What does the "CM" stand for in ICD-10-CM?

The term "CM" in ICD-10-CM stands for "Clinical Modification." This designation highlights that the coding system is a modified version of the International Classification of Diseases (ICD) specifically designed for use in clinical settings. The purpose of the Clinical Modification is to provide a more detailed and precise coding framework that reflects the complexities of patient conditions and facilitates proper classification for billing and statistical purposes.

ICD-10-CM is primarily used by healthcare providers in the United States for reporting diagnoses and conditions. Its clinical modification aspect is essential as it caters to the specific needs of the U.S. healthcare system, incorporating updated codes that reflect contemporary medical understanding and practices. It allows for enhanced data collection, tracking of diseases, and monitoring of healthcare trends. This is crucial for improving patient care and managing public health effectively.
