ICD-10

WHO Logo.

The ICD-10 is the acronym for the International Classification of Diseases, 10th Edition corresponding to the Spanish version of the English version ICD, acronym for International Statistical Classification of Diseases and Related Health Problems and determines the classification and coding of diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances and external causes of damage and/or illness.

On June 18, 2018, the World Health Organization published the new edition of its manual of diseases. This edition (ICD-11) entered into force in 2022 to replace the one in force since 1990.

History

The ICD is published by the World Health Organization (WHO). It deals internationally for statistical purposes related to morbidity and mortality, reimbursement systems and automatic decision support in medicine. This system is designed to promote international comparison of the collection, processing, classification and presentation of these statistics. The ICD is the central classification of the WHO Family of International Classifications (WHO-FIC).).

The ICD-10 list has its origin in the «List of causes of death», whose first edition was made by the International Institute of Statistics in 1893. The WHO took over it in 1948, in the sixth edition, the first to also include causes of morbidity. To date, the current list is the tenth, and the WHO continues to work on it.

The ICD-10 was developed in 1992 and its purpose was to track mortality statistics. WHO publishes annual minor updates and major updates every three years. On June 18, 2018, the World Health Organization published the new edition of its manual of diseases. This edition (ICD-11) entered into force in 2022 to replace the one in force since 1990.

Subsequently, some countries have created their own extensions to the ICD-10 code. For example, Australia introduced its first edition, the "ICD-10-AM" in 1998; Canada published its version in 2000, the "ICD-10-CA". Germany also has its own extension, the "CIE-10-GM".

In the US, an annex was added with the procedures classification system or ICD-10-PCS. Although they already use the procedures manual, the United States and Puerto Rico are preparing for the implementation of the Procedures Classification of Diseases to start in October 2015.

Encoding

Each condition can be assigned to a category and given a code up to six characters long (in X00.00 format). Each such category may include a group of similar diseases. The following codes are used by the International Statistical Classification of Diseases and Related Health Problems:

Ch. Title Codes

I A00-B99 Certain infectious and parasitic diseases

II C00-D48 Neoplasms

III D50-D89 Diseases of the blood and blood-forming organs and other disorders affecting the immune mechanism

IV E00-E90 Endocrine, nutritional and metabolic diseases

V F00-F99 Mental and behavioral disorders

VI G00-G99 Diseases of the nervous system

VII H00-H59 Diseases of the eye and its annexes

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 Digestive system diseases

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 puerperium

XVI P00-P96 Certain conditions originating in the perinatal period

XVII Q00-Q99 Congenital malformations, deformities and chromosomal abnormalities

XVIII R00-R99 Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified

XIX S00-T98 Injuries, poisoning and some other consequences of external causes

XX V01-Y98 External causes of morbidity and mortality

XXI Z00-Z99 Factors that influence health status and contact with health services

XXII U00-U99 Codes for special situations

Mapping and cross-referencing with ICD-9

The eCIEmaps application at the Ministry of Health, Social Policy and Equality of Spain combines the terminology and classification resources of ICD-9-CM and ICD-10. Gives access to alphabetical indexes, tabular lists, supplementary classifications, appendices and regulatory manuals. It has an advanced search mode that allows you to locate alphabetic entries that point to any code.

Since 2014, eCIEmaps incorporates the draft of the first edition of the ICD10ES, which corresponds to the Spanish translation of the ICD10CM and ICD10PCS classifications, published by the National Center for Health Statistics and the Centers for Medicare and Medicaid Service, for diagnoses and procedures, respectively. The translation has been carried out by the Ministry of Health, Social Services and Equality and validated in collaboration with the autonomous communities through the ICD-10-ES Technical Unit and with the participation of clinicians and experts from 17 Scientific Societies. The ICD-10-ES will replace the ICD-9-CM as the reference classification for clinical coding in Spain from January 2016 by agreement of the Interterritorial Council on March 21, 2013. The eCIEmaps already has a mobile mapping browser (correspondences or equivalences between codes) to compare the GEM (General Equivalence Mappings) equivalences code by code between CIE9MC and CIE10ES of diagnoses and procedures.
