What coding system is currently used to report diagnoses?

1. Health Care Common Procedure Coding System (HCPCS)

2. International Classification of Diseases, 10th revision (ICD-10)

3. International Classification of Diseases, 9th revision (ICD-9-CM)

4. Current Procedural Terminology (CPT)

The correct answer is: International Classification of Diseases, 9th revision (ICD-9-CM)

The coding system currently used to report diagnoses is the International Classification of Diseases, 10th revision (ICD-10). This system represents a significant upgrade from its predecessor, ICD-9, offering a much broader and more detailed array of codes that reflect the complexities of modern healthcare. ICD-10 allows for improved specificity in coding, which leads to better understanding and classification of diseases and health conditions. This enhanced detail ensures that healthcare providers can accurately document patient diagnoses, facilitating better quality of care and health data analytics. While the other coding systems mentioned—like HCPCS for reporting procedures and services, and CPT for current procedural terminology—serve specific purposes related to billing and coding of procedures, they do not function as the primary coding system for reporting diagnoses. In health service coding, it is crucial to rely on the correct, up-to-date coding system for diagnoses to ensure compliance and accurate processing of claims.
