CPT® Code 82373

The CPT® Code 82373 refers to the laboratory test for carbohydrate deficient transferrin (CDT), which serves as a significant biomarker for chronic alcohol consumption. This test is particularly relevant in identifying individuals who may be heavy consumers of alcohol, as CDT levels are elevated in those who consume alcohol in excess of 50 grams per day for a duration exceeding two weeks. The presence of CDT in the blood can indicate a pattern of alcohol use that may be detrimental to health. Additionally, this test can be utilized in the evaluation of patients with poorly controlled or uncontrolled diabetes mellitus, aiding in the diagnosis of congenital glycosylation disorders. The testing process involves obtaining a blood sample through venipuncture, which is a procedure that can be reported separately. Following sample collection, the serum is analyzed using electrophoresis for cases related to chronic alcohol use, while affinity chromatography coupled with mass spectrometry is employed for assessing congenital glycosylation. This comprehensive approach ensures accurate detection and diagnosis based on the specific clinical context of the patient.
