The ICD-9-CM Coding Handbook is the only guide published in collaboration with the Central Office on ICD-9-CM of the American Hospital Association. The Central Office is the official industry body that prepares the AHA Coding Clinic for ICD-9-CM. The Handbook helps coders understand the principles behind the classification system so they can apply the official coding advice found in the ICD-9-CM Coding Manual. Academic and in-service instructors can easily arrange course outlines and study exercises around Handbook chapters to train new and experienced coders. Each Handbook contains 100-plus exercises and review questions plus, 269 case summary exercises that are based on real patient records.
