Evaluation and Management (E&M) Guidelines
Evaluation and Management coding is a medical coding process in support of medical billing. Practicing health care providers in the United States must use E/M coding to be reimbursed by Medicare, Medicaid programs, or private insurance for patient encounters.
E/M standards and guidelines were established by Congress in 1995 and revised in 1997. It has been adopted by private health insurance companies as the standard guidelines for determining type and severity of patient conditions. This allows medical service providers to document and bill for reimbursement for services provided.
1995 Documentation Guidelines
For Evaluation and Management Services
WHAT IS DOCUMENTATION AND WHY IS IT IMPORTANT?
Medical record documentation is required to record pertinent facts, findings, and observations about an individual's health history including past and present illnesses, examinations, tests, treatments, and outcomes. The medical record chronologically documents the care of the patient and is an important element contributing to high-quality care. The medical record facilitates:
- the ability of the physician and other healthcare professionals to evaluate and plan the patient’s immediate treatment, and to monitor his/her healthcare over time;
- communication and continuity of care among physicians and other healthcare professionals involved in the patient's care;
- accurate and timely claims review and payment;
- appropriate utilization review and quality of care evaluations; and
- collection of data that may be useful for research and education.
An appropriately documented medical record can reduce many of the "hassles" associated with claims processing and may serve as a legal document to verify the care provided, if necessary.
WHAT DO PAYERS WANT AND WHY?
Because payers have a contractual obligation to enrollees, they may require reasonable documentation that services are consistent with the insurance coverage provided. They may request information to validate:
- the site of service;
- the medical necessity and appropriateness of the diagnostic and/or therapeutic services provided; and/or
- that services provided have been accurately reported.
II. GENERAL PRINCIPLES OF MEDICAL RECORD DOCUMENTATION
The principles of documentation listed below are applicable to all types of medical and surgical services in all settings. For Evaluation and Management (E/M) services, the nature and amount of physician work and documentation varies by type of service, place of service and the patient's status. The general principles listed below may be modified to account for these variable circumstances in providing E/M services.
1. The medical record should be complete and legible.
2. The documentation of each patient encounter should include:
- reason for the encounter and relevant history, physical examination findings, and prior diagnostic test results;
- assessment, clinical impression, or diagnosis;
- plan for care; and
- date and legible identity of the observer.
3. If not documented, the rationale for ordering diagnostic and other ancillary services should be easily inferred.
4. Past and present diagnoses should be accessible to the treating and/or consulting physician.
5. Appropriate health risk
6. The patient's progress, response to and changes in treatment, and revision of diagnosis should be documented.
7. The CPT and ICD-9-CM codes reported on the health insurance claim form or billing statement should be supported by the documentation in the medical record.
II. DOCUMENTATION OF E/M SERVICES
This publication provides definitions and documentation guidelines for the three key components of E/M services and for visits which consist predominately of counseling or coordination of care. The three key components--history, examination, and medical decision making--appear in the descriptors for office and other outpatient services, hospital observation services, hospital inpatient services, consultations, emergency department services, nursing facility services, domiciliary care services, and home services. While some of the text of CPT has been repeated in this publication, the reader should refer to CPT for the complete descriptors for E/M services and instructions for selecting a level of service. Documentation guidelines are identified by the symbol • DG.
The descriptors for the levels of E/M services recognize seven components which are used in defining the levels of E/M services. These components are:
- medical decision making;
- coordination of care;
- nature of presenting problem; and
The first three of these components (i.e., history, examination and medical decision making) are the key components in selecting the level of E/M services. An exception to this rule is the case of visits which consist predominantly of counseling or coordination of care; for these services time is the key or controlling factor to qualify for a particular level of E/M service.
For certain groups of patients, the recorded information may vary slightly from that described here. Specifically, the medical records of infants, children, adolescents and pregnant women may have additional or modified information recorded in each history and examination area.
As an example, newborn records may include under history of the present illness (HPI) the details of mother’s pregnancy and the infant's status at birth; social history will focus on family structure; family history will focus on congenital anomalies and hereditary disorders in the family. In addition, information on growth and development and/or nutrition will be recorded. Although not specifically defined in these documentation guidelines, these patient group variations on history and examination are appropriate.
A. DOCUMENTATION OF HISTORY
The levels of E/M services are based on four types of history (Problem Focused, Expanded Problem Focused, Detailed, and Comprehensive). Each type of history includes some or all of the following elements:
- Chief complaint (CC);
- History of present illness (HPI);
- Review of systems (ROS); and
- Past, family and/or social history (PFSH).
The extent of history of present illness, review of systems, and past, family and/or social history that is obtained and documented is dependent upon clinical judgment and the nature of the presenting problem(s).
The chart below shows the progression of the elements required for each type of history. To qualify for a given type of history, all three elements in the table must be met. (A chief complaint is indicated at all levels.)
Present Illness (HPI)
Review of Systems (ROS)
and/or Social History (PFSH)
Type of History
- DG: The CC, ROS and PFSH may be listed as separate elements of history, or they may be included in the description of the history of the present illness.
o describing any new ROS and/or PFSH information or noting there has been no change in the information; and
o noting the date and location of the earlier ROS and/or PFSH.
