This code is utilized when the healthcare provider has determined that the anemia is related to a lack of Vitamin B12, yet further details about the deficiency are not available or documented.

1. Pallor and Fatigue: The patient presents with noticeable pallor and reports persistent fatigue, which are common symptoms associated with anemia.

2. Neurological Symptoms: The patient exhibits neurological symptoms such as numbness or tingling in the hands and feet, which can be indicative of vitamin B12 deficiency.

7. Dietary History: The patient's dietary history shows insufficient intake of vitamin B12-rich foods, which could contribute to the deficiency.
