ICD-10 Strikes Back
Believe it or not, there is a method to the madness of ICD-10. The system was developed by the World Health Organization (WHO) as a means of standardizing the categorization of diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases.
ICD-6, adopted in 1949, was the first version of ICD that was deemed suitable for morbidity reporting. The combined code section for injuries and their associated accidents was split into two: a chapter for injuries, and a chapter for their external causes. With use for morbidity there was a need for coding mental conditions, and for the first time a section on mental disorders was added.
Work on ICD-10 — the tenth revision of the system — began in 1983. It was officially copyrighted by WHO in 1990, though it wasn’t actually completed until 1992. It was then adopted relatively quickly by many countries of the world, starting with Australia in 1998. Today, ICD-10 is the most widely used statistical classification system for diseases in the world.
For numerous reasons, but particularly due to the special interest groups that affect policy, the United States wasn’t able to get on board until August 2008. At that time, the Department of Health and Human Services proposed that ICD-10 be adopted in America — a move that was formalized in January 2009, establishing ICD-10 as the new national coding standard, with an implementation date of October 1, 2013.
And if the prospect of changing over to ICD-10 wasn’t imposing enough, ICD-11 is “scheduled” to become the new standard in 2017 — though with the numerous delays in getting ICD-10 onto the books, it’s likely that ICD-11 will be pushed back for at least a few years.
