ICD-10 Code F40.01 – Agoraphobia with panic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F40.01 – Agoraphobia with panic disorder
What it is
F40.01 identifies agoraphobia occurring with panic disorder. Use it when fear of situations such as crowds, open spaces, or public transport is linked to panic attacks and avoidance.
Clinical signs
Common findings include intense fear or anxiety in specific settings, panic attacks, and avoidance of places where escape may feel difficult. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents both agoraphobia and panic disorder, or panic attacks occurring in the context of agoraphobic avoidance. You should confirm the provider links the two conditions. If the note only says panic attacks or only agoraphobia, check documentation.
Do not use for
Do not use F40.01 for panic disorder without agoraphobia, or for fear-based avoidance that is not documented as agoraphobia. Do not assume the diagnosis from anxiety symptoms alone.
Coding tip
Assign F40.01 only when the provider documents the combined diagnosis; otherwise query for clarification.
