Medicare Part D

Delaying Part D in Downey? The notice from your plan is what protects you

DOWNEY, Calif. — If you're turning 65 in Downey but still working, or you're a veteran using the VA pharmacy, you've probably wondered whether you need to sign up for Medicare Part D right away. The short answer: not always. If your current drug coverage is considered "creditable," you can put off Part D without paying a lifetime penalty later. The proof is a plain piece of paper — the Notice of Creditable Coverage — and it's worth holding on to.

Key takeaways

  • If you have drug coverage through an employer, union, the VA or TRICARE, it may be "creditable," meaning you can delay Part D without a late-enrollment penalty.
  • Plans are required to send a Notice of Creditable Coverage each year, usually before October 15 — keep it in a safe place.
  • Once your other drug coverage ends, you generally have 63 days to enroll in Part D to avoid a penalty.
  • For personal help in Downey, call 1-800-MEDICARE or reach California's SHIP program (HICAP) for free counseling.

What "creditable" drug coverage means

Medicare uses the word "creditable" to describe drug coverage that pays, on average, at least as much as a standard Part D plan would. If your coverage meets that bar, Medicare treats it as good enough to stand in for Part D. That means you can stay on your current plan and skip Part D for now, with no penalty when you eventually enroll.

Common examples of creditable coverage include:

Not every workplace plan is creditable — some smaller employers or high-deductible plans may not clear the bar. That's exactly why the notice matters.

The notice: what it is and why you want to keep it

Every year, plans that offer drug coverage are required to tell you in writing whether that coverage is creditable. This is called the Notice of Creditable Coverage (or, if it isn't creditable, a Notice of Non-Creditable Coverage). You should receive one:

Tuck it into a folder with your other Medicare paperwork. If you ever need to enroll in Part D later, Medicare may ask you to prove you had creditable coverage. Without that proof, you could be charged a late-enrollment penalty — and it's permanent, added to your Part D premium for as long as you have the coverage.

How the late-enrollment penalty works

The Part D late-enrollment penalty is calculated by counting the number of full months you went without creditable drug coverage after you were first eligible for Medicare. That count is multiplied by 1% of the national base beneficiary premium and added to your monthly Part D premium going forward.

A short gap — say, a few weeks between jobs — usually won't trigger it. But if you go 63 days or more in a row without creditable coverage and don't sign up for Part D, the clock starts.

When to actually enroll in Part D

If you're keeping creditable coverage past 65, you generally don't need to do anything about Part D right away. But once that coverage ends — you retire, leave a job, lose VA eligibility, or a spouse's plan drops you — you'll want to act quickly.

You have a Special Enrollment Period of 63 days after your creditable coverage ends to sign up for a Part D plan or a Medicare Advantage plan that includes drug coverage. Miss that window and you may have to wait until the next Annual Enrollment Period (October 15 – December 7) and face the penalty.

A few program figures worth knowing when you do enroll:

A Downey snapshot

Downey is in Los Angeles County, where retirees have a large number of stand-alone Part D and Medicare Advantage drug plans to choose from when they're ready to enroll. County-level availability is public information posted on medicare.gov's Plan Finder each fall.

For veterans in the area using the West Los Angeles VA or clinics closer to Downey, VA drug coverage is considered creditable. Many retirees choose to stay with VA and skip Part D entirely — that's allowed, as long as you understand you'd need Part D (or a Medicare Advantage plan with drug coverage) to fill prescriptions at a regular retail pharmacy without paying full price.

Good to know

Frequently asked questions

Do I have to enroll in Part D at 65 if I'm still working?
No. If your employer's drug coverage is creditable, you can delay Part D without a penalty for as long as you keep that coverage. Ask your HR department for the annual Notice of Creditable Coverage and keep it with your records.
Is VA drug coverage considered creditable for Medicare?
Yes. VA prescription drug benefits are creditable, so veterans who use VA pharmacies do not need to enroll in Part D to avoid a penalty. Some veterans still choose to add Part D so they can use community pharmacies — that's a personal decision.
What happens if I lose my notice?
Contact the plan that provided the coverage — your employer's benefits office, the VA, TRICARE, or your union — and ask for a replacement letter. You can request one at any time, and you may need it when you eventually enroll in Part D.
How long do I have to enroll in Part D after my other coverage ends?
You generally have 63 days from the date your creditable coverage ends to sign up for a Part D plan or a Medicare Advantage plan with drug coverage. Enrolling in that window avoids the late-enrollment penalty. For the most current rules and to compare plans when you're ready, visit medicare.gov or call 1-800-MEDICARE. Downey residents can also reach California's HICAP counselors for free, local, one-on-one guidance.
