Details and Definition of MDM 2021

Number and Complexity of Problems Addressed at the Encounter  

One element used in selecting the level of office or other outpatient services is the number and complexity of the problems that are addressed at an encounter. 

Multiple new or established conditions may be addressed at the same time and may affect MDM. Symptoms may cluster around a specific diagnosis and each symptom is not necessarily a unique condition. 

The Comorbidities/underlying diseases, in and of themselves, are not considered in selecting a level of E/M services unless they are addressed, and their presence increases the amount and/or complexity of data to be reviewed and analyzed or the risk of complications and/or morbidity or mortality of patient management. 

The final diagnosis for a condition does not, in and of itself, determine the complexity or risk, as extensive evaluation may be required to reach the conclusion that the signs or symptoms do not represent a highly morbid condition. 

Therefore, presenting symptoms that are likely to represent a highly morbid condition may “drive” MDM even when the ultimate diagnosis is not highly morbid. The evaluation and/or treatment should be consistent with the likely nature of the condition. Multiple problems of a lower severity may, in the aggregate, create higher risk due to interaction.

Definitions for the elements of MDM


A problem is a disease, condition, illness, injury, symptom, sign, finding, complaint, or other matter addressed at the encounter, with or without a diagnosis being established at the time of the encounter

Problem addressed

A problem is addressed or managed when it is evaluated or treated at the encounter by the physician or other qualified health care professional reporting the service. 

This includes consideration of further testing or treatment that may not be elected by virtue of risk/benefit analysis or patient/parent/guardian/ surrogate choice. 

Notation in the patient’s medical record that another professional is managing the problem without additional assessment or care coordination documented does not qualify as being addressed or managed by the physician or other qualified health care professional reporting the service. 

Referral without evaluation (by history, examination, or diagnostic study[ies]) or consideration of treatment does not qualify as being addressed or managed by the physician or other qualified health care professional reporting the service.

Minimal problem

A problem that may not require the presence of the physician or other qualified health care professional, but the service is provided under the physician’s or other qualified health care professional’s supervision (see 99211). 

Self-limited or minor problem

A problem that runs a definite and prescribed course, is transient in nature, and is not likely to permanently alter health status.

Stable, chronic illness

A problem with an expected duration of at least one year or until the death of the patient. For the purpose of defining chronicity, conditions are treated as chronic whether or not stage or severity changes (eg, uncontrolled diabetes and controlled diabetes are a single chronic condition). 

“Stable” for the purposes of categorizing MDM is defined by the specific treatment goals for an individual patient. A patient who is not at his or her treatment goal is not stable, even if the condition has not changed and there is no short-term threat to life or function. 

For example, in a patient with persistently poorly controlled blood pressure for whom better control is a goal is not stable, even if the pressures are not changing and the patient is asymptomatic, The risk of morbidity without treatment is significant. Examples may include well-controlled hypertension, noninsulin- dependent diabetes, cataract, or benign prostatic hyperplasia.

Acute, uncomplicated illness or injury

A recent or new short-term problem with low risk of morbidity for which treatment is considered. There is little to no risk of mortality with treatment, and full recovery without functional impairment is expected. 

A problem that is normally self-limited or minor but is not resolving consistent with a definite and prescribed course is an acute, uncomplicated illness. 

Examples may include cystitis, allergic rhinitis, or a simple sprain. 

Chronic illness with exacerbation, progression, or side effects of treatment

A chronic illness that is acutely worsening, poorly controlled, or progressing with an intent to control progression and requiring additional supportive care or requiring attention to treatment for side effects but that does not require consideration of hospital level of care. 

Undiagnosed new problem with uncertain prognosis

A problem in the differential diagnosis that represents a condition likely to result in a high risk of morbidity without treatment. An example may be a lump in the breast.

Acute illness with systemic symptoms

An illness that causes systemic symptoms and has a high risk of morbidity without treatment. 

For systemic general symptoms, such as fever, body aches, or fatigue in a minor illness that may be treated to alleviate symptoms, shorten the course of illness, or to prevent complications, see the definitions for self-limited or minor problem or acute, uncomplicated illness or injury. 

Systemic symptoms may not be general but may be single system. Examples may include pyelonephritis, pneumonitis, or colitis.

Acute, complicated injury

An injury which requires treatment that includes evaluation of body systems that are not directly part of the injured organ, the injury is extensive, or the treatment options are multiple and/or associated with risk of morbidity. An example may be a head injury with brief loss of consciousness. 

