About the E00–E07 Code Range
ICD-10 codes E00-E07 cover a broad range of disorders affecting the thyroid gland, including iodine deficiency syndromes, hypothyroidism, goiters, thyrotoxicosis, thyroiditis, and other specified thyroid conditions. These codes are used to detail specific thyroid diseases for accurate diagnosis and treatment documentation.
The range begins with congenital iodine-deficiency syndromes (E00-E00.9), which include neurological, myxedematous, and mixed forms often referred to as endemic cretinism. Codes E01 to E02 focus on iodine-deficiency related goiters and hypothyroidism. Other hypothyroidism types, such as congenital and drug-induced hypothyroidism, fall under E03, with detailed subtypes like myxedema coma (E03.5). The E04 series addresses nontoxic goiters including diffuse or multinodular goiter, sometimes called simple goiter. The thyrotoxicosis or hyperthyroidism category (E05) includes Graves' disease and toxic nodular goiters, with distinction between presence or absence of thyrotoxic crisis (storm). Thyroiditis codes (E06) cover acute, subacute, autoimmune (notably Hashimoto’s thyroiditis), and drug-induced thyroid inflammation. Finally, E07 accounts for other thyroid disorders like hypersecretion of calcitonin and dyshormogenetic goiter, as well as unspecified and complex thyroid abnormalities such as sick-euthyroid syndrome.
