Offering a comprehensive tool for self-assessment, the 2013 CODING CASE STUDIES WORKBOOK enables coders to practice skill building using all code sets–ICD-9-CM, ICD-10-CM, ICD-10-PCS, CPT and HCPCS–in all settings. This comprehensive workbook provides a variety of exercises applicable to physician offices, ambulatory care, and hospital settings. Written as short case studies, exercises emphasize official coding guidelines and include clinical concepts that reflect coding examples from current practice. The rich assortment of application exercises range from basic to the intermediate/advanced level. The detailed rationale for answers allows for a more thorough understanding of the code sets, while answers to the ICD-10-CM exercises highlight the key differences between ICD-9-CM and ICD-10-CM. Special Coding Insights features provide further guidance to support the coding decision-making process.
