The National Center for Health Statistics (NCHS), the Federal agency responsible for use of the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10) in the United States, [ has developed a clinical modification of the classification for morbidity purposes. The ICD-10 is used to code and classify mortality data from death certificates, having
replaced ICD-9 for this purpose as of January 1, 1999. ICD-10-CM is planned as the replacement for ICD-9-CM, volumes 1 and 2.

WHO has authorized the development of an adaptation of ICD-10 for use in the United States for U.S. government purposes. As agreed, all modifications to the ICD-10 must conform to WHO conventions for the ICD. ICD-10-CM was developed following a thorough evaluation by a Technical Advisory Panel and extensive additional consultation with physician groups, clinical coders, and others to assure clinical accuracy and utility.
The entire draft of the Tabular List of ICD-10-CM, and the preliminary crosswalk between ICD-9-CM and ICD-10-CM were made available on the NCHS website for public comment. The public comment period ran from December 1997 through February 1998. The American Hospital Association and the American Health Information Management Association conducted a field test for ICD-10-CM in the summer of 2003, with a subsequent report Adobe PDF file [PDF - 1.8 MB]External Web Site Icon. All comments and suggestions from the open comment period and the field test were reviewed, and additional modifications to ICD-10-CM were made based on these comments and suggestions.
