Which coding system classifies stroke as a neurological disorder?

The coding system that classifies stroke as a neurological disorder is ICD-11. This system, developed by the World Health Organization (WHO), provides a more comprehensive and updated framework for classifying diseases and health conditions, including neurological disorders such as stroke.

ICD-11 incorporates advances in medical knowledge and practice, allowing for a more nuanced understanding of health conditions, including the nature and types of strokes. The inclusion of strokes in the neurological disorders section signifies the recognition of their complex nature and the necessity for precise coding to facilitate effective healthcare management, research, and billing processes.

In contrast, ICD-9 and ICD-10 are earlier versions of the International Classification of Diseases, which have limitations in categorizing and describing the full spectrum of neurological disorders compared to ICD-11. DSM-5, on the other hand, is specifically used for diagnosing and classifying mental health disorders, making it unrelated to the classification of neurological disorders like stroke.
