CPT® Code 82160

The CPT® Code 82160 refers to a laboratory test specifically designed to measure the levels of androsterone in the body. Androsterone is classified as an endogenous steroid hormone, which means it is naturally produced within the body. It is known for its weak androgenic effects, which are related to male characteristics and reproductive activity. Additionally, androsterone plays a role in modulating GABA receptors, which are critical for inhibitory neurotransmission in the brain, and it possesses anticonvulsive properties that may help in managing seizure disorders. Elevated levels of androsterone can be indicative of certain medical conditions, such as Cushing's syndrome, a disorder characterized by excessive cortisol production. For accurate results, it is essential that patients refrain from taking adrenocorticotropic hormone (ACTH), steroids, and gonadotropins for at least 48 hours prior to the test. The test itself involves obtaining a blood sample through a procedure known as venipuncture, which is separately reportable. The serum or plasma obtained from the blood sample is then analyzed using a technique called radioimmunoassay, a sensitive method for measuring hormone levels in the laboratory.
