Insurance Denied Coverage for Seizure Please fill gap

I have a gap in medical coverage for an epileptic grand mal seizure which nearly took my life last spring. I am fine now. Despite wonderful care and loving friends and family, the ambulance, ER, and admission to the ICU bill have not been able to be reconciled. I grow weary of the fight and would rather pay the bill. I was admitted to the hospital for four days on that night but face a large bill at the emergency room as if I were an outpatient. The insurance company thinks I left the emergency room and returned but they are part of the same facility and I was unconscious. Since the spring, I have fought to get coverage to no avail. Any amount would be greatly appreciated.

thank you so much
