Modifiers are used in medical coding to provide additional information about the services performed without changing the meaning of the code itself. In the context of coding multiple procedures, modifiers specify when a procedure is significantly altered by circumstances or complexity that were not included in the original procedure code.

When multiple procedures are billed, it is essential to determine if any of these procedures have been modified significantly due to the specifics of the patient's condition, how the procedures were performed, or other influences. This makes option B the most appropriate choice, as it emphasizes that modifiers should be applied when one procedure has been significantly altered.

In contrast, the other options suggest using modifiers in ways that are either too broad, misleading, or unnecessary. Using modifiers for every occurrence of multiple procedures, without consideration, can lead to inaccuracies in billing and patient records. Therefore, understanding when a procedure has been modified allows for accurate representation of the services provided.
