ICD-10 Code E61.3 – Manganese deficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E61.3 – Manganese deficiency
What it is
E61.3 identifies manganese deficiency, a nutritional lack of this trace mineral. Use it when the record documents insufficient manganese intake or depletion.
Clinical signs
Clinical features vary; refer to documentation. Reported findings may include nonspecific nutritional deficiency signs, but you should code only when the provider clearly documents manganese deficiency.
When to use this code
Use E61.3 when the clinician diagnoses manganese deficiency, whether from poor intake, malabsorption, or another documented cause. Apply it only when the chart supports a true deficiency state, not merely a risk or dietary concern.
Do not use for
Do not use this code for general malnutrition, other vitamin or mineral deficiencies, or uncertain low intake without a documented deficiency. Check documentation if the record does not specify manganese.
Coding tip
Code E61.3 only when manganese deficiency is explicitly stated; otherwise, query for clarification.
