ICD-10 Code E61.5 – Molybdenum deficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E61.5 – Molybdenum deficiency
What it is
E61.5 identifies a deficiency of molybdenum, a trace mineral needed for certain enzyme functions. Use it when the record documents confirmed or suspected molybdenum deficiency.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe it as uncommon, and signs may overlap with broader nutritional deficiency findings.
When to use this code
Use E61.5 when the provider specifically documents molybdenum deficiency as a diagnosis, problem, or reason for evaluation. It may also apply when deficiency is listed as active and clinically relevant in the chart. If the record only mentions poor nutrition without naming molybdenum, check documentation.
Do not use for
Do not use this code for general malnutrition, other trace element deficiencies, or abnormal lab results without a documented deficiency diagnosis. Check documentation if the chart is unclear.
Coding tip
Assign E61.5 only when molybdenum deficiency is explicitly documented; otherwise, query the provider.
