Heparin induced thrombocytopenia (HIT) D75. 82 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM D75. 82 became effective on October 1, 2021.
ICD-10 | Heparin induced thrombocytopenia (HIT) (D75. 82)
Heparin‐induced thrombocytopenia (HIT) is a potentially devastating immune mediated adverse drug reaction caused by the emergence of antibodies that activate platelets in the presence of heparin.
Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant.
Heparin-induced thrombocytopenia (HIT) is a life-threatening condition that can happen to some people after they take a medicine called heparin, a blood-thinning drug that helps prevent clots.
Heparin belongs to a class of drugs called Anticoagulants, Cardiovascular, Anticoagulants, Hematologic.
Type 2 HIT is an immune-mediated disorder that typically occurs 4-10 days after exposure to heparin and has life- and limb-threatening thrombotic complications. In general medical practice, the term HIT refers to type 2 HIT.
HIT is primarily a disease of hospitalized or recently discharged patients from the hospital. HIT occurs in 0.5% to 1% of patients exposed to unfractionated heparin for medical and surgical indications. The incidence is markedly lower (0.1%–0.5%) in patients receiving LMWH (low molecular weight heparin).
HIT happens when your body's immune system reacts to heparin. This causes changes in your blood. Some people have no symptoms of HIT. But it may cause a dangerous clot to form in blood vessels.
Diagnosis of HIT is based on clinical assessment and laboratory results. Primary laboratory tests for HIT include immunologic assays, such as an enzyme-linked immunosorbent assay (ELISA), and functional, platelet-activation assays, such as the serotonin release assay (SRA).
Heparin-induced thrombocytopenia (HIT) is an uncommon but potentially devastating complication of anticoagulation with unfractionated heparin (UFH) or low-molecular-weight heparin (LMWH).
A test for heparin-induced thrombocytopenia (HIT) antibody, also called heparin-PF4 antibody, is performed to detect antibodies that develop in some people who have been treated with heparin.
Macrocytosis is the enlargement of red blood cells with near-constant hemoglobin concentration, and is defined by a mean corpuscular volume (MCV) of greater than 100 femtolitres (the precise criterion varies between laboratories). The enlarged erythrocytes are called macrocytes or megalocytes (both words have roots meaning "big cell").

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 289.84 was previously used, D75.82 is the appropriate modern ICD10 code.
Heparin-induced thrombocytopenia ( HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel) because platelets release microparticles ...
Gradually, evidence accumulated on the exact underlying mechanism. In 1984–1986, John G. Kelton and colleagues at McMaster University Medical School developed the laboratory tests that could be used to confirm or exclude heparin-induced thrombocytopenia.

These antibodies are usually of the IgG class and their development usually takes about 5 days . However, those who have been exposed to heparin in the last few months may still have circulating IgG, as IgG-type antibodies generally continue to be produced even when their precipitant has been removed. This is similar to immunity against certain microorganisms, with the difference that the HIT antibody does not persist more than three months. HIT antibodies have been found in individuals with thrombocytopenia and thrombosis who had no prior exposure to heparin, but the majority are found in people who are receiving heparin.
Heparin may be used for both prevention and the treatment of thrombosis. It exists in two main forms: an "unfractionated" form that can be injected under the skin (subcutaneously) or through an intravenous infusion, and a "low molecular weight" form that is generally given subcutaneously. Commonly used low molecular weight heparins are enoxaparin, dalteparin, nadroparin and tinzaparin.
Typically, the platelet count falls 5–14 days after heparin is first given; if someone has received heparin in the previous three months, the fall in platelet count may occur sooner, sometimes within a day.
These include fever, chills, high blood pressure, a fast heart rate, shortness of breath, and chest pain. This happens in about a quarter of people with HIT.
