Which of the following is NOT a coding guideline in the CPT codebook?

The assertion that documenting the procedure’s time and date is not a coding guideline in the CPT codebook highlights an important aspect of medical coding. While it is essential for healthcare providers to maintain comprehensive records, including the time and date of procedures, these elements are part of clinical documentation rather than the coding process itself.

In contrast, the other choices represent core coding guidelines established within the CPT codebook. Codes must indeed be selected from the appropriate sections to ensure accurate representation of the services performed. Utilizing unlisted codes is recommended when a specific service or procedure does not have an assigned code, emphasizing the importance of specificity in coding. Additionally, the assignment of modifiers is an essential coding practice that provides additional information about the service rendered, such as whether a procedure was altered in some way.

Therefore, while documenting time and date supports quality patient care and informed clinical decisions, it does not fall under specific coding guidelines prescribed in the CPT codebook, making it the correct answer.
