How can I can get my dad's medical bills and medication at no charge? Is that possible someone with Medicare at 88?

First, YOU should not be paying anything for his medical needs. If his income is low enough, he should be on Medicaid and Medicare, and his medication and co pays would be covered. My father earned about $1850 a month from Social Security which was low enough for him to qualify for Medicaid and reduced costs for medications. His copayments were very low. You need to bring him to social services and see what he qualifies for based on his income.

Kelvis, my first question is the important one
"Does your cousin know what s/he's talking about?"

Many younger/inexperienced/not from the US folks think that Medical care for the elderly is free in the U.S. It's not

So, if your cousin has no experience having Medicare himself or dealing with an Elder who does, s/he may simply be making an assumption.

It would be really hard to explain what is involved with Medical insurance here. What you first need to do is determine what type of coverage your Dad has.

Traditional Medicare with a supplemental and a separate prescription plan. (Does he have dental and vision?)

Medicare advantage which covers parts A&B and prescriptions but is contracted out by Medicare. (May cover dental and vision)

You need to understand what staying in network means. Copays and deductables. Maybe Dad needs more coverage than he now has. Maybe he could qualify for Medicaid as his supplement.

Dad should be getting yearly benefit books from UH explaining what they cover. Once you can get all his cards together and that booklet (don't worry if u can't find it), call your Office of Aging and make an appt to sit down with someone who can look at what Dad has now and maybe find him better Insurance coverage.

Be aware though, when you have employers insurance, if you drop it you usually cannot pick it up again. With my DHs employer, we have 3 policies we can choose from. Medicare Advantage (PPO*), Traditional BC/BS (PPO*) and an HMO (must use their doctors)

*PPOs are where networks are involved. You stay within their network providers you save money, use a provider not in their network, you pay more out of pocket.

This all can be very complex. Talk to Office of Aging before you talk with anyone else. Those insurance brokers (I guess thats what they r called) work on commission so do not have the clients best interest.

Does your cousin know what he's talking about?

If dad has straight Medicare and no supplemental insurance, he pays for Parts B and D and there are copays. And there is a deductible to be satisfied each year.

If he has a supplement, he pays for that, but there may still be co-insurance charges.

If he has a Medicare Advantage plan, he may pay less for coverage, but the coverage may need to be only with in-network providers and institutions.

You should not be spending YOUR money on dad's medical care. That should come out of dad's funds.

Is dad on Medicare? Medicaid?
Why are YOU spending a fortune on HIS medications and Medical expenses?
Hate to break it to you but most things in life are not "free". Someone somewhere along the line pays for things.
Is dad a Veteran? If so the VA can cover most of his Medical Expenses and Medications.
And if he is a Veteran they may pay for a lot more, and he may qualify for a few benefits or a LOT.
Check with your local Veterans Assistance Commission.
Or contact the VA in your area.

Does your Dad have supplemental insurance?
Without it his costs will be SUBSTANTIAL in age.
