Medicare Part D in 2026: The $2,100 Out-of-Pocket Threshold

How the redesigned benefit works

The Inflation Reduction Act redesigned the standard Part D benefit beginning in 2025. In 2026 the benefit continues without the former coverage-gap phase, and an enrollee with covered Part D drug spending that reaches the annual out-of-pocket threshold generally has no additional cost sharing for covered Part D drugs for the remainder of the year.

Medicare Prescription Payment Plan

Part D plans continue to offer the Medicare Prescription Payment Plan. The option can spread an enrollee’s out-of-pocket prescription costs across monthly payments during the plan year. It changes timing—not the total amount owed—and is not automatically the best choice for every enrollee.

What employers and advisors should watch

• Keep retiree and benefits communications tied to the correct plan year.
• Avoid reusing the 2025 $2,000 cap in 2026 materials.
• Distinguish Medicare Part D benefit changes from employer creditable-coverage notice obligations.
• Direct individual enrollment and cost questions to Medicare, the plan, or a qualified benefits advisor.
