Which of the following is a characteristic of coding conventions in ICD-10-CM?

Coding conventions in ICD-10-CM are essential rules and guidelines that inform medical coders how to properly use the coding system. These conventions help in ensuring uniformity and accuracy in the documentation of diagnoses and services. They include instructions and advice on elements like the structure of codes, how to sequence codes, and the proper use of specific notations, all of which guide coders in minimizing errors and ensuring the codes reflect the patient's condition correctly.

The other options do not accurately describe coding conventions. While coding guidelines may influence how diagnoses are coded, coding conventions specifically refer to the established practices and instructions within the coding system itself, rather than the broader guidelines. The listing of all possible diagnoses is not a function of coding conventions; rather, it is accounted for through the coding manuals. Similarly, justifying billing practices and defining reimbursement rates are not part of the coding conventions but relate to separate aspects of medical billing and insurance processes.
