CPT® Code 85396

Coagulation/fibrinolysis assay, whole blood (eg, viscoelastic clot assessment), including use of any pharmacologic additive(s), as indicated, including interpretation and written report, per day

The CPT® Code 85396 refers to a coagulation/fibrinolysis assay performed on whole blood, which is a laboratory test designed to evaluate the body's ability to form and dissolve blood clots. This assay utilizes pharmacologic additives as necessary to enhance the assessment process. The primary purpose of this test is to provide a comprehensive evaluation of a patient's risk for hemorrhage or thrombosis by measuring various components involved in the clotting cascade. Key elements assessed include the rate of clot formation, the strength of the clot, and its stability, which are determined through the analysis of fibrin formation, platelet function, and fibrinolytic activity. The whole blood assay is particularly valuable in clinical scenarios involving acute bleeding or major trauma, as it offers a broad perspective on hemostatic imbalances that may be present. This information is crucial for guiding appropriate transfusion support and other therapeutic interventions. The test is conducted by obtaining a blood sample, which can be collected through a separately reportable venipuncture, arterial draw, or central line draw. The analysis is performed using thromboelastogram (TEG) techniques, specifically with the addition of plain kaolin and heparinase to the whole blood sample. Following the assay, a written report is generated by a pathologist or another qualified professional, detailing patient-specific diagnostic information, treatment strategies, and recommendations for future testing options.
