ICD-10 Code F50.023 – Anorexia nervosa, binge eating/purging type, extreme (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.023 – Anorexia nervosa, binge eating/purging type, extreme
What it is
F50.023 identifies anorexia nervosa with both binge eating and purging behaviors, documented as extreme severity. Use it when the record clearly states this specific subtype and severity.
Clinical signs
Typical documentation may note restrictive eating, intense fear of weight gain, distorted body image, plus binge eating and compensatory purging. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents anorexia nervosa, binge/purge type, and specifically describes the condition as extreme. It may appear in behavioral health, nutrition, or inpatient records. Check documentation if severity or subtype is unclear.
Do not use for
Do not use this code for anorexia nervosa without binge/purge behavior, or when the chart does not specify extreme severity. Do not assign it if documentation only says “eating disorder”; check documentation.
Coding tip
Code only when both subtype and severity are explicitly documented; otherwise query the provider for clarification.
