- Significant delayed gastric emptying as documented by standard scintigraphic imaging of solid food; and
- Individual is refractory to or intolerant of at least two (2) anti-emetic and prokinetic drug classes; and
- No mechanical obstruction is found on diagnostic testing; and
- Individual’s nutritional status is sufficiently low that ALL of the following criteria are met:
- Failure to meet adequate caloric needs despite adequate trials of dietary adjustment, oral supplements, or tube enteral nutrition and
- The individual must be in a stage of wasting as indicated by AT LEAST ONE of the following:

- Serum albumin is less than 3.4 grams; or
- Blood urea nitrogen (BUN) level is less than ten (10) mg; or
