CPT® Code 82383

The CPT® Code 82383 refers to the measurement of catecholamines in the blood. Catecholamines are a group of hormones produced by the adrenal glands and certain nerve tissues, including the brain. The primary catecholamines include dopamine, norepinephrine, and epinephrine (commonly known as adrenaline). These hormones play a crucial role in the body's response to stress and are involved in various physiological processes, such as regulating heart rate, blood pressure, and metabolism. Elevated levels of catecholamines in the blood can indicate the presence of neuroendocrine tumors, such as pheochromocytoma or neuroblastoma, which may require further investigation and management. The test for catecholamines can be performed using a blood sample obtained through venipuncture, and it is essential for the patient to be in a calm and supine position for at least 30 minutes prior to the blood draw to ensure accurate results. The analysis of the blood sample is conducted using quantitative high-performance liquid chromatography, a precise method that allows for the accurate measurement of catecholamine levels in the bloodstream.
