Which of the following is NOT a component of the HCPCS Level II book?

The correct response highlights that ICD-10-CM codes are indeed not a component of the HCPCS Level II book. The HCPCS Level II coding system is specifically designed to contain codes for services, equipment, and supplies not included in the CPT coding system. It includes an Alphabetic Index, which allows users to look up codes based on descriptions, and a Tabular List that organizes these codes numerically for easier reference. Additionally, the HCPCS Level II book includes Symbols and Conventions that provide important information on how to interpret and use the codes. In contrast, ICD-10-CM codes are part of a different coding system focused on diagnoses and are found in the ICD-10-CM codebook, not in the HCPCS Level II structure.
