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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

G0248 billing questions
How does G0248 differ from G0249?
G0248 covers a demonstration session and instruction in using the home INR monitoring system. G0249 covers provision of home-testing equipment and materials.
Is G0248 reported for each home INR test?
No. G0248 is reported for a demonstration session, not for each test the patient performs at home.
Does G0248 include interpretation of the INR result?
No. G0248 is technical-component-only; a separate code covers interpretation. G0250 addresses physician review and management of home INR results.
What documentation supports G0248?
Document who received the instruction, the monitor-use training provided, and the clinical context supporting Medicare coverage.
Can every patient using warfarin receive Medicare payment for G0248?
No. Coverage is restricted, so payment is limited to specific circumstances.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
