Congenital iodine-deficiency syndrome, mixed type

This code represents a congenital condition resulting from insufficient iodine during fetal development, leading to a combination of neurological and hypothyroid symptoms. It encompasses cases where both mental and physical developmental delays are present due to iodine deficiency.

Use this code when documentation explicitly states a diagnosis of congenital iodine-deficiency syndrome with features of both neurological and myxedematous cretinism. This diagnosis is typically made in infants or young children exhibiting a spectrum of developmental impairments linked to maternal iodine deficiency.

• Ensure documentation specifies "mixed type" or describes both neurological and hypothyroid manifestations.
• Distinguish from other forms of congenital hypothyroidism not related to iodine deficiency.
• Code additional specific manifestations or complications separately, if documented.