Definitions and specific documentation guidelines for each of the elements of history are listed below.
CHIEF COMPLAINT (CC)
The CC is a concise statement describing the symptom, problem, condition, diagnosis, physician recommended return, or other factor that is the reason for the encounter.
HISTORY OF PRESENT ILLNESS (HPI)
The HPI is a chronological description of the development of the patient's present illness from the first sign and/or symptom or from the previous encounter to the present. It includes the following elements:
Brief and extended HPIs are distinguished by the amount of detail needed to accurately characterize the clinical problem(s).
A brief HPI consists of one to three elements of the HPI.
An extended HPI consists of four or more elements of the HPI.
REVIEW OF SYSTEMS (ROS)
A ROS is an inventory of body systems obtained through a series of questions seeking to identify signs and/or symptoms which the patient may be experiencing or has experienced.
For purposes of ROS, the following systems are recognized:
A problem pertinent ROS inquires about the system directly related to the problem(s) identified in the HPI.
An extended ROS inquires about the system directly related to the problem(s) identified in the HPI and a limited number of additional systems.
A complete ROS inquires about the system(s) directly related to the problem(s) identified in the HPI plus all additional body systems.
PAST, FAMILY, AND/OR SOCIAL HISTORY (PFSH)
The PFSH consists of a review of three areas:
For the categories of subsequent hospital care, follow-up inpatient consultations and subsequent nursing facility care, CPT requires only an "interval" history. It is not necessary to record information about the PFSH.
A pertinent PFSH is a review of the history area(s) directly related to the problem(s) identified in the HPI.
A complete PFSH is of a review of two or all three of the PFSH history areas, depending on the category of the E/M service. A review of all three history areas is required for services that by their nature include a comprehensive assessment or reassessment of the patient. A review of two of the three history areas is sufficient for other services.
B. DOCUMENTATION OF EXAMINATION
The levels of E/M services are based on four types of examination that are defined as follows:
For purposes of examination, the following body areas are recognized:
For purposes of examination, the following organ systems are recognized:
The extent of examinations performed and documented is dependent upon clinical judgment and the nature of the presenting problem(s). They range from limited examinations of single body areas to general multi-system or complete single organ system examinations.
C. DOCUMENTATION OF THE COMPLEXITY OF MEDICAL DECISION MAKING
The levels of E/M services recognize four types of medical decision making (straight-forward, low complexity, moderate complexity, and high complexity). Medical decision making refers to the complexity of establishing a diagnosis and/or selecting a management option as measured by:
The chart below shows the progression of the elements required for each level of medical decision making. To qualify for a given type of decision making, two of the three elements in the table must be either met or exceeded.
Number of diagnoses or management options
Amount and/or complexity of data to be reviewed
Risk of complications and/or morbidity or mortality
Type of decision making
Minimal or None
Each of the elements of medical decision making is described on the following page.
NUMBER OF DIAGNOSES OR MANAGEMENT OPTIONS
The number of possible diagnoses and/or the number of management options that must be considered is based on the number and types of problems addressed during the encounter, the complexity of establishing a diagnosis and the management decisions that are made by the physician.
Generally, decision making with respect to a diagnosed problem is easier than that for an identified but undiagnosed problem. The number and type of diagnostic tests employed may be an indicator of the number of possible diagnoses. Problems which are improving or resolving are less complex than those which are worsening or failing to change as expected. The need to seek advice from others is another indicator of complexity of diagnostic or management problems.
- For a presenting problem with an established diagnosis the record should reflect whether the problem is: a) improved, well controlled, resolving or resolved; or, b) inadequately controlled, worsening, or failing to change as expected.
- For a presenting problem without an established diagnosis, the assessment or clinical impression may be stated in the form of a differential diagnoses or as "possible,” "probable,” or "rule out” (R/O) diagnoses.
AMOUNT AND/OR COMPLEXITY OF DATA TO BE REVIEWED
The amount and complexity of data to be reviewed is based on the types of diagnostic testing ordered or reviewed. A decision to obtain and review old medical records and/or obtain history from sources other than the patient increases the amount and complexity of data to be reviewed.
Discussion of contradictory or unexpected test results with the physician who performed or interpreted the test is an indication of the complexity of data being reviewed. On occasion the physician who ordered a test may personally review the image, tracing or specimen to supplement information from the physician who prepared the test report or interpretation; this is another indication of the complexity of data being reviewed.
RISK OF SIGNIFICANT COMPLICATIONS, MORBIDITY, AND/OR MORTALITY
The risk of significant complications, morbidity, and/or mortality is based on the risks associated with the presenting problem(s), the diagnostic procedure(s), and the possible management options.
The following table may be used to help determine whether the risk of significant complications, morbidity, and/or mortality is minimal, low, moderate, or high. Because the determination of risk is complex and not readily quantifiable, the table includes common clinical examples rather than absolute measures of risk. The assessment of risk of the presenting problem(s) is based on the risk related to the disease process anticipated between the present encounter and the next one. The assessment of risk of selecting diagnostic procedures and management options is based on the risk during and immediately following any procedures or treatment. The highest level of risk in any one category (presenting problem(s), diagnostic procedure(s), or management options) determines the overall risk.

