This April through June under the Inflation Reduction Act, Medicare will reduce the coinsurance amount for 27 Part B prescription drugs from 20% to somewhere between 10% and 19.9%, depending on the drug, the Centers for Medicare & Medicaid Services announced today.
The IRA requires drug companies to pay rebates to Medicare when prices for certain single-source and biosimilar prescription drugs covered under Part B increase faster than the rate of inflation. These 27 drugs are among the first rebatable drugs under the law. Part B drugs impacted by a coinsurance adjustment may change quarterly. For more information, see the CMS fact sheet.
