ICD-10 Code F50.022 – Anorexia nervosa, binge eating/purging type, severe (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.022 – Anorexia nervosa, binge eating/purging type, severe
What it is
F50.022 identifies severe anorexia nervosa with binge eating and/or purging behavior. Use it when documentation shows this subtype and severity level.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include restrictive intake, episodes of binge eating, and compensatory purging behaviors such as vomiting or misuse of laxatives.
When to use this code
Use this code when the provider clearly documents anorexia nervosa, binge eating/purging type, and specifies severe. It is appropriate for assessments, problem lists, and encounters focused on this eating disorder. If severity or subtype is not stated, check documentation.
Do not use for
Do not use it for anorexia nervosa without binge eating/purging features, or when the record only says “anorexia” as a symptom. Check documentation if the diagnosis is bulimia nervosa or another eating disorder.
Coding tip
Code the documented subtype and severity exactly as stated; if either is missing, query the provider.
