ICD-10 Code F50.24 – Bulimia nervosa, extreme (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.24 – Bulimia nervosa, extreme
What it is
F50.24 identifies bulimia nervosa, extreme, a severe eating disorder marked by recurrent binge-eating episodes with compensatory behaviors. Use it when the documentation specifically states the extreme form.
Clinical signs
Typical findings include recurrent binge eating, self-induced vomiting, laxative or diuretic misuse, fasting, or excessive exercise. Clinical features vary; refer to documentation for the severity and associated behaviors.
When to use this code
Use F50.24 when the provider documents bulimia nervosa and specifies “extreme” or an equivalent severe presentation. It is appropriate when the record clearly supports this severity level and no more specific code is documented. Check documentation if the chart only says bulimia nervosa without severity.
Do not use for
Do not use this code for anorexia nervosa, binge-eating disorder, or unspecified eating disorder. Avoid it when bulimia is documented without the extreme qualifier.
Coding tip
Code the highest documented specificity, and query the provider if “extreme” is unclear or unsupported.
