My parents are 86 and 91, one with kidney failure on dialysis and the other with dementia. They live together and we have just started getting some help in. They are doing okay, but spending lots of money on care. They have LTC insurance for 5 and 3 years, respectively. How do you know when the smartest time to use it is?
I wish you the best in this. It can be a very challenging process to get through but if your claim is approved for payment, it is very much worth it.
I would use it now were it me.
You might want to get the advice of a financial advisor if you have one. But I would use it now. Especially in terms of someone in 90s with kidney problems.
