ICD10 code of Autism and ICD9 code

Autism is a neurodevelopmental disorder characterized by difficulties in social interaction, communication, and restricted and repetitive patterns of behavior. In the International Classification of Diseases, 10th Revision (ICD-10), autism is classified under the category of "Pervasive developmental disorders" with the code F84.0.

ICD-10 is a coding system used by healthcare professionals to classify and code various diseases and disorders for diagnostic and billing purposes. The code F84.0 specifically represents "Childhood autism" in the ICD-10 system. It is important to note that the ICD-10 code for autism is used globally and provides a standardized way of identifying and documenting this disorder.

In contrast, the International Classification of Diseases, 9th Revision (ICD-9), which was the previous version of the coding system, also included codes for autism. In ICD-9, autism was classified under the category of "Infantile autism" with the code 299.0. However, since the implementation of ICD-10, healthcare providers have transitioned to using the newer coding system.

The use of standardized codes like ICD-10's F84.0 enables healthcare professionals to accurately identify and track the prevalence of autism, ensuring consistency in diagnosis and treatment. These codes also facilitate communication between healthcare providers, researchers, and insurers, leading to better understanding and management of autism spectrum disorders.
