The $2,000 cap, included in the Inflation Reduction Act (IRA), helps to cap the cost of out-of-pocket prescription drugs for people who are on Medicare Part D starting in 2025. In other words, if you’re on Medicare Part D, you will not pay more than $2,000 a year for out-of-pocket prescription medications.

The $2,000 cap is just one provision in the IRA that helps to lower the costs of prescription drugs for Medicare beneficiaries. The IRA also capped the cost of insulin at $35 per month beginning in 2023, and it makes some recommended vaccines free.
