ICD-10-CM
The ICD-10 Clinical Modification (ICD-10-CM) is a set of diagnosis codes used in the United States of America. It was developed by a component of the U.S. Department of Health and Human services, as an adaption of the ICD-10 with authorization from the World Health Organization. In 2015, ICD-10-CM replaced ICD-9-CM as the federally mandated classification. Annual updates are provided. Development Since 1979, the US had required ICD-9-CM codes for Medicare and Medicaid claims, and most of the rest of the medical industry in the US followed suit. On January 1, 1999, the ICD-10 (without clinical extensions) was adopted for reporting mortality, however, ICD-9-CM continued to be used for morbidity. During that time, the U.S. National Center for Health Statistics (NCHS) received permission from the WHO to create a clinical modification of the ICD-10. ICD-10-CM adapted ICD-10 in the following ways: Allow the capture of information for ambulatory and managed care encounters Expand available injury codes Combine codes for diagnosis/symptoms to reduce the number of codes needed to describe a problem fully Provide additional sixth and seventh digit classifications Add classifications specific to laterality Refine classification for increased data granularity Adoption Adoption of ICD-10-CM was slow.
