Other specified metabolic disorders affecting how the body processes nutrients and produces energy, not classified in other categories.
Coding Tips
- •Use this code for documented metabolic disorders that don't fit into the more specific E88 subcategories
- •Always specify the exact metabolic disorder in the medical record to support the diagnosis and allow for future code specificity

This may include rare inborn errors of metabolism, metabolic syndrome (when not coded separately), histiocytosis syndromes, and other specified metabolic derangements requiring ongoing management.
Documentation Requirements

- ✓Clinical or laboratory evidence supporting the metabolic diagnosis
