ICD-10 Code F50.010 – Anorexia nervosa, restricting type, mild (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.010 – Anorexia nervosa, restricting type, mild
What it is
This code identifies anorexia nervosa with a restricting pattern and mild severity. Use it when documentation states the patient limits food intake without regular bingeing or purging.
Clinical signs
Common findings include low body weight, fear of gaining weight, and distorted body image. Clinical features vary; refer to documentation for severity and specific eating behaviors.
When to use this code
Use F50.010 when the clinician documents anorexia nervosa, restricting type, mild, or equivalent wording. It fits cases where restriction is the primary behavior and the record supports mild severity. If the note does not specify type or severity, check documentation.
Do not use for
Do not use this code for anorexia nervosa with binge-eating/purging behavior or when severity is not documented. Do not assign it for weight loss alone without a confirmed eating disorder diagnosis.
Coding tip
Match the exact subtype and severity in the provider note before coding.
