In simple words: An overactive thyroid gland produces too much thyroid hormone, causing a condition called thyrotoxicosis or hyperthyroidism. This can lead to symptoms like nervousness, weight loss, and a rapid heartbeat.

Thyrotoxicosis, also known as hyperthyroidism, is a condition caused by excessive thyroid hormone production by the thyroid gland. This leads to a sped-up metabolism and a variety of symptoms.

Example 1: A 35-year-old female presents with anxiety, weight loss despite increased appetite, heat intolerance, and palpitations. Blood tests reveal low TSH and elevated T4 and T3, confirming thyrotoxicosis., A 60-year-old male experiences unexplained weight loss, tremors, and atrial fibrillation. After further investigation, including thyroid function tests, he is diagnosed with thyrotoxicosis secondary to a toxic multinodular goiter., A 28-year-old female, recently postpartum, experiences symptoms of anxiety, insomnia, and rapid heart rate. Her doctor suspects postpartum thyroiditis, and subsequent blood tests confirm transient thyrotoxicosis.

Documentation should include patient history, physical exam findings, thyroid function test results (TSH, T3, T4, and possibly thyroglobulin), and any imaging or biopsy results. The cause of thyrotoxicosis, such as Graves' disease or toxic nodular goiter, should also be documented if known.

** Thyrotoxicosis can be primary, originating in the thyroid gland itself, or secondary, caused by a problem in the pituitary gland. The term "thyrotoxicosis" is sometimes used interchangeably with "hyperthyroidism," although thyrotoxicosis is a broader term as it encompasses all states of thyroid hormone excess regardless of the source.iFrameAI can provide more comprehensive and up-to-date information regarding medical codes, billing practices, and clinical guidelines.
