Long term (current) use of anticoagulants

This diagnosis code indicates that a patient is currently and continuously taking anticoagulant medication. This is typically for the prevention or treatment of thrombotic events, such as deep vein thrombosis or pulmonary embolism, or in conditions like atrial fibrillation. It signifies an ongoing therapeutic regimen rather than a one-time or short-term prescription.

Apply this code when documenting a patient's active, long-term use of anticoagulant drugs, such as warfarin, dabigatran, rivaroxaban, apixaban, or enoxaparin. This is appropriate for patients on maintenance therapy to prevent future clots or manage existing chronic conditions requiring anticoagulation. It should be used in conjunction with the code for the underlying condition necessitating the anticoagulant.

• Always code the underlying condition requiring the long-term anticoagulant therapy first, followed by this Z code.
• Do not use this code for short-term prophylactic anticoagulation (e.g., post-surgical prophylaxis for a few days or weeks).
• Ensure documentation clearly states "long-term" or "current use" of anticoagulants to support the use of this code.
