Why This Usually Falls to the Kids
Turning 65 sets off one of the most confusing paperwork seasons of a person's life: government mailers, carrier marketing, TV ads, and phone calls — all at once, all claiming urgency. Many parents are managing this while still working, caring for a spouse, or simply not wanting to think about it. So the research quietly lands on an adult child.
The good news: you don't need to become a Medicare expert to be genuinely useful. Most of the value you can add comes from a handful of concrete steps, done a little early. This checklist walks through them in order.
About Three Months Before Her Birthday
The Initial Enrollment Period is a 7-month window: the three months before your parent's 65th-birthday month, the birthday month itself, and the three months after. Starting your homework at the front edge of that window means no deadline pressure later.
The single most important early question: is your parent (or their spouse) still working with employer coverage? The answer changes everything about timing — with qualifying employer coverage from a larger employer, delaying Part B can be perfectly fine; without it, delaying creates permanent penalties. Don't guess on this one. Confirm it with the employer's benefits office or ask a licensed agent to walk through it.
- Confirm the enrollment window dates and put them on your own calendar
- Find out whether employer coverage is in the picture (this decides the Part B timing)
- Make a list of her doctors — and which ones she refuses to give up
- Make a list of her prescriptions, dosages, and preferred pharmacy
- Gather documents: Social Security info, current insurance cards, and any retiree-benefits paperwork
The One Big Decision: Advantage or Supplement
Nearly everything else in Medicare is logistics; this is the real decision. Medicare Advantage plans bundle coverage through a private insurer — often with low or $0 premiums and extras like dental and vision, in exchange for provider networks. Medicare Supplement (Medigap) pairs with Original Medicare — higher monthly premium, but freedom to see any doctor who takes Medicare and very predictable costs.
Neither is universally better; the right answer depends on your parent's doctors, medications, budget, travel habits, and tolerance for networks. The doctor and prescription lists you made in step one are exactly what's needed to compare real plans in her ZIP code. Our Medicare 101 guide explains the structure, and the plan comparison tool shows the trade-offs side by side.
Watch the Mailbox — and the Phone
From about age 64½ on, your parent's mailbox becomes a marketing battleground, and unfortunately the scam calls arrive on the same schedule. Two rules cover most of it: anything claiming to be Medicare that asks for her Medicare number, money, or an immediate decision is almost certainly not Medicare; and no legitimate agent will show up at her door unannounced.
This is an area where adult children genuinely shine — be the person she calls before responding to anything. Our Medicare Scam Awareness Center has a printable one-page checklist that's worth putting on her fridge.
Enrollment Month: Getting It Done
Enrolling in Parts A and B happens through Social Security — at SSA.gov, by phone, or at a local office — and if she already receives Social Security benefits, enrollment may happen automatically. Choosing an Advantage, Supplement, or Part D plan happens after that, and it's where a licensed agent can compare every option available where she lives at no cost.
One boundary worth knowing: you can research, compare, sit in on every appointment, and ask all the questions — but the enrollment decision and signature are your parent's, unless you're her legally authorized representative. That's a feature, not an obstacle; it keeps her in charge of her own coverage.
After Enrollment: The Last Four Steps
Once the cards arrive, four small tasks lock everything in: verify her doctors and pharmacy accept the new plan, set up automatic premium payments so coverage never lapses, schedule her free 'Welcome to Medicare' preventive visit within the first 12 months of Part B, and put October 15 – December 7 on the family calendar — the annual window to review and switch plans as her needs change.
If you want the whole journey in one interactive place, our My Medicare Timeline planner tracks these steps with progress that saves on her device — and the caregiver guide covers the family side in more depth. And if you'd rather walk through it with a person: that's literally what we're here for, at no cost, with adult children welcome in every conversation.
