Show synopsis The most widely used publication for teaching ICD-9-CM to entry-level and experienced coders. It is designed for self-study and reference. The ICD-9-CM Coding Handbook is the only edition published in cooperation with the Central Office on ICD-9-CM of the American Hospital Association. [The Central Office is an official industry body that participates in the editorial development, preliminary testing, and national committee and congressional hearings on ICD-9 and ICD-10 specifications and rules. Central Office staff are the nation's experts on coding protocols. ICD-9-CM Coding Handbook provides more than 100 review exercises interspersed throughout the text and at the end of the chapters. These exercises describe additional information about a patient's background or present condition, and allow coders to practice their coding skills on examples that closely resemble actual patient records. The answers to these exercises not only provide the correct codes and principal diagnoses, they also explain why a particular code is correct or what information is most important in a certain case.
