Father (64) had Aortic Anyeurism and open heart surgery and suffered strokes. I am concerned about his substantial nestegg.

Are you his POA, so that you have authority to act on his behalf?

What is Father's cognitive state now? Can he comprehend and participate in discussions about his finances?

If you are POA and he is competent, why don't you both go to a financial planner and discuss his best options at this point? Supporting himself and paying for what might be substantial medical costs the rest of his life would be the first goal, I assume.

Your dad is still in tne hospital, yes? And he seems to have suffered a stroke during or after the surgery? I have to tell you, cognitive loss after that particular surgery is fairly common. What does the team say are his chances for making a good recovery in rehab?

I think your job right now is to understand his deficits and understand what the options for rehab are. You want him in the best short term rehab place near you, hoprfully one that can do cognitive rehab as well as speec, ot and pt .having him in a place that also has assisted living and long term care available might also be a good idea,, depending upon what sort of recovery is in the cards.

Remember those funds are there for his care. You should certainly consult an eldercare attorney, especially if there is a spouse involved, because the spouse needs to be protected from impoverishment.

His cognitive state is mediocre I guess...logic mixed with delirium still.
I don't think I am POA, how do I do that? He would gladly agree to that I'm sure.
I dont know if he has a trust lawyer. what if he doesn't?
I think he will be able to participate in discussions soon...maybe like 1-2 weeks.
Yes he is still in SICU, slated for private room tomorrow hopefully.

Tlass, my husband had this surgery 10 years ago. He didn't have a stroke, but he wasn't all there for the first couple of days. Ask the nurses about how he's doing . Ask for a consult from neurology (to determine how much damage there is from the stroke and where it is) and get pt started as soon as possible.

Is your mom still around, or does dad have a spouse? In other words, is it possible there is someone else who is poa?

Tlass, first thing is to get your Dad the best care possible. GM is a 'benefits rich' company and will likely have a terrific package for your Dad. It is also likely that they have a benefits person that will help guide you through all processes. There is probalby short term disability for the first 6 months or so. Then long term disability if Dad is still unable to return to work. Dad may (or may not) have opted for long term disability when he did his benefits selection. It wouldn't hurt to ask this question when you call the benefits team. The disability income will help pay the day to day bills, though it may not meet his previous income.
His health care plan will pay for medical bills. With a hospital stay, he will quickly be at any 'out of pocket' maximums . After that, his health care plan may pay the full bill! Call his health care plan provider (number on the back of his health care card) and make sure you understand what is covered with respect to rehab services. As Babalou stated, get the BEST care possible. Your Dad is young and has the potential for many happy years, but he has one good shot at a significant recovery. While he is in the hospital, ask around for the BEST rehab ;place. (The staff in hospitals too often make arrangements for the easiest rehab! Do your homework) .
No action is needed for 401k, IRA, investments, etc. They are the least of your problems right now. And, GM may have an Employee advisory service available - many large firms do! They will help identify rehabs, etc as well as in home services he may need in the future.
Have faith, most of us look awful post surgery, it takes a while to shake it off!

Dad is better, coherent mostly each day, things are looking up, especially on the Neuro recovery side.....rehab for left side deficit will inevitably take a long time and degree of recovery there is still unknown. He has moved from the ICU to a room and eating....etc
It feels great to finally say...He is "out of the woods" so to speak!
I can now work with him directly for decisions regarding the next steps! phew what a huge relief and Blessing!

Arrange a group meeting with his Trust lawyer, CPA, and money manager. Take good notes.

I'm so sorry. I didn't answer your question, rather spouted off with un-asked for advice. You're in good hands with Jeanne and Yoga. Be well.

When he went into the hospital did he designate a Health Care Proxy? If not you have to go by your state next of kin laws.

Tlass, that is SUCH great news! Thanks for updating us!

Hugs to him and to you.
