About the E00–E07 Code Range
These conditions involve the thyroid gland, including iodine-related disorders, underactive or overactive thyroid, gland enlargement, and inflammation.
E00 describes a condition linked to iodine deficiency during pregnancy, divided into neurological, myxedematous, mixed, and unspecified types. E01 groups iodine-related disorders, including diffuse or multinodular goiter, meaning thyroid enlargement. E02 identifies subclinical iodine-deficiency hypothyroidism, an underactive thyroid condition.
E03 separates other hypothyroidism by congenital forms and forms linked to substances, infection, or thyroid atrophy. E04 distinguishes nontoxic goiter with diffuse enlargement, a single nodule, or multiple nodules. E05 divides thyrotoxicosis, or hyperthyroidism, by goiter or nodule pattern and other named forms. E06 separates thyroiditis, or thyroid inflammation, into acute, subacute, chronic, autoimmune, and drug-induced forms. E07 groups other thyroid disorders, including excess calcitonin secretion and dyshormogenetic goiter.
