ICD-10 Code E61.9 – Deficiency of nutrient element, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E61.9 – Deficiency of nutrient element, unspecified
What it is
E61.9 is used when the record documents a deficiency of a nutrient element, but the specific nutrient is not identified. It indicates a nutritional deficiency diagnosis without further detail.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect a general nutrient deficiency, such as poor intake, weight loss, or related symptoms, but the exact presentation depends on the missing element.
When to use this code
Use this code when the clinician documents a nutrient element deficiency and does not name the specific substance, or when the chart is too nonspecific to assign a more precise code. It is appropriate only after reviewing available notes, problem lists, and test results. If the nutrient is identified, code that specific deficiency instead.
Do not use for
Do not use E61.9 when the deficiency is clearly specified, such as iron or vitamin deficiency. Do not use it for malnutrition or other nutritional disorders unless the documentation supports this code.
Coding tip
If the record says only “nutrient deficiency,” confirm whether a specific element is named before assigning E61.9.
