The aim of this research work was to identify relevant diagnosis codes available in routine electronic health records from primary and secondary care settings in the UK. We looked for relevant codes in code repositories such as the University of Cambrigdge Primary Care Unit, Manchester Clinical Codes, HDR UK National Phenomics Resource Project, Oxford-RCGP RSC, OpenSAFELY and LSHTM Data Compass. We also searched for peer-reviewed studies published via PubMed in the last 12 months for any relevant codes. Please note that these codes are not intended to be mandatory, but are to be used as a starting point for the identification of Tonsillitis in routine electronic health record. Therefore, each study may differ in the sensitivity and specificity of the coding required. - No validations available


According to NHS, tonsillitis is an infection of the tonsils at the backof your throat. It is a common childhood illness, but teenagers and adults can get it too.
