ICD Code F90.9

ICD code F90.9 is used to identify a diagnosis of attention-deficit hyperactivity disorder (ADHD) when the specific type is not specified. This code is applied when a patient exhibits symptoms of ADHD, such as inattention, hyperactivity, and impulsivity, but the healthcare provider has not determined or documented whether it is predominantly inattentive, predominantly hyperactive-impulsive, or combined type. This code helps in the classification and billing processes within the healthcare revenue cycle, ensuring that services related to the diagnosis are accurately recorded and reimbursed.

1. Inattention Symptoms: - Frequently makes careless mistakes in schoolwork, work, or other activities. - Often has difficulty sustaining attention in tasks or play activities. - Does not seem to listen when spoken to directly. - Fails to follow through on instructions and fails to finish schoolwork, chores, or duties in the workplace. - Has difficulty organizing tasks and activities. - Avoids, dislikes, or is reluctant to engage in tasks that require sustained mental effort. - Often loses things necessary for tasks or activities. - Easily distracted by extraneous stimuli. - Forgetful in daily activities.

2. Hyperactivity Symptoms: - Often fidgets with or taps hands or feet, or squirms in seat. - Leaves seat in situations when remaining seated is expected. - Runs about or climbs in situations where it is inappropriate. - Unable to play or engage in leisure activities quietly. - Often "on the go," acting as if "driven by a motor." - Talks excessively.

3. Impulsivity Symptoms: - Blurts out answers before a question has been completed. - Has difficulty waiting for their turn. - Interrupts or intrudes on others (e.g., butts into conversations or games).

4. Duration and Impact: - Symptoms must be present for at least six months. - Symptoms must be inconsistent with developmental level. - Symptoms must negatively impact social, academic, or occupational functioning.

5. Exclusion of Other Conditions: - Symptoms are not better explained by another mental disorder (e.g., mood disorder, anxiety disorder, dissociative disorder, or a personality disorder). - Symptoms do not occur exclusively during the course of schizophrenia or another psychotic disorder.

6. Age of Onset: - Several inattentive or hyperactive-impulsive symptoms were present before age 12 years.

7. Settings: - Symptoms are present in two or more settings (e.g., at home, school, or work; with friends or relatives; in other activities).
