Primary myelofibrosis, a condition that interferes with the ability of the bone marrow to produce blood cells, is rated under code 7718, below.

• DC 7704: Polycythemia vera is the opposite of anemia. Instead of having too few red blood cells, the bone marrow produces too many red blood cells. This can cause shortness of breath, bleeding, dizziness and many serious symptoms. If this condition causes a serious side effect like high blood pressure, gout, a stroke or a blood clot, then those conditions are rated separately. They must be serious enough to cause a significant decrease in the ability to function in order to qualify for a rating. For example, slightly high blood pressure that does not limit the amount of activity a person can do is not enough for high blood pressure to be rated separately. Polycythemia vera is not curable but can be treated.
• DC 7702: Agranulocytosis (also known as granulopenia and agranulosis) is a condition where the bone marrow does not produce enough white blood cells. This significantly decreases the body’s immune system and makes the body very vulnerable to infection and disease.
• DC 7725: Myelodysplastic syndromes are conditions in which the body does not produce enough of all types of blood cells.
