It may be caused by too little iodine in the diet or by other conditions. Most goiters are not cancer. Enlargement of the THYROID GLAND that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (HYPOTHYROIDISM), or hormone overproduction (HYPERTHYROIDISM). Goiter may be congenital or acquired, sporadic or endemic (GOITER, ENDEMIC). 240.9 is a specific code that can be used to specify a diagnosis 240.9 contains 11 index entries View the ICD-9-CM Volume 1 240.* hierarchy Alternate Terminology Enlargement of thyroid Goiter or struma: NOS diffuse colloid endemic hyperplastic nontoxic (diffuse) parenchymatous sporadic 240.9 Excludes congenital (dyshormonogenic) goiter (246.1)  Index entries containing 240.9: Bronchocele meaning goiter 240.9 Cyst (mucus) (retention) (serous) (simple) thyroid (gland) 246.2 colloid (see also Goiter) 240.9 Enlargement, enlarged - see also Hypertrophy thyroid (gland) (see also Goiter) 240.9 Goiter (adolescent) (colloid) (diffuse) (dipping) (due to iodine deficiency) (endemic) (euthyroid) (heart) (hyperplastic) (internal) (intrathoracic) (juvenile) (mixed type) (nonendemic) (parenchymatous) (plunging) (sporadic) (subclavicular) (substernal) 240.9 with hyperthyroidism (recurrent) (see also Goiter, toxic) 242.0 thyrotoxicosis (see also Goiter, toxic) 242.0 adenomatous (see also Goiter, nodular) 241.9 cancerous (M8000/3) 193 complicating pregnancy, childbirth, or puerperium 648.1 congenital 246.1 cystic (see also Goiter, nodular) 241.9 due to enzyme defect in synthesis of thyroid hormone (butane-insoluble iodine) (coupling) (deiodinase) (iodide trapping or organification) (iodotyrosine dehalogenase) (peroxidase) 246.1 dyshormonogenic 246.1 exophthalmic (see also Goiter, toxic) 242.0 familial (with deaf-mutism) 243 fibrous 245.3 lingual 759.2 lymphadenoid 245.2 malignant (M8000/3) 193 multinodular (nontoxic) 241.1 toxic or with hyperthyroidism (see also Goiter, toxic) 242.2 nodular (nontoxic) 241.9 with hyperthyroidism (see also Goiter, toxic) 242.3 thyrotoxicosis (see also Goiter, toxic) 242.3 endemic 241.9 exophthalmic (diffuse) (see also Goiter, toxic) 242.0 multinodular (nontoxic) 241.1 sporadic 241.9 toxic (see also Goiter, toxic) 242.3 uninodular (nontoxic) 241.0 nontoxic (nodular) 241.9 multinodular 241.1 uninodular 241.0 pulsating (see also Goiter, toxic) 242.0 simple 240.0 toxic 242.0 adenomatous 242.3 multinodular 242.2 uninodular 242.1 multinodular 242.2 nodular 242.3 multinodular 242.2 uninodular 242.1 uninodular 242.1 uninodular (nontoxic) 241.0 toxic or with hyperthyroidism (see also Goiter, toxic) 242.1 Hyperplasia, hyperplastic thyroid (see also Goiter) 240.9 primary 242.0 secondary 242.2 Hypertrophy, hypertrophic thyroid (gland) (see also Goiter) 240.9 primary 242.0 secondary 242.2 Mass substernal 786.6 thyroid (see also Goiter) 240.9 Struma (see also Goiter) 240.9 fibrosa 245.3 Hashimoto (struma lymphomatosa) 245.2 lymphomatosa 245.2 nodosa (simplex) 241.9 endemic 241.9 multinodular 241.1 sporadic 241.9 toxic or with hyperthyroidism 242.3 multinodular 242.2 uninodular 242.1 toxicosa 242.3 multinodular 242.2 uninodular 242.1 uninodular 241.0 ovarii (M9090/0) 220 and carcinoid (M9091/1) 236.2 malignant (M9090/3) 183.0 Riedel's (ligneous thyroiditis) 245.3 scrofulous (see also Tuberculosis) 017.2 tuberculous (see also Tuberculosis) 017.2 abscess 017.2 adenitis 017.2 lymphangitis 017.2 ulcer 017.2 Substernal thyroid (see also Goiter) 240.9 congenital 759.2 Thyrocele (see also Goiter) 240.9 Thyromegaly 240.9
