I break every part of Medicare into short pieces, from hospital cover and office visits to drug lists and the windows that open once a year.
Medicare breaks into a handful of moving parts, and each one settles a different worry. Pick the part that fits your question and read that alone.
Hospital stays live in one spot, office visits in another, prescriptions somewhere else again. The names blur together on paper, so below I describe each part by what it actually pays and where it quits.
Six subjects I get asked about the most as sixty five draws near.
Part A
Part A carries inpatient stays, a run of skilled nursing after a qualifying stay, hospice support and some care brought to your home. Most people pay no monthly premium for it thanks to the years of work behind them.
The deductible is what catches people out. It lands per benefit period instead of once a year, so a second stay months later can hand it to you all over again.
Part B
Office visits, outpatient procedures, lab work, preventive checks and durable equipment all run through Part B. You pay a monthly premium, a yearly deductible, and then a slice of the approved amount on most of what follows.
That slice has no ceiling of its own, which is why the next thing I point people toward is what picks up the remainder.
Part C
An Advantage plan hands you Part A and Part B through a private company, usually wraps the drug plan in, and often piles on dental, vision or hearing extras. Care travels through a network, and referrals or advance approval can come with it.
It caps what you spend out of pocket in a year on covered services, something Original Medicare alone will not do. I tell everyone to check the doctor list and the drug list before anything else.
Medigap
A supplement policy rides alongside Original Medicare and covers part of the copays, coinsurance and deductibles left on your plate. The lettered plans are standardized, so Plan G from one company matches Plan G from the next.
Timing matters here more than anywhere else. A single open window arrives when Part B begins, and once it shuts, health questions can shape both your price and whether you get in at all.
Part D
Drug cover comes either as a standalone plan sitting next to Original Medicare or built into an Advantage plan. Either way it keeps a formulary, a list of covered medicines sorted into tiers that decide what each refill costs you.
Formularies get reshuffled every plan year, so a medicine resting on a cheap tier today can climb. The habit I recommend is holding your prescription list up against the plan list each fall.
Timing
Your first window opens three months before the month you turn sixty five and closes three months after it. Miss that stretch without other qualifying cover and you drop to a general window, with a premium penalty that follows you.
Special windows open behind events like leaving a workplace plan or moving out of a plan service area. One more window each year lets you switch plans for the season ahead.
Part A picks up hospital stays and Part B picks up office visits and outpatient care. Anything the pair of them skip lands on you, which is worth knowing before it happens rather than after.
One route runs your care through a network and tends to bundle the drug plan in. The other pays part of the tab Original Medicare leaves. Line up your doctors and your prescriptions and the choice usually makes itself.
Three side subjects that shift the answer more often than people expect.
Working Past Sixty Five
Staying on a workplace plan can push Part B back without a penalty, though the rules hinge on how many people your employer has. I would rather sort that out with you before the birthday window closes.
Help With Costs
Savings programs and drug cost help exist for households under certain income limits, and they can shave down premiums, deductibles or what you hand over at the pharmacy counter.
Yearly Habit
Plans mail a notice of change ahead of each new plan year. Reading it against your prescriptions and your doctors takes a few minutes and heads off most nasty surprises.
