Health insurance isn’t covering NICU???

I just opened up our NICU bill and want to throw up. I have amazing health insurance (I’m a teacher and our union has fought for amazing health insurance). Our daughter was admitted to NICU for jaundice after being discharged after birth. I get the bill today...$13,100. It says “self pay ins” under insurance coverage (see pic below). Does self pay ins mean they processed it wrong and didn’t put me in as having insurance? Or is self pay ins mean I pay for my own health insurance? I’m so confused! Obviously I’ll call tomorrow am, but right now I’m freaking!!!
