ICD-10 Code E61.4 – Chromium deficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E61.4 – Chromium deficiency
What it is
E61.4 identifies chromium deficiency, a documented lack of chromium in the body. Use it when the record supports a nutritional deficiency diagnosis, not merely low intake or a nonspecific diet concern.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe possible impaired glucose tolerance, weight loss, peripheral neuropathy, or other signs of poor nutritional status, but these are not specific to chromium deficiency alone.
When to use this code
Use E61.4 when the clinician documents chromium deficiency as a diagnosis or clearly links symptoms to that deficiency. It may apply in malnutrition, prolonged inadequate intake, or other situations where chromium depletion is specifically identified. If the note only says “low chromium” without a diagnosis, check documentation.
Do not use for
Do not use this code for general malnutrition, vague dietary insufficiency, or abnormal laboratory results without a documented deficiency diagnosis. It is also not for diabetes or neuropathy unless the provider explicitly connects them to chromium deficiency.
Coding tip
Assign E61.4 only when the provider clearly documents chromium deficiency; otherwise, query the record for clarification.
