If you do not have much money, and you want to plan wisely for your senior years, the time to do it is when you're in your 60's and 70's. If you have a very small amount of assets, and you fear you may end up with a serious condition such as Alzheimer's that will deplete your assets and cause you to have to have long term care that would totally wipe you out financially, maybe you'll want to begin giving your assets to your children.
You'll have to risk it that anything that happens to you, if you gave away that money or property less than five years ago, after you've depleted everything you own now, and they start thinking of putting you on Medicaid, the Medicaid system would do a "look back" and would require that the relative value of whatever that asset was be used to pay for your care before they qualified you for Medicaid. And if this man's mother had done that in her 70's or even in her 80's, he'd have the assets now, and she'd have a small amount of stuff, and if she were to become very ill and stay that way for a long period of time (longer than Medicare would pay for her care) then she'd pass smoothly over to Medicaid.
But to suddenly jump up, when Mother is 90, and decide you want to do something that would cover her and so that a nursing home would not get all her money is just stupid. And no amount of contriving about something that might happen is going to be worth paying out big bucks to some estate planner at this age and stage in her life. Most people who are 90 are not looking at 5 more years of any kind with any great optimism. Most people this elderly are not anticipating a long debilitating stay in a long term care facility which will suck away all the estate's assets. Usually the "super old" tend to drop rather quickly when they do have a debilitating health crisis.
If I was a sixty or seventy year old who has had several health scares, or whose parents and relatives have tended to come down with early dementia, I might think long and hard about putting some assets in trust for my heirs as well as purchasing some long term health care insurance.
If I were a 90 year old, even one with great health and a family history of longevity, I think I'd probably chance it that I'm not going to need too much or too expensive a long term care jaunt and that my son will still inherit plenty, even if I have had to pay my own medical bills.
Nursing homes LOVE Medicaid, don't let them fool you. They are the greatest users of this government benefit. It's not the individuals who are sucking away this government money paid for by the taxpayers, it's the long term health care facilities. If we cancelled this one, it's amazing how many new ways we'd find to care for long term illness.
