ICD-10 Code F50.22 – Bulimia nervosa, moderate (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.22 – Bulimia nervosa, moderate
What it is
F50.22 identifies bulimia nervosa when the disorder is documented as moderate. It is used for a diagnosed eating disorder marked by recurrent binge eating and compensatory behaviors, with severity specified by the clinician.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include recurrent binge episodes, inappropriate compensatory behaviors, and ongoing concern about weight or body shape.
When to use this code
Use F50.22 when the record clearly states bulimia nervosa and specifies moderate severity. Apply it for outpatient, inpatient, or behavioral health documentation that supports the diagnosis and severity level.
If the note only says bulimia nervosa without severity, check documentation before assigning this code. Do not infer moderate severity from symptoms alone.
Do not use for
Do not use this code for anorexia nervosa, binge-eating disorder, or unspecified eating disorder. Also avoid it when bulimia is documented without a severity level; check documentation.
Coding tip
Code the documented severity exactly as stated, and query the provider if “moderate” is unclear or missing.
