Medicare Supplement

Noblesville guide: pairing Medigap with a Part D plan without triggering the late penalty

NOBLESVILLE, Ind. — If you are turning 65 in Hamilton County, or moving off an employer plan, you may hear the words "Medicare," "Medigap" and "Part D" thrown around like they mean the same thing. They do not.

The three pieces, and how they fit

Here is the plain version. Original Medicare is the federal program — Part A (hospital) and Part B (doctor and outpatient). A Medigap policy, also called a Medicare Supplement, is private insurance that helps pay the deductibles, copays and coinsurance Original Medicare leaves behind. A stand-alone Part D plan is separate private insurance that covers prescription drugs.

You need all three pieces working together if you want Original Medicare plus drug coverage plus help with cost-sharing. Medigap does not do the drug piece — that is the part that trips people up.

Why Medigap does not cover your prescriptions

Medigap policies sold today are not allowed to include prescription drug coverage. Older Medigap plans once did, but federal law changed that in 2006, when Part D began. So if the only coverage you have is Original Medicare and a Medigap policy, your pharmacy costs are on you unless you also enroll in Part D.

That is why most people in Noblesville who choose the Medigap route also sign up for a stand-alone Part D plan at the same time.

The timing that keeps you out of the late penalty

The Part D late enrollment penalty is small but permanent. It gets added to your monthly Part D premium for as long as you have Medicare drug coverage, and it grows the longer you wait.

You avoid the penalty by enrolling in Part D when you first become eligible, or by keeping "creditable" drug coverage in the meantime — that means coverage (often from an employer or union plan) that Medicare considers at least as good as a standard Part D plan.

Key windows to know:

• Initial Enrollment Period: The seven-month window around your 65th birthday — the three months before, your birthday month, and the three months after.
• Special Enrollment Period: If you lose creditable coverage (for example, when you retire), you generally have 63 days to enroll in Part D without a penalty.
• Annual Enrollment Period: October 15 – December 7 each year, when anyone with Medicare can join, switch or drop a Part D plan for the following year.

If you go more than 63 days without creditable drug coverage after your Initial Enrollment Period ends, the penalty clock starts.

What Part D looks like in 2026

Some Part D rules changed recently, and they matter when you are comparing plans.

• The maximum annual deductible any plan can charge is $615.
• Once your out-of-pocket spending on covered drugs hits $2,100 for the year, you pay nothing more for those drugs the rest of the year.
• The old "donut hole" coverage gap was eliminated in 2025. Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the calendar year in monthly payments, at no extra charge, if you would rather not pay large amounts at the pharmacy counter.
• Higher-income enrollees pay an IRMAA surcharge on top of the plan's premium. For 2026, that surcharge kicks in above $109,000 in income for a single filer.

Plan premiums, formularies (the list of covered drugs) and pharmacy networks still vary from plan to plan, so the plan that fits your neighbor may not fit you.

Comparing Part D plans in Hamilton County

Noblesville is in Hamilton County, where stand-alone Part D plans are sold by several private insurers approved by Medicare. The full list of plans available to you depends on your ZIP code.

A useful way to compare them is the Plan Finder at medicare.gov. You enter your ZIP code and your prescriptions, and the tool shows you each plan's estimated yearly cost based on your specific drugs and preferred pharmacy. That is usually a more honest comparison than looking at premiums alone, because a low-premium plan can still be expensive if it does not cover your medications well.
