Both sets of guidelines are determined by what 3 key components?

The correct answer revolves around the key components of patient evaluation and documentation that are critical in medical auditing and coding. History, exam, and medical decision-making (MDM) are foundational aspects of determining the complexity and necessity of the medical services provided.

The history includes gathering information about the patient's past medical and surgical history, social history, and a review of systems, which all contribute to establishing a baseline for understanding the patient's health status. The examination component involves a comprehensive assessment conducted by the healthcare provider, allowing for the identification of the present condition leading to diagnosis. Medical decision-making is the process whereby the provider evaluates the complexity of the patient's health issues and decides on the appropriate course of action, including further tests, referrals, or treatments.

These three elements—history, examination, and medical decision-making—collectively inform the level of service that should be billed and the appropriate coding for that service. They reflect the thoroughness of the evaluation and how well the healthcare provider meets the standards of care established by regulations and guidelines in the medical field. Understanding these components enables auditors and coders to ensure that coding aligns correctly with the services rendered, supporting compliance and appropriate reimbursement.
