ICD-10 Code E64.0 – Sequelae of protein-calorie malnutrition (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E64.0 – Sequelae of protein-calorie malnutrition
What it is
E64.0 identifies lasting effects that remain after protein-calorie malnutrition has occurred. Use it when the current problem is a residual condition, not active undernutrition.
Clinical signs
Clinical features vary; refer to documentation. Sequelae may include persistent weakness, wasting, delayed recovery, or other residual findings after the malnutrition episode has resolved.
When to use this code
Use E64.0 when the record clearly states a late effect or sequela from prior protein-calorie malnutrition. It fits follow-up visits where the ongoing issue is attributed to past malnutrition. Do not use it for active malnutrition without sequela wording.
Do not use for
Do not use this code for current protein-calorie malnutrition or for nonspecific weight loss alone. Check documentation if the provider has not linked the residual condition to a prior malnutrition episode.
Coding tip
Look for explicit terms such as “sequela,” “late effect,” or “due to prior malnutrition” before assigning E64.0.
