When you say ACA do you mean Affordable care that is the govt healthcare? I am on that an sometimes do not pay mine until the 5th, no problem. You can also put them on automatic pay. I would call them and speak to a supervisor. They have to insure you.

Here is the
Leukemia & Lymphoma Society
They give grants to help,
They even pay the monthly payment for insurance
So worth a try
Also a company named healthwell don't know phone number
Hope this helps

Let me clarify what I just said. The insurance company that you had does not have to insure you but Health Marketplace does. I have Medical Mutual thru AC and love it. Good luck.

If you are over 65 I would go on Medicare and get a supplemental Insurance to cover whatever Medicare doesn’t pay.

Hoping and praying for the best.
