Anemia of prematurity

This code identifies a normocytic, normochromic anemia that commonly develops in premature infants, typically between 3 and 12 weeks of age. It is primarily caused by a blunted erythropoietin response to anemia, a shortened red blood cell lifespan, and rapid growth.

Assign this code for premature infants diagnosed with anemia where no other specific cause (e.g., hemorrhage, hemolysis, nutritional deficiency) is identified. Documentation should confirm prematurity and the presence of anemia, often supported by hemoglobin and hematocrit levels.

• Do not use this code for anemia due to acute blood loss or other specified causes in a premature infant; code the specific anemia.
• Consider sequencing this code after codes for prematurity or low birth weight, if applicable.
• Ensure the medical record clearly distinguishes this from other types of neonatal anemia.
