Inherited from F40 (Phobic anxiety disorders)

F40 codes phobic anxiety disorders — including agoraphobia (F40.0x), social phobia (F40.1x), and specific phobias (F40.2x). Specific phobia subtypes are coded by trigger category: animal, natural environment, blood-injection-injury, situational, and other. Document the feared stimulus, avoidance behavior, and degree of impairment to support the most specific code.

Code details

Code attributes

  • Non-billable/Non-specific code

Coding rules

  • Specify the leaf code — the parent code (e.g. F32) is a navigational header; billing requires a leaf code (F32.0, F32.1, etc.) that matches the documented presentation.
  • Document onset, course, and severity (mild / moderate / severe) plus functional impact. Payers use this combination when adjudicating medical necessity.
  • Attach a validated instrument score (PHQ-9, GAD-7, PCL-5, or equivalent) at intake and at follow-up where applicable. Objective measures support code selection and continued authorization.
  • Review at every visit and update if presentation changes — including remission and partial remission states.
