CPT® Code 82530

Cortisol is a glucocorticoid, which is a type of steroid hormone produced by the adrenal glands, particularly in response to stress. This hormone plays a crucial role in various bodily functions, including the regulation of blood glucose levels, suppression of the immune system, and the metabolism of fats, proteins, and carbohydrates. The measurement of cortisol levels is significant in diagnosing certain medical conditions. Specifically, elevated cortisol levels may indicate Cushing syndrome, while decreased levels may suggest Addison disease. The CPT® Code 82530 refers to a specific laboratory test that measures free cortisol, also known as hydrocortisone, in urine. This test is typically conducted using a 24-hour urine collection or a random urine sample, which is collected as a separately reportable procedure. The analysis of the urine sample is performed using advanced techniques such as quantitative liquid chromatography-tandem mass spectrometry, ensuring accurate measurement of free cortisol levels in the body.
