ICD-10 Code F40.29 – Other specified phobia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F40.29 – Other specified phobia
What it is
F40.29 identifies a phobic anxiety disorder tied to a specific fear that does not fit a more common named phobia. Use it when the documented phobia is clearly described but not otherwise classified.
Clinical signs
Typical findings include marked fear or anxiety about a specific object or situation, with avoidance or distress that is out of proportion. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents a specific phobia that is not listed elsewhere in ICD-10-CM. It is appropriate when the record names the feared trigger and supports a phobic disorder diagnosis. If the documentation is vague, check documentation before coding.
Do not use for
Do not use F40.29 for generalized anxiety, panic disorder, or a named phobia that has its own code. If the chart does not confirm a phobic disorder, check documentation.
Coding tip
Code the most specific documented phobia term and avoid defaulting to F40.29 when a more specific ICD-10-CM option applies.
