ICD-10 Code F50.02 – Anorexia nervosa, binge eating/purging type (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.02 – Anorexia nervosa, binge eating/purging type
What it is
F50.02 identifies anorexia nervosa with binge eating and/or purging behaviors. Use it when the record documents restrictive eating plus episodes of bingeing, vomiting, laxative use, or other purging.
Clinical signs
Typical findings include markedly restricted intake, intense fear of weight gain, distorted body image, and recurrent binge-purge behavior. Clinical features vary; refer to documentation.
When to use this code
Use F50.02 when the clinician clearly documents anorexia nervosa, binge eating/purging type, or equivalent wording. It also applies when the note describes anorexia nervosa with purging behaviors, even if bingeing is not separately detailed.
Code from the provider’s diagnosis, assessment, or discharge summary, not from suspected eating disorder symptoms alone. If the record does not specify the subtype, check documentation.
Do not use for
Do not use this code for bulimia nervosa, unspecified eating disorder, or anorexia nervosa without binge eating or purging. Check documentation when the subtype is unclear.
Coding tip
Look for explicit mention of bingeing or purging in the provider note before assigning F50.02.
