ICD-10 Code F50.019 – Anorexia nervosa, restricting type, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.019 – Anorexia nervosa, restricting type, unspecified
What it is
Use this code for anorexia nervosa when the restricting type is documented, but the record does not specify the exact severity or other qualifying detail. It identifies a restrictive eating disorder with significant weight and body-image concerns.
Clinical signs
Typical findings include restricted food intake, fear of weight gain, and disturbance in body image or recognition of low weight. Clinical features vary; refer to documentation.
When to use this code
Assign this code when the clinician documents anorexia nervosa, restricting type, and does not provide a more specific subtype or detail needed for a different code. Use it for outpatient, inpatient, or problem-list documentation that clearly supports the diagnosis.
If the note only says “anorexia” without confirming anorexia nervosa, check documentation before coding. Also verify that binge-eating/purging behavior is not documented, because that would point to another subtype.
Do not use for
Do not use for simple poor appetite, weight loss alone, or unspecified eating concerns without a documented diagnosis of anorexia nervosa. Do not use if another anorexia nervosa subtype is documented.
Coding tip
Code the most specific anorexia nervosa subtype documented and query if the record does not clearly support restricting type.
