ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD), a medical classification list by the World Health Organization (WHO). It codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases.
The code set allows more than 14,400 different codes and permits the tracking of many new diagnoses. The codes can be expanded to over 16,000 codes by using optional sub-classifications. The detail reported by ICD can be further increased, with a simplified multi-axial approach, by using codes meant to be reported in a separate data field.
The WHO provides detailed information about ICD online, and makes available a set of materials online, such as an ICD-10 online browser, ICD-10 Training, ICD-10 online training, ICD-10 online training support, and study guide materials for download.
The International version of ICD should not be confused with national Clinical Modifications of ICD that frequently include much more detail, and sometimes have separate sections for procedures. The US ICD-10 CM, for instance, has some 68,000 codes. The US also has ICD-10 PCS, a procedure code system not used by other countries that contains 76,000 codes.
Work on ICD-10 began in 1983 and was completed in 1992.
The following is a List of ICD-10 codes.
|I||A00–B99||Certain infectious and parasitic diseases|
|III||D50–D89||Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism|
|IV||E00–E90||Endocrine, nutritional and metabolic diseases|
|V||F00–F99||Mental and behavioural disorders|
|VI||G00–G99||Diseases of the nervous system|
|VII||H00–H59||Diseases of the eye and adnexa|
|VIII||H60–H95||Diseases of the ear and mastoid process|
|IX||I00–I99||Diseases of the circulatory system|
|X||J00–J99||Diseases of the respiratory system|
|XI||K00–K93||Diseases of the digestive system|
|XII||L00–L99||Diseases of the skin and subcutaneous tissue|
|XIII||M00–M99||Diseases of the musculoskeletal system and connective tissue|
|XIV||N00–N99||Diseases of the genitourinary system|
|XV||O00–O99||Pregnancy, childbirth and the puerperium|
|XVI||P00–P96||Certain conditions originating in the perinatal period|
|XVII||Q00–Q99||Congenital malformations, deformations and chromosomal abnormalities|

National adoption for clinical use 
Some 25 countries use ICD-10 for reimbursement and resource allocation in their health system. A few of them made modifications to ICD to better accommodate this use of ICD-10. The article below makes reference to some of these modifications. The unchanged international version of ICD-10 is used in about 110 countries ICD-10 for cause of death reporting and statistics.
South Africa 
1 January 2005 Pretoria, Johannesburg, Cape town
1 July 1998 Victoria, New South Wales, Australian Capital Territory and Northern Territory implemented ICD-10-AM.
1 July 1999 Queensland, South Australia, Tasmania and Western Australia implemented ICD-10-AM.
France introduced a clinical addendum to ICD-10 in 2005. See also website of the ATIH.
Germany: ICD-10-GM (German Modification)
A Korean modification has existed since 2008.
The current Swedish translation of ICD-10 was created in 1997. A clinical modification has added more detail and omits codes of the international version in the context of clinical use of ICD:
The codes F64.1 (Dual-role transvestism), F64.2 (Gender identity disorder of childhood), F65.0 (Fetishism), F65.1 (Fetishistic transvestism), F65.5 (Sadomasochism), F65.6 (Multiple disorders of sexual preference) are not used in Sweden since 1 January 2009 according to a decision by the present Director General of The National Board of Health and Welfare, Sweden. The code O60.0 is not used in Sweden. Since 1 January 2009 the Swedish extension codes to O47 are recommended for use, instead of O60.0.
A Thai modifications exists since 2007.
Now Ministry of Public Health have **ICD 10 TM**
United States 
The deadline for the United States to begin using Clinical Modification ICD-10-CM for diagnosis coding and Procedure Coding System ICD-10-PCS for inpatient hospital procedure coding is currently October 1, 2014. The deadline was previously October 1, 2013. All HIPAA "covered entities" must make the change; a pre-requisite to ICD-10 is the adoption of EDI Version 5010 by January 1, 2012. Enforcement of 5010 transition by CMS, however, was postponed by CMS until March 31, 2012, with the federal agency citing numerous factors, including slow software upgrades. The implementation of ICD-10 has been subject to previous delays. In January 2009, the date was pushed back by two years, to October 1, 2013 rather than a prior proposal of October 1, 2011.
Even though the deadline for ICD-10 has been pushed back repeatedly, CMS recommends that medical practices take several years to prepare for implementation of the new code set. The basic structure of the ICD-10 code is the following: Characters 1-3 (the category of disease); 4 (etiology of disease); 5 (body part affected), 6 (severity of illness) and 7 (placeholder for extension of the code to increase specificity) . Not only must new software be installed and tested, but medical practices must provide training for physicians, staff members, and administrators. They will also need to develop new practice policies and guidelines, and update paperwork and forms. Practices should also create crosswalks that will convert their most frequently used ICD-9 codes to the ICD-10 equivalents.
Although the undertaking can seem overwhelming, especially to small practices, technology can be a big help. Practices should check with their EHR vendors to make sure they understand the data storage requirements for the new code set; seek online training available through association websites and software-based instruction; and invest in additional technology, such as patient kiosks, to boost productivity.
Language versions 
Language versions should not be confused with clinical versions. ICD has been translated into 42 languages.
