E64.9

What This Code Means

This code describes long-term health problems that result from a past nutritional deficiency when the specific type of deficiency is not documented or known. It's used when a patient has lasting effects from malnutrition but the exact cause cannot be identified.

Coding Tips

• •Use this code only when the specific nutritional deficiency (such as vitamin deficiency, protein deficiency, or mineral deficiency) cannot be determined; if the type is known, use the more specific sequelae code instead
• •Ensure documentation clearly indicates these are late effects or sequelae of a previous nutritional problem rather than an active current deficiency
