Turning 65 in California? Your Complete Medicare Checklist

Turning 65 is a milestone worth celebrating — and, if we're honest, a milestone that comes with a stack of paperwork and deadlines nobody warned you about. I've walked hundreds of Inland Empire families through this exact moment, from Chino Hills to Redlands, and I've found that having a simple checklist takes 90% of the stress out of it. Here's what to do, in order.

Step 1: Mark Your Initial Enrollment Period on the Calendar

Your Initial Enrollment Period (IEP) is a seven-month window: three months before your birthday month, your birthday month itself, and three months after. If your birthday is in November, your window runs August 1 through February 28. The key thing to know: enroll in the three months before your birthday month, and coverage starts right on time, the first day of your birthday month. Wait until your birthday month or later, and your start date gets pushed back. My advice: start the process two to three months before your birthday, not after.

Step 2: Decide If You Need to Sign Up at All

If you're already collecting Social Security, you're likely enrolled automatically in Part A and Part B, and your Medicare card will show up in the mail a few months before you turn 65. If you're not yet collecting Social Security, you'll need to actively sign up through the Social Security Administration. And if you're still working at 65 with health coverage through an employer with 20 or more employees, you may be able to delay Part B without penalty — but confirm this in writing before you assume it applies to you. Getting this step wrong is the single most common (and costly) mistake I see.

Step 3: Decide Between Original Medicare + Medigap, or Medicare Advantage

This is the fork in the road. Original Medicare paired with a Medigap policy gives you nationwide flexibility and predictable costs but a higher monthly premium. Medicare Advantage typically has a lower or $0 premium, often includes drug coverage and extras, but usually keeps you within a local network. Neither one is universally "better" — it depends on your health, your budget, your doctors, and whether you split time outside California. This is exactly the kind of decision worth talking through with a broker rather than guessing from a mailer.

Step 4: Lock In Your Medigap Rights Early, If You Want One

If Medigap is the right fit for you, timing matters enormously. You get a one-time, six-month Medigap Open Enrollment Period that starts the month you're 65 and enrolled in Part B. During this window, insurance companies can't deny you coverage or charge you more because of a pre-existing health condition. Miss this window, and in most states you could face medical underwriting later. California residents do get an extra safety net later on — our state's birthday rule lets you switch Medigap plans annually without health questions — but that first window at 65 is still your best and easiest entry point.

Step 5: Choose a Part D Drug Plan (Even If You Don't Take Medications Now)

If you go the Original Medicare + Medigap route, you'll need a standalone Part D prescription drug plan. Even if you're not on medications today, skipping Part D can cost you later: go 63 days or more without creditable drug coverage after your IEP ends, and you'll face a late enrollment penalty for as long as you have Part D. It's a small cost now to avoid a permanent one later.

Step 6: Review Everything Every Fall

Once you're set up, your job isn't done. Every year from October 15 to December 7, the Annual Enrollment Period gives you a chance to reassess your plan, your drug list, and your budget. Networks and formularies shift constantly, and the Inland Empire has seen real changes in which carriers offer the strongest local coverage year to year. A quick annual review can save you real money.
