Attention-deficit hyperactivity disorder, combined type

This code identifies a neurodevelopmental disorder characterized by persistent patterns of inattention and hyperactivity-impulsivity that are more severe and frequent than typically observed in individuals at a comparable level of development. Individuals with the combined type exhibit significant symptoms meeting criteria for both inattention and hyperactivity-impulsivity. These symptoms interfere with functioning or development across multiple settings.

Use this code when the patient's medical record clearly documents a diagnosis of Attention-Deficit Hyperactivity Disorder (ADHD) where both inattentive and hyperactive-impulsive symptom clusters are present and meet diagnostic criteria. This diagnosis is typically made by a psychiatrist, psychologist, or other qualified mental health professional based on clinical evaluation and standardized assessments.

• Ensure documentation specifies "combined type" to differentiate from predominantly inattentive or hyperactive-impulsive presentations.
• Do not code based solely on symptoms; a definitive diagnosis of ADHD, combined type, must be present.
• Consider co-occurring conditions, such as anxiety or learning disorders, and code them separately if documented.
