For procedural code as used in computer programming, see [Procedural programming](/source/Procedural_programming). **Procedure codes** are a sub-type of medical classification used to identify specific [surgical](/source/Surgery), [medical](/source/Medical_procedure), or [diagnostic interventions](/source/Diagnosis). The structure of the codes will depend on the classification; for example some use a numerical system, others alphanumeric. ## Examples of procedure codes ### International - [International Classification of Primary Care](/source/International_Classification_of_Primary_Care) (ICPC-2), as well as procedure codes; ICPC-2 also contains diagnosis codes, reasons for encounter (RFE), and process of care. - [International Classification of Procedures in Medicine](/source/International_Classification_of_Procedures_in_Medicine) (ICPM) and [International Classification of Health Interventions](/source/International_Classification_of_Health_Interventions) (ICHI)[1] - [SNOMED CT](/source/SNOMED_CT) ### North American - [Canadian Classification of Health Interventions](/source/Canadian_Classification_of_Health_Interventions) (CCI) (used in Canada.
