When to use F44.9

Use this group for phobias, panic, generalized anxiety, OCD, PTSD, acute and adjustment disorders, and dissociative and somatic symptom disorders. Match the code to the specific syndrome and document the precipitating trigger where relevant. For F44.9 specifically, dissociative symptoms where the specific subtype is not documented.

Documentation & billing
