Code Classification

  • Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism
    • Coagulation defects, purpura and other hemorrhagic conditions
      • Purpura and other hemorrhagic conditions

D69.6 is a billable diagnosis code used to specify a medical diagnosis of thrombocytopenia, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like D69.6 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Isolated thrombocytopenia
  • Macrothrombocytopenia with mitral valve insufficiency
  • Refractory thrombocytopenia

Clinical Information

  • Jacobsen Distal 11q Deletion Syndrome-. a clinically recognized congenital malformation condition caused by a distal 11q deletion. the features of the syndrome are growth retardation, psychomotor retardation, trigonocephaly, divergent intermittent strabismus, epicanthus, telecanthus, broad nasal bridge, short nose with anteverted nostrils, carp-shaped upper lip, retrognathia, low-set dysmorphic ears, bilateral camptodactyly, and hammertoes. platelet dysfunction is a feature in paris-trousseau type thrombocytopenia.
  • Kasabach-Merritt Syndrome-. rapidly growing vascular lesion along the midline axis of the neck, upper trunk, and extremities that is characterized by consumption coagulopathy; thrombocytopenia; and hemolytic anemia. it is often associated with infantile kaposiform hemangioendothelioma and other vascular tumors such as tufted angioma.
  • Purpura, Thrombocytopenic, Idiopathic-. thrombocytopenia occurring in the absence of toxic exposure or a disease associated with decreased platelets. it is mediated by immune mechanisms, in most cases immunoglobulin g autoantibodies which attach to platelets and subsequently undergo destruction by macrophages. the disease is seen in acute (affecting children) and chronic (adult) forms.
  • Thrombocytopenia-. a subnormal level of blood platelets.
  • Thrombocytopenia, Neonatal Alloimmune-. a condition in newborns caused by immunity of the mother to platelet alloantigens on the fetal platelets. the platelets, coated with maternal antibodies, are destroyed and removed by the fetal mononuclear phagocyte system. affected infants may have intracranial hemorrhages.
  • Blood Platelets-. non-nucleated disk-shaped cells formed in the megakaryocyte and found in the blood of all mammals. they are mainly involved in blood coagulation.
  • Anasarca-. a condition that is characterized by the presence of generalized edema. causes include congestive heart failure, liver failure, renal failure, and severe malnutrition.

Platelet Disorders

Platelets, also known as thrombocytes, are blood cells. They form in your bone marrow, a sponge-like tissue in your bones. Platelets play a major role in blood clotting. Normally, when one of your blood vessels is injured, you start to bleed. Your platelets will clot (clump together) to plug the hole in the blood vessel and stop the bleeding. You can have different problems with your platelets:

  • If your blood has a low number of platelets, it is called thrombocytopenia. This can put you at risk for mild to serious bleeding. The bleeding could be external or internal. There can be various causes. If the problem is mild, you may not need treatment. For more serious cases, you may need medicines or blood or platelet transfusions.
  • If your blood has too many platelets, you may have a higher risk of blood clots.
    • When the cause is unknown, this is called thrombocythemia. It is rare. You may not need treatment if there are no signs or symptoms. In other cases, people who have it may need treatment with medicines or procedures.
    • If another disease or condition is causing the high platelet count, it is thrombocytosis. The treatment and outlook for thrombocytosis depends on what is causing it.
  • Another possible problem is that your platelets do not work as they should. For example, in von Willebrand Disease, your platelets cannot stick together or cannot attach to blood vessel walls. This can cause excessive bleeding. There are different types of in von Willebrand Disease; treatment depends on which type you have.

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
