ICD-10 Code F50.012 – Anorexia nervosa, restricting type, severe (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.012 – Anorexia nervosa, restricting type, severe
What it is
F50.012 identifies anorexia nervosa with a restricting pattern and severe clinical severity. Use it when the record documents severe restriction of food intake, not binge-eating or purging behavior.
Clinical signs
Typical findings include intense fear of weight gain, persistent restriction of intake, and marked disturbance in body image. Clinical features vary; refer to documentation for severity and whether the restricting subtype is confirmed.
When to use this code
Use this code when the provider clearly documents anorexia nervosa, restricting type, and severe severity. It is appropriate in outpatient, inpatient, or behavioral health records when the diagnosis is established and supported by the note.
Choose this code when the chart distinguishes the restricting subtype from binge-eating/purging presentations. If severity is not stated, or the subtype is unclear, check documentation before assigning F50.012.
Do not use for
Do not use this code for unspecified anorexia nervosa, other eating disorders, or cases where restriction is not documented. Check documentation if the record describes weight loss without a confirmed eating disorder diagnosis.
Coding tip
Verify both the subtype and severity in the provider’s assessment before coding F50.012.
