University of Wisconsin Hospitals and Clinics Authority Incorrectly Billed Medicare Inpatient Claims With Severe Malnutrition

Nutritional Marasmus and other/unspecified severe protein-calorie malnutrition are two types of severe malnutrition listed in the International Classification of Diseases, Clinical Modification. Previous OIG reviews have determined that hospitals incorrectly billed for Kwashiorkor, a third type of severe malnutrition. Nutritional Marasmus and other/unspecified severe protein-calorie malnutrition are each classified as a type of major complication or comorbidity (MCC). Adding MCCs to a Medicare claim can result in a higher Medicare payment.
