Which of the following are used for coding diagnoses and procedures?

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

Answer: (D)

Coding diagnoses and procedures relies on multiple systems that play different roles in documentation, reporting, and billing. ICD-9-CM provided codes for both diagnoses and procedures, offering a way to document diseases and the procedures performed. ICD-10-PCS is the U.S. standard for inpatient procedure coding, delivering a more detailed and precise description of procedures in the hospital setting. SNOMED-CT is a broad clinical terminology used within electronic health records to capture detailed clinical concepts, including diagnoses and procedures, and it can be mapped to ICD codes for reporting and billing. Because each system covers coding of diagnoses or procedures in its own context, all of the above are used for coding diagnoses and procedures.
