The pharmacy carve-out: when the state takes the checkbook back

Every state Medicaid program decides who actually cuts the check to the pharmacy. Most delegate it — to managed-care plans and the PBMs they hire. A few states reversed course and took the drug benefit back, paying pharmacies directly at a published price. That reversal is called a carve-out, and it is one of the most consequential — and least explained — choices in pharmacy policy.

Two ways to run a drug benefit

Carved in (the default in most states): the state pays each managed-care plan a fixed monthly premium per member, drugs included. The plan hires a PBM, and the PBM decides — drug by drug, pharmacy by pharmacy, under contracts nobody outside can read — what the pharmacy actually gets paid. The state is two layers removed from the pharmacy counter.

Carved out: the state pulls the pharmacy benefit out of those contracts entirely. Members may still be in a health plan for doctors and hospitals, but when they fill a prescription, the state itself pays the pharmacy, claim by claim, at its published formula: the drug's acquisition cost plus a professional dispensing fee (roughly $8–12 in every state). California did this in 2022 (Medi-Cal Rx), New York in 2023 (NYRx), West Virginia back in 2017 — and Tennessee got the same effect a different way, routing every claim through one state-contracted PBM at published terms since 2020.

Why pharmacies care so much

1. The published fee becomes real money.A state's published dispensing fee legally binds only its own fee-for-service program — managed-care PBMs owe pharmacies whatever their private contracts say, which is often a fee of pennies to a couple of dollars. A carve-out puts every prescription back under the published formula. Our 50-state fee surveyshows the difference plainly: Florida's plans report about half the published fee per generic prescription, while California's carved-out filings land on the published fee almost to the dollar.

2. Spread pricing becomes structurally impossible. Spread pricing — a PBM charging the program one price and paying the pharmacy a lower one — needs a middleman between payer and pharmacy. A carve-out removes the middle. Ohio's 2018 state audit measured $224.8 million in one year of spread; Kentucky's 2019 report found $123.5 million; West Virginia carved out in 2017 and credits the move with saving $54 million in its first year. (The audit documents are linked from the fee survey.)

3. No games only a middleman can play.Florida's claims analysis documented PBMs steering prescriptions to their own affiliated pharmacies at premium prices while independents averaged below-cost reimbursement. When the state pays every pharmacy the same published formula, there is no mechanism for paying your own pharmacy more than your competitor.

4. Predictability — which for a small pharmacy is survival. Under carved-in PBM contracts, an independent pharmacy fills a prescription without knowing whether it nets $8 or loses $3. Under a carve-out, every fill pays acquisition cost plus the fee. A pharmacy can staff and plan against that. (More on why this matters in the community pharmacy guide.)

The honest other side

A carve-out is not free. The state takes on the pharmacy work itself — formulary, claims processing, prior authorization. Managed-care plans argue it fragments care by splitting drugs from medical management. And New York's carve-out was delayed two years largely because 340B safety-net clinics lost contract-pharmacy revenue the old arrangement generated. States that carve out also pay more per prescription at the counter— the bet, which West Virginia's and Kentucky's numbers support, is that eliminating the spread saves more than the fee costs.

The spectrum of state answers

The carve-out is the strongest of several designs states use to put themselves back in the payment path:

• Full carve-out: California, New York, West Virginia — the state pays pharmacies directly.
• Single state-contracted PBM: Tennessee, Ohio, and Kentucky — managed care stays, but one pass-through PBM handles every claim at published or contracted transparent terms.
• Floor laws (carve-out lite): Louisiana wrote the fee-for-service rate into statute for its MCOs; Mississippi mandated the FFS formula outright — its filings match the published fee to the penny; Michigan, North Carolina, and Nebraska have narrower floors; and bills in South Carolina, Illinois, and New Jersey would follow.
• Never carved in: eleven states, from Wisconsin to Maine, never put pharmacy into managed care at all.

The one-sentence version: a carve-out moves the pharmacy from the bottom of a private negotiation it cannot see into a published price list it can hold the state to. That is why pharmacy associations push for carve-outs — or the floor laws that imitate them — in nearly every state where the survey shows a gap.
