Which description best defines eligibility for Medicare Part B home enteral nutrition benefit?

• A. A patient with permanent non-function or disease of structures that normally permit food to reach the small bowel, or a small bowel disease that impairs digestion/absorption, requiring tube feeding to maintain weight and strength; condition could be anatomic or motility disorder.
• B. A patient with temporary anorexia seeking weight gain
• C. A pediatric patient with a common cold
• D. A patient who only drinks water

Answer: (A)

Medicare Part B home enteral nutrition coverage hinges on a clear medical necessity: the patient cannot meet nutritional needs through normal oral intake because of permanent GI tract impairment or a small bowel disease that impairs digestion or absorption, making tube feeding at home necessary to maintain weight and strength. The condition can be an anatomical problem or a motility disorder, but the key is that the impairment is ongoing and requires home enteral feeding to sustain nutrition. This distinguishes it from situations like temporary loss of appetite or minor illnesses, where enteral support at home is not indicated. It also excludes scenarios where a person simply drinks water or has a non-nutrition-related condition like a common cold in a pediatric patient.
