Hemoglobin E-beta thalassemia

This code represents a genetic blood disorder characterized by a compound heterozygosity for hemoglobin E and beta thalassemia. Individuals inherit one gene for beta thalassemia and one gene for hemoglobin E, leading to varying degrees of anemia and other hematological complications. The severity can range from mild to severe, mimicking thalassemia intermedia or major.

Apply this code when documentation explicitly states a diagnosis of "Hemoglobin E-beta thalassemia." This diagnosis is typically confirmed through hemoglobin electrophoresis and genetic testing. Use this code for patients presenting with microcytic hypochromic anemia, splenomegaly, or other symptoms consistent with this specific hemoglobinopathy.

• Do not confuse this with other types of beta thalassemia (e.g., D56.1, D56.3) or hemoglobin E disease (D58.2), as these are distinct conditions.
• Ensure the documentation clearly specifies "Hemoglobin E-beta thalassemia" and not just "beta thalassemia" or "hemoglobin E."
• Review "Excludes1" notes carefully to avoid incorrect co-coding with related but mutually exclusive conditions.
