ICD-10 Code E44.0 – Moderate protein-calorie malnutrition (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E44.0 – Moderate protein-calorie malnutrition
What it is
This code identifies moderate protein-calorie malnutrition, a state of inadequate protein and calorie intake that leads to measurable nutritional deficiency. Use it when documentation clearly supports moderate malnutrition, not just poor appetite or weight loss.
Clinical signs
Typical findings may include reduced intake, weight loss, muscle wasting, or loss of subcutaneous fat. Clinical features vary; refer to documentation and avoid assuming severity without provider confirmation.
When to use this code
Use E44.0 when the provider documents moderate malnutrition or states nutritional deficiency of moderate severity. It is also appropriate when the record links malnutrition to chronic illness, poor intake, or inadequate absorption and the degree is clearly described. Check documentation if severity is unclear.
Do not use for
Do not use this code for unspecified malnutrition, mild malnutrition, or severe malnutrition. Also avoid it when the chart only mentions weight loss, cachexia, or poor nutrition without a documented diagnosis.
Coding tip
Code only the documented severity; if the note does not specify moderate malnutrition, query the provider.
