2025 ICD-10-CM code P92.3

Underfeeding of a newborn infant.

Accurate coding requires careful evaluation of the newborn's feeding history, weight gain, and any underlying medical conditions.The most specific code reflecting the clinical situation should be selected.

Medical necessity is established by evidence of inadequate growth and development in the newborn. This is demonstrated by poor weight gain, failure to thrive, and symptoms consistent with underfeeding.The need for intervention is supported by clinical observations and appropriate investigations.

The clinical responsibility for diagnosing and managing underfeeding in newborns typically falls upon neonatologists, pediatricians, or family physicians.Depending on the underlying cause, other specialists (e.g., gastroenterologists, endocrinologists) may be involved.

IMPORTANT:Related codes within the P92 category may include P92.0 (Vomiting in newborn), P92.1 (Regurgitation and rumination in newborn), P92.2 (Slow feeding of newborn), P92.4 (Overfeeding of newborn), P92.5 (Neonatal difficulty in feeding at breast), P92.8 (Other feeding problems of newborn), and P92.9 (Feeding problem of newborn, unspecified).Consider using a more specific code if available.

In simple words: This code means the baby isn't getting enough to eat in the first month of life. This could be because of problems breastfeeding, not getting enough formula, or a medical condition affecting their feeding or digestion.

This code, P92.3, signifies underfeeding in a newborn, indicating insufficient caloric intake to meet the infant's nutritional needs during the first 28 days of life.It encompasses situations where the infant is receiving less nutrition than required for optimal growth and development. This can stem from various factors, including inadequate breastfeeding, insufficient formula feeding, or underlying medical conditions impacting the infant's ability to feed or absorb nutrients effectively.

Example 1: A newborn infant exhibits poor weight gain despite adequate breastfeeding attempts.The mother's milk supply is assessed, and supplementation is considered due to insufficient caloric intake., A premature infant struggles with suckling and swallowing, resulting in inadequate nutrient absorption.Specialized feeding techniques and monitoring are implemented to ensure sufficient caloric intake., A newborn with cleft palate experiences difficulties with feeding, impacting nutrient intake.Surgical correction and adaptive feeding strategies are used to manage the underfeeding.

Detailed documentation should include maternal and infant history, birth weight, weight gain patterns, feeding methods (breastfeeding, formula feeding, type of formula, feeding volumes), assessment of suck and swallow, presence of any gastrointestinal issues (vomiting, diarrhea), physical examination findings, and any laboratory investigations (e.g., blood glucose, electrolytes).

** This code is for use only on newborn records (first 28 days of life).It should not be used for maternal records.The code should be used in conjunction with other relevant codes if necessary to capture the full clinical picture.Always refer to the most up-to-date coding guidelines.
