CMS announced that the voluntary demonstration for standalone prescription-drug plans will not continue into 2027.

What the record says

In its July 28, 2026 Part D bid-information announcement, CMS said it would discontinue the Part D Premium Stabilization Demonstration at the end of calendar year 2026.

CMS describes the demonstration as voluntary and applicable to standalone prescription-drug plans. Its announcement says 2027 plans return to traditional market conditions.

Practical next step

Check the actual 2027 costs and coverage offered by a plan when comparing options during annual enrollment. The announcement about a demonstration cannot determine your personal premium.

Limits and what is not established

This is an announced policy change, not evidence that every beneficiary’s premium will increase or that a particular plan will disappear. Preliminary bid figures are not substituted for finalized individual plan prices.
