Anxiety ICD-10 Codes: F41.1 GAD, F41.0 Panic, F40.10 Social Anxiety (FY2027)
Anxiety codes live in two ICD-10-CM categories: F41 for generalized and panic-type anxiety, and F40 for phobic anxiety, which includes social anxiety and agoraphobia. The most common mistake is staying on F41.9 after the assessment has named the disorder.
Short answer
The ICD-10-CM code for generalized anxiety disorder is F41.1. Panic disorder is F41.0, social anxiety disorder is F40.10 (Social phobia, unspecified), agoraphobia is F40.00 to F40.02, and F41.9 is anxiety disorder, unspecified. F41.8 and F41.3 cover other specified and mixed anxiety disorders.
Anxiety disorder codes
| Code | ICD-10-CM title |
|---|---|
| F41.1 | Generalized anxiety disorder |
| F41.0 | Panic disorder [episodic paroxysmal anxiety] |
| F41.3 | Other mixed anxiety disorders |
| F41.8 | Other specified anxiety disorders |
| F41.9 | Anxiety disorder, unspecified (unspecified) |
| F40.10 | Social phobia, unspecified |
| F40.11 | Social phobia, generalized |
| F40.00 | Agoraphobia, unspecified (unspecified) |
| F40.01 | Agoraphobia with panic disorder |
| F40.02 | Agoraphobia without panic disorder |
| F40.8 | Other phobic anxiety disorders |
| F40.9 | Phobic anxiety disorder, unspecified (unspecified) |
F40.10 is "unspecified" in its ICD-10-CM title but is the code DSM-5-TR uses for social anxiety disorder.
Choosing between them
- F41.1 when the assessment documents generalized anxiety disorder.
- F41.0 for panic disorder. If agoraphobia is also present, F40.01 (Agoraphobia with panic disorder) captures both.
- F40.10 for social anxiety disorder; F40.11 when it's documented as generalized.
- F41.8 for an anxiety disorder that's specified in the record but has no code of its own.
- F41.9 only until the assessment supports something more specific.
Billing notes
- Unspecified codes are a placeholder. F32.9, F32.A, F33.9, F41.9, and F43.20 are valid, but many payers and Medicaid programs flag them on ongoing treatment. Use them at intake if needed, then update once the assessment supports a specific code.
- Code to the highest specificity the record supports. Severity, episode, and remission status belong in the code when the note documents them.
- The diagnosis must support the service. A code that doesn't fit the CPT code tends to deny as CO-11. See behavioral health denial codes.
- Z codes rarely work as the primary diagnosis. Codes like Z63.0 (Problems in relationship with spouse or partner) describe circumstances, and many plans won't pay psychotherapy with one listed first.
