Medicare 101 for Adult Children Helping a Parent (2026)

If you've just started helping a parent with Medicare, it can feel like a wall of letters, parts, and deadlines. Here's the whole picture in plain English, what the pieces are, what you actually need to do as the person helping, and where you can save your parent real money.

The four parts, in one minute

Part A covers hospital stays (most people pay no premium). Part B covers doctors and outpatient care, the standard premium is $202.90/month in 2026. Together, A and B are 'Original Medicare.' Part C, or Medicare Advantage, is an all-in-one alternative sold by private insurers that bundles A, B, and usually drug coverage. Part D is prescription drug coverage. Your parent has either Original Medicare (often plus a Part D plan and a Medigap supplement) or a Medicare Advantage plan, not both.

What you actually need to do as the helper

You don't need to become a Medicare expert. Your real jobs are four things: make sure your parent isn't missing money-saving programs they qualify for, keep an eye on deadlines, help them understand letters and bills, and step in if a claim is denied. The rest is mostly knowing where to look.

Getting permission to help

Medicare won't discuss your parent's account with you unless they've authorized it. To talk to 1-800-MEDICARE and see their claims, your parent signs Form CMS-10106 (Authorization to Disclose Personal Health Information). To handle an appeal, you'll also need Form CMS-1696 (Appointment of Representative). These are separate forms for separate jobs, set them up early so you're not stuck when something urgent comes up.

The deadlines that matter

The big one is the Annual Enrollment Period, October 15 to December 7 each year, when your parent can change or switch Medicare Advantage and Part D plans for the following year. There's also a one-time Initial Enrollment Period around their 65th birthday. Missing enrollment windows can mean lifelong penalties, so put these on your calendar.

Where the money-saving programs fit

This is where an adult child often finds real money. If your parent has limited income and savings, Extra Help cuts prescription costs to near zero (worth about $5,700 a year), and the Medicare Savings Programs pay the $202.90/month Part B premium, with QMB also covering deductibles and copays. Many people who qualify never apply because they assume they earn too much; 14 states plus D.C. don't count savings at all. It takes about two minutes to check.

A simple first-week checklist

1) Find out whether your parent has Original Medicare or Medicare Advantage, and the plan name. 2) Set up the authorization forms so you can help. 3) Run a free benefits check to see what they may qualify for. 4) Note the October 15 to December 7 enrollment window. 5) Save the number on the back of their Medicare card for questions.
