Iodine-deficiency related (endemic) goiter, unspecified

This code represents an enlargement of the thyroid gland (goiter) that is caused by insufficient dietary iodine, without further specification of its morphology or severity. It signifies a goiter that is endemic to a region where iodine deficiency is prevalent. The condition results from the thyroid's attempt to compensate for low iodine levels by growing larger to capture more available iodine.

Use this code when documentation clearly states an "iodine-deficiency related goiter" or "endemic goiter" without specifying if it is diffuse or nodular, or if it is associated with hypothyroidism or hyperthyroidism. This code is appropriate when the provider attributes the goiter directly to iodine deficiency and no other specific type of goiter is identified.

• Do not use this code if the goiter is specified as diffuse (E01.0) or multinodular (E01.1).
• Consider sequencing this code after any associated nutritional iodine deficiency (E00.-) if documented.
• Ensure documentation explicitly links the goiter to iodine deficiency; otherwise, a general goiter code (e.g., E04.-) might be more appropriate.
