ICD-10 Code E83.2 – Disorders of zinc metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.2 – Disorders of zinc metabolism
What it is
E83.2 identifies disorders involving abnormal zinc metabolism, including deficiency, excess, or impaired handling of zinc. Use it when the record documents a zinc metabolism disorder rather than a nonspecific nutritional problem.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include skin changes, hair loss, poor wound healing, taste changes, or growth concerns when zinc imbalance is clinically significant.
When to use this code
Use E83.2 when the provider diagnoses a disorder of zinc metabolism and the chart supports abnormal zinc handling or deficiency/excess tied to metabolism. It is appropriate for confirmed conditions, follow-up care, or evaluation of a documented zinc metabolism disorder.
Do not substitute this code for vague fatigue, dietary counseling, or a history of low zinc without a current diagnosis. If the note only says “abnormal zinc level,” check documentation for the actual disorder before coding.
Do not use for
Do not use E83.2 for general malnutrition, isolated anemia, or unspecified vitamin/mineral deficiency unless zinc metabolism is specifically diagnosed. Check documentation if the condition is better described elsewhere.
Coding tip
Code E83.2 only when the provider links the finding to a zinc metabolism disorder, not merely an abnormal lab result.
