F84.0 diagnosis code: autistic disorder

ICD-10-CM code F84.0 refers to Autistic Disorder, a subtype of Autism Spectrum Disorder (ASD). It is characterized by persistent deficits in social communication and social interaction, along with restricted and repetitive behavior patterns. These symptoms typically present in early childhood and cause clinically significant impairment in social, occupational, or other important areas of functioning.

Is F84.0 billable?

F84.0 is a billable ICD-10 code that healthcare professionals can use for insurance claims and reimbursement purposes. Accurate coding is essential for proper documentation and treatment planning for patients diagnosed with autistic disorder.

Clinical information

  • F84.0 describes a developmental disorder that begins in early childhood, often before the age of three.
  • It involves significant challenges in social interaction, communication, and the presence of repetitive behaviors or restricted interests.
  • Autistic disorder is classified under mental disorders in both the ICD-10-CM and the diagnostic and statistical manual of mental disorders (DSM-5). It's under the category of specific developmental disorders, given its early onset and distinct impact on social and communication skills.
  • Children diagnosed under this code may exhibit social communication impairments, such as avoiding eye contact, delayed language skills, or difficulty responding to social cues.
  • Repetitive actions like arranging objects, repeating phrases, or engaging in specific routines are common features.
  • The condition varies widely depending on the child’s developmental stage, cognitive level, and chronological age.
  • It falls under the autism spectrum disorder (ASD) umbrella, a group of pervasive developmental disorders that also includes Asperger's syndrome, childhood disintegrative disorder, and childhood autism.
  • The underlying cause of autism remains unknown, though it's thought to involve genetic and environmental factors.
  • While there is no cure, early intervention programs, including behavioral therapies, speech-language therapy, and occupational therapy, can significantly improve outcomes.
  • Qualified healthcare professionals or mental health professionals use a standardized diagnostic process and criteria from sources like the DSM-5 and ICD-10-CM to confirm the diagnosis.
  • Lifelong support and appropriate treatment can help individuals develop skills and navigate daily life more effectively.
