Guidelines and revision of Emergency Department Services E/M Codes 99281-99285

E/M codes with different levels of services require a medically-appropriate history and/or physical exam. The reporting physician, or another qualified health care professional, will determine the nature and extent the history and/or the physical examination. The care team might collect information and patient or caregivers may also provide information (e.g., via an electronic health record portal or questionnaire), this information is then reviewed by the reporting doctor or qualified healthcare professional. In determining the E/M service code level, it is not important to consider the extent of your history or physical examination.

Based on the following, you can choose the right level of E/M services.

1. The MDM level as it is defined for each service.


2. The total time spent on E/M services at the date of the encounter.

Guidelines for Choosing the Right Level of Service Based On Medical Decision Making

There are four types of MDM: low, medium, high, and straightforward. 99211 and 99281 are not eligible for the MDM level.

MDM involves diagnosing, assessing a condition’s status, and/or choosing a management option. MDM can be described by three elements. These elements are:

The complexity and number of problems that will be addressed during the encounter.

The data will be reviewed and analyzed.

Management of patients is fraught with complications, morbidity, or death.
