HCPCS code G0248: Home INR training, monitor use demonstration2026 Medicare rate & RVUs

Medicare pays $105.55 for G0248 nationally in the office. Local office rates run $90.09–$150.69.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What G0248 covers

G0248 reports a session demonstrating a home INR monitoring system and instructing a patient or caregiver in its use. It is associated with home prothrombin-time/INR testing for a patient managed with warfarin. The demonstration may include showing how to use the system and obtain a test result. G0248 describes the training session, not the patient's recurring tests at home, the supply of testing equipment, or ongoing review of results.

Report the service per demonstration session and document who received the instruction, what monitor-use training was provided, and the clinical context supporting Medicare coverage. CMS classifies coverage as restricted, so payment is limited to specific circumstances. G0248 is technical-component-only; a separate code covers interpretation. G0249 addresses provision of home-testing equipment and materials, while G0250 addresses physician review and management of home INR results.
