National Casemix Office

The National Casemix Office designs and refines classifications that are used by the NHS in England to describe healthcare activity. These classifications underpin the Payment by Results system from costing through to payment, and support local commissioning and performance management.


What is the National Casemix Office?

Our National Casemix Office (NCO) develops clinical grouping methodologies (including Healthcare Resource Groups) and software products to support the NHS.

The NCO supports Payment by Results (PbR).This system ensures a fair and consistent basis for hospital funding utilising Healthcare Resource Groups which are standard groupings of clinically similar treatments which use common levels of healthcare resource.

From April 2013, NHS England will have responsibility for directly commissioning all prescribed specialised services. The NCO, working in partnership with NHS England, supports this process by developing software solutions which assist the identification of such activity.

The National Casemix Office enables the NHS to:

  • support activity costing:to inform the national tariff setting processes
  • report on patient activity information:to ensure that providers are paid for the services they deliver
  • provide information to support epidemiological studies and service planning
  • enable providers and commissioners to use HRGs to benchmark and performance manage

What does the National Casemix Office produce?

We have a comprehensive downloads section where users can access Costing and Payment Groupers in addition to the Prescribed Specialised Services Identification Tool and user support documentation.
