Unspecified vitamin A deficiency

This code represents a general lack of sufficient vitamin A in the body, without further specification of the particular manifestation or cause. It indicates a nutritional deficiency that can impact vision, immune function, and epithelial tissue health.

Use this code when documentation indicates a diagnosis of vitamin A deficiency but lacks details regarding specific clinical signs, symptoms, or the underlying etiology. This is appropriate when laboratory tests confirm low vitamin A levels without further clinical elaboration.

• Avoid using this code if more specific manifestations of vitamin A deficiency (e.g., xerophthalmia, night blindness) are documented.
• Always query for more specific documentation if available, as this is an "unspecified" code.
• Consider sequencing this code as a secondary diagnosis if the primary reason for the encounter is a related condition or symptom.
