OPCS-4, or more formally OPCS Classification of Interventions and Procedures version 4, is the procedural classification used by clinical coders within National Health Service (NHS) hospitals of NHS England, NHS Scotland, NHS Wales and Health and Social Care in Northern Ireland. It is based on the earlier Office of Population Censuses and Surveys Classification of Surgical Operations and Procedures (4th revision), and retains the OPCS abbreviation from this now defunct publication.
