Article Overview
This article is a coding education piece focused on medical decision-making (MDM) and how it is used to support evaluation and management level selection. It walks through the major components of MDM, defines key terminology, and summarizes the general framework used to assess complexity, data, and risk. The article is relevant to coders, auditors, and clinicians who document or evaluate office, outpatient, hospital, emergency, facility, home, care management, and related services.
Why This Topic Matters
Accurate MDM selection affects how evaluation and management services are supported in documentation and reviewed in coding workflows. Understanding the general structure of MDM helps coding professionals apply documentation more consistently and recognize what types of information contribute to the overall level.
Article Sections
-
Introduction
Introduces the topic of medical decision-making and explains that the article will define key terms and summarize a simplified selection approach.
-
What is MDM?
Defines medical decision-making and distinguishes it from other parts of the encounter documentation. It also introduces the types of services that may involve MDM.
-
The levels of MDM
Lists the general levels used in MDM and explains that each level is built from multiple components.

Component 3: Risk of complications and/or morbidity or mortality of patient management
Explains the third MDM component and describes the broad categories of management risk considered in MDM selection.
-
Determining the level of MDM
Summarizes how the three components are combined to determine the overall level of MDM.
