Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 99477 covers

A neonatologist, pediatrician, or other qualified physician reports 99477 for the initial hospital day when a neonate 28 days old or younger needs intensive observation, frequent interventions, and other intensive care services, without meeting the circumstances for neonatal critical care. The infant may be cared for in a neonatal intensive care unit or another hospital setting providing this level of care. The service reflects active physician management, not routine newborn examination or ordinary nursery care.

Report the code once for the initial day of qualifying neonatal intensive care. Documentation should establish the infant’s age, clinical condition, need for close observation and interventions, and the physician’s evaluation and management that day. For a subsequent day of intensive care, select the applicable subsequent-care code based on the infant’s circumstances and birth-weight category. When the neonate is critically ill and receives neonatal critical care, use the neonatal critical-care code family instead.
