Medicare in Iowa City: Key 2027 Dates

Iowa City, Iowa — If you're turning 65 in Iowa City, still on the job, or just trying to keep your Medicare coverage in shape for 2027, the calendar matters more than almost anything else. Miss a window and you could wait months to fix it — sometimes with a penalty attached.

Johnson County had 31 Medicare Advantage plans available for 2026, offered by 8 carriers, according to the CMS Medicare Plan Finder. The 2027 lineup is in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder. That's a lot to look through, which is exactly why knowing when to look is half the battle.

The Fall window: October 15 – December 7

This is the Annual Enrollment Period, often called AEP or the fall Open Enrollment. It's the one most people know. During these dates you can:

• Join, switch, or drop a Medicare Advantage plan.
• Join, switch, or drop a Part D prescription drug plan.
• Move from Original Medicare to Medicare Advantage, or the other way around.

Whatever you pick takes effect January 1, 2027. If December 7 passes and you did nothing, your current plan generally rolls over — assuming it's still being offered. That's an important "if." Plans can change their benefits, pharmacy networks, or drug lists each year, so a rollover is not the same as staying put.

The January-to-March window: a second chance, with limits

The Medicare Advantage Open Enrollment Period runs January 1 through March 31. It's narrower than the fall window and it has rules:

• You must already be enrolled in a Medicare Advantage plan on January 1.
• You get one change. You can switch to a different Advantage plan, or drop yours and return to Original Medicare (and add a stand-alone Part D plan if you go that route).
• If you're in Original Medicare on January 1, this window is not for you.

This period is a safety net, not a do-over for every decision.

Turning 65: your Initial Enrollment Period

Your Initial Enrollment Period is a seven-month window: the three months before your 65th birthday month, your birthday month itself, and the three months after. Signing up during the three months before your birthday helps coverage start the month you turn 65.

Miss it entirely and you may face a Part B late enrollment penalty that sticks with you for life, plus a wait until the General Enrollment Period (January 1 – March 31) to sign up, with coverage starting the following month.

Still working at 65? The Special Enrollment Period

Plenty of Iowa Citians work past 65 — the University, the hospitals, small businesses, farms. If you have qualifying group health coverage through your job (or your spouse's job), you generally don't have to take Part B right at 65. When that job-based coverage ends, a Special Enrollment Period gives you up to 8 months to sign up for Part B without a penalty, and 63 days to pick up a Part D drug plan.

The rules are strict, though. COBRA and retiree coverage do not count as active employer coverage for this purpose. If you're not sure whether your plan qualifies, call your benefits administrator before your 65th birthday, not after.

What happens if you miss a deadline

Missing windows has real consequences:

• Miss your Initial Enrollment Period for Part B — expect a lifetime penalty of 10% for each full 12 months you could have had it but didn't, and a wait for the General Enrollment Period.
• Miss Part D when you were first eligible — a smaller monthly penalty may be added to your drug plan premium for as long as you have Part D.
• Miss the December 7 AEP deadline — you'll generally be locked into your current setup for the year, unless you qualify for a Special Enrollment Period (moving, losing other coverage, qualifying for Extra Help, and a few others).

How the dates fit together

Think of it as three layers:

1. Your personal window (Initial or Special Enrollment) — tied to your age or your job. 2. The fall window for everyone (Oct. 15 – Dec. 7). 3. The January–March window for people already in Medicare Advantage.

A quick program note: the Part D annual out-of-pocket cap on covered drugs is $2,100 in 2026 and $2,400 in 2027, and the maximum Part D deductible is $615 in 2026 and $700 in 2027. The old coverage gap remains gone. The optional Medicare Prescription Payment Plan lets you spread drug costs across the year in monthly amounts. None of that changes the deadlines above — but it may change how you weigh your options once you're in a window.
