Code Description

ICD-10 E63 is a billable code used to indicate a diagnosis of other nutritional deficiencies.

Key Diagnostic Point:

E63 encompasses a variety of nutritional deficiencies that do not fall under more specific categories. These deficiencies can arise from inadequate dietary intake, malabsorption syndromes, or increased metabolic demands. Common nutritional deficiencies include those of vitamins, minerals, and other essential nutrients that can lead to significant health issues. Long-term effects of malnutrition can manifest as growth retardation in children, weakened immune function, muscle wasting, and increased susceptibility to chronic diseases. Sequelae of nutritional deficiencies may include anemia, osteoporosis, and neurological disorders, depending on the specific nutrients lacking. Clinicians must assess dietary habits, medical history, and physical examination findings to diagnose and manage these deficiencies effectively. Treatment often involves dietary modifications, supplementation, and addressing underlying causes of malnutrition.