Chronic illness with severe exacerbation, progression, or side effects of treatment

The severe exacerbation or progression of a chronic illness or severe side effects of treatment that have significant risk of morbidity and may require hospital level of care. 

Acute or chronic illness or injury that poses a threat to life or bodily function

An acute illness with systemic symptoms, an acute complicated injury, or a chronic illness or injury with exacerbation and/or progression or side effects of treatment, that poses a threat to life or bodily function in the near term without treatment. 

Examples may include acute myocardial infarction, pulmonary embolus, severe respiratory distress, progressive severe rheumatoid arthritis, psychiatric illness with potential threat to self or others, peritonitis, acute renal failure, or an abrupt change in neurologic status.

Data and Analyzed

The process of using the data as part of the MDM. The data element itself may not be subject to analysis (eg, glucose), but it is instead included in the thought processes for diagnosis, evaluation, or treatment. Tests ordered are presumed to be analyzed when the results are reported. Therefore, when they are ordered during an encounter, they are counted in that encounter. 

Tests that are ordered outside of an encounter may be counted in the encounter in which they are analyzed. 

In the case of a recurring order, each new result may be counted in the encounter in which it is analyzed. 

For example, an encounter that includes an order for monthly prothrombin times would count for one prothrombin time ordered and reviewed. 

Additional future results, if analyzed in a subsequent encounter, may be counted as a single test in that subsequent encounter. 

Any service for which the professional component is separately reported by the physician or other qualified health care professional reporting the E/M services is not counted as a data element ordered, reviewed, analyzed, or independently interpreted for the purposes of determining the level of MDM.


Tests are imaging, laboratory, psychometric, or physiologic data. A clinical laboratory panel (eg, basic metabolic panel [80047]) is a single test. 

The differentiation between single or multiple unique tests is defined in accordance with the CPT code set. For the purposes of data reviewed and analyzed, pulse oximetry is not a test

Unique Source

A unique test is defined by the CPT code set. When multiple results of the same unique test (eg, serial blood glucose values) are compared during an E/M service, count it as one unique test.

Tests that have overlapping elements are not unique, even if they are identified with distinct CPT codes.

For example, a CBC with differential would incorporate the set of hemoglobin, CBC without differential, and platelet count. A unique source is defined as a physician or qualified heath care professional in a distinct group or different specialty or subspecialty, or a unique entity. Review of all materials from any unique source counts as one element toward MDM.

Combination of Data Elements

A combination of different data elements, for example, a combination of notes reviewed, tests ordered, tests reviewed, or independent historian, allows these elements to be summed. 

It does not require each item type or category to be represented. A unique test ordered, plus a note reviewed and an independent historian would be a combination of three elements.


External records, communications and/or test results are from an external physician, other qualified health care professional, facility, or health care organization. 

External physician or other qualified health care professional

An external physician or other qualified health care professional who is not in the same group practice or is of a different specialty or subspecialty. 

This includes licensed professionals who are practicing independently. The individual may also be a facility or organizational provider such as from a hospital, nursing facility, or home health care agency.


Discussion requires an interactive exchange. The exchange must be direct and not through intermediaries (eg, clinical staff or trainees). Sending chart notes or written exchanges that are within progress notes does not qualify as an interactive exchange. 

The discussion does not need to be on the date of the encounter, but it is counted only once and only when it is used in the decision making of the encounter. It may be asynchronous (ie, does not need to be in person), but it must be initiated and completed within a short time period (eg, within a day or two).

Independent historian(s)

An individual (eg, parent, guardian, surrogate, spouse, witness) who provides a history in addition to a history provided by the patient who is unable to provide a complete or reliable history (eg, due to developmental stage, dementia, or psychosis) or because a confirmatory history is judged to be necessary. 

In the case where there may be conflict or poor communication between multiple historians and more than one historian is needed, the independent historian requirement is met. 

The independent history does not need to be obtained in person but does need to be obtained directly from the historian providing the independent information.

Independent interpretation

The interpretation of a test for which there is a CPT code and an interpretation or report is customary. This does not apply when the physician or other qualified health care professional is reporting the service or has previously reported the service for the patient. 

A form of interpretation should be documented but need not conform to the usual standards of a complete report for the test.

Appropriate source

For the purpose of the discussion of management data element Levels of Medical Decision Making), an appropriate source includes professionals who are not health care professionals but may be involved in the management of the patient (eg, lawyer, parole officer, case manager, teacher). It does not include discussion with family or informal caregivers.


The probability and/or consequences of an event. The assessment of the level of risk is affected by the nature of the event under consideration.

