Attn-defct hyperactivity disorder, predom inattentive type

This diagnosis code signifies a neurodevelopmental disorder characterized by persistent difficulties with attention, organization, and executive function, without significant hyperactivity or impulsivity. Individuals primarily exhibit symptoms such as inattention to detail, difficulty sustaining attention, poor listening skills, and forgetfulness in daily activities. These symptoms must be present in multiple settings and interfere with social, academic, or occupational functioning.

Apply this code when documentation clearly indicates a diagnosis of Attention-Deficit Hyperactivity Disorder where the predominant presentation is inattention. Supporting documentation should include a comprehensive clinical evaluation, often involving psychological testing, confirming the diagnostic criteria for ADHD, predominantly inattentive presentation, as outlined in the DSM-5.

• Ensure the documentation explicitly states "predominantly inattentive type" or provides sufficient detail to rule out combined or hyperactive/impulsive presentations.
• Do not use this code if hyperactivity or impulsivity are significant features; consider F90.1 (predominantly hyperactive-impulsive type) or F90.2 (combined type).
• Code any co-occurring mental health conditions, such as anxiety or depression, separately.
