ICD-10 Code E61.8 – Deficiency of other specified nutrient elements (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E61.8 – Deficiency of other specified nutrient elements
What it is
E61.8 identifies a documented deficiency of a nutrient element that is not classified elsewhere. Use it when the record names a specific nutrient shortage, but no more precise ICD-10 code applies.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect the missing nutrient and can include nonspecific signs of poor intake, malabsorption, or deficiency-related symptoms.
When to use this code
Use E61.8 when the provider clearly documents a deficiency of a specific nutrient element and the chart supports that diagnosis. It is appropriate when the condition is not captured by a more specific deficiency code. If the record is vague or incomplete, check documentation before assigning the code.
Do not use for
Do not use this code for general malnutrition, dehydration, or vitamin deficiencies that have their own ICD-10 codes. If the nutrient deficiency is unspecified, check documentation and code the closest supported diagnosis.
Coding tip
Code the named nutrient deficiency only when the documentation supports it and no more specific ICD-10 option is available.
