Senate approves PBM transparency package after heated debate over dispensing fee and fiscal impact

The Mississippi Senate on Thursday approved a substitute bill aimed at reforming pharmacy benefit managers (PBMs), sending the measure on to further process after a long, contested floor debate over whether the bill’s reimbursement design would raise health‑plan costs.

Senator Brinda Parks, the floor sponsor of the substitute, framed the bill as a transparency and fairness package for independent and rural pharmacies. Parks described two principal components: a reimbursement benchmark based on a national acquisition cost index (NAK) and a separate dispensing fee intended to reimburse pharmacies for the cost of filling prescriptions. She told the Senate the combination produced a “net savings of $54 million” in Mississippi’s Medicaid program when a similar methodology was used there.

The debate turned sharply on the substitute’s dispensing‑fee language. Opponents, including Senator Kevin England, presented an LBO/DFA analysis — requested on the floor — that said the state plan’s cost exposure could be tens of millions of dollars annually. England told colleagues the fiscal note identified a roughly $34 million annual cost using earlier enrollment figures and said a revised caseload suggested the impact could exceed $50 million. “If we pass this strike‑all amendment, it will cost the state of Mississippi $34 million,” England said on the floor, adding he believed the exposure would be larger based on updated prescription counts.

Senator Sparks, defending the change to the SNAP verification bill earlier in the day, pressed for clarity about how the state’s federal error‑rate exposure had been calculated; several senators noted the larger federal policy context, including pending federal PBM provisions and recent federal legislation.

Sponsors argued the bill would not raise costs for employers overall because greater transparency (NAK‑based reimbursement plus an explicit dispensing fee) would let plan sponsors see actual acquisition costs and negotiate more effectively with PBMs. Parks and other supporters pointed to other states that adopted similar NAK methodologies and said they had not seen the large employer‑side cost increases opponents predicted.

The Senate adopted the substitute strike‑all after floor amendments and a division; the record shows the measure passed by morning roll call. The chamber’s debate left prominent divisions in the record: independent pharmacists and some legislators said reform is necessary to preserve rural access to pharmacies; business and employer‑representative groups warned that a mandated dispensing fee could raise employer premiums and public‑plan costs.

What happens next: the bill’s text — as passed — will be reconciled with the House version if needed. Lawmakers on both sides signaled they intended to continue negotiating technical details in conference or in follow‑up bills. The debate underscored the policy trade‑offs: transparency and predictable local pharmacy revenue vs. potential higher short‑term costs for state employees and employer health plans.
