Transitory neonatal hyperthyroidism
ICD-10 P72.1 is a billable code used to indicate a diagnosis of transitory neonatal hyperthyroidism.
Transitory neonatal hyperthyroidism is a temporary condition observed in newborns, typically resulting from maternal hyperthyroidism or the presence of maternal thyroid-stimulating antibodies. This condition is characterized by elevated levels of thyroid hormones in the neonate, which can lead to symptoms such as irritability, poor feeding, rapid heart rate, and increased metabolic rate. The hyperthyroid state usually resolves within a few weeks after birth as the maternal antibodies diminish. Diagnosis is often confirmed through clinical evaluation and laboratory tests measuring thyroid hormone levels. Management may include monitoring and, in some cases, the use of beta-blockers to control symptoms. It is crucial for healthcare providers to differentiate transitory neonatal hyperthyroidism from other forms of thyroid dysfunction, such as congenital hyperthyroidism, to ensure appropriate treatment and follow-up.
Detailed records of thyroid function tests, maternal health history, and clinical observations.
Neonates presenting with irritability and feeding difficulties in the NICU.
Close monitoring of symptoms and laboratory values to differentiate from other endocrine disorders.
Comprehensive pediatric assessments including growth and developmental milestones.
Follow-up visits for infants previously diagnosed with transitory hyperthyroidism.
Awareness of long-term developmental impacts and the need for ongoing monitoring.
Used to confirm diagnosis of hyperthyroidism in neonates.
Document the reason for testing and results.
Neonatologists should ensure tests are performed in a timely manner to monitor thyroid function.
Common symptoms include irritability, poor feeding, rapid heart rate, and increased metabolic activity. These symptoms typically resolve as maternal antibodies decrease.
