CPT® Code 83915

The CPT® Code 83915 refers to a laboratory test that measures the levels of 5'-nucleotidase (5'-NT) in the blood. This enzyme is produced primarily by the liver and plays a role in various metabolic processes. The measurement of 5'-NT levels is significant in the clinical setting as elevated levels can indicate underlying liver conditions. Specifically, increased 5'-NT levels may be associated with cholestasis, which is a condition characterized by impaired bile flow, liver disease or damage, hepatitis, and the presence of liver tumors. The test is performed by obtaining a blood sample through a procedure known as venipuncture, which is separately reportable. The serum obtained from the blood sample is then analyzed using a quantitative enzymatic methodology, allowing for precise measurement of the enzyme levels. This test is crucial for healthcare providers in diagnosing and monitoring liver-related health issues.
