Hereditary elliptocytosis

Hereditary elliptocytosis is an inherited red blood cell disorder characterized by abnormally oval or elliptical-shaped erythrocytes. This morphological defect results from mutations in genes encoding red blood cell membrane proteins, leading to varying degrees of hemolytic anemia, splenomegaly, and jaundice. The severity of the condition can range from asymptomatic to severe, transfusion-dependent anemia.

This code is appropriate for documenting a confirmed diagnosis of hereditary elliptocytosis. It should be used when medical record documentation clearly identifies the inherited nature of the elliptocytosis, often supported by family history, specific genetic testing results, or characteristic peripheral blood smear findings.

• Differentiate from acquired elliptocytosis, which would be coded differently.
• Consider additional codes for associated manifestations, such as hemolytic anemia (e.g., D58.9 for other specified hereditary hemolytic anemias if not further specified by elliptocytosis itself, or D55.0 for anemia due to enzyme defects if applicable).
• Ensure documentation specifies "hereditary" to support the use of this code.
