Other thalassemias

This code signifies a group of inherited blood disorders characterized by abnormal hemoglobin production, specifically thalassemias that do not fit into more specific categories like alpha or beta thalassemia major/intermedia. These conditions result in varying degrees of anemia due to reduced synthesis of one or more globin chains.

Apply this code when documentation specifies a type of thalassemia that is not otherwise classified, such as delta-beta thalassemia, epsilon-gamma-delta-beta thalassemia, or other rare forms. It is appropriate when genetic testing or hematological studies confirm a thalassemia diagnosis that doesn't fall under D56.0, D56.1, or D56.2.

• Carefully review documentation to ensure the specific type of thalassemia is not more precisely coded elsewhere (e.g., D56.0 for Alpha thalassemia, D56.1 for Beta thalassemia).
• Be mindful of the Excludes1 notes; never code this alongside hemoglobin C disease, hemoglobin E disease, other hemoglobinopathies, or any sickle-cell related diagnoses.
• Ensure the medical record clearly identifies the thalassemia as "other" or specifies a rare variant not covered by more specific codes.
