Which action is required to make an RFS adjustment?

To make an RFS adjustment, accessing the adjustment through RA IN RFS and making notes is essential because this process ensures that the adjustment is recorded accurately and properly documented. This method allows for systematic handling of adjustments within the RFS system. By entering the adjustment through the designated system, it maintains an organized record, which is crucial for tracking and accountability.

This action also provides a standardized approach, making it easier to audit adjustments and ensure compliance with any relevant regulations or internal policies. Documenting notes helps clarify the reasons for the adjustment, which is important for future reference and for anyone who reviews the adjustments later on.

Other options like contacting the billing department, submitting a written request to management, or aggregating pending transactions do not directly facilitate the required process for adjusting the RFS. Instead, they represent alternative actions that may not lead to the immediate and systematic correction needed within the adjustment framework of the RFS system.
