Which statement accurately reflects the classification systems used in the United States?

The accurate classification of systems used in the United States relies on how the International Classification of Diseases (ICD) and its modifications are applied. The ICD codes, in their original form, serve primarily to classify diseases and health conditions, and they are instrumental in coding morbidity. The Clinical Modification (CCM), specifically the ICD-10-CM, is tailored for morbidity data relating to clinical settings.

The first statement inaccurately claims that ICD codes exclusively handle mortality data. While ICD codes do encompass codes for causes of death, particularly in their ICD-10 version, they are not limited to just mortality but instead also cover a broader range of diagnoses and health problems.

The second statement indicates that ICD, Clinical Modification codes are responsible for morbidity data. This statement is mostly true, as these codes are indeed used to represent diverse health conditions and diseases within clinical environments, thereby capturing a wide array of morbidity data.

Therefore, the correct assessment is neither statement presented accurately frames the relationship between ICD codes and their specific applications in mortality and morbidity contexts. Thus, the conclusion is that both statements are incorrect, making them mutually exclusive in their accuracy.
