Iodine hypothyroidism

This code represents hypothyroidism caused by either an excess or deficiency of iodine. It signifies a state of underactive thyroid function directly attributable to iodine imbalance, leading to symptoms such as fatigue, weight gain, and cold intolerance.

Use this code when documentation clearly indicates hypothyroidism resulting from iodine exposure, such as from iodine-containing medications, contrast dyes, or dietary factors. This diagnosis is supported by laboratory findings consistent with hypothyroidism (e.g., elevated TSH, low T4) alongside a documented history of iodine excess or deficiency.

• Differentiate from other forms of hypothyroidism (e.g., autoimmune, congenital) by ensuring the etiology is explicitly linked to iodine.
• Ensure documentation specifies whether the iodine imbalance is due to deficiency or excess, as this may impact treatment.
• Consider sequencing with codes for the specific iodine-containing substance if applicable and documented.
