2021 ICD-10-CM Codes for Thyrotoxicosis [hyperthyroidism] (E05)

Clinical Terms for Thyrotoxicosis [hyperthyroidism] (E05)

Thyrotoxicosis-. A hypermetabolic syndrome caused by excess THYROID HORMONES which may come from endogenous or exogenous sources. The endogenous source of hormone may be thyroid HYPERPLASIA; THYROID NEOPLASMS; or hormone-producing extrathyroidal tissue. Thyrotoxicosis is characterized by NERVOUSNESS; TACHYCARDIA; FATIGUE; WEIGHT LOSS; heat intolerance; and excessive SWEATING.

Hyperthyroidism-. Hypersecretion of THYROID HORMONES from the THYROID GLAND. Elevated levels of thyroid hormones increase BASAL METABOLIC RATE.
