ICD-11 and Adult Undernutrition: What Dietitians Need to Know

In this episode, we’re breaking down the upcoming transition to ICD-11 and what it means for documenting and diagnosing adult malnutrition, soon to be termed undernutrition, beginning in 2027.Developed by the World Health Organization, ICD codes shape how conditions are defined, documented, and reimbursed worldwide. With ICD-11, adult undernutrition will align with the Global Leadership Initiative on Malnutrition (GLIM) framework, meaning clinicians and organizations need to start preparing now, including EMR updates in 2026.Joining us is Stacy Pelekhaty from the R Adams Cowley Shock Trauma Center at the University of Maryland Medical Center. We discuss what’s changing, documentation and reimbursement implications, practical preparation steps, and how this shift strengthens the value of nutrition care.Learn more at dnsdpg.org.
