Clinical Information
  • (a-nee-mee-a) a condition in which the number of red blood cells is below normal.
  • A condition in which the number of red blood cells is below normal.
  • A disorder characterized by an reduction in the amount of hemoglobin in 100 ml of blood. Signs and symptoms of anemia may include pallor of the skin and mucous membranes, shortness of breath, palpitations of the heart, soft systolic murmurs, lethargy, and fatigability.
  • A reduction in the number of circulating erythrocytes or in the quantity of hemoglobin.
  • A reduction in the number of red blood cells per cu mm, the amount of hemoglobin in 100 ml of blood, and the volume of packed red blood cells per 100 ml of blood. Clinically, anemia represents a reduction in the oxygen-transporting capacity of a designated volume of blood, resulting from an imbalance between blood loss (through hemorrhage or hemolysis) and blood production. Signs and symptoms of anemia may include pallor of the skin and mucous membranes, shortness of breath, palpitations of the heart, soft systolic murmurs, lethargy, and fatigability.
  • If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.your iron might be too low because of
    • heavy periods
    • pregnancy
    • ulcers
    • colon polyps or colon cancer
    • inherited disorders
    • a diet that does not have enough iron, folic acid or vitamin b12
    • blood disorders such as sickle cell anemia and thalassemia, or cancer
    • aplastic anemia, a condition that can be inherited or acquired
    anemia can make you feel weak, cold, dizzy and irritable. It is confirmed with a blood test. Treatment depends on the kind of anemia you have.
  • Subnormal levels or function of erythrocytes, resulting in symptoms of tissue hypoxia.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 285.9 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?
