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

What 93793 covers

This service covers management of a patient taking warfarin after a new INR result from home monitoring, an office test, or a laboratory test. A physician or other qualified health care professional reviews and interprets the result, determines whether the warfarin dose should change, ensures the patient receives instructions, and arranges further INR testing. Clinical staff, including anticoagulation clinic nurses, may help communicate and carry out the plan under the billing professional's direction. Patients commonly include those treated for atrial fibrillation, venous thromboembolism, or a mechanical heart valve; the work may occur without an in-person visit.

Report 93793 once per day when the required management is performed, rather than once for each INR value reviewed. Document the new result and its source, the interpretation and dosing decision, patient instructions, and the plan for further testing. CMS designates 93793 as professional-component-only: it represents interpretation and management, while INR testing is a separate service. Do not use an E/M visit code merely to duplicate the same INR review and dosing work.
