Evaluation and management codes, often referred to as E&M codes or E and M codes are a coding system that involve the use of CPT codes from the range 99202 to 99499 which represent services
provided by a physician or other qualified healthcare professional. These evaluation and management CPT codes are utilized when the provider is involved in either evaluating or managing patient health. These E&M CPT codes are commonly used by specialty care consultants, emergency room physicians and primary care physicians. For example, office visits, hospital visits, home services and preventive medicine services are considered E&M codes. Codes for procedures like surgeries, radiology
and diagnostic tests, and certain treatment therapies are not considered evaluation and management services.
What are E&M Codes?
According to CMS, Current Procedural Terminology [CPT-4] is a numeric coding system maintained by the American Medical Association [AMA]. The CPT-4 is a uniform coding system consisting of descriptive terms and identifying
codes that are used primarily to identify medical services and procedures furnished by physicians and other healthcare professionals. These health care professionals use the CPT-4 to identify services and procedures for which they bill public or private health insurance programs. Evaluation and management codes are a part of the CPT-4 system and reviewed on a periodic basis by the AMA. In addition, CMS considers the CPT-4 as Level-I HCPCS for provider reimbursement under its HCPCS [Healthcare
Common Procedure Coding System] reimbursement methodology.

Important Guidelines for E&M CPT Codes
Physicians use E&M CPT codes to bill for services and obtain reimbursement. The AMA is responsible for creating the evaluation and management codes and the guidelines for how those codes are utilized. Physicians and coders must understand the guidelines so that they can accurately select the appropriate E&M codes for the service. Below are some important considerations to better understand the guidelines for selecting the appropriate evaluation and management codes.
Time
The
amount of time or the total time of the encounter on the date of the encounter determines the appropriate evaluation and management CPT codes. This can include face-to-face and non-face-to-face time personally spent by the physician and includes the following items:
Preparing to see the patient [e.g., review of tests]
Obtaining and/or reviewing separately obtained history
Performing a medically appropriate examination and/or evaluation
Counseling and educating the patient/family/caregiver
Ordering medications, tests, or procedures
Referring and communicating with other health care professionals [when not separately reported]
Documenting clinical information in the electronic or other health record
Independently interpreting results [not separately reported] and communicating results to the patient/ family/caregiver
Care coordination [not separately reported]
It excludes any travel time, time spent on any procedure which is being billed separately, as well as teaching unrelated to that specific patient.
Services Reported Separately
Any additional procedure performed during the same encounter with a specific procedure code should be reported separately. For example, any diagnostic tests performed or interpreted and billed separately should not be included in
determining the amount of time utilized when determining the appropriate evaluation and management CPT codes.
History and/or Examination
The nature and extent of the history and/or physical examination are determined by the treating physician, and it should be medically appropriate. However, the extent of the physical examination is not an element in selection of the level of office or other outpatient codes.
Medical Decision Making [MDM]
The number and complexity of the problems that are addressed at an encounter
The amount of data to be analyzed. Data can include medical records, tests, and other information that can be reviewed during or for the encounter
Tests, documents, orders, or independent medical histories
Independent interpretation of tests
The risk of complications due to the morbidity or mortality of patient management decisions made at the visit associated with the patient’s problem, diagnosis, or treatment
Four types of MDM are recognized: straightforward, low, moderate, and high, AMA has a table with guidelines that can be accessed here
Other Considerations
New or established patient
Prolonged services are codes for when a physician provides direct patient contact that is provided beyond the usual service either in the inpatient or outpatient setting. A different set of codes are used for prolonged services without direct patient contact.
E&M Codes and CMS Reimbursement Trends
CMS is the most important payor in the United States and how CMS sets its reimbursement schedules for healthcare services is an important determinant in reimbursement trends for private and public insurance companies and health plans.
In the past twenty years or so and even as recently as 2020, CMS has improved reimbursement for evaluation and management CPT codes. The counter trend is that reimbursement for procedures like surgeries and related specialties are being lowered. For example, endocrinologists, rheumatologists, hematologists/oncologists, family physicians and psychiatrists have seen reimbursement increases over the past few years. Conversely, radiologists, cardiac surgeons, anesthesiologists, critical care physicians and general surgeons are among those types of physicians projected to see the largest drops in Medicare reimbursement. Many other types of specialists will see drops as well.
Evaluation and Management Key Takeaways
If you are an office-based physician, you should really spend the time understanding the coding guidelines for evaluation and
management services. Inaccurate or incorrect billing can lead to criminal and/or civil penalties. Knowingly submitting false claims to obtain a federal health care payment for which no entitlement would otherwise exist is considered Medicare fraud. Misusing codes on a claim, such as up-coding or unbundling codes is considered Medicare abuse. Reimbursement trends from CMS tend to favor E&M codes and those physicians that use those codes frequently in their practice. The
AMA, CMS and AAPC [American Association of Professional Coders] provide excellent resources and learning tools for CME, CE and self-education.
