What 93792 covers
This service covers face-to-face instruction for a patient or caregiver beginning home monitoring of prothrombin time through an INR monitor. Training addresses use and care of the device, obtaining a blood sample, and reporting results to the clinician. It is typically provided in an office or similar setting by clinical staff under a physician’s or other qualified health care professional’s direction. A patient already using a home monitor who returns only for anticoagulation management is receiving a different service.
Report 93792 for initiation training, not for each home test or result. Documentation should identify the patient or caregiver trained and support instruction in monitor operation, sample collection, and result reporting. CMS classifies this as a technical-component-only service; interpretation is covered by a separate code. Keep the training service distinct from subsequent review of INR results, dosage instructions, and follow-up management, which may be reported separately when performed and documented.
