Unspecified vitamin B deficiency

This code signifies a general lack of one or more B vitamins without specific identification of which particular B vitamin is deficient. It indicates a nutritional deficiency impacting various metabolic processes, potentially leading to symptoms like fatigue, neurological issues, or dermatological changes.

Use this code when documentation indicates a vitamin B deficiency but does not specify the exact type (e.g., B1, B2, B6, B12, folate). This is appropriate when laboratory tests confirm a B vitamin deficiency, but further specificity is unavailable or not yet determined.

• Avoid using this code if a more specific vitamin B deficiency (e.g., B12 deficiency, folate deficiency) is documented; always code to the highest level of specificity.
• Consider sequencing this code after a code for the underlying cause of the deficiency, if known (e.g., malabsorption syndromes).
• Review documentation for any associated symptoms or conditions that may also require separate coding.
