Hypernatremia of newborn
ICD-10 P74.21 is a billable code used to indicate a diagnosis of hypernatremia of newborn.
Hypernatremia in newborns is characterized by an elevated sodium concentration in the blood, typically defined as a serum sodium level greater than 145 mEq/L. This condition can arise from various factors, including inadequate fluid intake, excessive fluid loss, or a combination of both. In neonates, hypernatremia is often associated with dehydration, which can occur due to insufficient breastfeeding, formula feeding errors, or excessive insensible water loss. The clinical presentation may include signs of dehydration such as dry mucous membranes, decreased urine output, lethargy, and irritability. Prompt recognition and management are crucial to prevent complications such as neurological damage or renal impairment. Treatment typically involves careful rehydration, often with isotonic fluids, and monitoring of serum sodium levels to avoid rapid shifts that can lead to cerebral edema. Understanding the underlying causes and appropriate management strategies is essential for healthcare providers in neonatal settings.
Detailed records of fluid intake, output, and sodium levels are essential. Documentation should also include the clinical assessment of dehydration and treatment protocols.
Common scenarios include a newborn presenting with dehydration due to inadequate breastfeeding or a premature infant with insensible water loss.
Special considerations include monitoring for rapid changes in sodium levels and the potential for neurological complications.
Pediatric documentation should include a comprehensive history of feeding practices and any underlying medical conditions that may contribute to electrolyte imbalances.
Pediatric scenarios may involve older infants with hypernatremia due to gastrointestinal losses or inadequate fluid intake during illness.
Considerations include the need for interdisciplinary communication regarding fluid management and monitoring.
Used when managing a newborn with hypernatremia requiring intensive monitoring and treatment.
Documentation must include the clinical assessment, treatment plan, and ongoing monitoring of sodium levels.
Neonatologists should ensure that all critical care services are well-documented to support billing.
Common causes include inadequate fluid intake, excessive fluid loss due to vomiting or diarrhea, and conditions such as diabetes insipidus. It's essential to assess feeding practices and monitor fluid balance closely.
