Medicare Part D
Medicare Part D in South Sioux City: 2027 changes
If you take prescription drugs and have Medicare, 2027 continues a Part D structure that's simpler than it was just a couple of years ago. The old "donut hole" is gone, there's a firm ceiling on what you pay out of pocket for covered drugs at the pharmacy, and the plan year moves through three clear phases instead of four.

Key takeaways
- In 2027, Part D plans continue without a "donut hole" and instead move through three phases: deductible, initial coverage, and catastrophic coverage.
- No Part D plan can charge a deductible higher than $700 in 2027, and once your out-of-pocket drug costs hit $2,400 for the year, you pay $0 for covered drugs for the rest of the year.
- A free Medicare Prescription Payment Plan lets any Part D enrollee spread out-of-pocket drug costs into monthly installments instead of paying it all at the pharmacy, though the total amount owed stays the same.
- People with higher incomes—above $109,000 as a single filer or $218,000 filing jointly—may owe an extra IRMAA charge on top of their regular Part D premium, and Social Security will notify them directly if this applies.
South Sioux City, Neb. — What Part D looks like in 2027
Here's how it works, and where South Sioux City residents can go for one-on-one help.
The three phases of Part D in 2027
Every Part D plan — whether it's a standalone drug plan added to Original Medicare or a Medicare Advantage plan that includes drug coverage — follows the same basic path through the year:
1. Deductible phase. You pay the full cost of your covered drugs (at the plan's negotiated price) until you meet the plan's deductible. In 2027, no Part D plan can set a deductible higher than $700. Some plans set a lower deductible, and some waive it for certain drug tiers. 2. Initial coverage phase. Once the deductible is met, you pay a copay or coinsurance for each prescription, and the plan pays the rest. You stay in this phase until your out-of-pocket spending on covered drugs reaches the annual cap. 3. Catastrophic phase. After you hit the out-of-pocket cap, you pay $0 for the rest of the calendar year on covered Part D drugs.
The coverage gap — the old "donut hole" that used to sit between the initial and catastrophic phases — was eliminated starting in 2025. It is not part of the 2027 program.
The $2,400 out-of-pocket cap in 2027
This is the number most people want to know: the Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027. Once your out-of-pocket spending on covered Part D drugs reaches that amount, you're done paying for those drugs for the rest of the year.
A few things to keep in mind:
- The cap applies to covered Part D drugs. Drugs not on your plan's formulary don't count toward it.
- Premiums do not count toward the cap.
- The cap resets every January 1.
For most people who take expensive medications, this is the single biggest change from the pre-2025 rules, when there was no true ceiling.
The Medicare Prescription Payment Plan
Even with the yearly ceiling, some people can face a large pharmacy bill early in the year — especially if a costly drug is filled in January before the deductible is met.
The Medicare Prescription Payment Plan is a free option that lets you spread your Part D out-of-pocket costs across the calendar year in monthly installments, instead of paying the pharmacy in one lump at pickup. You still pay the same total amount; the plan just smooths the timing. Any Part D enrollee can opt in through their drug plan. It's worth asking about if a big January refill would be hard to absorb.
What this looks like in Dakota County
South Sioux City sits in Dakota County, and Medicare plan availability is set at the county level. That means the menu of standalone Part D plans and Medicare Advantage plans with drug coverage available to you is the Dakota County menu — the same one offered in Jackson, Emerson, and the rest of the county.
The rules above are federal and apply to every Part D plan in every county: the $700 maximum deductible in 2027, the $2,400 out-of-pocket cap in 2027, and the three phases. What varies plan to plan is the specific deductible amount (up to that federal max), the formulary (which drugs are covered and on what tier), the pharmacy network, and the monthly premium.
A note on higher-income enrollees (IRMAA)
Most people pay the standard Part D premium set by their plan. If your income is above $109,000 as a single filer (or $218,000 filing jointly) based on your most recent tax return on file with Social Security, you may owe an Income-Related Monthly Adjustment Amount (IRMAA) on top of your Part D premium. Social Security notifies you directly if this applies.
Key dates to remember
- Annual Enrollment Period: October 15 – December 7. This is when you can join, switch, or drop a Part D or Medicare Advantage plan for the following year.
- Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in a Medicare Advantage plan, you can switch to another MA plan or return to Original Medicare (and add a standalone Part D plan) during this window.
If your drugs, doctors, or pharmacy change — or if your plan sends an Annual Notice of Change with different costs for 2027 — the fall window is the time to review.

How Medicare Part D works in 2027
The old coverage gap (“donut hole”) was eliminated as of 2025 (three phases now). There’s a hard yearly cap on what you pay out of pocket for covered drugs — $2,100 in 2026 and $2,400 in 2027 — and you can spread those costs across the year with the Medicare Prescription Payment Plan.
