International Classification of Health Interventions
The International Classification of Health Interventions (ICHI) is a system of classifying procedure codes being developed by the World Health Organization. It is currently only available as a beta release for additional coding work, but not yet for operationall application. The last published version is denoted as alpha version 2.
ICHI is intentionally designed to replace the "International Classification of Procedures in Medicine" (ICPM), a system that was developed in the 1970s but which never received the same international acceptance as ICD-9. As a result, most nations developed their own standards for coding procedures and interventions incompatible to the ICPM approach.
The initial basis of WHO-ICHI (alpha version) has been largely derived from the "Australian Classification of Health Interventions" (ACHI), a portion of the Australian standard ICD-10-AM, which in turn was largely derived from ICD-10 and the United States extension ICD-9-CM. Currently (2014) the acceptance of the ICHI in the community of health care professionals might be better, but due to missing formal acceptance the spread of national variations beyond translation widely continues.
For accounting, the Australian health administration generated a code of Diagnosis-related groups which in effect again deviates from the WHO basis. The same phenomenon applies to DRG codes in Germany and other countries. Other codes generated by the UN accredited International Standards Organisation ISO defined a deviating scope. Cooperation of ISO and WHO is not detected.
