ICD-10 Code D59.19 – Other autoimmune hemolytic anemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D59.19 – Other autoimmune hemolytic anemia
What it is
D59.19 identifies autoimmune hemolytic anemia that does not fit a more specific ICD-10 category. Use it when the record shows immune-mediated red blood cell destruction, but the subtype is not otherwise specified.
Clinical signs
Typical findings include anemia with evidence of hemolysis, such as jaundice, fatigue, or dark urine. Clinical features vary; refer to documentation for the exact autoimmune pattern and supporting workup.
When to use this code
Use this code when the clinician documents autoimmune hemolytic anemia and does not specify warm, cold, or another defined subtype. It may also fit when the note describes immune hemolysis but leaves the exact type unclear. Check documentation if the record supports a more specific code.
Do not use for
Do not use D59.19 for non-autoimmune hemolytic anemia or for autoimmune hemolysis with a clearly documented, more specific ICD-10 code. Do not guess the subtype from limited chart details.
Coding tip
Query for the specific autoimmune subtype whenever the documentation only says “hemolytic anemia.”
