When you leave/are fired from target COBRA is offered and it is expensive. Depending on your earnings you may be able to purchase your own insurance through ACA programs. In my case, my pay was too low to buy the ADA insurance so I have now qualified for Medicaid.
If you are not sure about what medical insurance you can get or qualify for, call a local insurance carrier and ask them to help you out or ask them if they can refer you to a broker who covers unemployed individuals. I needed help so I ended up calling a local insurance carrier and they referred me to a broker who does unemployment insurance. My experience with the broker was great....he gave me advice then answered questions and did not charge me anything for his help.
If you get insurance through the unemployment/government be very careful about applying and making sure that you get a vendor that covers your doctors. My problem came when they assigned me to a vendor that I did not ask for and I ended up having to make numerous calls to fix the problem.
In the end, I was covered, almost immediately by Medicaid and then ended up with my vendor of choice.....after a number of calls.
