About 93793: Warfarin anticoagulation management with INR review
Warfarin management after a new INR result includes interpreting the result, addressing the dose, instructing the patient, and scheduling further testing.
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.

93793 billing questions
Can 93793 be billed more than once in a day if several INR results are reviewed?
No. Report it once per day when the required warfarin management is performed, not once for each result.
Does 93793 include the INR test itself?
No. For a laboratory or office prothrombin time/INR test, 85610 describes the testing service when it is separately reportable. Do not assume specimen collection warrants an additional charge.
Can 93793 be reported on the same day as home INR monitor training?
Do not report 93793 with 93792 on the same date. Code 93792 describes training the patient or caregiver to perform and report home INR testing; it is not the code for ongoing result review and warfarin management.
Who is responsible for the management billed under 93793?
A physician or other qualified health care professional performs the professional review and management. Clinical staff may help obtain results and convey instructions under that professional's direction.
Must the patient be seen in person?
No. Instructions may be conveyed by phone after a new home or laboratory INR result, provided the record supports the interpretation, dosing decision, patient instructions, and further testing plan.
Should modifier 26 or a same-day E/M code be added?
Do not append modifier 26; CMS already designates 93793 as professional-component-only. Do not report an E/M service for the same INR review and dosing work; a distinct E/M service requires separate supporting documentation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
