC isn't present. Verification depends on state-specific brands — Centene's Peach State or Sunshine, Anthem regionals, Aetna Better Health, Molina. No single anchor.
No managed care contracts. Medicaid is administered directly by the state agency, or via primary-care case management. The state Medicaid provider manual is the canonical source.
Additional rules that apply on top of the primary category
Pharmacy benefit administered centrally — at a state PBM (CA Medi-Cal Rx, OH SPBM) or pulled back into state FFS (NY Medicaid Rx). Drug PA does NOT flow through MCOs in these states.
Live 2026-01-05 in AZ, NJ, OH, OK, TX, WA. The CMS Wasteful and Inappropriate Service Reduction Innovation Model — vendor-administered prior authorization for ~17 specific HCPCS codes in Medicare Fee-for-Service.
State law exempts credentialed providers from PA when they meet a statutory approval-rate threshold (typically ≥90% approvals over 6 months). Texas HB 3459/3812 was the pioneer; CO, DC, DE, GA, HI, IL, IN, KY, LA, MI, MS, NM, VT, WV, WY all have enacted or pending gold-card legislation. The fastest-growing overlay.
The state government runs the canonical prior-authorization aggregator — providers submit PA through one state-administered portal instead of each MCO's own grid. AK (DenaliCare via state divisions), AL, GA (GAMMIS Centralized PA), SD, WY. When this shape applies, the verifier routes PA-list-lookup to the state portal, not the per-MCO subdomain.
Every state’s operational shape
Alaska Medicaid is branded as "DenaliCare"; the CHIP companion is "Denali KidCare". Administered directly by the Alaska Department of Health — Division of Public Assistance handles applications/eligibility, Division of Health Care Services designs the program and manages provider payments. No managed care contracts — confirms the FFS + state_centralized_portal shape classification.
AL Medicaid: NO comprehensive risk-based MCO program — AL is one of a handful of states that remain largely FFS.

What the categories look like in practice
The only state in the country with a single canonical MCO publishing the statewide PA-required HCPCS list: L.A. Care’s CMS-0057-F prior-authorization metrics page. 2,000 HCPCS codes mapped to service categories. Drug PA is carved out to Medi-Cal Rx (Magellan, since 2022) — so any drug claim that appears to require PA at an MCO is structurally routed to the PBM instead.
The compound case. Five Medicaid MCOs (Buckeye, CareSource, Molina, UHC, AmeriHealth Caritas); UHC publishes a 1,479-code PA list. Pharmacy is carved out to the Single Pharmacy Benefit Manager (Gainwell, since 2022) — no MCO handles drug PA. And Ohio is a WISeR pilot state, so Medicare Fee-for-Service medicare_traditional rules on ~17 specific HCPCS codes are also subject to vendor-administered PA, on top of everything else.
Three overlays simultaneously. UHC’s Texas PA PDF (1,336 codes) is the canonical anchor; Superior HealthPlan (Centene), Molina TX, Aetna Better Health, and Driscoll Health round out the MCO landscape. Texas is a WISeR pilot state for Medicare FFS. And HB 3459 (effective 9/1/2021) plus HB 3812 (effective 9/1/2023) create a statutory gold-card exemption: any physician who achieves a 90 percent or greater preauthorization approval rate for a specific service during the prior six months is exempt from PA for that service going forward.
Wyoming Medicaid has no managed care contracts. The state Department of Health administers prior authorization directly via the Wyoming Medicaid provider portal. Until recently, the canonical source was a fiscal-agent subdomain (wyequalitycare.acs-inc.com) which has since been decommissioned — a reminder that for FFS states the data depends on continuous host monitoring more than periodic PDF refreshes. Wyoming is not in the WISeR pilot.
We codify the structural differences between US Medicaid programs so payers, providers, and patients can navigate them.
Auth57 maintains the operational map. The same rules, the same response shape, the same source URLs — whether you’re building a prior-authorization API, a member-facing lookup, or a compliance audit. Talk to us about how the category you care about plays out at every state in your footprint.
