ICD-10 Code E64.8 – Sequelae of other nutritional deficiencies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E64.8 – Sequelae of other nutritional deficiencies
What it is
E64.8 identifies lasting effects that remain after a nutritional deficiency has been treated or is no longer active. Use it when the current record describes residual problems from a prior deficiency, not the deficiency itself.
Clinical signs
Clinical features vary; refer to documentation. You may see persistent weakness, neurologic changes, skin or mucosal findings, or other residual impairment linked to a past deficiency.
When to use this code
Use E64.8 when the clinician documents sequelae, residuals, or late effects from a nutritional deficiency and the original deficiency is no longer the active reason for care. It is appropriate when the note clearly ties the current condition to a prior deficiency. Check documentation if the record only says “history of deficiency” without ongoing effects.
Do not use for
Do not use this code for an active nutritional deficiency, suspected deficiency, or nonspecific malnutrition. If the chart does not describe residual effects, choose the current condition or ask for clarification.
Coding tip
Link the residual condition to the prior deficiency in the documentation before assigning E64.8.
