Hemorrhagic disord d/t extrinsic circulating anticoagulants

This code represents a bleeding disorder caused by the presence of antibodies that interfere with the normal coagulation cascade, specifically targeting extrinsic clotting factors. These autoantibodies, often referred to as circulating anticoagulants or inhibitors, prolong clotting times and can lead to spontaneous or excessive bleeding. The condition is acquired, not inherited, and is distinct from bleeding caused by therapeutic anticoagulation.

Use this code when documentation clearly indicates a hemorrhagic diathesis resulting from an acquired circulating anticoagulant, such as a lupus anticoagulant or factor inhibitor, that is not iatrogenic. This diagnosis is typically supported by prolonged PTT or PT that does not correct with mixing studies, along with clinical evidence of bleeding.

• Distinguish carefully between intrinsic (e.g., Factor VIII inhibitor) and extrinsic circulating anticoagulants; this code is specific to extrinsic.
• Do not use this code for bleeding due to therapeutic anticoagulant medication; instead, use codes from T45.5X5- for adverse effects of anticoagulants.
• Always look for specific documentation of the type of circulating anticoagulant if available, as more specific codes may exist for certain factor deficiencies with inhibitors.
