Do both the 1995 and 1997 guidelines have the same number of levels of exam?

Both the 1995 and 1997 guidelines for evaluation and management (E/M) services do indeed have the same number of levels of exam. This consistency is important because it provides a standardized framework for coders and healthcare providers to use when documenting and billing for patient visits.

The two sets of guidelines outline a variety of exam levels, allowing practitioners to classify the complexity of patient encounters systematically. While the approach to determining the level of service can vary slightly between the two sets due to differences in the criteria for each level, the number of levels remains unchanged. This standardization helps ensure clarity and uniformity in reporting and coding practices, making it easier for professionals in the cardiovascular and thoracic surgery fields to effectively navigate billing processes.

The other options suggest variations either in the quantity of levels or criteria, which would introduce unnecessary complexity and confusion into coding practices. Maintaining the same number of levels across the two sets of guidelines streamlines the process for coders and clinicians alike.
