SECONDARY DIAGNOSIS (ICD) is the International Classification of Diseases (ICD) code used to identify the secondary PATIENT DIAGNOSIS.

For Commissioning Data Sets (CDS) purposes it is recommended that multiple Diagnoses are recorded and the CDS XML Schema (CDS Version 6 onwards) has been designed to carry as many Diagnoses as required.

SECONDARY DIAGNOSIS (ICD) is used by the Secondary Uses Service to derive the Healthcare Resource Group 4. Failure to correctly populate this data element is likely to result in an incorrect Healthcare Resource Group, usually resulting in lower levels of healthcare resource.
