Part D Premiums and Cost Sharing in 2027
The average monthly premium for Medicare Part D coverage in stand-alone prescription drug plans (PDPs) will increase to $51 in 2027, up 50% from $34 in 2026, if current enrollees don’t switch into lower-premium plans during the open enrollment period. That is more than five times higher than the drug coverage premium in Medicare Advantage plans that offer Part D coverage, which is projected to average $9 per month in 2027. Most Part D enrollees also will face a deductible of several hundred dollars for drug coverage in 2027.
