Neonatal care

About 99478: Subsequent intensive care, very low weight infant

Reports a subsequent day of intensive inpatient evaluation and management for a critically ill infant aged 29 days or older weighing under 1,500 grams.

Code 99478 describes a subsequent day of intensive evaluation and management for a critically ill infant or young child aged 29 days or older whose current body weight is under 1,500 grams. It is typically reported by a neonatologist or pediatrician providing ongoing care in a neonatal or pediatric intensive care setting, where the infant needs intensive observation, frequent interventions, and other intensive services.

Select the code using the patient’s current body weight for the date of service, not birth weight; document that weight and the clinical work supporting intensive care. Report one daily service when the patient meets this code’s weight and care criteria. The 1,500-gram threshold distinguishes this service from the adjacent weight-based subsequent-care codes. The CMS facts provided list no additional payment rules for this code.
