Neonatal goiter, not elsewhere classified

This code describes an enlargement of the thyroid gland in a newborn, not specifically attributed to iodine deficiency, congenital hypothyroidism, or maternal thyroid dysfunction. It indicates an idiopathic or unspecified cause of neonatal goiter.

Assign this code when documentation confirms a goiter in a neonate without a specified underlying etiology, such as iodine deficiency or a known congenital anomaly. Supporting documentation should include physical exam findings of an enlarged thyroid and exclusion of other specific causes.

• Do not use this code if the goiter is due to iodine deficiency (E00.-) or congenital hypothyroidism (E03.0).
• Consider sequencing this code after a code for the underlying cause if one is identified later and is not specifically excluded by this code's "not elsewhere classified" nature.
• Ensure the documentation clearly states the patient is a neonate (birth to 28 days of age).
