What This Code Means

Other inherited blood clotting disorders that increase the risk of abnormal blood clot formation not classified elsewhere.

Coding Tips

• •Use this code for thrombophilias not specifically listed (e.g., protein S deficiency, protein C deficiency, dysfibrinogenemia)
• •Document the specific type of thrombophilia identified through testing for complete clinical documentation

Clinical Significance

Other primary thrombophilia captures inherited thrombophilic conditions beyond Factor V Leiden and prothrombin gene mutation, including protein C deficiency, protein S deficiency, antithrombin deficiency, and rare conditions like dysfibrinogenemia with thrombotic tendency. Antithrombin deficiency carries the highest thrombotic risk among inherited thrombophilias with a 25-50 fold increase.

Documentation Requirements

• ✓Document the specific thrombophilia identified (protein C, protein S, or antithrombin deficiency), laboratory levels and functional assay results, genetic testing if performed, and personal/family history of thrombotic events.
• ✓Record current anticoagulation therapy and any pregnancy-related considerations, as these conditions significantly impact obstetric management.
