Which of the following is an example of a Clinical Data Representation?

• A. ICD-9-CM
• B. SNOMED-CT
• C. ICD-10-PCS
• D. All of the above

Answer: (D)

Clinical Data Representation is about encoding health information in standardized formats so computer systems can understand and share it. ICD-9-CM and ICD-10-PCS are coding systems that represent diagnoses and procedures, respectively, in a way that computers can process for reporting and billing. SNOMED-CT provides a rich clinical terminology with concepts and relationships to express detailed clinical ideas such as problems, findings, and treatments. Because each of these systems is used to encode clinical information in a consistent, interoperable way, all of them are examples of clinical data representation. So, all of the above.
