Coagulation defects, purpura and other hemorrhagic conditions (D65-D69)

ICD-10 codes D65-D69 cover disorders related to blood clotting problems and bleeding conditions, including coagulation defects, purpura, and other hemorrhagic states. These codes are used to classify a wide range of bleeding disorders from rare genetic deficiencies to acquired clotting abnormalities.

This range begins with D65, which codes for disseminated intravascular coagulation (also known as systemic fibrinogenolysis or purpura fulminans), a serious condition where clotting and bleeding happen simultaneously. Codes D66 and D67 specify hereditary deficiencies of clotting factors VIII and IX, commonly called hemophilia A and B. D68 captures other coagulation defects, including von Willebrand disease (types 1, 2, and 3), acquired coagulation factor deficiencies, and thrombophilia such as activated protein C resistance (Factor V Leiden mutation) and prothrombin gene mutations. The D69 series identifies purpura and platelet-related bleeding conditions, including immune thrombocytopenic purpura (ITP), allergic purpura (immunoglobulin A vasculitis), and other primary or secondary thrombocytopenias. These codes help healthcare providers and coders document specific bleeding disorders like Evans syndrome, posttransfusion purpura, and hereditary platelet function defects, ensuring precise diagnosis and management.
