| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
R71.8 is a billable ICD-10 code used to specify a medical diagnosis of other abnormality of red blood cells. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

Clinical Information
- Heinz Bodies-. abnormal intracellular inclusions, composed of denatured hemoglobin, found on the membrane of red blood cells. they are seen in thalassemias, enzymopathies, hemoglobinopathies, and after splenectomy.
- Erythrocyte Aggregation-. the formation of clumps of red blood cells under low or non-flow conditions, resulting from the attraction forces between the red blood cells. the cells adhere to each other in rouleaux aggregates. slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. stronger or weaker than normal aggregation may result from a variety of effects in the erythrocyte membrane or in blood plasma. the degree of aggregation is affected by erythrocyte deformability, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. blood viscosity and the erythrocyte sedimentation rate are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.
- HELLP Syndrome-. a syndrome of hemolysis, elevated liver enzymes, and low blood platelets count (thrombocytopenia). hellp syndrome is observed in pregnant women with pre-eclampsia or eclampsia who also exhibit liver damage and abnormalities in blood coagulation.
- Hemolysis-. the destruction of erythrocytes by many different causal agents such as antibodies, bacteria, chemicals, temperature, and changes in tonicity.
- Erythrocytes-. red blood cells. mature erythrocytes are non-nucleated, biconcave disks containing hemoglobin whose function is to transport oxygen.
- Anisopoikilocytosis-. a test result indicating the presence of red cells of various sizes and shapes in the peripheral blood.
- Hereditary Pyropoikilocytosis-. an autosomal recessive inherited severe hemolytic anemia. it is a subtype of hereditary elliptocytosis and is characterized by partial spectrin deficiency.
- Mild to Moderate Anisopoikilocytosis-. a test result indicating a mild to moderate degree of anisopoikilocytosis in the peripheral blood.
- Poikilocytosis-. an increase in the number of abnormally shaped red blood cells.
- Hereditary Spherocytosis-. an autosomal dominant inherited disorder characterized by the presence of smaller than normal, sphere-shaped erythrocytes. it results in hemolytic anemia and splenomegaly.
