CPT® Code 93792

Patient/caregiver training for initiation of home international normalized ratio (INR) monitoring under the direction of a physician or other qualified health care professional, face-to-face, including use and care of the INR monitor, obtaining blood sample, instructions for reporting home INR test results, and documentation of patient's/caregiver's ability to perform testing and report results

The CPT® Code 93792 refers to the process of providing patient or caregiver training for the initiation of home international normalized ratio (INR) monitoring, which is conducted under the direction of a physician or other qualified healthcare professional. This training is performed face-to-face and encompasses several critical components. It includes instruction on the use and care of the INR monitor, which is a portable device designed to measure the time it takes for blood plasma to clot. Additionally, the training covers the procedure for obtaining a blood sample, typically through a finger stick, and provides detailed instructions for reporting the results of home INR tests back to the healthcare provider. A vital aspect of this training is the documentation of the patient's or caregiver's ability to perform the testing and accurately report the results, ensuring that they are competent in managing their anticoagulation therapy at home. The INR monitoring system is particularly important for patients requiring anticoagulation therapy due to conditions such as artificial heart valves, chronic atrial fibrillation, and venous thromboembolism, as it allows for greater flexibility and minimizes the risks associated with improper anticoagulation levels.
