BillableOther autoimmune hemolytic anemia
HCC Category Mapping
What This Code Means
A condition where the immune system attacks and destroys red blood cells, causing anemia. This is a type of autoimmune hemolytic anemia not classified elsewhere.
Coding Tips
Clinical Significance
Other autoimmune hemolytic anemia encompasses autoimmune-mediated red blood cell destruction that does not fit neatly into the drug-induced, warm, cold, or mixed categories. This may include paroxysmal cold hemoglobinuria (Donath-Landsteiner hemolytic anemia), which involves a biphasic immunoglobulin G antibody that binds red blood cells at cold temperatures and causes complement-mediated lysis upon rewarming. It also captures rare autoimmune hemolytic anemia variants with unusual antibody characteristics or atypical laboratory patterns.
Documentation Requirements
- ✓Document the specific type of autoimmune hemolytic anemia when known (for example, paroxysmal cold hemoglobinuria).
- ✓Include direct antiglobulin test results with antibody characterization showing the condition does not fit warm, cold, or mixed categories.
- ✓Record hemoglobin levels, hemolysis markers, and any specialized testing such as the Donath-Landsteiner test.
- ✓Document any underlying triggers or associated conditions and the treatment approach.
