History • In theearly 17th century, John Graunt began the statistical study of health and diseases. • Later, in 1837, William Farr thought of getting a unique classification for causes of diseases. • The Bertillon Classification of Causes of Death was developed by Jacques Bertillon in 1893 which then was implemented in 1898. • In 1938, the name was then changed to International Classification of Diseases (ICD). • The 9th edition of this was brought into implementation in 1978

- 5. Format of ICD-9-CM •The codes are broken into 3 digit categories. The first three digits determine the category. • The fourth digit specifies the sub category. • The Fifth digit is used for sub classification and specifies the type of treatment or diagnosis required.
- 6. Methods to FindICD-9-CM Codes • Good research habits are necessary. • 5 basic steps to identify the correct code. - Correct identification of main term or condition. - Use the index to locate the problem. - Review information with all instructions. - Select the correct code from tabular list. - Use correct sequence while mentioning multiple codes.
- 7. ICD-10-CM Preview • Anew version of codes was implemented by WHO in 1992. The National Center for Health Statistics (NCHS) stated that this version was not detailed enough to be used at a national level. • Soon the advanced version ICD-10-CM will be brought into practice from October 1, 2014. This is a more detailed coding system that contains a codes that are more specific.
