What This Code Means

A pervasive developmental disorder that does not fit the criteria for autism, Asperger's syndrome, Rett syndrome, or other childhood disintegrative disorder.

Coding Tips

• •Use this code only after ruling out more specific pervasive developmental disorder codes
• •Document the atypical features that prevent classification into other F84 categories

Clinical Significance

This code captures pervasive developmental disorders that are specifically identified but do not meet full criteria for autistic disorder, Asperger's syndrome, Rett syndrome, or childhood disintegrative disorder. This includes overactive disorder associated with intellectual disability and stereotyped movements. These conditions still represent significant neurodevelopmental challenges requiring specialized support.

Documentation Requirements

• ✓Provider documentation of a specific pervasive developmental disorder that does not fit other classified categories
• ✓Evidence of pervasive developmental features (social, communication, or behavioral) not meeting full criteria for F84.0, F84.2, F84.3, or F84.5
• ✓Documentation of functional impairment in social, communication, or adaptive domains
• ✓Assessment distinguishing this from other developmental or psychiatric conditions
• ✓Current treatment plan including developmental or behavioral interventions
