Stereotypic movement disorder

This code represents a mental disorder characterized by repetitive, nonfunctional motor behavior that interferes with normal activities. These movements, such as head banging, body rocking, or self-biting, are often rhythmic and appear purposeless. The diagnosis requires that these behaviors cause significant distress or impairment in social, occupational, or other important areas of functioning.

Use this code when documentation clearly indicates a diagnosis of stereotypic movement disorder, often observed in individuals with developmental disabilities or intellectual impairment. It applies when the repetitive movements are not due to a general medical condition, substance use, or another mental disorder like tics or obsessive-compulsive disorder. Supporting documentation should detail the specific movements, their frequency, duration, and the resulting functional impairment.

• Differentiate from tics (e.g., Tourette's syndrome) which are typically sudden, rapid, recurrent, nonrhythmic motor movements or vocalizations.
• Ensure documentation specifies that the movements are not better explained by another mental or neurological disorder.
• Consider co-occurring intellectual disabilities or pervasive developmental disorders, which may require additional coding.
