CD-10-CM is the new diagnosis coding system that is being developed as a replacement for ICD-9-CM, Volumes 1 & 2.

This 2014 update of the International Statistical Classification of Diseases and Related Health Problems, 10th revision, Clinical Modification (ICD-10-CM) is being published by the United States Government in recognition of its responsibility to promulgate this classification throughout the United States for morbidity coding.

ICD-10-CM is the United States' clinical modification of the World Health Organization's ICD-10. The term "clinical" is used to emphasize the modification's intent: to serve as a useful tool in the area of classification of morbidity data for indexing of health records, medical care review, and ambulatory and other health care programs, as well as for basic health statistics. To describe the clinical picture of the patient the codes must be more precise than those needed only for statistical groupings and trend analysis.

Characteristics of ICD-10-CM

ICD-10-CM far exceeds its predecessors in the number of concepts and codes provided. The disease classification has been expanded to include health-related conditions and to provide greater specificity at the sixth and seventh character level. The sixth and seventh characters are not optional and are intended for use in recording the information documented in the clinical record.
