&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;OPCS-4&amp;#039;&amp;#039;&amp;#039; (Office of Population Censuses and Surveys Classification of Interventions and Procedures, version 4) is a [[medical classification]] used by the [[National Health Service]] (NHS) in the [[United Kingdom]]. It is used to code surgical, diagnostic and therapeutic procedures and interventions.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
&lt;br /&gt;
OPCS-4 is the latest version of a system that has been in use within the NHS since the 1980s. It was developed by the [[Office of Population Censuses and Surveys]], a former department of the UK government, which has since been incorporated into the [[Office for National Statistics]].&lt;br /&gt;
&lt;br /&gt;
== Usage ==&lt;br /&gt;
&lt;br /&gt;
OPCS-4 is used throughout the NHS in England, Scotland, Wales and Northern Ireland. It is used in a variety of settings, including hospitals, primary care and community health services. The codes are used for a variety of purposes, including clinical coding, [[health informatics]], [[healthcare quality]] assessment, [[healthcare resource allocation]], and [[healthcare planning]].&lt;br /&gt;
&lt;br /&gt;
== Structure ==&lt;br /&gt;
&lt;br /&gt;
OPCS-4 codes are alphanumeric, and consist of a letter followed by three numbers. The letter indicates the section of the classification, and the numbers indicate the specific procedure or intervention. There are 19 sections in total, covering a wide range of medical and surgical procedures.&lt;br /&gt;
&lt;br /&gt;
== Updates ==&lt;br /&gt;
&lt;br /&gt;
OPCS-4 is updated annually by the [[NHS Digital]] to reflect changes in medical practice. The updates are based on feedback from users of the system, and are approved by the [[NHS Classification Service]].&lt;br /&gt;
&lt;br /&gt;
