2025 ICD-10-CM code F90.9

Attention-deficit hyperactivity disorder, unspecified type. This diagnosis is used when the provider doesn't specify the predominant symptoms (inattention, hyperactivity, or combined).

F90.9 should be used when the provider does not specify the predominant presentation of ADHD (primarily inattentive, primarily hyperactive-impulsive, or combined).

Medical necessity for F90.9 is established by documenting functional impairment related to inattention, hyperactivity, and impulsivity, impacting the individual's daily life and requiring medical intervention.

Clinicians diagnose ADHD based on medical history, clinical assessment, interviews with parents/teachers, and by referencing DSM criteria.They manage the condition with medication, therapy, skills training, and stress management techniques.

In simple words: Unspecified ADHD is a condition usually diagnosed in children, marked by inattention, hyperactivity, and impulsive behavior, which makes it hard for them to focus and behave appropriately in various settings. The specific type of ADHD isn't documented in this case.

Unspecified attention-deficit/hyperactivity disorder (ADHD) is characterized by hyperactivity, inattention, and impulsivity, negatively impacting home, school, and social life.It typically begins in early childhood and may persist into adulthood. Symptoms include difficulty paying attention, focusing, sticking with tasks, disorganization, talkativeness, easy distractibility, forgetfulness, impatience, fidgeting, interrupting conversations, and social intrusiveness.Diagnosis is based on medical history, clinical assessment, interviews with parents and teachers, and comparison with DSM criteria.Treatment involves medication (stimulants and non-stimulants for children, antidepressants for adults), behavioral therapy, family and group therapy, organizational and skills training, and stress management techniques.

Example 1: A 7-year-old child consistently struggles to focus in class, often interrupting, fidgeting, and failing to complete assignments. The physician diagnoses ADHD but does not specify the subtype., A 10-year-old is referred for evaluation due to difficulties at school and home.They exhibit inattention, hyperactivity, and impulsivity, leading to a diagnosis of unspecified ADHD., An adult reports lifelong challenges with focus, organization, and impulsivity.Following assessment, they receive a diagnosis of unspecified ADHD, as the clinician doesn't determine a specific subtype.

Documentation should include evidence of inattention, hyperactivity, and impulsivity, impacting various aspects of the patient's life.Details of the clinical assessment, interviews, and rationale for not specifying the ADHD subtype should be included.
