ICD-10 Code F40.298 – Other specified phobia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F40.298 – Other specified phobia
What it is
Use this code for a phobic anxiety disorder involving a specific fear that does not fit a more defined phobia category. The fear is persistent and out of proportion to the actual danger.
Clinical signs
Typical findings include marked fear or anxiety when exposed to the trigger, avoidance of the situation, and distress that interferes with daily activities. Clinical features vary; refer to documentation.
When to use this code
Use F40.298 when the record clearly identifies a specific phobia but does not support a more precise ICD-10 option. It may apply when the feared object or situation is named in the chart and the clinician documents a phobic disorder. Check documentation if the note only describes general anxiety.
Do not use for
Do not use this code for generalized anxiety, panic disorder, or a phobia that has a more specific ICD-10 code. Do not assign it when the documentation is too vague to confirm a phobic disorder.
Coding tip
Code the documented phobic trigger and verify that “other specified” is supported before selecting F40.298.