For example, a low probability of death may be high risk, whereas a high chance of a minor, self-limited adverse effect of treatment may be low risk. 

Definitions of risk are based upon the usual behavior and thought processes of a physician or other qualified health care professional in the same specialty. 

Trained clinicians apply common language usage meanings to terms such as high, medium, low, or minimal risk and do not require quantification for these definitions (though quantification may be provided when evidence-based medicine has established probabilities). 

For the purposes of MDM, level of risk is based upon consequences of the problem(s) addressed at the encounter when appropriately treated. Risk also includes MDM related to the need to initiate or forego further testing, treatment, and/or hospitalization. 

The risk of patient management criteria applies to the patient management decisions made by the reporting physician or other qualified health care professional as part of the reported encounter.


A state of illness or functional impairment that is expected to be of substantial duration during which function is limited, quality of life is impaired, or there is organ damage that may not be transient despite treatment. 

Social determinants of health 

Economic and social conditions that influence the health of people and communities. Examples may include food or housing insecurity.

Surgery (minor or major, elective, emergency, procedure or patient risk):  

Surgery–Minor or Major

The classification of surgery into minor or major is based on the common meaning of such terms when used by trained clinicians, similar to the use of the term “risk.” These terms are not defined by a surgical package classification. 

Surgery–Elective or Emergency

Elective procedures and emergent or urgent procedures describe the timing of a procedure when the timing is related to the patient’s condition. 

An elective procedure is typically planned in advance (eg, scheduled for weeks later), while an emergent procedure is typically performed immediately or with minimal delay to allow for patient stabilization.

Both elective and emergent procedures may be minor or major procedures.

Surgery–Risk Factors, Patient or Procedure

Risk factors are those that are relevant to the patient and procedure. Evidence-based risk calculators may be used, but are not required, in assessing patient and procedure risk.

Drug therapy requiring intensive monitoring for toxicity

A drug that requires intensive monitoring is a therapeutic agent that has the potential to cause serious morbidity or death. 

The monitoring is performed for assessment of these adverse effects and not primarily for assessment of therapeutic efficacy.

The monitoring should be that which is generally accepted practice for the agent but may be patient-specific in some cases. 

Intensive monitoring may be long-term or short-term. Long-term intensive monitoring is not performed less than quarterly. 

The monitoring may be performed with a laboratory test, a physiologic test, or imaging. Monitoring by history or examination does not qualify. 

The monitoring affects the level of MDM in an encounter in which it is considered in the management of the patient. 

Examples may include monitoring for cytopenia in the use of an antineoplastic agent between dose cycles or the short-term intensive monitoring of electrolytes and renal function in a patient who is undergoing diuresis. 

Examples of monitoring that do not qualify include monitoring glucose levels during insulin therapy, as the primary reason is the therapeutic effect (even if unless severe hypoglycemia is a current, significant concern); or annual electrolytes and renal function for a patient on a diuretic, as the frequency does not meet the threshold. 

Return to E/M Guidelines for Office/Outpatient 2021

E/M Guidelines for Office/Outpatient 2021

E/M Guidelines for Office/Outpatient History and Exam

The 2021 E&M Guidelines for Office or Other Outpatient E/M Services will help you understand the revised E/M codes.

The History and/or Examination portion of these E/M guidelines explains that office and other outpatient E/M services include “a medically appropriate history and/or physical examination, when performed.”

The “Medically appropriate” means that the physician or other qualified healthcare professional reporting the E/M determines the nature and extent of any history or exam for a particular service.

Remember that code selection does not depend on the level of history or exam.

The history and exam guidelines for office and outpatient E/M visits also specify that the “care team” may collect information, and the patient (or caregiver) may provide information, such as by portal or questionnaire. The reporting provider must then review that information.


The code selection will be either total encounter time or MDM to select the level of office or other outpatient E/M in 2021, 

In the 2021 MDM guidelines, CPT states that MDM “includes establishing diagnoses, assessing the status of a condition, and/or selecting a management option.” Three elements define MDM for office/outpatient visits in 2021, and they are similar but not identical to the 2020 elements


Table Row 1 Diagnosis


The number and complexity of the problem or problems the provider addresses during the E/M encounter.
  • In 2020, the guidelines instead referred to “the number of possible diagnoses and/or the number of management options.”

