The F90.0 diagnosis code, as defined within the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), is a critical tool for healthcare professionals in the United States. Specifically, F90.0 is designated for Attention-Deficit Hyperactivity Disorder, Predominantly Inattentive Type. This code is essential for accurate medical billing, record-keeping, and statistical tracking of ADHD.
Within the landscape of mental health and neurodevelopmental disorders, ADHD is a common condition affecting both children and adults. The inattentive presentation, coded as F90.0, is characterized by difficulties with focus, organization, and following through on tasks. Individuals with this presentation may not exhibit hyperactivity or impulsivity, which distinguishes it from other types of ADHD. This specific ICD-10-CM code allows for precise categorization and understanding of the different ways ADHD manifests.
The F90.0 code became billable in the US healthcare system starting October 1, 2015, marking its inclusion in the non-draft ICD-10-CM. It has remained unchanged in subsequent annual updates through 2025, solidifying its role in diagnostic coding. Common synonyms or terms associated with F90.0 include “ADHD, inattentive,” “Attention Deficit Disorder,” and “Predominantly Inattentive Presentation of ADHD.” These terms are crucial for clinicians and coders to correctly identify and apply the F90.0 diagnosis.
Understanding the F90.0 diagnosis code is vital not only for accurate clinical documentation and insurance reimbursement but also for research and public health initiatives related to ADHD. By using this standardized code, healthcare systems can effectively track the prevalence, treatment patterns, and outcomes associated with Attention-Deficit Hyperactivity Disorder, predominantly inattentive type.
