“ICD-10” is the abbreviated term used to refer to the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) and the International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS).
• ICD-10-CM 
is the diagnosis code set and is the updated version of ICD-9-CM Volumes 1 and 2.
• ICD-10-PCS is the code set of inpatient procedure codes and is the updated version of ICD-9-CM Volume 3.
The history of the International Classification of Diseases (ICD) extends back to the late 19th century, when the need for standardizing classification concepts and terminology was recognized by the medical community in Europe. Since 1900, the ICD for mortality has been modified about once every ten years, except for the 20-year interval between the ICD-9 and ICD-10.
Implementing revised Health Insurance Portability and Accountability Act of 1996 (HIPAA) standards and ICD-10 codes could potentially have the largest operational and technological impacts on the health care industry since Y2K. It’s also a significant undertaking for health insurance plans that requires extensive planning and execution.
The ICD-10 is copyrighted by the World Health Organization (WHO), which owns and publishes the classification. 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.
Implementation date
The compliance date for implementation of the ICD-10-CM/PCS is October 1, 2013.
The benefit of ICD-10
ICD-10-CM/PCS will:
• Enhance accurate payment for services rendered and facilitate evaluation of medical processes and outcomes
• Provide significant improvements through greater detailed information and the ability to expand in order to capture additional advancements in clinical medicine.
Comparing ICD-10 to ICD-9
Each successive revision has a similar core to the previous revision. However, ICD-10 differs from ICD-9 in the following respects:
• ICD-10 is far more detailed than ICD-9 with about 8,000 categories compared with 4,000 categories.
• ICD-10 transfers conditions among the classifications. For example, hemorrhage has been moved from the "circulatory" chapter to the "symptoms and signs" chapter.
• ICD-10 uses 4-digit alpha-numeric codes instead of the 4-digit numeric codes used in ICD-9.
• ICD-10 changes some coding rules. For example, the rules for coding "pneumonia and influenza," "maternal conditions," and "error and accidents in medical care" have been changed.
• ICD-10 provides new tabulation lists (e.g. the 113 causes list in the U.S. ICD-10 113 replaces the 72 causes list in the U.S. ICD-9).
Tabulation lists
The leading causes of death are determined using a specific tabulation list and rules for ranking. In ICD-10, the 113 causes list is used for ranking all deaths except infant deaths, which are ranked separately on a list of 130 causes. ICD-10 also provides a list of 39 selected causes of death, which is used to show mortality data for geographic areas, a list of 124 selected causes of fetal death, and a list of motor vehicle accident deaths.
