For each published interventional procedure and medical technologies guidance, we work with the Health and Social Care Information Centre (HSCIC) to provide relevant clinical coding information.

The classifications enable the provision of data on surgical procedures and technologies which forms part of national database collections for statistical and epidemiological analysis.

The Clinical Classifications Service of the Health and Social Care Information Centre is the central definitive source for clinical coding guidance and determines the coding standards associated with the classifications (OPCS-4 and ICD-10) to be used across the NHS.  The Clinical Classifications Service and NICE work collaboratively to ensure the most appropriate classification codes are provided. Clinical Classifications Service — Health and Social Care Information Centre


OPCS-4 is a mandatory NHS data standard, and its output forms part of the data flows for Commissioning Data Sets and national Hospital Episode Statistics (HES)

SNOMED CT is the standard clinical terminology for the NHS to support recording of clinical information, in a way that supports data management and analysis to support patient care, while enabling data extraction and data exchange.
