When do I start the Medicaid process?

First find out if the NH accepts Medicaid. Some don't, and then you would also need to find a new facility.

You should start the Medicaid process ASAP as it takes time to get approval - usually it takes months. Hopefully, the social worker at the NH will be able to guide you on this. Also, it's a good idea to consult an attorney to help fully understand all the paperwork. You are only allowed $2000.00 in bank account and other restrictions, etc. Wishing you the best.
