ICD-10 Code F50.89 – Other specified eating disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.89 – Other specified eating disorder
What it is
Use this code for an eating disorder that causes clinically significant distress or impairment but does not meet criteria for a more specific eating disorder diagnosis. It is used when the provider documents an atypical or other specified presentation.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see disordered eating behaviors, weight or shape concerns, or abnormal eating patterns that fall short of a named diagnosis.
When to use this code
Assign F50.89 when the clinician documents “other specified eating disorder” or a clearly named atypical eating disorder presentation. Use it when the record shows a real disorder, but the documented features do not fit anorexia nervosa, bulimia nervosa, or binge-eating disorder.
Check documentation if the note is vague, because the exact subtype matters for coding. You should code the condition only when the provider identifies it as an eating disorder diagnosis.
Do not use for
Do not use this code for obesity, dieting, or nonspecific poor appetite without an eating disorder diagnosis. Do not use it when a more specific eating disorder code is documented.
Coding tip
Look for the provider’s exact wording; if a specific atypical eating disorder is named, code F50.89 unless documentation supports a more specific code.
