ICD-10 Code F84 – Pervasive developmental disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F84 – Pervasive developmental disorders
What it is
F84 covers pervasive developmental disorders, a group of neurodevelopmental conditions that affect social communication and behavior. Use it when the record documents a pervasive developmental disorder without a more specific ICD-10-CM diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings include delayed or atypical social interaction, communication differences, and restricted or repetitive behaviors.
When to use this code
Use F84 when the clinician documents a pervasive developmental disorder and does not specify a narrower subtype. It may also fit when the chart uses the broader term and no more detailed diagnosis is recorded. Check documentation if the note suggests autism spectrum disorder or another specific condition.
Do not use for
Do not use F84 when the provider documents a specific autism spectrum diagnosis or another defined developmental disorder. If the record is unclear, check documentation rather than assuming the broader code.
Coding tip
Code the most specific documented diagnosis first; use F84 only when the record supports the broader category.
