Parenteral (PEN) and Enteral (EN) Nutrition Support in the Home
Intestinal failure-associated liver disease, ICD-10 K76.83, was added to the covered diagnosis codes effective 10/01/2026. Parenteral nutrition in the home is medically necessary for inanition from conditions such as Crohn's disease, obstruction, short bowel syndrome and malabsorption when the patient can receive no more than 30% of caloric needs orally or cannot benefit from enteral feedings. Enteral feeding is not medically necessary if 25% of estimated daily calories or less are being administered, except when transitioning off total parenteral nutrition.
