Medical coding and classification systems are expected to become increasingly important in the health care sector. Medical coding has various interrelated codes like ICD, CPT, ENM codes. ICD and CPT codes provide specification of the disease and the procedure respectively where the ENM code is a combined systems of both and provides the hospital care of the patient. ICD (International Statistical Classification of Diseases and Related Health Problems) is the international “standard, diagnostic tool for epidemiology, health management and clinical purposes”. The aim of this study is to assess the accuracy of diagnostic coding (ICD10) in patient discharge summary and to also determine the causes of error in diagnostic coding. The retrospective observational study was conducted in a 200 bedded tertiary care teaching hospital. From discharge summary data was collected with diagnostic codes and documented in data collection form. Hard copy data were transferred to electronic database for further evaluation and analysis using ICD10 Guideline. This study specially provides us clear information about different causes of coding errors and its outcome. The impact of wrong coding will affect the economic benefit of the hospital as well as in various resource of epidemiological study.
