Other specified hereditary hemolytic anemias

This code signifies a group of inherited disorders characterized by premature destruction of red blood cells due to intrinsic defects not classified elsewhere. These conditions result from genetic mutations affecting red blood cell membrane proteins, enzymes, or hemoglobin structure, leading to chronic or episodic hemolysis.

Use this code for hereditary hemolytic anemias such as hereditary spherocytosis, hereditary elliptocytosis, G6PD deficiency, pyruvate kinase deficiency, and other rare red blood cell enzyme defects. Documentation should clearly state the specific type of hereditary hemolytic anemia and confirm its genetic origin, often supported by laboratory findings like abnormal red blood cell morphology or enzyme assays.

• Do not use for thalassemia or sickle cell anemia, which have their own specific codes.
• Ensure the documentation specifies "hereditary" or "congenital" to differentiate from acquired hemolytic anemias.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting care.
