ICD-10 Code E61 – Deficiency of other nutrient elements (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E61 – Deficiency of other nutrient elements
What it is
E61 identifies a deficiency of nutrient elements other than the major vitamins and minerals covered elsewhere. Use it when documentation shows a specific nutrient lack, but the record does not support a more precise code.
Clinical signs
Clinical features vary; refer to documentation. Findings may include signs of poor intake, weight loss, fatigue, or other manifestations linked to the identified nutrient deficiency.
When to use this code
Use E61 when the clinician documents a deficiency of an unspecified or other nutrient element and no more specific ICD-10-CM code applies. It is appropriate for confirmed nutritional deficiency diagnoses, follow-up of a known deficiency, or evaluation after abnormal assessment findings. Check documentation for the exact nutrient involved.
Do not use for
Do not use this code for general malnutrition, dehydration, or vitamin-specific deficiencies that have their own codes. If the chart names a different disorder or lacks support for deficiency, check documentation.
Coding tip
Capture the exact nutrient named in the record whenever possible, because a more specific code may be available.
