What is ICD-9
ICD – International Classification of Diseases. 9 – Ninth Revision. This classification was developed by World Health Organization. In this classification for each known disease assigned unique code number. Majority of the U.S. healthcare systems use the ICD-9 codes for making diagnosis and settling payments. The coding is standard around the world, however, in the 2010’s many countries went on to use ICD-10 and then ICD – 11 systems, which include more information.
