ICD-10 Code F94.9 – Childhood disorder of social functioning, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F94.9 – Childhood disorder of social functioning, unspecified
What it is
This code identifies an unspecified childhood disorder affecting social functioning. Use it when the record describes a social development or interaction problem, but does not name a more specific disorder.
Clinical signs
Clinical features vary; refer to documentation. Records may note impaired peer relationships, unusual social behavior, or difficulty adapting in social settings, but the diagnosis is not further defined.
When to use this code
Use F94.9 when the clinician documents a childhood social functioning disorder without specifying the exact type. It is appropriate when the chart supports a social or developmental concern, but details are incomplete or nonspecific.
Choose this code only after reviewing the note for a more specific F94 diagnosis. If the provider later identifies a defined condition, update the code to match that documentation.
Do not use for
Do not use this code when the record clearly identifies a specific childhood social disorder or another mental health diagnosis. Check documentation if the issue is better explained by a different condition.
Coding tip
Before assigning F94.9, look for a more specific diagnosis in the assessment, impression, or problem list.
