Clinical coding is the process of translating the narrative clinical information recorded in a patient's health record into standardised alphanumeric codes that can be used for statistical analysis, payment purposes, and performance measurement, and the accuracy of clinical coding has direct implications for the income received by NHS trusts and for the quality of the national data used to plan healthcare services. The International Classification of Diseases Tenth Revision, known as ICD-10, is the coding system used to represent diagnoses, symptoms, signs, abnormal findings, complaints, social circumstances, and external causes of disease and injury, and clinical coders must select the code that most accurately represents the condition treated using the guidance set out in the coding standards issued by NHS Digital. The OPCS-4 procedure code set is used to code the operative and other clinical procedures performed on patients during an episode of care, and the combination of ICD-10 diagnosis codes and OPCS-4 procedure codes is processed by the HRG grouper software to assign each episode to a Healthcare Resource Group. HRGs are the currencies used in the Payment by Results and Aligned Payment and Incentive frameworks that determine how much money a trust receives for treating different types of patients, making accurate coding a financial as well as an informational priority. Clinical coding audits compare the codes assigned by coders with a re-coding of the same records by an independent coder or auditor to assess the accuracy of the trust's coding and identify patterns of error or misunderstanding that should be addressed through training and guidance. The clinical coding profession requires specialist training, as coders must understand medical terminology, anatomy, and physiology sufficiently to interpret clinical records, and they must apply a complex set of national coding standards that are regularly updated to reflect developments in clinical practice and classification.
