*The term "essential" or "primary" means there is no discernable cause for the increase in platelet production.

*Essential thrombocythemia (ET) is a specific, rare chronic blood condition characterised by the overproduction of platelets in the bone marrow. It is classified as one of the Myeloproliferative Disorders. It may, even more rarely, evolve into acute myeloid leukemia or myelofibrosis.

*Essential thrombocythemia (ET) is a rare chronic blood condition characterised by the overproduction of platelets ~~by megakaryocytes~~ in the bone marrow. It may, ~~albeit~~ rarely, ~~develop~~ into acute myeloid leukemia or myelofibrosis. It is ~~one~~ of ~~four myeloproliferative neoplasms (blood cancers~~ that ~~occur when~~ the ~~body makes too~~ many ~~white~~ or ~~red~~ blood ~~cells~~, ~~or platelets)~~.

*The more general term, "thrombocythemia" just refers to elevated platelets. It has many causes and is common in hospitalized patients.

*~~Thrombocythemia~~ is a ~~disorder~~ in which ~~excess platelets are produced, leading to abnormal~~ blood ~~clotting~~ or ~~bleeding.~~

*The most common set of causes are things that stimulate the bone marrow generally, which includes hemorrhage, infection and many other things -- this is called "reactive thrombocythemia"

*Elevated platelets are usually not dangerous or problematic by themselves unless the count is very high, usually >1 million, as it can then increase blood viscosity leading to thromboembolism, strokes, TIA, and other problems of vascular congestion.

*SO, the coding guideline is:

**code [[Essential thrombocythemia/thrombocytosis]] if present

**for other causes/types of elevated platelets, only code it if it has caused a problem (such as a thromboembolism) -- in which case combine the code for the problem + [[Disease of blood or blood-forming organ, NOS]]
