Final answer:
Clinical data representation systems such as ICD-9-CM, SNOMED-CT, and ICD-10-PCS are standardized codes used in healthcare. These codes are vital for diagnostics, treatment planning, billing, and epidemiological studies. ICD codes are commonly found in patient medical records and on laboratory requisition forms.
Step-by-step explanation:
The question pertains to clinical data representation systems used in the healthcare industry. The options listed: a. ICD-9-CM, b. SNOMED-CT, c. ICD-10-PCS are all different types of standardized terminologies or codes.
Specifically, ICD codes are used to classify diseases, and they play a critical role in an array of healthcare-related activities, such as diagnostics, treatment planning, medical billing, and epidemiological research.
ICD-9-CM and ICD-10-PCS are parts of the International Classification of Diseases, with ICD-9-CM being the Clinical Modification of the ninth revision, and ICD-10-PCS being the Procedure Coding System for the tenth revision.
On the other hand, SNOMED-CT (Systematized Nomenclature of Medicine -- Clinical Terms) is a comprehensive, multilingual clinical healthcare terminology used to create a standardized, actionable, and shareable medical record.
In clinical settings, ICD codes are found in patient medical records and on laboratory requisition forms. Medical professionals use these codes for a variety of purposes, including ordering and verifying laboratory tests, documenting diagnoses on medical records, or determining the cause of death on death certificates. Public health professionals may also use these codes for morbidity and mortality statistics.
