    ICD-10-CM Code For Eating Disorders: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group F50 includes diagnoses such as anorexia nervosa, bulimia nervosa, binge-eating disorder, and other specified or unspecified eating disorders that affect feeding behavior and nutritional status. These ICD-10-CM diagnosis codes are used to document clinical presentations of disordered eating, nutritional deficiency or excess, and related medical or psychiatric complications, capturing severity and associated physiological disturbances. Accurate coding within the ICD-10-CM F50 group supports complete clinical documentation and appropriate reimbursement.

    Typical Clinical Scenarios

    • A teenage patient with marked intentional restriction of food intake for several months presents to primary care with severe weight loss, bradycardia, amenorrhea, and dizziness due to orthostatic hypotension. The clinician documents persistent restrictive eating behavior with BMI well below expected for age and physiological instability prompting outpatient treatment planning and medical monitoring; an eating disorder diagnosis from this group is assigned to capture the restrictive presentation and associated physiological disturbance. Typical codes: F50.01, F50.011.
    • An adult patient is brought to the emergency department after an episode of self-induced vomiting with syncope and laboratory findings of hypokalemia and metabolic alkalosis; history reveals recurrent binge eating followed by purging behaviors for years. The acute electrolyte disturbance and need for medical stabilization occur in the setting of a chronic bulimic-type eating disorder, so a code indicating bulimia nervosa with current episodes and physiological complications is assigned. Typical codes: F50.2, F50.22.
    • A young adult with obesity reports recurrent episodes of large-volume binge eating without compensatory behaviors, significant distress, and impairment in social and occupational functioning; treatment is sought in outpatient behavioral health for chronic overeating and weight-related comorbidity. A diagnosis from this group is used to document binge-eating disorder as the primary psychiatric condition contributing to care and to guide psychosocial intervention and monitoring. Typical codes: F50.81, F50.811.
