Classifications
Here in the United Kingdom we use 2 classifications, ICD-10 to assign codes for diagnosis of disease like Hypertension (I10X) or appendicitis (K37X) and OPCS to assign codes for the procedures that are carried out during a patient's admission. These could be diagnostic (scans/biopsies) or therapeutic (hysterectomies, grafting) procedures.
ICD-10 Classification
International Classifications of Diseases, Tenth Revision
The World Health Organisation publish the ICD-10 classifications and NHS Digital on their websites state that "The International Classification of Diseases (ICD) is designed to promote international comparability in the collection, processing, classification, and presentation of mortality statistics. This includes providing a format for reporting causes of death on the death certificate. The reported conditions are then translated into medical codes through use of the classification structure and the selection and modification rules contained in the applicable revision of the ICD, published by the World Health Organization (WHO). These coding rules improve the usefulness of mortality statistics by giving preference to certain categories, by consolidating conditions, and by systematically selecting a single cause of death from a reported sequence of conditions. The single selected cause for tabulation is called the underlying cause of death, and the other reported causes are the nonunderlying causes of death. The combination of underlying and nonunderlying causes is the multiple causes of death. The ICD has been revised periodically to incorporate changes in the medical field. The Tenth Revision (ICD-10) differs from the Ninth Revision (ICD-9) in several ways although the overall content is similar: First, ICD-10 is printed in a three-volume set compared with ICD-9’s two-volume set. Second, ICD-10 has alphanumeric categories rather than numeric categories. Third, some chapters have been rearranged, some titles have changed, and conditions have been regrouped. Fourth, ICD-10 has almost twice as many categories as ICD-9. Fifth, some fairly minor changes have been made in the coding rules for mortality."
OPCS Classifications of Interventions and Procedures
The OPCS-4 Classification is used in the United Kingdom and is published and created by NHS Digital. And on their website they state that "OPCS-4 is a statistical classification for clinical coding of hospital interventions and procedures undertaken by the NHS. The classification is mandatory for use by health care providers to support various forms of data collections for secondary uses. The Terminology and Classifications Delivery Service within NHS Digital has responsibility for the support, maintenance, development and licensing of OPCS-4 which is governed by Crown Copyright. Details are given below of Version 4.9, which is due for implementation on 1 April 2020. This information standard is published under section 250 of the Health and Social Care Act 2012. An Information Standards Notice (see below) provides an overview of scope and implementation timescales, and the other listed documents provide further detail for those who have to implement the information standard. Update 5 December 2019: The latest release (DCB0084 Amd 18/2019) was published on 8 October 2019. Since then, the need for a small change to a supporting document has been identified and a Corrigendum has been issued. Note that there is no impact on either the published Requirements Specification or the Implementation Guidance; however an updated Summary of Changes has been published."
My books
Above shows what your books look like when you receive them; but they are like I said the tools of the coders trade. So I thought you might be interested to see what my ICD-10 books look like after a couple of years of use. As you can see the covers are missing and I have written notes as coding prompts for myself.
