Other specified anemias

This code signifies anemias that are clearly defined but do not fit into more specific categories of anemia. It encompasses various less common or atypical forms of anemia where the underlying cause or mechanism is known and documented, but a dedicated ICD-9-CM code does not exist.

Use this code when documentation specifies an anemia that is not iron deficiency, pernicious, aplastic, hemolytic, or due to chronic disease, but rather a distinct, identified type. Examples include sideroblastic anemia, congenital dyserythropoietic anemia, or anemia due to enzyme deficiencies not otherwise classified. Supporting documentation must clearly state the specific type of anemia.

• Avoid using this code as a default for "anemia NOS"; ensure the documentation specifies a particular type.
• Always review documentation for more specific anemia codes (e.g., 280.x, 282.x, 283.x, 285.2x) before assigning this code.
• If the specific type of anemia is unknown or unspecified, use 285.9 (Anemia, unspecified).
