Iron deficiency

This code represents a state of insufficient iron stores in the body without the presence of anemia. It indicates a depletion of iron reserves necessary for various physiological functions, often preceding the development of iron deficiency anemia.

Use this code when laboratory tests confirm low ferritin levels or other markers of iron depletion, but hemoglobin and hematocrit remain within normal limits. Documentation should clearly state "iron deficiency" without mention of anemia.

• Do not use this code if the patient also has iron deficiency anemia; instead, report the appropriate D50.- code.
• Ensure documentation explicitly differentiates between iron deficiency and iron deficiency anemia to avoid miscoding.
• This code may be sequenced as a primary or secondary diagnosis depending on the reason for the encounter and the patient's overall clinical picture.
