Comparing the Features of SNOMED CT and ICD

In this presentation the design features of SNOMED CT and ICD are compared. The presentation looks at the difference between the mono-hierarchical structure of ICD and the polyhierarchical structure of SNOMED CT. It also presents the differences in the way concepts are defined in the two code systems, and how each unit of meaning is uniquely identified.

After completing this presentation the student should be able to:

• Compare and contrast the features of SNOMED CT and ICD
• Explain the difference between a monohierarchical and a polyhierarchical structure
• Contrast how SNOMED CT and ICD expresses the meaning of clinical concepts/codes
• Explain how codes are defined in ICD and SNOMED CT to ensure uniqueness

• Mapping
• Other Codes

• Clinical Informatician
• Data Analyst
