What coding system, abbreviated ICD, is used to classify diseases and health problems?

• A. International Classification of Diseases (ICD)
• B. Systematized Nomenclature of Medicine (SNOMED)
• C. Current Procedural Terminology (CPT)
• D. Healthcare Common Procedure Coding System (HCPCS)

Answer: (A)

The main idea is that ICD is the standard system used to classify and code diagnoses and health problems. It provides codes that represent diseases and other health conditions, which allows consistent documentation, billing, and statistical reporting across different healthcare settings and countries. ICD is maintained by the World Health Organization and is used worldwide; in the United States, ICD-10-CM is used for diagnoses, while ICD-10-PCS is used for procedures. The other coding systems serve different purposes: SNOMED is a detailed clinical terminology for recording patient findings and clinical data, CPT is used for coding medical procedures and services for billing, and HCPCS covers other procedures, supplies, and services not included in CPT.
