Question: In a patient who was reported to have venous thrombosis, our physician has documented a diagnosis of heparin induced thrombocytopenia. Do we request that our physician confirm the diagnosis? How do we report the thrombosis?

Answer: Your physician may be correct to diagnose heparin induced thrombocytopenia in a patient who develops venous thrombosis. Check the documentation, and make sure the use of heparin is mentioned clearly.
Pick up a specific code: ICD-10-CM offers a specific code for this condition. Report code D75.82 (Heparin-induced thrombocytopenia [HIT]) for thrombocytopenia induced by heparin administration.
What is Heparin induced thrombocytopenia? Heparin induced thrombocytopenia is a distinct clinical entity. It is a relatively common life-threatening clinical condition that occurs in 3-5 percent of all patients receiving unfractionated heparin for at least 5 days. Heparin induced thrombocytopenia has a distinct clinical presentation that is different from other drug-induced thrombocytopenias. Patients may present with arterial or venous thrombosis, such as deep vein thrombosis, pulmonary embolism, stroke, or myocardial infarction.
Note: Transfusion of platelets is generally contraindicated in heparin induced thrombocytopenia. Your physician will switch the patient to an alternative anticoagulant.
