The landscape of mental health diagnosis relies heavily on precise coding systems, and within the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), code F90.0 holds significant importance. This code specifically designates Attention-deficit hyperactivity disorder, predominantly inattentive type, a condition impacting numerous individuals seeking mental health care. Understanding F90.0 is crucial for healthcare professionals, coders, and anyone navigating the complexities of ADHD diagnosis and treatment.
Understanding ICD-10-CM Code F90.0
F90.0 is a billable and specific code within the ICD-10-CM system. This means it’s not only a diagnostic classification but also recognized for reimbursement purposes in healthcare billing. When a patient is diagnosed with attention-deficit hyperactivity disorder, predominantly inattentive type, using F90.0 ensures accurate medical records and facilitates the claims process. The F90.0 code, as part of the 2025 ICD-10-CM edition, became effective on October 1, 2024, and has remained consistent since its introduction in 2016, highlighting its established place in the diagnostic framework. It is important to note that this is the American ICD-10-CM version; international versions may have variations.
Key Features and Synonyms of F90.0
The code F90.0 is applicable when the presentation of ADHD is primarily inattentive. This presentation, also known as Attention-deficit/hyperactivity disorder, predominantly inattentive presentation, is characterized by difficulties with focus, organization, and sustained attention, without the hyperactivity and impulsivity seen in other ADHD types. Common synonyms for F90.0 further clarify its scope. These include “ADHD, inattentive,” “ADHD, predominantly inattentive presentation,” “Attention deficit disorder,” and “Attention deficit hyperactivity disorder, predominantly inattentive type.” These terms are used interchangeably to describe the same diagnostic entity captured by the F90.0 code.
F90.0 in the ICD-10-CM Context and History
Within the broader ICD-10-CM system, F90.0 is categorized under F90, which encompasses all “Attention-deficit hyperactivity disorders.” While F90.0 specifically addresses the inattentive type, other related codes within the F90 family include F90.1 for the predominantly hyperactive type and F90.2 for the combined type. This hierarchical structure allows for nuanced classification of ADHD presentations. Looking at the code history of F90.0, it has remained unchanged from 2016 to 2025. This stability indicates a consistent and enduring diagnostic category within mental health care coding practices. Understanding F90.0 and its place within the ICD-10-CM system is essential for accurate diagnosis, effective treatment planning, and proper healthcare administration in the realm of mental health.
