Yes, there is a law that helps you lower your out-of-pocket costs under Medicare Part D, depending on which drugs you take and whether you have very high drug costs. In 2025, your annual Part D out-of-pocket costs will be capped at $2,000. The amount of the cap will increase in future years based on the rate of growth in annual drug spending under Part D. The law also introduced other changes that took effect starting in 2023 and 2024. Beginning in 2023, cost sharing for insulin was capped at $35 per month per prescription, and you no longer have to pay any cost sharing for adult vaccines covered by your Part D plan, such as the vaccine for shingles. Also beginning in 2023, the price of drugs you take cannot increase more than the rate of inflation from one year to the next.
