ICD-10 Code F40.10 – Social phobia, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F40.10 – Social phobia, unspecified
What it is
F40.10 identifies social phobia, also called social anxiety disorder, when the record does not specify the type or severity. Use it for fear or avoidance of social situations that causes distress or functional impairment.
Clinical signs
Clinical features include marked fear of embarrassment, scrutiny, or negative judgment in social or performance settings. You may see avoidance, intense anxiety, or distress that is out of proportion to the situation; check documentation.
When to use this code
Use F40.10 when the clinician documents social phobia or social anxiety disorder without further specification. It also fits when the note describes social fear and avoidance but does not identify a specific subtype. If the chart names a more specific anxiety disorder, code that instead.
Do not use for
Do not use this code for generalized anxiety, panic disorder, or simple shyness without a documented disorder. If the provider documents another phobic disorder or a more specific social anxiety diagnosis, choose the more precise code.
Coding tip
Confirm the exact wording in the assessment; unspecified codes are appropriate only when documentation lacks a more specific diagnosis.
