The cost of a weeklong stay in the NICU can vary by hospital. For example, Nationwide Children’s Hospital typically charges $6,500 to $8,300 per day for NICU care. Based on those numbers, you could pay as much as $58,100 for a seven-day NICU stay. If your child has to go to the neonatal unit, ask for itemized bills so you can see what you are being charged for.
