Original Medicare lets your parent see any doctor or hospital in the U.S. that takes Medicare, but it has no yearly cap on costs unless they add a Medigap policy. Medicare Advantage plans can cost less each month and may add extras like dental or vision, but usually use a network and may require prior approval. The right choice depends on your parent's doctors, health, budget and travel.

Your mom's mailbox has been full since September: glossy flyers promising $0 premiums, dental coverage and a grocery card. The TV ads say she's missing out. Her cardiologist's office says it doesn't take some of those plans. She asks what she should do, and you realize you aren't sure what the difference is either. Here's the trade-off in plain words, the deadlines that matter, and where to get free, unbiased help before the December 7 deadline.
The basic difference
With Original Medicare, your parent can use any doctor or hospital that takes Medicare, anywhere in the U.S., and usually doesn't need a referral to see a specialist or prior approval for care. They usually pay 20% of the Medicare-approved amount after the yearly deductible, and there's no cap on what they can pay in a year unless they add a Medigap supplement policy or have other coverage. Drug coverage comes from a separate Part D plan.
A Medicare Advantage plan is a private plan that must cover everything Original Medicare covers, often with drug coverage built in. Plans usually require using doctors in their network, may need referrals and prior authorization, and have a yearly limit on out-of-pocket costs. Many add extras Original Medicare doesn't cover, like some dental, vision and hearing care, according to Medicare's side-by-side comparison.
Either way, your parent keeps paying the Part B premium, which is $202.90 a month in 2026 for most people, with a $283 yearly Part B deductible, per Medicare. Some Advantage plans charge no extra premium, and some help pay part of the Part B premium.
The questions that decide it for your parent
Skip the ads and answer these with your parent:
- Are their doctors and hospital in the plan's network? Call each doctor's office and ask about the exact plan name, not just the insurance company.
- Do they travel or spend part of the year somewhere else? Networks are usually local, while Original Medicare works anywhere in the U.S. Neither generally covers care outside the country, though some Medigap policies and some Advantage plans cover emergencies abroad.
- How much care do they use? A parent who sees several specialists may care most about network and prior approval rules. A healthy parent may care more about the monthly premium.
- Can they afford a Medigap premium? Original Medicare plus Medigap usually means a higher monthly bill but fewer surprises. Advantage plans trade a lower premium for copays up to the yearly limit.
- Do the extras matter? Dental and hearing coverage can be worth real money. Here's what hearing aids cost and what covers them.
- Are all their prescriptions covered? Check every drug and the pharmacy they use in the plan's list.
The Medigap catch most families miss
The best time to buy a Medigap policy is the Medigap Open Enrollment Period, the six months that start the first month your parent is 65 or older and enrolled in Part B. After that, Medicare warns, the options may be limited and the policy may cost more, depending on the state.
That matters if your parent is thinking about switching from Original Medicare to an Advantage plan. Medigap can't be used to pay costs under an Advantage plan, so many people drop it. Coming back later may mean a harder or more expensive time buying it again. There are some protections: a parent who joined an Advantage plan for the first time in the past 12 months may have the right to switch back and buy a policy, and some states add their own rules. Check Medicare's Medigap guide before making the change.
Your parent can read a plan's yearly notice or a glossy mailer to Tiina, or share a photo, and hear what it actually says in plain words. She compares the options with them and helps them list questions for the counselor, and they decide.
The deadlines that matter
According to Medicare's enrollment calendar:
- October 15 to December 7: Open Enrollment. Your parent can switch between Original Medicare and an Advantage plan, change Advantage plans, or join, drop or change a drug plan. Changes start January 1.
- January 1 to March 31: Medicare Advantage Open Enrollment, only for people already in an Advantage plan. They can switch to another Advantage plan, or drop it, return to Original Medicare and join a drug plan.
- Special Enrollment Periods: certain events, like moving, open other chances to change plans during the year.
How to compare plans, and where to get free help
Use the Medicare Plan Finder with your parent's actual prescriptions and pharmacy, and compare the estimated total yearly cost, not just the monthly premium. If you'll be calling Medicare on your parent's behalf, you'll need their permission on file; here's how to authorize someone to talk to Medicare.
For a second opinion that isn't selling anything, call your parent's State Health Insurance Assistance Program. SHIP counselors give free, one-on-one help comparing costs and reviewing coverage. Call early in the enrollment period rather than the week of the deadline.
Be careful with anyone who calls offering a better plan, and never give your parent's Medicare number to a caller you didn't contact yourself. These five tells of a Medicare scam call are worth sharing with your parent this month.
If money is tight
If your parent has limited income and savings, there may be help with premiums and drug costs that changes the math entirely. State Medicare Savings Programs can pay the Part B premium and sometimes more, and Extra Help lowers Part D drug costs. Here's who qualifies for a Medicare Savings Program and how to apply.
Once a plan is chosen, keep the cards, the plan's member services number and its yearly notice of changes together, and read each Explanation of Benefits when it arrives. Here's what an EOB actually means.
