Code Classification

  • Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism
    (D50–D89)
    • Other disorders of blood and blood-forming organs
      (D70-D77)
      • Other and unspecified diseases of blood and blood-forming organs
        (D75)

D75.83 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of thrombocytosis. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Thrombocytosis

Non-specific codes like D75.83 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for thrombocytosis:

  • Use D75.838 for Other thrombocytosis - BILLABLE CODE

  • Use D75.839 for Thrombocytosis, unspecified - BILLABLE CODE

Clinical Information

  • Thrombocythemia, Essential

    a clinical syndrome characterized by repeated spontaneous hemorrhages and a remarkable increase in the number of circulating platelets.

  • Thrombocytosis

    increased numbers of platelets in the peripheral blood. (dorland, 27th ed)

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Patient Education


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.
