263.9
ICD-9-CMThis code represents a general form of malnutrition characterized by an inadequate intake or absorption of protein and calories, without further specification of the type or severity. It indicates a nutritional deficiency that is not clearly defined as marasmus, kwashiorkor, or other specific forms of protein-calorie malnutrition.
Use this code when documentation indicates a diagnosis of protein-calorie malnutrition but lacks details regarding the specific type (e.g., marasmus, kwashiorkor) or severity (e.g., mild, moderate, severe). This code is appropriate when the provider's assessment broadly identifies nutritional inadequacy without further clinical elaboration.
