ICD-10 Code E83.9 – Disorder of mineral metabolism, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.9 – Disorder of mineral metabolism, unspecified
What it is
E83.9 identifies a disorder affecting the body’s handling of minerals, but the specific mineral imbalance is not named in the record. Use it when documentation confirms a mineral metabolism problem and no more precise code is available.
Clinical signs
Clinical features vary; refer to documentation. Patients may have signs related to abnormal mineral balance, but the chart should support a mineral metabolism disorder rather than a general nutritional or electrolyte issue.
When to use this code
Use E83.9 when the provider documents a disorder of mineral metabolism without specifying the mineral involved or the exact type of disturbance. It is appropriate when the diagnosis is confirmed, but the record remains nonspecific. If later documentation identifies the cause or mineral, code to the more specific option.
Do not use for
Do not use this code for isolated electrolyte abnormalities, dehydration, or clearly documented endocrine or renal disorders that better explain the condition. Check documentation if the record names a specific mineral disorder.
Coding tip
Choose the most specific mineral metabolism code supported by the note; use E83.9 only when the provider leaves the disorder unspecified.
