ICD-10 Code F40.02 – Agoraphobia without panic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F40.02 – Agoraphobia without panic disorder
What it is
F40.02 identifies agoraphobia when the fear of being in places or situations is not accompanied by panic disorder. It refers to avoidance driven by anxiety about escape, help, or safety.
Clinical signs
Patients may avoid crowds, public transport, open spaces, or being outside alone. Clinical features vary; refer to documentation for the specific fear pattern, avoidance behavior, and whether panic attacks are absent.
When to use this code
Use this code when the record clearly documents agoraphobia without panic disorder. It fits cases where the clinician describes situational avoidance or marked anxiety in public settings, but does not diagnose panic disorder. If panic symptoms are present, check documentation before coding.
Do not use for
Do not use F40.02 if the chart documents panic disorder, panic attacks as the primary diagnosis, or another phobic disorder instead. Check documentation when the diagnosis is unclear or mixed.
Coding tip
Assign F40.02 only when the provider explicitly separates agoraphobia from panic disorder in the assessment.
