Ongoing Blood-Thinner Management, Later Months

Arizona rates for HCPCS 99364

This covers the ongoing work involved in managing a patient's warfarin (a blood-thinning medication) for each additional three-month period after the first, in the outpatient setting. It includes reviewing regular blood clotting test results, adjusting the medication dose as needed, giving the patient instructions, and ordering follow-up testing. This reflects the continued coordination needed to keep the blood-thinning level in a safe range over the long term.
