CPT® Code 82088

The CPT® Code 82088 refers to the measurement of aldosterone levels through a blood or urine test. Aldosterone is a crucial hormone produced in the adrenal cortex, playing a significant role in regulating blood volume and blood pressure. It achieves this by controlling the concentrations of sodium and potassium in the bloodstream. The secretion of aldosterone is intricately regulated by two other proteins: renin and angiotensin. When assessing aldosterone levels, it is common practice to also conduct separate tests for these proteins, as they provide important context for interpreting aldosterone results. For the blood test, a sample is typically collected via venipuncture, with specific timing recommendations suggesting that the sample be drawn between 10 AM and noon. The patient should be in a supine position for two hours prior to the test or alternatively, in an upright position for the same duration. The serum obtained from the blood sample is then analyzed using a method known as radioimmunoassay. In addition to the blood test, a 24-hour urine collection is required, where a 10 ml sample is submitted for analysis. It is essential to document the total volume of urine voided during the collection period and the exact time of collection, as this information is critical for accurate testing. The urine sample is also tested using radioimmunoassay, ensuring a comprehensive evaluation of aldosterone levels in the body.
