Although at 65, if we can get him on Medicare, he will get some Medicare coverage
For now, while he can no longer get psychiatric care in inpatient mental health facilities, Medicaid apparently will cover mental healthcare in the psych ward of a regular hospital.
The trouble is that most hospitals don’t have psych wards.
I am lucky that my daughter had Obamacare when she had inpatient stays. There is also a nearby hospital with a psych ward that she went to. All were very short term stays though, less than 30 days. I think her insurance only paid for 30 days max each stay. She is doing well now at 39, and has a very part time job that enables her to buy insurance. But she hasn’t needed a hold for some time now as her meds have kept her stable since 2019.
I wish you luck sorting out the rules for your brother.
