A classification system, such as the International Classification of Diseases or the Diagnostic and Statistical Manual of Mental Disorders, is a health information standard that involves the arrangement or categorization of like or related entities; the relationally grouped details of classification systems are useful to providers in the delivery of care because they provide clinical information output that can be used in patient diagnosis and treatment. Conversely, a terminology, such as the Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT®) or Current Procedural Terminology (CPT®), is a comprehensive set or collection of terms that represents a particular system of concepts for a certain subject area or field of interest. As such, terminologies as a standard are well-suited to capturing provider input of detailed clinical information into patient records, which, in turn, provides an ideal framework for data reporting and data comparison across records.
To prepare for this Discussion: Consider the particulars of SNOMED CT®, CPT®, and HCPCS—including their respective developments and the organizations behind those efforts, as well as their specific uses and applications within health care. You will also differentiate the unique structural and functional specifics of each of these standardized systems of health information representation.
• How can you differentiate the structural, functional, and developmental specifics of previous and current versions of the Systematized Nomenclature of Medicine (SNOMED)?
• How would you identify the structural, functional, and developmental specifics of CPT’ and HCPCS?
