Which of the following is NOT one of the CMS requirements for E/M encounter documentation?

The correct response identifies that insurance verification confirmation is not a requirement by the Centers for Medicare & Medicaid Services (CMS) for Evaluation and Management (E/M) encounter documentation.

CMS has established specific criteria outlining what must be documented during an E/M visit to ensure appropriate billing and coding. These requirements typically include the assessment or diagnosis, plan of care, and essential details like the date of service and provider signature, which verify who provided the service and when.

Insurance verification is a prerequisite for ensuring eligibility and benefits but does not form a part of the immediate clinical documentation requirements needed for an E/M encounter under CMS guidelines. Therefore, while verifying insurance is essential for administrative functions and the overall billing process, it is not included in the core documentation requirements that guide clinical encounters.
