Code Description

ICD-10 E03.0 is a billable code used to indicate a diagnosis of congenital hypothyroidism with diffuse goiter.

Key Diagnostic Point:

Congenital hypothyroidism with diffuse goiter is a condition characterized by an underactive thyroid gland present at birth, often accompanied by an enlargement of the thyroid gland (goiter). This condition arises due to various genetic factors or iodine deficiency during pregnancy. The thyroid gland is crucial for producing hormones that regulate metabolism, growth, and development, particularly in infants and children. In congenital hypothyroidism, the lack of thyroid hormones can lead to severe developmental delays, intellectual disabilities, and growth retardation if not diagnosed and treated promptly. The presence of a diffuse goiter indicates that the thyroid gland is enlarged but not nodular, which can occur due to overstimulation by thyroid-stimulating hormone (TSH) in response to low hormone levels. Diagnosis typically involves thyroid function tests, including serum TSH and thyroxine (T4) levels, and may be confirmed through imaging studies. Early detection through newborn screening programs is critical to prevent long-term complications.
