Background

Healthcare Resource Groups (HRGs) are the ‘currency’ of Payment by Results (PbR) for admitted patient care, outpatient procedures and A&E attendances. Complications & Comorbidities (CC) lists, maintained by NHS England’s National Casemix Office, are an integral part HRG design.

SCATA was asked by the National Casemix Office to review the ICD-10 diagnosis codes for conditions which, where a patient was undergoing care requiring anaesthesia input, the patient would be expected to consume additional resources from an anaesthesia perspective.

Secondary diagnoses on the Complications and Comorbidities lists have a score of either 1 or 2 depending on how significant an impact on resource usage, with 2 being more significant.
