When to enroll, what the four parts of Medicare actually do, and how to make a sensible plan choice without losing a Saturday to comparison websites.
If you're turning 65 in the next twelve months, three things are about to start happening at once: a flood of mail from carriers you've never heard of, well-meaning advice from friends who picked their plan in five minutes and don't remember why, and a quietly ticking clock with real penalties attached. This is the plain-English version of what to do, in what order, with the bits that matter most highlighted.
I've been writing Medicare on the Connecticut shoreline for twenty-five years. Most of what people get wrong about Medicare is wrong because it was explained to them in a hurry, by someone with a script, on a thirty-second phone call. Slow down for ten minutes and the whole thing makes sense.
Medicare is one program with four lettered parts. Two are run by the federal government (A and B); two are run by private insurers under federal rules (C and D). The names sound like they're in random order, and that's because they were added to the program at different times by different acts of Congress.
You'll also hear about Medicare Supplement (Medigap) plans — private policies that fill the holes in Original Medicare (the 20% Doctor-coverage coinsurance, the Hospital deductible, etc.). Medigap is not a separate part of Medicare; it pairs with Hospital and Doctor coverage (Parts A and B) as an alternative to going the Advantage route.
The single most important thing to know is the seven-month Initial Enrollment Period (IEP). It runs from three months before the month you turn 65 through three months after.
If you're already collecting Social Security or Railroad Retirement benefits, the federal government will sign you up for Hospital and Doctor coverage (Parts A and B) automatically and mail you a card. If you're not, you have to actively enroll — either online at SSA.gov, by phone, or in person at a Social Security office.
You're 64 and 9 months, still working, and your spouse is on your employer health plan. The right answer is not always to enroll in Doctor coverage (Part B) at 65. If your employer has 20+ employees and you have credible coverage, you can usually defer Doctor coverage (Part B) without penalty until you stop working. Worth a 30-minute conversation — getting this wrong is a very expensive mistake.
Two questions decide it: how big is your employer, and how good is your current plan?
Once you have Hospital and Doctor coverage (Parts A and B), the next decision is whether to pair them with a Medicare Supplement (Medigap) plus a standalone Prescription drug plan (Part D), or to roll the whole thing into a Medicare Advantage plan that bundles Hospital, Doctor, and Prescription drug coverage, plus extras, under one private carrier.
The honest tradeoffs:
Neither is universally better. The right answer depends on the specifics of your health, your network, your prescriptions, and your tolerance for variability. There's a longer comparison here.
Most Medicare conversations end with: "— so which one should I pick?" The 30-minute call answers that, once we've looked at your doctors and your medications.

The late-enrollment penalty is roughly 1% of the national base beneficiary premium for every month you delay, added permanently to whatever prescription drug plan you eventually pick. The dollar amount is small — a few dollars a month, lifetime — but it grows for every month you wait, and the math gets ugly the longer you put it off.
The exception: if you have credible prescription drug coverage from another source (an active employer plan, the VA, certain union retiree plans), you don't accrue the penalty during that period. Get the credible-coverage letter in writing and keep it.
If you're 65 (or about to be) and already on HUSKY (Connecticut's Medicaid), the Medicare conversation is the most consequential one you'll have. There are specific Medicare plan types — Dual-Eligible Special Needs Plans (D-SNPs) — designed for people on both programs, which, for those who qualify, can include $0 copays, broader benefits, and care management built in. The plan choice matters more here than almost anywhere else in Medicare. Read about how the two programs work together.
I'm an agent — multi-carrier, certified annually with each. I don't charge you for the consultation. The carriers pay a small commission if and when you enroll through me, the same commission whether you enroll through me or through a 1-800 number. So my job is genuinely to figure out what fits your life, not to push a particular plan.
If you're three to nine months out from your 65th birthday, the right time to start the conversation is now — before the mailings, before the deadlines, while there's still room to think.
If anything in this piece applies to your situation, the fastest way to figure out what to do is one short conversation. Free, 30 minutes, no pressure and no follow-up calls you didn't ask for.
