What F84.0 covers
F84.0 is the code for autism spectrum disorder. The tabular also includes infantile autism and Kanner's syndrome here. Whether a patient meets the DSM-5-TR criteria is the clinician's call.
Pediatrics, developmental medicine, psychology and behavioral therapy practices use it. Its siblings are Rett's syndrome (F84.2), other childhood disintegrative disorder (F84.3), Asperger's syndrome (F84.5), other pervasive developmental disorders (F84.8) and the unspecified code F84.9.
Billing and coding notes
F84.0 has an excludes1 for Asperger's syndrome (F84.5), so the two are never reported together. Code what the clinician documented: autism spectrum disorder goes to F84.0.
The F84 category says to code also any associated medical condition and intellectual disability. ADHD (F90.-) can be coded with F84.0, since pervasive developmental disorders are an excludes2 under F90.
