Personal history of nutritional deficiency

This code signifies that a patient has a documented past history of a nutritional deficiency, such as iron deficiency anemia, vitamin D deficiency, or protein-calorie malnutrition, which has since resolved. It indicates that while the deficiency is no longer active, it remains relevant to the patient's overall health status and potential future risks.

Use this code when a patient presents for follow-up care, monitoring, or management of conditions that may be influenced by a previous nutritional deficiency. It is appropriate when the deficiency itself is no longer being actively treated but is part of the patient's medical history, for example, during pregnancy after a resolved iron deficiency.

• This code should only be used when the nutritional deficiency is no longer active.
• Always sequence this code as a secondary diagnosis, as it represents a historical condition.
• Do not use this code if the patient currently has an active nutritional deficiency; instead, code the specific active deficiency.
