Other hemoglobinopathies

This code represents a group of inherited disorders affecting hemoglobin structure or production that are not specifically classified elsewhere. These conditions result in abnormal red blood cells and can lead to varying degrees of anemia and other systemic complications. Examples include unstable hemoglobin variants or methemoglobinemia.

Use this code when documentation indicates a diagnosed hemoglobinopathy that doesn't fit a more specific ICD-9-CM code, such as sickle cell disease or thalassemia. This code is appropriate for conditions like hemoglobin H disease, hereditary methemoglobinemia, or other rare hemoglobin variants. Supporting documentation should clearly state the specific type of hemoglobinopathy if known, and confirm it's not one with a dedicated code.

• Always strive for the most specific hemoglobinopathy code available before resorting to this "other" category.
• Ensure the physician's documentation explicitly states a diagnosis of "other hemoglobinopathy" or a specific variant not otherwise classified.
• Do not use this code for sickle cell disorders (282.4-282.6) or thalassemias (282.4, 282.8).
