Medicare Part D

Original Medicare + Medigap vs. Advantage in West Fargo

# Original Medicare with a Medigap plan vs. Medicare Advantage: how to think it…

WEST FARGO, N.D. — If you're turning 65 or thinking about a change during Medicare's fall enrollment window, the biggest decision isn't which plan has the flashiest brochure. It's the structure underneath. Do you want Original Medicare paired with a Medigap policy, or do you want a Medicare Advantage plan? These two paths work differently, and switching later isn't always simple. Here's a plain-English walk-through to help you avoid the most common mistakes.

Two very different ways to get the same Medicare

Everyone eligible for Medicare gets the same core program from the federal government: Part A (hospital) and Part B (doctor and outpatient). What's different is how you receive those benefits.

• Original Medicare + Medigap + Part D. You use your red-white-and-blue Medicare card. You can see any doctor or hospital in the U.S. that accepts Medicare. A separate Medigap (Medicare Supplement) policy helps pay the out-of-pocket costs Original Medicare leaves behind, like coinsurance and deductibles. A stand-alone Part D plan handles prescriptions.
• Medicare Advantage (Part C). A private plan, approved by Medicare, delivers your Part A and Part B benefits — usually with a network of doctors and hospitals. Most Advantage plans also include Part D drug coverage and may include extras like dental, vision, or hearing. You use the plan's card instead of your Medicare card.

Both are legitimate paths. Neither is "better" in the abstract. What fits depends on your health, your doctors, your budget, your travel habits, and how you feel about paperwork versus rules.

What you're really trading

Think of the choice as trading two things against each other: flexibility and predictability.

• Original Medicare with a Medigap plan tends to offer more flexibility — broad access to providers nationwide — in exchange for paying a monthly Medigap premium on top of Part B.
• Medicare Advantage tends to offer more predictability at the front end — one card, often lower monthly premiums, an annual out-of-pocket maximum — in exchange for staying inside a network and following plan rules like prior authorization and referrals.

Neither trade is wrong. But it's worth being honest with yourself about which one you'll be happier living with.

The Medigap timing trap

This is the mistake we see most often, so read this section twice.

When you first enroll in Part B at 65, you get a six-month Medigap Open Enrollment Period. During that window, insurers must sell you any Medigap policy they offer at their best available rate, regardless of your health.

After that window, in most states, Medigap insurers can use medical underwriting — meaning they can ask health questions and turn you down or charge more based on your history. So if you start on Medicare Advantage and later decide you'd rather have Original Medicare + Medigap, getting into a Medigap policy may not be guaranteed. That's a one-way door in a lot of cases, and people don't realize it until they try to walk back through.

North Dakota follows federal Medigap rules on this point. If you're in West Fargo and weighing your first Medicare choice, talk this through carefully before you decide.

What's changing under Part D in 2027

Drug coverage is part of both paths — built into most Advantage plans, added separately alongside Original Medicare. A few program-level numbers worth knowing as you compare 2027 options:

• Out-of-pocket cap on covered Part D drugs: $2,100 in 2026 and $2,400 in 2027.
• Maximum Part D deductible a plan can charge: $615 in 2026 and $700 in 2027.
• The old "donut hole" is gone — Part D now has three phases (deductible, initial coverage, catastrophic).
• The Medicare Prescription Payment Plan lets you spread your drug costs across the year in monthly installments instead of paying big bills at the pharmacy counter. It's optional and free to opt into.
• IRMAA — the income-related surcharge on Part B and Part D — starts above $109,000 for a single filer in 2026 (higher for joint filers).

These figures apply the same way whether your drug coverage comes through a stand-alone Part D plan or is bundled into a Medicare Advantage plan.

Plan availability in Cass County

West Fargo is in Cass County, and Medicare plan availability — how many Advantage plans and stand-alone Part D plans are offered — is set at the county level, not the city level. That means every West Fargo resident sees the same menu as their neighbors elsewhere in Cass County.

To see the current list for your ZIP code, use the Plan Finder at medicare.gov or call 1-800-MEDICARE. You can filter by your prescriptions and preferred pharmacy, which matters more than most people expect.

Dates to keep on the fridge

• Oct. 15 – Dec. 7: Annual Enrollment Period. Anyone with Medicare can join, switch, or drop a Medicare Advantage or Part D plan. Changes take effect Jan. 1.
• Jan. 1 – Mar. 31: Medicare Advantage Open Enrollment. If you're already on an Advantage plan, you can switch to a different one or return to Original Medicare (and pick up a Part D plan).
• Your Initial Enrollment Period around your 65th birthday — and that six-month Medigap window that starts when your Part B begins.

Missing these dates is another common, avoidable mistake.
