In short, it makes learning ICD-10 a pleasant experience.The full training package consists of 28 sections, taking approximately 40 hours to complete. Coders undertaking the full training will learn about classification context, how to use ICD-10 for morbidity and mortality coding, pitfalls in coding and analysis, basic medical science, statistical presentation of coded data, confidentiality and certification of causes of death.Basic introductory training on how to code with ICD-10 and how to avoid major errors in coding takes approximately 2 hours.

Managers, epidemiologists and others who don't need to code, but who nevertheless need to understand the process involved, can gain the information they require by spending the 5 hours needed to complete the introductory section of the tool and working through chapter summaries.
