Anemia due to disorders of nucleotide metabolism

This code represents a type of anemia resulting from inherited or acquired defects in the biochemical pathways responsible for synthesizing or breaking down purines and pyrimidines. These metabolic errors disrupt DNA and RNA synthesis, impairing erythropoiesis and leading to insufficient red blood cell production. Examples include orotic aciduria or deficiencies in enzymes like adenosine deaminase.

Use this code when documentation clearly links anemia to a diagnosed disorder of nucleotide metabolism, such as hereditary orotic aciduria, Lesch-Nyhan syndrome, or specific enzyme deficiencies affecting nucleotide synthesis. Supporting documentation should include laboratory findings confirming the metabolic disorder and evidence of associated anemia.

• Ensure the documentation explicitly states the anemia is due to a nucleotide metabolism disorder, not just co-occurring.
• Code the specific nucleotide metabolism disorder first, if known and applicable, followed by this code.
• Do not confuse with anemias due to other metabolic disorders (e.g., D55.0-D55.2) or nutritional deficiencies (D50-D53).
