Denver Medicare at 65: the Initial Enrollment Period

Denver Medicare at 65: the Initial Enrollment Period — plain-language Medicare information for Denver, Colorado.

DENVER — If you're approaching your 65th birthday, the calendar suddenly matters more than you might think. Medicare gives you a one-time, seven-month window called the Initial Enrollment Period (IEP) to sign up — and missing it can mean delayed coverage and lasting late-enrollment penalties.

Here in Denver, thousands of residents cross that milestone every year. The rules are the same across the country, but the first steps you take now can shape your coverage for decades.

What the Initial Enrollment Period actually is

The IEP is your personal, seven-month window to enroll in Medicare when you first become eligible. It includes the three months before the month you turn 65, the month of your birthday, and the three months after. For most people, this is the first — and simplest — chance to sign up for Part A (hospital) and Part B (medical).

If you enroll in the three months before your birthday, your coverage generally begins the first day of your birthday month. Wait until later in your window, and coverage starts the month after you sign up.

Why timing matters more than people expect

Medicare isn't automatic for everyone. If you're already receiving Social Security benefits before 65, you'll likely be enrolled in Part A and Part B automatically. But if you're not — and many people today are working longer and delaying Social Security — you have to take action yourself.

Skip your IEP without other qualifying coverage, and you may face:

• A Part B late-enrollment penalty that can be added to your premium for as long as you have Medicare.
• A Part D late-enrollment penalty if you go 63 or more days without creditable drug coverage.
• A wait until the next General Enrollment Period to sign up, which can leave you uninsured for months.

First steps to take right now

You don't have to figure everything out at once. But a few early moves make the rest easier:

1. Create a My Social Security account at ssa.gov. This is where you'll actually enroll in Medicare online. 2. Check whether you'll be auto-enrolled. If you're drawing Social Security, watch the mail for your red, white, and blue Medicare card. 3. Look at your current coverage. If you have employer insurance, ask your HR department whether it counts as "creditable" and whether you should delay Part B. 4. Decide how you want to get your Medicare. You'll choose between Original Medicare (with the option to add a standalone Part D drug plan and possibly a Medigap policy) or a Medicare Advantage plan that bundles coverage.

What's new for 2027

A few program-level changes are worth knowing as you plan:

• The Part D out-of-pocket cap is $2,100 for 2026, giving prescription users a firmer ceiling on annual drug spending.
• The Part D maximum deductible is $615 in 2026 and $700 in 2027.
• The coverage gap (or "donut hole") has been eliminated as of 2025, replaced by a simpler three-phase design.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the year in monthly installments instead of paying large amounts at the pharmacy counter.
• IRMAA surcharges — the higher premiums for higher-income beneficiaries — start above $109,000 in income for single filers in 2026.

Denver-area context

Denver is in Denver County, where Medicare Advantage and Part D plan availability is determined at the county level. That means the menu of options a Denver resident sees can differ from what a neighbor a few miles away in Jefferson or Arapahoe County sees. When you're ready to compare, use the Plan Finder on medicare.gov and enter your ZIP code so the results match what's actually available where you live.
