CMS has finalized new Part D creditable coverage requirements for plan years beginning January 1, 2027:
• The existing Simplified Determination Method will be retired.
• The Revised Simplified Determination Method will require plans to cover an average of at least 73% of participants’ prescription drug expenses.
• Plans may instead use a full actuarial determination.
The threshold change from 72% in 2026 to 73% in 2027 may appear small. But the determination should not be treated as automatic, especially for groups with lean prescription drug benefits.
If a plan loses creditable status, Medicare-eligible members will need accurate, timely information. Delaying Part D enrollment without creditable coverage can result in late-enrollment penalties.
For brokers, the next step is to identify potentially affected groups before renewal decisions are finalized. Confirm the plan’s status, understand which determination method is being used, and give the employer time to communicate with affected members.
