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

The term casemix means:
- the mix of cases (patients) seen by a consultant/hospital/region
- how patient care and treatments are classified into 'groups - these 'groups' provide a useful measure on which to make performance comparisons, to cost healthcare, or to fund it
The National Casemix Office (NCO) are commissioned to develop and maintain a set of casemix groupings, called Healthcare Resource Groups (HRG), which provide a clinically-endorsed view of acute healthcare activities undertaken within the English NHS. These groups are generated via the Casemix Grouper Software (the most current version is HRG4+).
HRGs are designed by clinicians to represent clinical care, within the boundaries of available, nationally mandated, data. The HRG4+ classification can acknowledge the additional resource use required when treating patients who:
- have multiple complications and comorbidities that affect the clinical input for their care
- require surgery at a very young age
- require multiple procedures undertaken at the same time, within the same hospital admission or attendance
- require surgery that utilises new devices, or innovation in the traditional clinical approach
- require more complex care
Tools and applications
Although primarily focused on traditional acute hospital services, the NCO's broadening remit has extended to cover the development of IAPT tools and software to support national patient initiatives.
It also produces software to allow Prescribed Specialised Services activity, as defined by NHS England's Clinical Reference Groups, to be identified from nationally mandated data flows.
The NCO has been commissioned to develop a Casemix Classification for Community Care - Community Health Groups - and is progressing this through the establishment of a Casemix Community Expert Reference Group, bringing together providers and commissioners of community care, along with policy, to ensure that developments are not only useful, but that they can be operationalised within the operating environment of the NHS.
What we 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.
The design framework [924.07KB] informs major stakeholders, including NHS Clinicians, the Department of Health Payment by Results team (PbR) as well as the Casemix Service, of the rules and criteria to be followed when designing classification systems.
