If you made changes to your Medicare coverage during the Annual Enrollment Period (AEP) your new plan will go into effect January 1, so this is the time to get organized so your new benefits start smoothly.

Even if you didn’t make any changes, your current plan may have—and those updates also begin January 1. It’s important to review your documents carefully to avoid surprises at the pharmacy or doctor’s office.

Here are the key steps everyone should take now to be ready.

1. Watch for New ID Cards and Welcome Packets

If you enrolled in a new plan, your new insurance card and welcome packet should arrive before the end of December. These materials typically include:

Your ID card
A Summary of Benefits
Provider directories
Drug formulary (for prescription plans)

Tip: Make sure your mailing address is current with your plan so your card and documents don’t get lost.

2. Read Through Your Plan Details (Yes, Really!)

Even if you've had Medicare for years, it's worth taking time to review the details of your new or updated plan. Look closely at:

Which doctors, hospitals, and specialists are in-network
Your costs for office visits, urgent care, and hospital stays
How your copays, coinsurance, and deductibles work
Your pharmacy network and prescription drug coverage

Didn’t change plans? Still review your materials—existing plans can change their benefits, premiums, or drug coverage each year.

3. Double-Check Prescription Drug Coverage

Formularies (the list of covered drugs) can change annually. Make sure:

Your medications are still covered
The tier or cost hasn’t increased
Your pharmacy is still in-network

If something changed, talk to your doctor—there may be an alternative medication covered under your new plan or a way to file for an exception.

4. Confirm Your Providers Are In-Network

Before scheduling appointments in January, verify that your primary care doctor and any specialists accept your new plan. This is especially important if:

You enrolled in a new Medicare Advantage plan
Your insurer changed networks or provider contracts

5. Hold Onto Your Current ID Card Through December

Even though your new coverage starts January 1, keep your 2025 ID card on hand until the year ends. If you need care in December, providers will need your current insurance information.

6. Review Premium Payments and Billing

If your premium or plan changed, be sure you understand:

Whether your premium is deducted from Social Security or paid directly
When your first payment is due
How to set up automatic payments if you haven’t already

Missing your first payment could delay access to your benefits in January, so double-check early.

7. Keep Key Contact Info Handy

Have questions or run into issues? Be prepared by keeping these numbers easily accessible:

Your plan’s customer service number
1-800-MEDICARE (1-800-633-4227)
Your agent—we’re just a phone call away and happy to help you understand your plan.

Final Thoughts

Whether you made changes to your Medicare coverage or your existing plan simply updated its benefits, January 1 is an important date for your health care coverage. Preparing now ensures you don’t run into coverage issues, prescription problems, or billing surprises.
