Will my grandmother lose her Medicaid or Medicare if we sell her house?

WHICH ONE DOES MY GRANDMOTHER HAVE TO SIGN HER HOME OVER TO MEDICAID OR MEDICARE

Medicare she will have no matter what. Gran paid into Medicare by having some of her wages go into FICA (for future SS & Medicare) all her working years.

For Medicaid, the ? will be about if she sells the house, what she does with the assets (the proceeds) from the sale. If she just rents & keeps the $ as savings, then she will be ineligible for Medicaid as she has too much $. End-stage renal may have a different criteria for eligibility, so ask the atty if so.
But if it's a lateral sale…like she sells old house for 90K and buys a house with a better layout for her needs for 90K, there's no asset or income gain, so should not be an issue for Medicaid. The tricky part is getting all aspects of both sales done within a month, so that grannie starts the month low-income and ends the month low-income. Another option is for grannie to set the house sale $ into a special needs trust that is Medicaid compliant. None of this is simple - really a Medicaid compliant SNT is not ever a DIY project - and really grannie should meet with an elder law atty before doing any of this.

? for you?
is the house completely owned by grannie? or are you part owner and all the recorded legal at the courthouse shows you as part owner and since when?
&
Are you her caregiver? and have been her caregiver full-time for at least 2 years?
If so, carefully & clearly speak with the atty as to just how your state does the MERP - estate recovery exemptions and exclusions for family caregivers regarding you inheriting the house (if that is what grannie has as per her will).

Also try to get a realistic idea of what the house is worth. The 100K is that what the tax assessor has for value? if so, it may not be accurate as to what the house can realistically sell for especially is grannies house has delayed maintenance and there are tear-down/rebuilds in her neighborhood which affects all property values to go higher. Medicaid is pretty much a stickler for FMV on property. It could be worth getting house appraised to find out a more accurate value.

When it comes to selling assets, getting cash, etc. it may effect Medicaid eligibility. It's such a vital issue that IMO, I would consult with an Elder Law attorney in her jurisdiction to discuss the issue. Make sure the attorney knows the rules/law on Medicaid Asset protection. I would make certain that any move I made that would place her medical qualification in jeopardy was evaluated by an expert.

I read further about Medicaid QMB and understand your question a lot better now. I hope someone will come along who will know more about it.

Is it Medicaid QMB or Medicare QMB? She will keep her Medicare and whatever subsidies are allowed for her, such as QMB. Medicaid would be a different matter altogether.

A prime example:

I moved in with my mother when my father passed away and it became apparent that she couldn't live alone because she was falling and couldn't manage her finances. (Dad always did all of the finances - she had no clue even how to balance the checkbook.) Mom and Dad owned the house jointly, so when he passed away, it went into Mom's name.

Mom is now in a nursing home on Medicaid, and I still live in the house, pay the mortgage, taxes and utility bills myself. I'd love to sell it and move, but I can't - 1) because Mom needs me close by, and 2) because if I sold the house, it would immediately disqualify Mom from Medicaid for as long as it took to spend down the money from the sale of the house. That means that the nursing home bill of over $8,000 per month would be her responsibility - so with a house that is probably not worth more than $40,000 at the most, that money would run out quickly, and then we'd have to re-qualify her for Medicaid - and I'd have to find someplace else to live, on top of it.

Many caregivers are in this situation.

I am not located in TN, but here in Michigan, if you are on Medicaid and you divest (sell) any assets, like your home, you are instantly disqualified for Medicaid until that money is spent - then you have to go through the whole process of signing up again, and you have to prove that you no longer have the money from the sale of the asset.

So in short, at least here in Michigan, YES, she would lose Medicaid. It would gain you nothing to sell the house, because the money would have to be spent down before she would qualify for Medicaid again. This would leave her responsible for all of the expenses that Medicare doesn't cover.

Also - don't transfer the house to anyone else's name - that's the same as selling it in the eyes of Medicaid.
