What 99478 covers

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
