Fullerton at 65: how to time your Medicare sign-up and skip the late penalties

Turning 65 in Fullerton comes with a mailbox full of Medicare brochures and a ticking clock most people don't fully understand. The good news: the rules are the same whether you live near Cal State Fullerton or up in the hills off Bastanchury. The trick is knowing which window to use, and in what order to make your decisions.

Here is a plain-language walkthrough of your Initial Enrollment Period (IEP) and the first steps to take, so you don't accidentally set yourself up for a lifelong penalty or a coverage gap.

Your 7-month Initial Enrollment Period, explained

Your IEP is built around your 65th birthday. It runs for 7 months total: the 3 months before your birthday month, the month you turn 65, and the 3 months after. This is the one-time window Medicare gives you to sign up for Part A (hospital) and Part B (doctor visits and outpatient care) without a late penalty.

When your coverage actually starts depends on when you enroll:

• Sign up in any of the 3 months before your birthday month → coverage begins the first day of your birthday month.
• Sign up during your birthday month or later → coverage begins the first day of the month after you enroll.

If you want your Medicare to be active the day you turn 65, don't wait. Enroll early in the window.

Step 1: Decide if you need to enroll at 65

Not everyone signs up right away. Ask yourself two questions:

Am I already getting Social Security? If yes, you're likely enrolled in Part A and Part B automatically. Watch your mail for your red, white and blue Medicare card.

Do I have job-based health insurance (yours or a spouse's)? If the employer has 20 or more employees, you may be able to delay Part B without penalty and use a Special Enrollment Period later. If the employer is smaller, Medicare usually becomes your primary coverage at 65 — and delaying can be costly. COBRA and retiree coverage do not count as active employer coverage for this purpose.

When in doubt, call your benefits department and ask, in writing, whether your plan is "creditable" for Medicare.

Step 2: Sign up for Part A and Part B

Most people sign up online at ssa.gov, since Social Security handles Medicare enrollment. You can also call Social Security at 1-800-772-1213 or visit a local office. Fullerton residents can use the Santa Ana Social Security office, which serves much of north Orange County.

Part A is premium-free for most people who worked and paid Medicare taxes for at least 10 years. Part B has a standard monthly premium set each year by CMS. If your income is above $109,000 as a single filer (or $218,000 for a couple) in 2026, you'll pay an IRMAA surcharge on top of the standard Part B and Part D premiums.

Step 3: Choose your coverage path

Once you have Part A and B, you have a decision to make. There are two main roads:

Original Medicare + a Part D drug plan + (optional) a Medigap policy. You keep the freedom to see any provider nationwide that accepts Medicare. Medigap helps cover out-of-pocket costs like deductibles and the 20% Part B coinsurance.

Medicare Advantage (Part C). These are all-in-one plans from private insurers that bundle Part A, Part B and usually Part D, often with extras like dental or vision. You use the plan's network. Fullerton is in Orange County, where a wide range of Medicare Advantage plans are offered — you can compare them on medicare.gov's Plan Finder using your ZIP code.

There is no universally "right" answer. It depends on your doctors, your prescriptions, your travel habits and your budget.

Step 4: Don't skip Part D — even if you take no drugs

This is the single most common mistake at 65. If you don't sign up for a Part D drug plan (or have other creditable drug coverage) when you're first eligible, you can be charged a Part D late-enrollment penalty for every month you went without — and it's added to your premium for as long as you have Medicare.

Some Part D basics to know for 2027:

• The Part D deductible can be up to $615 in 2026 and up to $700 in 2027.
• Your total out-of-pocket for covered drugs is capped at $2,100 in 2026 and $2,400 in 2027.
• The old "donut hole" coverage gap was eliminated in 2025 — Part D now has three phases instead of four.
• You can opt into the Medicare Prescription Payment Plan, which spreads your drug costs into level monthly payments instead of big one-time charges at the pharmacy.

Step 5: Mark the other enrollment windows

Your IEP is your first shot, but not your only one. Keep these dates on the fridge:

• Annual Enrollment Period: Oct. 15 – Dec. 7 each year. This is when anyone with Medicare can change Part D or Medicare Advantage plans for the following year. The window open now sets your 2027 coverage.
• Medicare Advantage Open Enrollment: Jan. 1 – March 31. If you're already in a Medicare Advantage plan, you get one chance to switch to another one or drop back to Original Medicare.
