Attention-deficit hyperactivity disorder, unspecified type

This code represents a neurodevelopmental disorder characterized by persistent patterns of inattention and/or hyperactivity-impulsivity that interfere with functioning or development. It is used when the specific presentation (predominantly inattentive, hyperactive-impulsive, or combined type) has not been documented or determined.

Use this code when ADHD is diagnosed, but the clinician has not specified the subtype. This often occurs during initial evaluations or when documentation is incomplete regarding the predominant symptoms. It is supported by a physician's diagnosis of ADHD without further specification.

• Avoid using this code if the documentation clearly specifies a subtype of ADHD (e.g., predominantly inattentive type).
• Query the provider for clarification on the specific ADHD subtype if possible to allow for more precise coding.
• Do not use this code for symptoms of inattention or hyperactivity that do not meet the diagnostic criteria for ADHD.
