Problem: An example would be if a newborn was to leave the hospital after birth and the mother takes the baby back to the pediatrician for being lethargic and not eating a few days later. The pediatrician discovers the baby to have bradycardia and hypoxemia and sends the infant to the hospital where he follows and treats the baby at the hospital in the ICU. The physician coding would be for the critical care received at the hospital and not for the office.
