Overactivity

This code describes a state of excessive or heightened activity, often characterized by restlessness, impulsivity, and difficulty sustaining attention. It represents a general symptom of overactivity that is not further specified or attributed to a more definitive psychiatric or neurological disorder.

Use this code when documentation indicates a patient exhibits overactivity without a more specific diagnosis such as Attention-Deficit/Hyperactivity Disorder (ADHD) or hyperkinetic syndrome. This is appropriate when the provider notes "overactivity" as a presenting symptom or finding, and no further diagnostic clarity is provided.

• Do not use this code if a more specific diagnosis, such as ADHD (F90.x), is documented.
• Consider querying the provider for further specificity if the overactivity is persistent or significantly impacts daily functioning.
• This code should generally be sequenced as a secondary diagnosis, unless the overactivity is the primary reason for the encounter and no underlying cause has been identified.
