What type of codes does the International Classification of Diseases, 10th Revision primarily include?

The International Classification of Diseases, 10th Revision (ICD-10) primarily includes alphanumeric codes, which consist of both letters and numbers. This coding structure allows for a more extensive classification of diseases and conditions as it combines both numeric and alphabetic elements to accommodate a wide range of medical diagnoses.

The use of alphanumeric codes increases the complexity and specificity of the classification, enabling healthcare providers to capture detailed information about patient conditions. This level of detail is essential for accurate reporting, statistical analysis, and healthcare administration, which is why alphanumeric codes are utilized rather than purely numeric codes, correlative codes, or textual descriptions.
