Turning 65 in Tucson: Your Medicare Checklist

Turning 65 is one of the most important financial and healthcare milestones of your life. Done right, it sets you up for affordable, comprehensive coverage for decades to come. Done wrong, it can mean permanent penalties and coverage gaps. Here's exactly what to do — and when.

Start Here: 3 Months Before Your 65th Birthday

✅ Step 1: Check Your Social Security Status

If you're already receiving Social Security benefits when you turn 65, you'll be automatically enrolled in Medicare Parts A and B. You'll receive your red, white, and blue Medicare card in the mail about 3 months before your birthday. You do NOT need to take any action to enroll in Parts A and B.

If you're NOT yet receiving Social Security (you're still working or delaying benefits), you must actively enroll in Medicare. Do this at SSA.gov or your local Social Security office.

✅ Step 2: Decide Whether to Enroll Now or Delay

If you're still working at 65 and covered by a group health plan from an employer with 20+ employees, you may be able to delay Medicare enrollment without penalty. If your employer has fewer than 20 employees, Medicare becomes primary — enroll on time regardless.

COBRA does not count as creditable coverage for Medicare purposes. If you're planning to retire and go on COBRA, enroll in Medicare during your Initial Enrollment Period — don't use COBRA as a bridge and delay.

✅ Step 3: Gather Your Information

Before you start comparing plans, pull together:

• A list of all your current prescription medications (name, dosage, frequency)
• Your current doctors' names and NPI numbers (or their clinic names)
• Your current health insurance cards and policy information
• Your Social Security number
• Your Medicare card (when it arrives)

✅ Step 4: Understand Your Two Main Paths

As a Tucson resident, you have two main approaches after Original Medicare:

• Original Medicare + Medigap + Part D — predictable costs, any doctor nationwide, higher monthly premium
• Medicare Advantage (Part C) — often $0 premium, extra benefits, network-based care

✅ Step 5: If Choosing Medigap — Act During Your Open Enrollment Window

Your Medigap Open Enrollment Period is a 6-month window starting the first month you're both 65 AND enrolled in Part B. During this window, no insurer can deny you coverage or charge more based on your health history. After this window closes, you may face medical underwriting — and if you have pre-existing conditions, you could be denied or charged significantly more.

This window does not repeat. If you want Medigap, act during this period.

✅ Step 6: Compare Part D Drug Plans

Even if you're choosing Medicare Advantage (which usually includes drug coverage), if you're going the Medigap route you'll need a standalone Part D plan. Use the Medicare Plan Finder at Medicare.gov to enter your specific medications and see your estimated annual cost under each plan available in your Tucson zip code.

Don't skip Part D enrollment if you don't take drugs now — the late enrollment penalty (1% per month for every month you went without coverage) is permanent and adds up quickly.

✅ Step 7: Verify Your Doctors Are Covered

If choosing Medicare Advantage, call each of your doctors' offices and confirm they accept the specific plan you're considering. Online directories are frequently outdated — a phone call is the only reliable confirmation.

✅ Step 8: Enroll in Your Chosen Plan

You can enroll in Medicare Advantage or Part D plans online at Medicare.gov, by calling the plan directly, or through a licensed Medicare agent (free to you — agents are compensated by the insurance companies, not by you).

For Medigap, apply directly with the insurance company or through an agent. Your coverage typically starts the first day of the month after your application is accepted.

After Your Birthday: Don't Forget These

✅ Step 9: Cancel Your Previous Coverage

Once your Medicare coverage is active, cancel your previous health insurance to avoid paying duplicate premiums. If you were on an employer plan, coordinate the end date carefully so there's no gap.

✅ Step 10: Schedule Your Welcome to Medicare Visit

Medicare covers a one-time "Welcome to Medicare" preventive visit within the first 12 months of Part B enrollment. Schedule it — it's free and gives you a baseline health assessment with your new Medicare doctor.

✅ Step 11: Set Up Your MyMedicare Account

Create an account at MyMedicare.gov to track your claims, check your coverage, and manage your Medicare information online.

Common Turning-65 Mistakes to Avoid in Tucson

• ❌ Relying on COBRA and delaying Medicare — COBRA doesn't give you SEP rights
• ❌ Missing the Medigap open enrollment window — it doesn't come back
• ❌ Skipping Part D because you don't take drugs — the penalty is permanent
• ❌ Not verifying your Tucson doctors are in-network before enrolling in an HMO
• ❌ Choosing the lowest premium without checking drug costs — total cost matters, not just the premium
