Code Description

ICD-10 F50.02 is a billable code used to indicate a diagnosis of anorexia nervosa, binge eating/purging type.

Key Diagnostic Point:

Anorexia nervosa, binge eating/purging type is a severe eating disorder characterized by an intense fear of gaining weight and a distorted body image, leading to self-imposed starvation and excessive weight loss. Individuals with this subtype engage in recurrent episodes of binge eating, followed by inappropriate compensatory behaviors such as self-induced vomiting, misuse of laxatives, diuretics, or enemas, or excessive exercise. This disorder can lead to significant physical health complications, including electrolyte imbalances, cardiovascular issues, and gastrointestinal problems, as well as psychological effects such as anxiety, depression, and social withdrawal. Diagnosis is based on clinical criteria, including the frequency of binge eating and purging behaviors, as well as the individual's weight status and psychological assessment. Treatment typically involves a multidisciplinary approach, including nutritional rehabilitation, psychotherapy, and medical management to address both the physical and psychological aspects of the disorder.
