CPT® Code 93740

Temperature gradient studies, identified by CPT® Code 93740, are diagnostic procedures utilized to assess the functionality and health of the heart and circulatory system. This evaluation is achieved through the measurement of temperature differences within the blood vessels, which can provide critical insights into vascular health. During the procedure, an intravenous catheter is carefully advanced into the specific blood vessels that require examination. This catheterization allows for the precise measurement of intravascular temperatures at the internal walls of the blood vessels. By comparing these temperature readings, healthcare professionals can identify variations that may indicate underlying circulatory issues. The results of the temperature gradient studies are compiled into a written interpretation, which details the observed temperature variations and their potential implications for the patient's cardiovascular status. This procedure is essential for diagnosing conditions that may affect blood flow and vascular integrity, thereby guiding further clinical decision-making and management strategies.