Table Row 2 Data


The amount and/or complexity of data to be reviewed and analyzed.” The 2021 guidelines list three categories for data: 
  1. Tests, documents, orders, or independent historians, 
  2. Independent test interpretation, and 
  3. Discussion of management or test interpretation with external providers or appropriate sources. 
The latter term refers to non-healthcare, non-family sources involved in patient management, like a parole officer or case manager.
  • The 2020 MDM guidelines also included the amount and/or complexity of medical records, test, and other information involved, but the 2021 guidelines expand the section significantly


Table Row 3 Risk


The risk of complications and/or morbidity or mortality of patient management decisions made at the visit.” 

The 2021 guidelines make it clear that options considered, but not selected, are still a factor for this element, specifically after “shared” MDM with the patient, family, or both. Examples include deciding against hospitalization for a psychiatric patient with sufficient support for outpatient care or choosing palliative care for a patient with advanced dementia and an acute condition.
  • The 2020 MDM guidelines included comparable wording, but they did not include the reference to shared MDM or the examples found in the 2021 guidelines.

MDM - Medical Decision Making Table

The 2021 MDM table in the CPT E/M guidelines has three main columns with the final column divided into three additional columns
  1. Code
  2. Level of MDM (Based on 2 out of 3 Elements of MDM)
  3. Elements of Medical Decision Making
    • Number and Complexity of Problems Addressed at the Encounter
    • Amount and/or Complexity of Data to be Reviewed and Analyzed
    • Risk of Complications and/or Morbidity or Mortality of Patient Management

Summary of Evaluation and Management Changes 2021

 The AMA conducted a peer-reviewed study to determine the amount of time that could be saved after CMS’ changes for E/M encounters are fully implemented. 

They found that the changes would bring a conservative reduction of 2.11 minutes per visit. Assuming a physician sees 20 patients per day, physicians would gain about 42 minutes a day to focus on patient care.

  • Reduce administrative burden on documentation and coding
  • Reduce the need for audits by adding and expanding key definitions and guidelines
  • Reduce documentation in the medical record that is not needed for patient care
  • Keep payment for E/M resource-based and eliminate the need to redistribute payments between specialties
  • Deletion of level outpatient visit CPT code 99201

Summary of Revision E&M 2021


Eliminate documentation of the history and physical exam as components for E/M code selection, however, AMA asked the providers should continue the documentation part of the history and physical exam in order to evaluate the patient's care and conditions.

Office and other outpatient services include a medically appropriate history and/or physical examination when performed. The provider determines the nature and extent of the history and/or exam required. The extent of history and exam do not affect code selection for E/M codes 99202–99215. However, all services performed should be documented appropriately in the medical record.

The physicians can select the E/M level based on the MDM or on total time.




The three elements of MDM is important to select the level
  • The complexity of the patient’s presenting problem, 
  • Data to be reviewed, 
  • Risk is not materially changed, but the work-group did extensively edit and clarify definitions in the E/M guidelines 


Time is defined as MINIMUM TIME, not typical time, and is measured as the total time the physician or other qualified healthcare professional spends on the date of service. 
  • Face-to-face and
  • Non-face-to-face time
This includes time in activities that require the physician or QHP and does not include time in activities normally performed by clinical staff.

The time calculation would be considered as physician/other qualified health care professional spends time on the day of the encounter includes the following activities when performed,
  • Preparing to see the patient (e.g., review of tests)
  • Obtaining and/or reviewing the 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 records
  • Independently interpreting results (not separately reported)  and communicating results to the patient/family/caregiver
  • Care coordination (not separately reported)

Prolonged Service

Use 99417 & G2212 in conjunction with 99205, 99215 and do not report 99417 on the same date of service as 99354, 99355, 99358, 99359, 99415, 99416

Do not report 99417 for any time unit less than 15 minutes. 

The payers will not reimburse you unless you report it with an appropriate primary code because this code is an add–on code, 

Confirm payer coverage and requirements for this code.
  • Medicare requires this code G2212 in place of +99417.
  • Private payers require this code 99417 in place of G2212
As an example of proper use, when coding based on time, you report 99205 for a new patient visit lasting 60 to 74 minutes. Once the time reaches 89 minutes, you also may report +G2212 because 89 minutes is 15 minutes beyond the maximum required time of 74 minutes.

When coding based on time, you report 99205 for a new patient visit lasting 60 to 74 minutes. Once the time reaches 75 minutes, you also may report +99417 because 75 minutes is 15 minutes beyond the minimum required time of 60 minutes.

When coding based on time, you report 99215 for an established patient visit lasting 40 to 54 minutes. Once the time reaches 55 minutes, you also may report +99417 because 75 minutes is 15 minutes beyond the minimum required time of 60 minutes.
