The International Classification of Diseases (ICD) has continued to evolve as a foundational system for documenting diseases, diagnoses, signs, and symptoms across healthcare. The 11th revision, ICD-11, was adopted by the World Health Organization (WHO) and officially came into effect on January 1, 2022, modernizing the system for use in electronic health applications and information systems.
A key feature of ICD-11 is its harmonization with the Systematized Nomenclature of Medicine–Clinical Terms (SNOMED-CT), a separate but complementary clinical terminology system.
Although related, ICD-11 and SNOMED-CT serve different purposes and are structurally distinct in their levels of complexity.
ICD-11 is primarily a classification system, organizing diagnoses into standardized categories used for reporting, statistics, and reimbursement. SNOMED-CT, by contrast, is a much larger clinical terminology with hundreds of thousands of individually defined concepts, each representing a single, precise meaning rather than a broad classification.
This distinction matters for medical coders in practice: ICD-11 codes support billing, population health reporting, and mortality/morbidity statistics, while SNOMED-CT supports detailed clinical documentation, decision support, and interoperability between electronic health record systems.
Medical coders trained in anatomy, physiology, and clinical terminology are positioned to work confidently across both systems. Earning the Certified Professional Coder (CPC) credential from the American Academy of Professional Coders (AAPC) remains the standard credential for demonstrating this expertise.
Medical coders translate healthcare diagnoses, procedures, and services into standardized alphanumeric codes, working from physician notes and lab results to support accurate medical records and billing.
