ICD-10 Code F84.8 – Other pervasive developmental disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F84.8 – Other pervasive developmental disorders
What it is
Use this code for pervasive developmental disorders that do not fit a more specific ICD-10 diagnosis. It covers developmental conditions with persistent social, communication, or behavioral differences when the record does not support a narrower code.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include early developmental concerns, impaired social interaction, communication differences, and restricted or repetitive behaviors.
When to use this code
Use F84.8 when the provider documents a pervasive developmental disorder but does not name autism spectrum disorder, Asperger syndrome, or another more specific condition. It is also appropriate when the chart describes atypical pervasive developmental features and the exact subtype is unclear.
Do not use for
Do not use this code if documentation supports a more specific pervasive developmental disorder code. Check documentation and avoid using F84.8 for unrelated developmental, language, or intellectual disorders.
Coding tip
Query the provider when the diagnosis is vague, because a more specific code may be available.
