What Are the Implications of the Recent Elimination of the Medicaid Prescription Drug Rebate Cap?


As of January 1, 2024, the American Rescue Plan Act (ARPA) lifted the cap at the overall quantity of rebates that Medicaid may just gather from producers who lift drug costs considerably through the years. Expecting the implementation of this coverage, drug producers have made more than a few adjustments letting them steer clear of larger rebates as a consequence of the lifting of the cap. Fresh adjustments that experience garnered consideration come with value cuts for insulin, used to regard diabetes, and the discontinuation of Flovent, a ceaselessly used bronchial asthma inhaler. Whilst the insulin value cuts had been portrayed by way of drug producers as a step to strengthen affordability, they’ll actually be earnings maximizing efforts in line with the adjustments within the Medicaid rebate components. This coverage watch explains what the rebate cap is, examines what number of medicine may well be impacted, and explores the results of new producer responses on Medicaid systems and enrollees.

What’s the rebate cap?

ARPA eradicated the prohibit on Medicaid drug rebates producers pay beginning January 1, 2024. Below the Medicaid Drug Rebate Program, drug producers supply rebates to the government and states in change for Medicaid protection in their medicine. The rebate quantity contains two major parts: a rebate according to a share of reasonable producer value (AMP) (or the variation between AMP and “best price,” whichever is bigger) and an inflationary element to account for value will increase. The AMP is the cost charged by way of drug producers to wholesalers. As a result of the inflationary element, the calculated rebate on a drug whose value will increase briefly through the years might be more than the AMP for that drug. On the other hand, the entire rebate quantity were capped at 100% of AMP since 2010. Consequently, producers who hit the rebate cap didn’t face further Medicaid rebates in the event that they persisted to extend costs. Fresh KFF research discovered rebates reduced Medicaid spending on prescribed drugs by way of over part every yr from fiscal yr 2017 thru 2022 (Determine 1). On the other hand, ARPA, enacted in March 2021, eradicated the 100% AMP cap on Medicaid drug rebates as of January 1, 2024.

The lifting of the rebate cap is anticipated to have a considerable impact on model medicine, particularly the ones medicine that experience already hit the rebate cap or have value will increase a lot sooner than inflation through the years. A prior KFF analysis of gross prescription drug spending in Medicaid discovered that greater than a 3rd (34%) of substances had value will increase above inflation between 2015 and 2019, even though now not most of these medicine hit the rebate cap. Medication with fewer medicine of their healing elegance had been much more likely to have will increase above inflation. Different research has proven that round 15%-20% of all model medicine have reached the cap. Additional, contemporary MACPAC analysis discovered a small percentage of all medicine (4.7%) reached the rebate cap in FY 2020 however estimates overall rebates would equivalent 130.8% of gross spending on the ones medicine with out the rebate cap.

What are the results of lifting the rebate cap?

Based on the removing of the rebate cap, some drug corporations are decreasing drug costs or discontinuing medicine in choose of decrease priced possible choices to steer clear of paying further Medicaid rebates. After years of accelerating checklist costs, insulin producers have lately cut prices of a few insulin merchandise as much as 85%. The lifting of the rebate cap used to be a big contributor to this reaction; analysis has shown insulin producer Eli Lilly used to be anticipated to pay $430 million and Novo Nordisk $350 million in more rebates to Medicaid in 2024. Whilst those insulin value decreases are slightly huge, drug producers won’t in reality see lowered revenues given the rebate bills they’re going to steer clear of as outcome. Every other drugmaker GSK is reducing costs of a few products in addition to discontinuing their model medicine Flovent HFA and Flovent Diskus, ceaselessly used bronchial asthma inhalers, and can as a substitute promote a generic selection, with a decrease checklist value. It continues to be noticed what number of extra medicine will see value cuts or be discontinued, and it may be difficult to expect which medicine or producers shall be maximum suffering from the coverage trade as knowledge on drug AMPs and rebates is recently proprietary. On the other hand, an research of 2017 knowledge discovered 25 medicine, maximum of that have been for diabetes remedy, accounted for 85% of rebates lowered by way of the cap. Producers might also respond in different ways, comparable to by way of elevating release costs.

Whilst beneath present legislation Medicaid should duvet the vast majority of a rebating producer’s FDA licensed medicine, if a specific drug is discontinued, Medicaid enrollees might revel in some administrative demanding situations when looking to get right of entry to possible choices. As a result of Medicaid should duvet the vast majority of a taking part producer’s FDA licensed medicine, Medicaid would duvet a rebating producer’s new generic (as on the subject of Flovent). On the other hand, states can use an array of payment strategies and usage controls to manage pharmacy expenditures, together with liked drug lists and prior authorization (PA) insurance policies connected to medical standards, which is able to have an effect on get right of entry to. There might be some administrative demanding situations Medicaid enrollees might wish to navigate relying at the state or well being plan. People might wish to transfer prescriptions to another product on the most well liked drug checklist or get approval to make use of a non-preferred drug which might result in delays in getting access to prescriptions. Bronchial asthma incidence is higher for other people with Medicaid when put next with non-public insurance coverage, and kids is also uniquely impacted because the Flovent inhaler made it conceivable for small children to make use of the medicine. Producer responses might also lead to changes in out-of-pocket prices for business and uninsured sufferers; alternatively, Medicaid enrollees most often pay very little copays for prescribed drugs, together with for insulin.

Lifting the rebate cap used to be anticipated to cut back Medicaid spending, even though the extent of financial savings is dependent on how drug corporations reply in addition to impacted by way of later provisions within the Inflation Aid Act (IRA). When enacted, getting rid of the rebate cap used to be projected by way of the Congressional Price range Place of work to cut back federal spending by way of greater than $17 billion over ten years. On the other hand, value financial savings beneath adjustments to the rebate cap shall be dependent on producer responses to the trade in coverage. Additional, the IRA, handed in 2022, calls for drug corporations to pay a rebate to the federal government if drug costs upward push sooner than inflation in Medicare beginning in 2023 (this requirement already exists in Medicaid). The Medicare inflation-related rebates will imply slower enlargement in drug costs through the years, resulting in decrease Medicaid inflation-related rebates and increased Medicaid drug spending. The lifting of the rebate cap magnifies the effects of the Medicare inflation-related rebates within the IRA on Medicaid.

States and controlled care plans might modify their liked drug lists (PDLs) because the panorama shifts in line with the lifting of the rebate cap. Rebates are normally higher for model call medicine, so states occasionally choose model medicine with top rebates over generics. As an example, whilst this can be moving, insulin usage in Medicaid has been in large part concentrated amongst brand-name medicine most likely because of top rebate quantities. As costs of brand name medicine trade and generic medicine come available on the market, states might modify their PDLs to maximise financial savings. As an example, Massachusetts Medicaid has got rid of the PA requirement for 3 model possible choices for Flovent and has added a PA requirement for the generic Flovent. The state will permit the usage of the generic Flovent with out PA till March to clean the transition for participants. New York Medicaid has made a similar trade. States regularly take motion like this to include Medicaid prescription drug prices, with over two-thirds of states in KFF’s annual survey of state Medicaid systems reporting new or expanded projects to include prescription drug prices, together with important PDL or rebate adjustments.
