Your county Area Agency on Aging services are free- they will have a Medicaid counsellor who can inform you as to the basic regulations, give you a "ballpark" idea of how the state will divide your assets, what will be set aside for your support (all states have rules against "spousal impoverishment") what the 5 year "look back" is, confirmation that you will not be made to leave your house, etc.
An Elder Law attorney, which does cost, will guide you to Medicaid planning that protects assets for you as much as the state allows. This is especially important if you have 401Ks, stocks, investments of any kind.
The Area Agencies on Aging do this all the time as any person entering a nursing home, even if private pay, will be expected,
at some point,to require Medicaid payment. They are tasked with verifying that the person entering the SNF did indeed require nursing home level of care at the time of admission.
The Area Agency people can also tell you what assistive livings and what nursing homes accept Medicaid. He will be more attractive for admission if you have at least 3 months private pay available. If they hint at 6, just go, "Hmm", they can't legally require it.
Picking facilities that accept Medicaid will cut down on the number of moves your husband needs to make as he declines.
I used to work at a county nursing home. Many days, 10:30-11 am brought the buses from nearby SNFs, which did not accept Medicaid, with the next poor soul (s) who had exhausted their savings- staying past 11 am would skip to a new billing day, so out the door with you!
