Pervasive developmental disorder, unspecified

This code represents a broad category for developmental disorders characterized by severe and pervasive impairment in several areas of development, including reciprocal social interaction, communication skills, or the presence of stereotyped behaviors, interests, and activities. It signifies a significant delay or qualitative abnormality in these areas, without further specification of the particular pervasive developmental disorder.

This code is appropriate when documentation indicates a pervasive developmental disorder but lacks the specific diagnostic criteria to assign a more precise code, such as autism spectrum disorder or Rett syndrome. It should be used when the clinician has diagnosed a pervasive developmental disorder but has not yet differentiated the specific type.

• Avoid using this code if more specific documentation is available; always strive for the highest level of specificity.
• Query the provider for further clarification if the medical record suggests a more defined pervasive developmental disorder.
• This code is often a placeholder and should ideally be replaced with a more specific diagnosis once further evaluation is completed.
