Mineral deficiency, not elsewhere classified

This code signifies a nutritional deficiency involving essential minerals that is not specifically categorized elsewhere in ICD-9-CM. It encompasses a range of conditions where the body lacks adequate levels of vital inorganic substances required for normal physiological function, excluding those with more specific codes.

Use this code when documentation indicates a generalized or unspecified mineral deficiency, such as hypomagnesemia, hypophosphatemia, or hypocalcemia, without a more specific ICD-9-CM code available. Supporting documentation should clearly state a diagnosis of mineral deficiency and specify that it is not otherwise classified.

• Avoid using this code if a more specific ICD-9-CM code for a particular mineral deficiency (e.g., iron deficiency anemia, iodine deficiency) is available.
• Always review documentation for the specific mineral involved; if identified, search for a more precise code.
• Consider sequencing this code after a code for the underlying cause of the deficiency, if known and documented.
