CLINICAL CLASSIFICATION CODE

A unique identifier for a CLINICAL CLASSIFICATION, for example this could be an OPCS-4 code or a Read code.

The codes for both OPCS-4 and Read are maintained by NHS Connecting for Health.

This could also be a DIAGNOSIS.

See Clinical Coding for International Classification of Diseases (ICD-10) and Read Coded Clinical Terms.

See Clinical Coding.

Diagnoses should be classified where possible using ICD-10 or other classification codes approved centrally for mapping to ICD-10 codes. Clinical Terms (The Read Codes) can be used in addition to ICD-10 codes for Patient Diagnosis. However Clinical Terms (The Read Codes) are not accepted for the purposes of central HES data, where ICD-10 is mandatory.

ICD-10 diagnostic codes are at least four characters in length. The first character is always alphabetic. Where an undivided three character code is used, the fourth character must be filled with 'X'.

Fifth characters should be used in accordance with the guidance in Introduction. Where they are not used the character must be filled with a '-'. The sixth character of the code is used to designate an asterisk or dagger indicator in ICD-10; it may be an 'A' or 'D'.
