Deficiency of other vitamins

This code signifies a deficiency of a vitamin other than those specifically classified elsewhere (e.g., Vitamin A, C, D, B1, B2, B6, B12, K, or niacin). It indicates a nutritional inadequacy of a less common or unspecified vitamin, leading to potential metabolic or physiological dysfunction.

Use this code when documentation specifies a deficiency of a vitamin not covered by more specific ICD-9-CM codes, such as pantothenic acid, biotin, or choline deficiency. It is appropriate when laboratory tests confirm low levels of an "other" vitamin or when clinical signs and symptoms are attributed to such a deficiency.

• Avoid using this code if a more specific vitamin deficiency code is available and documented.
• Ensure documentation clearly states the specific "other" vitamin deficient, if known, or justifies the use of an unspecified code.
• Consider sequencing this code after any underlying conditions causing the deficiency, if applicable.
