Your Retiree Drug Plan Is Being Graded Against a Tougher Standard in 2027

The test that decides whether your retiree drug coverage counts as good as Medicare’s has been rewritten, and the standard went up.

CMS finalized the change on April 2 in its contract year 2027 rule. Employers have used a simplified determination method dating to 2009 to certify that a retiree drug plan is at least as generous as Part D. That method is retired. For 2027 and beyond, employers outside the retiree drug subsidy program must use either a revised simplified method or a full actuarial determination.

The Threshold Moved

The share of expected prescription drug costs a plan must cover rises from 72 percent in 2026 to 73 percent in 2027, according to an analysis by Risk Strategies. CMS projects the figure will reach 75 percent by 2030 and stabilize there.

One percentage point sounds like nothing. It is not nothing to a plan that was already sitting near the line, and it is applied through a test that has itself been replaced.

Why the Answer Matters

Coverage that meets the standard is called creditable. If yours is creditable, you can stay on your employer or retiree plan without penalty and pick up Part D later.

If it is not creditable and you go without Part D coverage for an extended stretch, Medicare charges a late enrollment penalty when you eventually sign up. That penalty is not a one-time fee. It stays attached to your premium for as long as you hold Part D coverage.

So the question of whether your plan passed is not paperwork. It determines whether waiting costs you anything.

Who Stops Getting a Letter

One change works in the other direction. Beginning in 2027, account-based arrangements are excluded from the notice requirement entirely: health reimbursement arrangements, including individual coverage HRAs, plus flexible spending accounts and health savings accounts.

If your drug coverage runs through one of those, no notice is coming, and its absence does not mean anything went wrong.

What to Do

Employers send notices of creditable or non-creditable coverage ahead of Medicare’s open enrollment period. Find yours, read which of the two words it uses, and if it says non-creditable, treat the Part D decision as time-sensitive rather than optional.
