Beneficiary meets the test of permanence when the treating practitioner documents the impairment is of long and indefinite duration (permanence satisfied even if improvement is possible in the future).
Enteral nutrition is indicated when medical records show full or partial non-function or disease of the structures that normally permit food to reach the small bowel.
Enteral nutrition is indicated when medical records show disease that impairs digestion and/or absorption of an oral diet directly or indirectly by the small bowel.
