The 2026 Medicare Part D Out-of-Pocket Cap Is $2,100
Covered Part D drug spending by the member is capped for 2026, and the Medicare Prescription Payment Plan can spread—not reduce—monthly costs.
The short version: After a person reaches the $2,100 annual out-of-pocket threshold for covered Part D drugs in 2026, the plan generally charges no additional cost sharing for those covered drugs for the rest of the year.
Who should pay attention
People with Medicare Part D coverage, including drug coverage inside a Medicare Advantage plan.
