    ICD-10-CM Code For Attention-Deficit Hyperactivity Disorders: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group F90 includes attention-deficit hyperactivity disorders such as predominantly inattentive presentation, predominantly hyperactive-impulsive presentation, and combined presentation, covering neurodevelopmental conditions characterized by inattention, hyperactivity, and impulsivity. These ICD-10-CM diagnosis codes are used to document clinical encounters for assessment, treatment planning, and monitoring of symptom severity, comorbid behavioral or developmental conditions, and functional impairment. Accurate coding within the ICD-10-CM F90 group supports proper claim adjudication and complete clinical documentation and appropriate reimbursement.

    ICD-10-CM F90: Attention-Deficit Hyperactivity Disorders Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification code group F90 covers attention-deficit hyperactivity disorders that primarily affect neurodevelopment and behavior, including inattentive, hyperactive-impulsive, and combined presentations. These diagnoses target brain and behavioral functioning in children and adolescents, though they may persist into adulthood. Accurate coding matters for reimbursement because it supports clear clinical documentation and appropriate claim adjudication tied to behavioral health services.

    Typical Clinical Scenarios

    • A 9-year-old child is brought by parents to a pediatrician for a school history of pervasive inattention, failure to complete assignments, distractibility in class, and academic decline present for more than six months. Symptoms began in early childhood, are present across home and school settings, and impair academic performance; the clinician documents predominantly inattentive symptoms and assigns a code from this group for an ADHD presentation without significant hyperactive-impulsive behavior. Typical codes: F90.0, F90.9.
    • A 7-year-old boy is evaluated urgently after teachers report frequent hyperactivity, running about the classroom, interrupting lessons, and inability to remain seated leading to safety concerns and repeated disciplinary incidents. The immediate concern for disruptive, developmentally inappropriate hyperactive-impulsive behaviors causing functional impairment prompts assignment of a code reflecting predominantly hyperactive-impulsive ADHD. Typical codes: F90.1, F90.9.
    • A 14-year-old adolescent with a long-standing diagnosis of ADHD presents for routine follow-up complicated by comorbid oppositional behaviors and mood lability; medication adherence is inconsistent and academic and family functioning remain impaired. The visit documents a combined-type, chronic ADHD presentation with associated behavioral comorbidity and ongoing treatment planning, leading to assignment of a code indicating combined hyperactive and inattentive symptoms or unspecified type when specificity is limited. Typical codes: F90.2, F90.9.
