Congenital iodine-deficiency syndrome, neurological type

This code represents the neurological form of congenital hypothyroidism resulting from severe iodine deficiency during fetal development. It is characterized by significant neurological impairments, including intellectual disability, spasticity, and gait abnormalities, often without severe growth retardation.

Use this code for patients diagnosed with cretinism primarily manifesting with neurological deficits due to congenital iodine deficiency. Documentation should clearly specify the neurological type of congenital iodine-deficiency syndrome, often referred to as endemic neurological cretinism.

• Differentiate from myxedematous cretinism (E00.1), which primarily involves growth failure and hypothyroidism.
• Ensure documentation explicitly links the neurological symptoms to congenital iodine deficiency.
• Consider sequencing with codes for specific neurological manifestations if they are treated or assessed independently.
