Disease Synonyms
  • Polycythemia vera (clinical)
Clinical Information
  • A chronic myeloproliferative disorder characterized by an increased red blood cell production. Excessive proliferation of the myeloid lineage is observed as well. The major symptoms are related to hypertension or to vascular abnormalities caused by the increased red cell mass. The cause is unknown. With currently available treatment, the median survival exceeds 10 years. (who, 2001)
  • A chronic myeloproliferative neoplasm characterized by an increased red blood cell production. Excessive proliferation of the myeloid lineage is observed as well. The major symptoms are related to hypertension or to vascular abnormalities caused by the increased red cell mass. The cause is unknown. With currently available treatment, the median survival exceeds 10 years. (who, 2001)
  • A condition that produces excessive red blood cells
  • A disease in which there are too many red blood cells in the bone marrow and blood, causing the blood to thicken. The number of white blood cells and platelets may also increase. The extra blood cells may collect in the spleen and cause it to become enlarged. They may also cause bleeding problems and make clots form in blood vessels.
  • A myeloproliferative disorder of unknown etiology, characterized by abnormal proliferation of all hematopoietic bone marrow elements and an absolute increase in red cell mass and total blood volume, associated frequently with splenomegaly, leukocytosis, and thrombocythemia. Hematopoiesis is also reactive in extramedullary sites (liver and spleen). In time myelofibrosis occurs.
  • Myeloproliferative disorder characterized by abnormal proliferation of all hematopoietic bone marrow elements and an absolute increase in red cell mass and total blood volume; associated frequently with splenomegaly, leukocytosis, and thrombocythemia.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 238.4 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
