Specific Coding for Pervasive developmental disordersOverview

Non-specific codes like F84 require more characters. Use one of these billable codes instead:

  • Use F84.0 for Autistic disorder

  • Use F84.2 for Rett's syndrome

  • Use F84.3 for Other childhood disintegrative disorder

  • Use F84.5 for Asperger's syndrome
