Under Medicare guidelines, which documentation is required for HPN coverage when a malnourished patient has a partial small bowel obstruction and limited oral intake?

• A. The physician must write an order for nil per os
• B. A radiology report documenting obstruction
• C. Medical record must document failure of an enteral feeding trial, or explain why an feeding tube is not an option
• D. No further documentation is necessary

Answer: (C)

Medicare coverage for home parenteral nutrition hinges on showing that the gut-based route cannot meet the patient’s nutritional needs. In a malnourished patient with a partial small bowel obstruction and limited oral intake, the chart must demonstrate one of two things: an enteral feeding trial was attempted and failed, or there is a clear explanation why enteral feeding is not feasible. This means documenting that an enteral nutrition trial was actually tried with appropriate monitoring and it did not meet needs (for example, the patient could not tolerate the feeds, showed intolerance or complications, or the obstruction prevented adequate enteral intake). Alternatively, the record should directly justify why placing and using a feeding tube isn’t possible or safe given the obstruction (for instance, anatomical or clinical contraindication). Such documentation shows that parenteral nutrition is medically necessary because enteral/oral nutrition cannot supply adequate nutrition. Simply noting the obstruction or relying on imaging alone does not confirm that an enteral feeding trial was attempted or that feeding via the gut is contraindicated. Nor does it meet the requirement that “no further documentation” is necessary.
