Medicare is a beast. Honestly, most people I talk to feel like they’re staring down a mountain of paperwork and confusing acronyms when they first ask, how do i start medicare. It isn’t just about signing a paper and getting a card. It’s a timing game. If you miss your window, the government actually tacks on penalties that last for the rest of your life. That’s not a scare tactic; it’s just how the Social Security Administration (SSA) operates.
You’ve probably seen the stacks of mail piling up on your kitchen table. Those glossy brochures from private insurance companies make it look easy, but they often gloss over the "how-to" part of the actual federal enrollment.
The Magic Window: When You Actually Start
Most people get their start during the Initial Enrollment Period (IEP). This is a seven-month window. It starts three months before the month you turn 65, includes your birth month, and ends three months after. If you’re already collecting Social Security benefits, you’re in luck—you’ll likely be enrolled automatically. The red, white, and blue card just shows up in your mailbox about three months before your birthday.
But what if you’re still working? That’s where things get sticky.
If you have "creditable" coverage through an employer with more than 20 employees, you might not need to start Part B right away. You can wait. However, "might" is a dangerous word here. You need to verify with your HR department that your insurance is considered primary or secondary to Medicare. If you mess this up and try to sign up later, you’ll face a 10% penalty for every 12-month period you were eligible but didn't enroll. That adds up fast.

Breaking Down the Parts (The Alphabet Soup)
Medicare is split into different sections. Part A covers the big stuff—hospitals, skilled nursing, and some home health. Most people don't pay a premium for this because they’ve paid into the system through payroll taxes for at least 10 years.
Part B is your outpatient coverage. Think doctors’ visits, lab work, and medical equipment. This has a monthly premium ($185.00 in 2026, though this can be higher depending on your income). Then there's Part D, which is strictly for prescription drugs. You buy this from private companies, but the government regulates it.
What About Part C?
You’ve definitely heard of Medicare Advantage. This is Part C. It’s basically an "all-in-one" alternative to Original Medicare. It usually bundles A, B, and D together. While it sounds simpler, it often comes with restricted networks. You might find that your favorite specialist isn't "in-network," which can be a massive headache if you’re managing a chronic condition.

The Actual Steps to Enrollment
Stop waiting for a phone call. The government won't call you to sign you up. To how do i start medicare, you generally go through the Social Security website (ssa.gov). It’s the fastest way.
- Create a "my Social Security" account online. Do this early.
- Fill out the application for Medicare benefits. It usually takes about 10 to 20 minutes if you have your info ready.
- If you're still working and only want Part A (because it's free), you can specify that.
- Keep your confirmation number.
If you aren't tech-savvy, you can call 1-800-772-1213. Be prepared to wait on hold. A long time. Early morning is usually better. You can also visit a local Social Security office in person, though many still require appointments since the 2020 shifts in how they handle foot traffic.
Don't Forget the Supplement (Medigap)
Original Medicare only covers about 80% of your outpatient costs. That other 20%? That's on you. There is no "out-of-pocket maximum" in Original Medicare. If you have a $100,000 surgery, that 20% could ruin you.

This is why people buy Medigap (Medicare Supplement) policies. These are private plans that "fill the gaps" left by Part A and Part B. Plan G is currently the most popular because it covers almost everything once you pay your Part B deductible. It’s predictable. You pay your premium, and you don't worry about hospital bills.
Common Blunders to Avoid
IRMAA is a term you should know. It stands for Income-Related Monthly Adjustment Amount. If you’re a high-earner, the government is going to charge you more for Part B and Part D. They look at your tax returns from two years ago. So, if you retired recently and your income dropped, you can actually appeal this by filing Form SSA-44.
Another huge mistake is assuming Medicare covers everything. It doesn't.
- Long-term care (nursing homes) is not covered.
- Routine dental care is usually out.
- Vision and hearing aids aren't included in Original Medicare.
- Most care outside the U.S. is not covered.
If these things are deal-breakers, that’s when you look into those Medicare Advantage plans or specific private riders.
Actionable Next Steps
Start by checking your Social Security statement to ensure your work credits are accurate. If you don't have 40 credits, you might have to pay for Part A, which gets expensive.
Next, mark your calendar exactly three months before your 65th birthday. This is your "Go" time. Even if you plan to keep working, you should talk to your benefits administrator to see how your current plan coordinates with Medicare. Get it in writing. Verbal promises from HR won't stop the SSA from charging you a late penalty five years from now.
Finally, compare Medigap versus Medicare Advantage based on your specific health needs. If you travel a lot within the U.S., Medigap is usually better because it works with any doctor that accepts Medicare nationwide. If you're on a tight monthly budget and don't mind staying within a local network, Advantage might be the play.
Check the "Medicare & You" handbook that the government publishes every year. It’s dry, but it’s the gold standard for facts. Once you have your Part B start date, you have 63 days to get a Part D drug plan or you'll face another penalty there. Stay on top of the dates and the process becomes a lot less intimidating.
