Deficiency of other specified B group vitamins

This code represents a nutritional deficiency involving B vitamins other than folate (B9) or cobalamin (B12). It encompasses deficiencies of B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), or B7 (biotin) when specifically documented. These deficiencies can lead to a variety of systemic symptoms affecting neurological, dermatological, and gastrointestinal systems.

Use this code when medical record documentation clearly indicates a deficiency of a specific B-group vitamin other than folate or B12. This often follows laboratory confirmation of low vitamin levels or a clinical diagnosis based on characteristic symptoms and response to supplementation. Examples include thiamine deficiency (beriberi), niacin deficiency (pellagra), or pyridoxine deficiency.

• Ensure the documentation specifies which "other" B vitamin is deficient; otherwise, consider using unspecified deficiency codes if no specific B vitamin is identified.
• Remember the Excludes1 note: never code this alongside D51.- (B12 deficiency anemia) or D52.- (folate deficiency anemia).
• Code any associated manifestations or complications of the vitamin deficiency, such as neuropathy or dermatitis, in addition to the deficiency code.
