ICD-10-CM Review

ICD-10-CM is a set of codes used to identify diagnoses. It can also be used to code signs, symptoms, and circumstances surrounding healthcare. Although hospitals (or inpatient providers) and physicians (or outpatient providers) use different code sets to code procedures, all providers use ICD-10-CM to code diagnoses, so it is a critically important set of codes for every coder to know.

The ICD-10-CM is a clinical modification (hence the “CM”) of ICD-10. ICD-10, which is copyrighted by the World Health Organization, is used to code and classify mortality data from death certificates.

The clinical modification is described by the Centers for Disease Control as a “significant improvement over ICD-9-CM and ICD-10.” Why is that? Click the link to read the description of ICD-10-CM on the CDC’s website and find out.
