It defines medical necessity requirements, including specific clinical conditions that qualify for coverage, wasting criteria for PEN, and functional impairments for EN, while excluding supplemental nutrition and conventional food items.
Action Required

For EN - physician orders specifying nutrients and administration method, documentation of functional impairments, and confirmation formula provides >75% of daily calories when given orally.
