4.5 Million Dollar Debit

Is there a such thing as an attorney to go against medical bills? I have a baby in the nicu that was born at 25 weeks in an emergency c section. Me and baby were almost dying. I had her at a hospital not covered by my insurance and it was not my choice to have her there. I went in to an appointment at a clinic within a hospital but the clinic is not associated with the hospital. Turns out my baby was not getting oxygen and my blood pressure even in high dose medication was through the roof. I was hospitalized without a choice as our lives were at risk. They called the hospitals that my insurance cover to try a transe ter but they did not have the level of nicu needed. The level my baby needed was at the hospital I was already at. Long story short hospital keeps calling asking how I want to pay, may daughter is still in the nicu and the bill is already at 4.5 million. We don’t qualify for Medicaid because apparently a couple making $40k combined a year is “too much” and if I apply for a hospital discount I’m responsible for 1.3 million. I can not afford it and I’m already tired and stressed as it is having to be at the hospital all day. I have been diagnosed with ptsd because the whole ordeal is a lot more complex than what I mentioned and I really don’t know what to do
