Other autoimmune hemolytic anemia

This code represents a form of hemolytic anemia where the body's immune system mistakenly attacks and destroys its own red blood cells, and the specific type of autoimmune hemolytic anemia (AIHA) is not further specified or falls outside of the more common classifications. This condition leads to a reduction in red blood cell count, resulting in symptoms such as fatigue, pallor, and jaundice.

Use this code when documentation clearly indicates autoimmune hemolytic anemia, but the specific subtype (e.g., warm, cold, drug-induced) is not identified or does not fit a more precise code. This code is appropriate when the physician's diagnosis is "other autoimmune hemolytic anemia" or "AIHA, type unspecified." Supporting documentation includes laboratory findings confirming hemolysis and positive direct antiglobulin test (DAT) or other immune markers, without further subtyping.

• Do not use this code if a more specific type of autoimmune hemolytic anemia (e.g., warm, cold, drug-induced) is documented; instead, select the appropriate subcategory.
• Ensure documentation explicitly states "autoimmune" as the cause of the hemolytic anemia to differentiate from other forms of hemolytic anemia.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter or hospitalization, or as a secondary diagnosis if it is a comorbidity affecting patient care.
