Go to the hospital, the one run by your county if nothing else since as a government institution they cant turn down Medicaid.
Thatll handle the polyps and such. While hes there, push for him to be admitted, theyll have to bust out the specialist eventually if they do.
If he needs to go on Dialysis, some hospitals have dialysis outpatient clinics and are more or less obligated to take Medicaid.
Once you handle that or while you are handling that get into contact with one of those disability lawyers about getting him medicare for his dialysis.
Pun, if you need anymore help my parents both work in and around hospitals as medics and know tons of people with power in ERs and hospitals, so i can ask them for more solid advice but thats the basics of what they told me.
