ICD-10 Code F50.020 – Anorexia nervosa, binge eating/purging type, mild (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.020 – Anorexia nervosa, binge eating/purging type, mild
What it is
This code identifies a mild form of anorexia nervosa in which the patient restricts intake and also has binge-eating or purging behavior. Use it when the documentation clearly states this subtype and severity.
Clinical signs
Typical features include distorted body image, fear of weight gain, restrictive eating, and episodes of binge eating or compensatory purging. Clinical features vary; refer to documentation.
When to use this code
Use F50.020 when the record specifically documents anorexia nervosa, binge eating/purging type, and mild severity. It may appear in psychiatric, primary care, or inpatient notes when the diagnosis is established and clearly supported. Check documentation if severity or subtype is not stated.
Do not use for
Do not use this code for anorexia without nervosa, other eating disorders, or anorexia nervosa of a different severity level. Do not assume bingeing or purging unless it is documented.
Coding tip
Match both the subtype and severity exactly as documented before assigning F50.020.
