Short of paying out more money to your present health insurer or getting a court order then frankly you can’t do a thing, however, there are alternatives. Health care providers typically employ financial counselors to help people find all the options available to cover the cost of their treatment. There are sliding fee rates, payment plans, and charity care programs all in place as a means to help as many people as possible, regardless of that person’s personal income.
My suggestion is for you to call a treatment center, and make an appointment to speak with a financial counselor. Explain your situation, and as far as getting treatment goes, I'm confident you will be able to make your financial issues, a non-issue. Hang in there and remember, whenever you think you’re going thru hell, the best thing to do is keep right on going. Good Luck To You...
