2008 ICD-9-CM Diagnosis 244.9

Unspecified acquired hypothyroidism

  • A condition in which the production of thyroid hormone by the thyroid gland is diminished. Signs and symptoms of hypothyroidism include low metabolic rate, tendency to weight gain, somnolence and sometimes myxedema. In the United States, the most common cause of hypothyroidism is Hashimoto's thyroiditis, an autoimmune disorder. SYN athyrea. --2004
  • The clinical syndrome that results from decreased secretion of thyroid hormone from the thyroid gland. It leads to a slowing of metabolic processes and in its most severe form to the accumulation of mucopolysaccharides in the skin, causing a nonpitting edema termed myxedema. Cretinism is the congenital form leading to abnormalities of intellectual and physical development. (Bennett, et al., Cecil Textbook of Medicine, 20th ed)
  • Too little thyroid hormone. Symptoms include weight gain, constipation, dry skin, and sensitivity to the cold. Also called underactive thyroid.
