How VA rates this — Rating Formula for Eating Disorders
These percentages summarize the regulatory criteria already mapped to this diagnostic code. They do not predict a Veteran's individual evaluation or establish service connection.
Self-induced weight loss to less than 80 percent of expected minimum weight, with incapacitating episodes of at least six weeks total duration per year, and requiring hospitalization more than twice a year for parenteral nutrition or tube feeding.
Self-induced weight loss to less than 85 percent of expected minimum weight with incapacitating episodes of six or more weeks total duration per year.
Self-induced weight loss to less than 85 percent of expected minimum weight with incapacitating episodes of more than two but less than six weeks total duration per year.
Binge eating followed by self-induced vomiting or other measures to prevent weight gain, or resistance to weight gain even when below expected minimum weight, with diagnosis of an eating disorder and incapacitating episodes of up to two weeks total duration per year.
Binge eating followed by self-induced vomiting or other measures to prevent weight gain, or resistance to weight gain even when below expected minimum weight, with diagnosis of an eating disorder but without incapacitating episodes.

Evidence information
When reviewing the criteria, useful evidence categories can include diagnosis and treatment records, objective testing identified by the schedule, documented frequency/duration/severity when the criteria use those concepts, and functional effects described in medical or lay evidence. The relevant evidence depends on the actual claim and medical facts.
VMC does not diagnose conditions, guarantee a percentage, or advise anyone to exaggerate symptoms.
