Platelets are small bits of cells in the blood that help stop bleeding and form blood clots.

• DC 7705: Thrombocytopenia is a condition where the platelet count in the blood is low. The normal amount of platelets in a microliter of blood is between 150,000 to 450,000.
• DC 7718: Essential thrombocythemia is a disease which causes the body to produce too many platelets, and primary myelofibrosis is a condition that interferes with the ability of the bone marrow to produce blood cells, thus resulting in abnormal cell and platelet levels. Both are rated under this code.
