## **What is HCPCS code G0249?** HCPCS code G0249 has a code description of: Provision of test materials and equipment for home INR monitoring of patient with either mechanical heart valve(s), chronic atrial fibrillation, or venous thromboembolism who meets Medicare coverage criteria; includes: provision of materials for use in the home and reporting of test results to physician; testing not occurring more frequently than once a week; billing units of service include 4 tests. This code is for the provision of materials and equipment for home International Normalized Ratio (INR) monitoring. It is specifically for patients with mechanical heart valve(s), chronic atrial fibrillation, or venous thromboembolism who meet Medicare coverage criteria. This code includes providing the home INR monitoring device and test materials to the patient, as well as the reporting of test results to a physician. It is typically billed by qualified health care professionals like physicians, nurse practitioners, or suppliers coordinating the monitoring process and helps patients monitor coagulation status remotely, reducing the need for frequent clinic visits while maintaining safety and therapeutic effectiveness.

## **HCPCS code G0249 documentation requirements** For a successful claim, documentation must support the medical necessity of home INR monitoring and verify that the patient meets Medicare's coverage criteria. Key requirements include: - **Prescription**: The home monitoring device and testing must be prescribed by the treating physician. The device information must also be noted down. - **Medical necessity**: The patient must have one of the covered conditions: mechanical heart valve(s), chronic atrial fibrillation, or venous thromboembolism. - **Anticoagulation therapy**: The patient must have been on anticoagulation therapy for at least three months before starting home INR monitoring. - **Patient training**: The patient (or caregiver) must have undergone a face-to-face educational program on anticoagulation management and the correct use of the device. This training, including the date, should be documented. - **Continued use**: The documentation should show that the patient continues to correctly use the device for managing their anticoagulation therapy. - **Result reporting**: The patient's health records must include when and how the four home INR test results were reported to the physician.

## **G0249 billing requirements** Billing for G0249 requires adherence to specific rules to ensure proper reimbursement, such as the following: - **Prior approval**: In order to qualify for Medicare coverage, documentation must include prior approval of home INR testing for specific diagnoses like chronic atrial fibrilllation, mechanical heart valves, etc. - **Unit of service**: One unit of G0249 represents the provision of materials for four home INR tests. The billing date of service is the date on which the fourth test is completed and reported to the provider. - **Frequency**: The service is payable no more than once every four weeks. Self-testing should not occur more frequently than once per week. - Included services: The payment for G0249 includes the cost of the device and supplies and should not be billed separately. - **Partial billing**: In rare cases where a patient stops home testing before completing four tests (e.g., due to death or transferring to a Medicare Advantage plan), partial billing is allowed. This requires appending modifier -52 (reduced services) and documenting the number of tests completed. The charge should be reduced proportionally.
