The International Classification of Diseases, 10th revision (ICD-10) is the coding system currently used to report diagnoses. This system was adopted in the United States to replace ICD-9, which had limitations in terms of the number of codes and the specificity available for various health conditions. ICD-10 offers a much broader and more detailed range of codes, allowing for better documentation and reporting of diagnoses.

The ICD-10 is essential in various contexts, including healthcare billing and clinical documentation. It provides a standardized way to encode diagnoses, which in turn facilitates accurate coding for reimbursement, research, and public health statistics. Its use enables healthcare providers to categorize health conditions with a greater degree of precision, which can improve patient care and tracking of diseases.

In contrast, although other coding systems mentioned are crucial, they serve different purposes. The Health Care Common Procedure Coding System (HCPCS) focuses on reporting healthcare procedures and services rather than diagnoses, while Current Procedural Terminology (CPT) is even more specialized, dealing specifically with medical procedures rather than diagnoses. ICD-9-CM, while previously used, has been outdated since the implementation of ICD-10 and does not meet current clinical or procedural needs.
