ICD-10 Code E61.0 – Copper deficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E61.0 – Copper deficiency
What it is
Copper deficiency is a lack of copper in the body that can impair normal blood formation, nerve function, and other metabolic processes. Use this code when the record clearly documents copper deficiency.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include anemia, neutropenia, and neurologic symptoms such as numbness, gait problems, or weakness.
When to use this code
Use E61.0 when the provider diagnoses copper deficiency or documents it as a current condition being evaluated or treated. It may also apply when deficiency is confirmed in the chart as due to poor intake, malabsorption, or another documented cause. You should code the condition only when the documentation supports it.
Do not use for
Do not use this code for suspected deficiency without confirmation in the record. Check documentation if the note describes general malnutrition, anemia, or neurologic symptoms without stating copper deficiency.
Coding tip
Query the provider if the chart shows compatible findings but does not clearly name copper deficiency.
