Clinical Information

• Anemia

  a reduction in the number of circulating erythrocytes or in the quantity of hemoglobin.

• Anemia, Aplastic

  a form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.

• Anemia, Diamond-Blackfan

  a rare congenital hypoplastic anemia that usually presents early in infancy. the disease is characterized by a moderate to severe macrocytic anemia, occasional neutropenia or thrombocytosis, a normocellular bone marrow with erythroid hypoplasia, and an increased risk of developing leukemia. (curr opin hematol 2000 mar;7(2):85-94)

• Anemia, Dyserythropoietic, Congenital

  a familial disorder characterized by anemia with multinuclear erythroblasts, karyorrhexis, asynchrony of nuclear and cytoplasmic maturation, and various nuclear abnormalities of bone marrow erythrocyte precursors (erythroid precursor cells). type ii is the most common of the 3 types; it is often referred to as hempas, based on the hereditary erythroblast multinuclearity with positive acidified serum test.

• Anemia, Hemolytic

  a condition of inadequate circulating red blood cells (anemia) or insufficient hemoglobin due to premature destruction of red blood cells (erythrocytes).

• Anemia, Hemolytic, Autoimmune

  acquired hemolytic anemia due to the presence of autoantibodies which agglutinate or lyse the patient's own red blood cells.

• Anemia, Hemolytic, Congenital

  hemolytic anemia due to various intrinsic defects of the erythrocyte.

• Anemia, Hemolytic, Congenital Nonspherocytic

  any one of a group of congenital hemolytic anemias in which there is no abnormal hemoglobin or spherocytosis and in which there is a defect of glycolysis in the erythrocyte. common causes include deficiencies in glucose-6-phosphate isomerase; pyruvate kinase; and glucose-6-phosphate dehydrogenase.

• Anemia, Hypochromic

  anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. the individual cells contain less hemoglobin than they could have under optimal conditions. hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. it can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions. (stedman, 25th ed; from miale, laboratory medicine: hematology, 6th ed, p393)

• Anemia, Hypoplastic, Congenital

  an inborn condition characterized by deficiencies of red cell precursors that sometimes also includes leukopenia and thrombocytopenia.

• Anemia, Iron-Deficiency

  anemia characterized by decreased or absent iron stores, low serum iron concentration, low transferrin saturation, and low hemoglobin concentration or hematocrit value. the erythrocytes are hypochromic and microcytic and the iron binding capacity is increased.

• Anemia, Macrocytic

  anemia characterized by larger than normal erythrocytes, increased mean corpuscular volume (mcv) and increased mean corpuscular hemoglobin (mch).

• Anemia, Megaloblastic

  a disorder characterized by the presence of anemia, abnormally large red blood cells (megalocytes or macrocytes), and megaloblasts.

• Anemia, Myelophthisic

  anemia characterized by appearance of immature myeloid and nucleated erythrocytes in the peripheral blood, resulting from infiltration of the bone marrow by foreign or abnormal tissue.

• Anemia, Neonatal

  the mildest form of erythroblastosis fetalis in which anemia is the chief manifestation.

• Anemia, Pernicious

  a megaloblastic anemia occurring in children but more commonly in later life, characterized by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin b 12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. (dorland, 27th ed)

• Anemia, Refractory

  a severe sometimes chronic anemia, usually macrocytic in type, that does not respond to ordinary antianemic therapy.

• Anemia, Refractory, with Excess of Blasts

  chronic refractory anemia with granulocytopenia, and/or thrombocytopenia. myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells.

• Anemia, Sickle Cell

  a disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. it is the clinical expression of homozygosity for hemoglobin s.

• Anemia, Sideroblastic

  anemia characterized by the presence of erythroblasts containing excessive deposits of iron in the marrow.

• beta-Thalassemia

  a disorder characterized by reduced synthesis of the beta chains of hemoglobin. there is retardation of hemoglobin a synthesis in the heterozygous form (thalassemia minor), which is asymptomatic, while in the homozygous form (thalassemia major, cooley's anemia, mediterranean anemia, erythroblastic anemia), which can result in severe complications and even death, hemoglobin a synthesis is absent.

• Equine Infectious Anemia

  viral disease of horses caused by the equine infectious anemia virus (eiav; infectious anemia virus, equine). it is characterized by intermittent fever, weakness, and anemia. chronic infection consists of acute episodes with remissions.

• Fanconi Anemia

  congenital disorder affecting all bone marrow elements, resulting in anemia; leukopenia; and thrombopenia, and associated with cardiac, renal, and limb malformations as well as dermal pigmentary changes. spontaneous chromosome breakage is a feature of this disease along with predisposition to leukemia. there are at least 7 complementation groups in fanconi anemia: fanca, fancb, fancc, fancd1, fancd2, fance, fancf, fancg, and fancl. (from online mendelian inheritance in man, http://www.ncbi.nlm.nih.gov/entrez/dispomim.cgi?id=227650, august 20, 2004)

• Hypersplenism

  condition characterized by splenomegaly, some reduction in the number of circulating blood cells in the presence of a normal or hyperactive bone marrow, and the potential for reversal by splenectomy.

• Normocytic Anemia

  anemia in which the red blood cell volume is normal.

D64.9 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
811	RED BLOOD CELL DISORDERS WITH MCC	16	1.4036
812	RED BLOOD CELL DISORDERS WITHOUT MCC	16	0.9007

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Patient Education

Anemia

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.

Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

Conditions that may lead to anemia include:

• 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
• G6PD deficiency, a metabolic disorder

Anemia can make you feel tired, cold, dizzy, and irritable. You may be short of breath or have a headache.

Your doctor will diagnose anemia with a physical exam and blood tests. Treatment depends on the kind of anemia you have.
