Medicare, one question at a time.
These are the questions we answer at every Desert65 Medicare 101, in the order we teach them. Read straight through, or jump to the one that has been on your mind. Every answer comes with the same picture we put on the screen.

Who should I listen to?
Everybody turning 65 meets two kinds of people. Medicare Mary talks to a licensed agent before she decides anything. Neighbor Ned gets his advice from his brother-in-law, Facebook and Google — and he is very confident. Whenever Ned shows up in this story, something is about to go wrong.
Timing is the first place it shows. Procrastinating Pete turns 65 in September and files the Medicare envelope with the Costco coupons. Early Bird Ernie turns 65 in October and calls in July. October arrives and Ernie has nothing to scramble for.
When do I need to sign up?
Your first chance is a seven-month window: the three months before your 65th birthday month, your birthday month, and the three months after. Sign up early in that window and Medicare starts the month you turn 65.
What if I miss my window?
Missing it is not the end of the world, but it costs you. You may wait months for coverage to start, pay a Part B premium that is 10% higher for every 12 months you were late — for as long as you have Medicare — and pay a Part D penalty if you go 63 or more days without drug coverage.
- Know your dates. Your Initial Enrollment Period comes once.
- Don't delay. The longer you wait, the more it can cost.
- Talk with an agent about your options. Peace of mind today, lower costs tomorrow.
Am I enrolled automatically?
One question changes all the instructions: are you already receiving Social Security? Automatic Annie is. Her red, white and blue card shows up about three months before her birthday and she does nothing. Manual Marvin is the same age with the same birthday month, but he is not on Social Security yet — so nothing shows up, and he has to apply.
Marvin's homework is not hard. He can apply online at ssa.gov/medicare, by phone at 1-800-772-1213, or in person at his local Social Security office. The other difference: Annie's Part B premium comes out of her Social Security check; Marvin gets a bill from Medicare, usually every three months.
Still working at 65?
Working Wanda loves her job and has insurance through it. Her neighbor says "take Medicare at 65!" Her coworker says "wait until you retire!" Both sound confident. Neither looked at her plan. The right answer depends on the size of her employer, the coverage from her current job, what each option costs, her spouse's coverage and her prescriptions.
The employer's size is the hinge. With 20 or more employees, the work plan pays first and Part B can usually wait with no penalty later. With fewer than 20, Medicare pays first — and if you skip Part B, you can be responsible for 100% of your doctor's costs.
How does retiring work?
Retirement Randy worked until 68 and delayed Medicare — totally fine. Then he assumed Medicare knew he had retired. Not fine. You have to tell Medicare when you will lose your work coverage and want Part B to start. You get an eight-month special window after work coverage ends, but Medicare does not start the day you ask.
What if I'm on COBRA?
COBRA Carl retires at 65. HR says "you get COBRA for 18 months," and Carl figures he'll deal with Medicare later. Big mistake. COBRA is not coverage from current work, so it does not pause your Part B deadline.
What are Parts A, B, C and D?
Two teams. Parts A and B are run by the government and together they are "Original Medicare": A covers hospital stays, skilled nursing and hospice; B covers doctors, outpatient services, tests and equipment. Parts C and D come from private companies: C is Medicare Advantage, private plans that bundle A, B and usually D; D is prescription drug coverage.
Supplement or Advantage?
Think of it like two resort styles. All-Inclusive Al picks a Medicare Supplement: he pays a monthly premium and most of his Medicare-covered costs are already handled when he needs care. Pay-as-you-go Patty picks a $0-premium Medicare Advantage plan: low cost up front, then copays or coinsurance for visits, hospital stays and tests as she uses them. Neither one is better for everyone. One of them is better for you.
The Supplement is the all-inclusive stay: hospital, skilled nursing, hospice and any doctor that takes Medicare, anywhere in the country — but Part D, dental, vision, hearing, gym and over-the-counter items are not included. Medicare Advantage often has a $0 premium (you still pay Part B), uses a plan network, charges you for what you use up to a yearly limit, usually builds in drug coverage, and often adds the extras.
Will my doctor take it?
Doctor-Loyal Diane only cares about one thing: is Dr. Smith in the network? Great — then we only look at plans that include Dr. Smith. Before you pick any plan, check your primary doctor, every specialist you see, your hospital, and anywhere you travel or snowbird. The coolest commercial is useless without Dr. Smith.
Are my prescriptions covered?
Prescription Patty takes 15 medications. Her neighbor loves their plan, so Patty wants the same one. Great plan for the neighbor — terrible fit for Patty. Plans differ on which drugs are covered, what tier each drug sits in, and which pharmacies are preferred. Same zip code, same age, different medicine cabinet. Check first.
Is the $0 plan the best?
Zero-Dollar Zeke found the cheapest plan — $0 premium! He found the premium. He has not found the cost yet. Every plan has several costs: the premium, copays, the maximum out-of-pocket, prescriptions, and the doctor network. The premium is one part of the big picture.
When can I change plans?
Three windows. October 15 – December 7 is Annual Enrollment, when everyone can change plans for the new year. January 1 – March 31 is the Advantage Open Enrollment window: if you are on an Advantage plan, you get one switch. And any time you qualify for a Special Enrollment Period — you move, lose coverage, qualify for Extra Help, and more. Supplement plans can be changed at any time, but the new company may ask health questions.
Should I review it every year?
Set-It-and-Forget-It Fred picked a plan four years ago and hasn't looked since. "It worked fine last year." Since then his prescriptions changed, one doctor left the network, the plan changed its benefits, and a letter came every fall. Fred didn't change. Everything around Fred did.
Neighbor Ned's greatest hits
"Wanda, you don't need Part B." "Patty, all the drug plans are pretty much the same." "Zeke, $0 means free." "I picked my plan because Joe Namath was on TV." Ned is a nice guy. He's just not a Medicare expert.
How do I do this right?
Be a Medicare Mary. Borrow her five-step checklist.
- Know your dates. Build the timeline early.
- Check every doctor. Before you pick a plan.
- Answer the Social Security question. Automatic, or homework?
- Run every prescription. Same plan ≠ same fit.
- Review every year. Before surprises find you.
What does a review look like?
About 45 minutes, by phone or in person. No cost, no obligation — talking with us is always free. We are independent, so we compare plans from many companies. We start with you: your doctors, your drugs, your budget. And we check it again every year before it changes.
A word about AI
We use it, but differently than most companies. AI does the busy work behind the scenes — organizing, comparing, analyzing, researching — so nothing gets missed. That frees us up for the important things: talking to you, helping solve problems, and answering your calls. Technology behind the scenes. People in front of you.
Have a question that isn't here?
Bring it to a Medicare 101, or skip the room and just call. About 45 minutes, no cost, no obligation — and we start with you, not the insurance company.
