...is Dad's SS and Retirement income per month somehow free from consideration in Medicaid paying for a Nursing Home? (Granted it is likely a silly question, but I am exhausted from trying to get it all squared away and, therefore, confused by all of it)
If Dad's assets are over the asset limit (often $2000) he can get under that limit by "spending down" his assets. For example, he can use some of it for a pre-paid burial plan. He can spend the excess assets on just about anything AS LONG AS IT IS FOR HIMSELF. No giving it to relatives or charities, etc.
If Dad's income is over the limit but still not enough to pay for his care (a common situation) there are ways to handle this that vary by state.
As far as I'm concerned, there are no silly Medicaid questions. That is a complicated subject, and all questions are reasonable!
I suggest you contact your Area Agency on Aging. (Here it is called senior-helpline. A google search will help you find it in your state.) Ask if they have resources to explain Medicaid requirements to you. You may ultimately want to contact an Elder Law attorney, but start with the Aging Agency.
BTW, if your Dad is married, the Medicaid requirements are quite different.
