Income for Medicaid in IN is no more than $2742 a month. He has $2848/mo. Ugh. $100 a month too much to qualify. anything we can do?

You will need to see an Elder Lawyer concerning a Miller trust. The money placed in it goes back to Medicaid upon the recipients death.

Your parent needs to establish a Miller Trust to assign the excess income to the state upon death.
