Understanding and Choosing the Correct E&M Codes for Healthcare Providers

Evaluation and Management (E&M) coding is a crucial aspect of medical billing that directly impacts the reimbursement process for healthcare providers. As of 2024, several key updates and guidelines have been introduced to streamline and improve E&M coding. At Meraki RCM Solutions, LLC, we strive to keep our clients informed about these changes to ensure accurate and efficient billing practices.

What is E&M Coding?

E&M codes are a subset of Current Procedural Terminology (CPT) codes used to describe the services provided by healthcare professionals during patient encounters. These codes cover a range of interactions, including office visits, hospital visits, consultations, and more. Accurate E&M coding is essential for proper documentation, compliance, and reimbursement.

Key Changes in E&M Coding for 2024

1. Simplification of Code Selection

One of the significant changes in E&M coding is the simplification of code selection criteria. Previously, the level of service was determined by three key components: history, examination, and medical decision-making (MDM). However, as of 2024, the focus has shifted primarily to MDM or the total time spent on the date of the encounter. This change aims to reduce administrative burdens and enhance the accuracy of code selection.

2. Medical Decision-Making (MDM)

MDM is now the primary factor in determining the appropriate E&M code. The MDM process evaluates the complexity of establishing a diagnosis and selecting a management option. It considers the number and complexity of problems addressed, the amount and complexity of data reviewed, and the risk of complications, morbidity, or mortality.

3. Time-Based Coding

For time-based coding, the total time spent on the date of the encounter includes face-to-face and non-face-to-face activities performed by the provider. This encompasses activities such as reviewing tests, documenting in the health record, and communicating with other healthcare professionals. This approach allows providers to select codes based on the total time spent, regardless of the nature of the activities performed.

4. Deletion of Level 1 Office Visit Codes

CPT codes 99201, which represented a straightforward office or other outpatient visit for a new patient, has been deleted. Providers should now use code 99202 for new patient visits requiring straightforward MDM.

5. Updates to Prolonged Services Codes

The codes for prolonged services have also been updated. CPT code 99354 for prolonged service in the office or outpatient setting has been replaced by new codes that more accurately reflect the additional time spent. These changes aim to ensure fair compensation for extended patient encounters.

Pillar-Wise Comparison of E&M Office Visit Codes

Below is a detailed pillar-wise comparison of each E&M office visit code, reflecting the current guidelines as of 2024. This will help highlight the differences in criteria and requirements for each level of service.

New Patient Visits (CPT Codes 99202-99205)

Code Medical Decision-Making Total Time Description
99202 Straightforward 15-29 minutes Low complexity, straightforward MDM
99203 Low complexity 30-44 minutes Low complexity, more detailed MDM
99204 Moderate complexity 45-59 minutes Moderate complexity, detailed analysis
99205 High complexity 60-74 minutes High complexity, comprehensive evaluation

Code Medical Decision-Making Total Time Description
99211 N/A Not applicable Minimal service, no MDM required
99212 Straightforward 10-19 minutes Brief visit, straightforward MDM
99213 Low complexity 20-29 minutes Low complexity, routine visit
99214 Moderate complexity 30-39 minutes Moderate complexity, requires significant decision-making
99215 High complexity 40-54 minutes High complexity, extensive evaluation and management

Key Considerations for Choosing the Correct Code

  • Straightforward MDM : Involves minimal complexity, typically for addressing a simple problem.

  • Low Complexity MDM : Requires a bit more data review and analysis, often involving multiple minor problems or one stable chronic illness.

  • Moderate Complexity MDM : Involves a more detailed review of data and a higher level of decision-making, often for acute illnesses with systemic symptoms or chronic illnesses with exacerbation.

  • High Complexity MDM : Requires extensive data review and analysis, high-risk decision-making, and is often used for life-threatening or significantly complex conditions.

Practical Tips for Accurate E&M Coding

To ensure compliance with the latest E&M coding guidelines, healthcare providers should consider the following tips:

  1. Document Thoroughly : Ensure that all aspects of the patient encounter are thoroughly documented, including the MDM process and total time spent.

  2. Stay Informed : Regularly update your knowledge of E&M coding guidelines and attend relevant training sessions or workshops.

  3. Utilize Technology : Leverage electronic health record (EHR) systems and coding software to streamline the documentation and coding process.

  4. Consult Experts : Work with experienced medical billing and coding professionals, like those at Meraki RCM Solutions, LLC, to ensure accurate and compliant coding practices.


The updates to E&M coding in 2024 aim to simplify the coding process and enhance the accuracy of medical billing. By understanding and implementing these changes, healthcare providers can improve their documentation practices, ensure compliance, and optimize reimbursement. At Meraki RCM Solutions, LLC, we are committed to supporting our clients in navigating these changes and achieving billing excellence.
