Coding for Malnutrition in the Hospital: Does It Change Reimbursement?

Protein calorie malnutrition (PCM) is prevalent in the acute care setting, affecting up to 50% of hospitalized patients. PCM is associated with poor outcomes, including increased hospital and intensive care unit length of stay, hospital readmission rates, incidence of pressure injuries and nosocomial infections, and mortality. PCM is a financial burden on the healthcare system through direct costs related to treatment as well as indirect costs related to poorer outcomes and complications. Medical coding for malnutrition after a patient's hospital stay is poorly representative of the actual prevalence of malnutrition, as only a small percentage of these hospital stays are coded for PCM. Improvements in identification and coding of malnutrition can result in significant increases in hospital reimbursement, which can in part help defray increased costs associated with the condition.
