Last week, the Centers for Medicare and Medicaid Services (CMS) released the list of the first round of prescription drugs chosen for Medicare Part D price negotiations. The 2022 Inflation Reduction Act (IRA) granted CMS the authority to negotiate directly with pharmaceutical manufacturers, establishing a process that will ramp up to include 20 drugs per year and cover Part B medicines by 2029.

The majority of the initial 10 medications, including Eliquis, Jardiance, and Xarelto, are highly utilized across Medicare beneficiaries, treating mainly diabetes and cardiovascular disease. But three of the drugs (Enbrel, Imbruvica, and Stelara) are very high-cost drugs used by fewer than 50k beneficiaries to treat some cancers and autoimmune diseases.

Together the 10 drugs cost Medicare about $50B annually, comprising 20 percent of Part D spending. Drug manufacturers must now engage with CMS in a complex negotiation process, with negotiated prices scheduled to go into effect in 2026. 

The Gist:

Most of the drugs on this list are not a surprise, with the Biden administration prioritizing more common chronic disease medications, with large total spend for the program, over the most expensive drugs, many of which are exempted by the IRA’s minimum seven-year grace period for new pharmaceuticals.

However, pharmaceutical companies are threatening to derail the process before it even begins. Several companies with drugs on the list have already filed lawsuits against the government on the grounds that the entire negotiation program is unconstitutional. 

While President Biden is already touting lowering drug prices as a key plank of his reelection pitch, it will take years before these negotiations translate into lower costs for beneficiaries and reduced government spending. There also may be adverse unintended consequences, as drug companies may raise prices for commercial payers while increasing rebates to stabilize net prices, leading to higher costs for some consumers. 

Still, it’s a step in the right direction for the US, given that we pay 2.4 times more than peer countries for prescription medications.
