How long must bowel rest be required for Medicare coverage of HPN?

• A. 90 days
• B. 30 days
• C. 180 days
• D. 7 days

Answer: (A)

Medicare coverage for home parenteral nutrition hinges on establishing irreversible intestinal failure by requiring bowel rest for a defined period. The required duration is ninety days. This period shows that the GI tract cannot meet the patient’s nutritional needs despite rest and that dependence on parenteral nutrition is long-term rather than temporary. It helps ensure that coverage is reserved for chronic cases rather than short-term or reversible conditions. If, after this interval, the patient still cannot maintain nutrition enterally and remains dependent on PN for weight and health, coverage is justified. Shorter or longer intervals outside this standard do not meet the criterion.