D. DOCUMENTATION OF AN ENCOUNTER DOMINATED BY COUNSELING OR COORDINATION OF CARE
In the case where counseling and/or coordination of care dominates (more than 50%) of the physician/patient and/or family encounter (face-to-face time in the office or other outpatient setting or floor/unit time in the hospital or nursing facility), time is considered the key or controlling factor to qualify for a particular level of E/M services.
- DG: A ROS and/or a PFSH obtained during an earlier encounter does not need to be re-recorded if there is evidence that the physician reviewed and updated the previous information. This may occur when a physician updates his/her own record or in an institutional setting or group practice where many physicians use a common record. The review and update may be documented by:
- DG: The ROS and/or PFSH may be recorded by ancillary staff or on a form completed by the patient. To document that the physician reviewed the information, there must be a notation supplementing or confirming the information recorded by others.
- DG: If the physician is unable to obtain a history from the patient or other source, the record should describe the patient's condition or other circumstance which precludes obtaining a history.
- DG: The medical record should clearly reflect the chief complaint.
- modifying factors; and
- associated signs and symptoms.
- DG: The medical record should describe one to three elements of the present illness (HPI).
- DG: The medical record should describe four or more elements of the present illness (HPI) or associated comorbidities.
- Constitutional symptoms (e.g., fever, weight loss)
- Ears, Nose, Mouth, Throat
- Integumentary (skin and/or breast)
- DG: The patient's positive responses and pertinent negatives for the system related to the problem should be documented.
- DG: The patient's positive responses and pertinent negatives for two to nine systems should be documented.
- DG: At least ten organ systems must be reviewed. Those systems with positive or pertinent negative responses must be individually documented. For the remaining systems, a notation indicating all other systems are negative is permissible. In the absence of such a notation, at least ten systems must be individually documented.
- past history (the patient's past experiences with illnesses, operations, injuries and treatments);
- family history (a review of medical events in the patient's family, including diseases which may be hereditary or place the patient at risk); and
- social history (an age appropriate review of past and current activities).
- DG: At least one specific item from any of the three history areas must be documented for a pertinent PFSH.
- DG: At least one specific item from two of the three history areas must be documented for a complete PFSH for the following categories of E/M services: office or other outpatient services, established patient; emergency department; subsequent nursing facility care; domiciliary care, established patient; and home care, established patient.
- DG: At least one specific item from each of the three history areas must be documented for a complete PFSH for the following categories of E/M services: office or other outpatient services, new patient; hospital observation services; hospital inpatient services, initial care; consultations; comprehensive nursing facility assessments; domiciliary care, new patient; and homecare, new patient.
- Problem Focused -- a limited examination of the affected body area or organ system.
- Expanded Problem Focused -- a limited examination of the affected body area or organ system and other symptomatic or related organ system(s).

- DG: Abnormal or unexpected findings of the examination of the unaffected or asymptomatic body area(s) or organ system(s) should be described.
- DG: A brief statement or notation indicating "negative" or "normal" is sufficient to document normal findings related to unaffected area(s) or asymptomatic organ system(s).
- DG: The medical record for a general multi-system examination should include findings about 8 or more of the 12 organ systems.
- the number of possible diagnoses and/or the number of management options that must be considered;
- the amount and/or complexity of medical records, diagnostic tests, and/or other information that must be obtained, reviewed, and analyzed; and
- the risk of significant complications, morbidity, and/or mortality, as well as comorbidities associated with the patient's presenting problem(s), the diagnostic procedure(s) and/or the possible management options.
- DG: For each encounter, an assessment, clinical impression, or diagnosis should be documented. It may be explicitly stated or implied in documented decisions regarding management plans and/or further evaluation.
- DG: The initiation of, or changes in, treatment should be documented. Treatment includes a wide range of management options including patient instructions, nursing instructions, therapies, and medications.

- DG: The review of lab, radiology and/or other diagnostic tests should be documented. An entry in a progress note such as "WBC elevated" or "chest x-ray unremarkable" is acceptable. Alternatively, the review may be documented by initialing and dating the report containing the test results.
- DG: A decision to obtain old records or decision to obtain additional history from the family, caretaker or other source to supplement that obtained from the patient should be documented.
- DG: Relevant finding from the review of old records, and/or the receipt of additional history from the family, caretaker or other source should be documented. If there is no relevant information beyond that already obtained, that fact should be documented. A notation of "Old records reviewed” or "additional history obtained from family” without elaboration is insufficient.
- DG: The results of discussion of laboratory, radiology or other diagnostic tests with the physician who performed or interpreted the study should be documented.
- DG: The direct visualization and independent interpretation of an image, tracing, or specimen previously or subsequently interpreted by another physician should be documented.
- DG: Comorbidities/underlying diseases or other factors that increase the complexity of medical decision making by increasing the risk of complications, morbidity, and/or mortality should be documented.
- DG: If a surgical or invasive diagnostic procedure is ordered, planned, or scheduled at the time of the E/M encounter, the type of procedure eg, laparoscopy, should be documented.
- DG: If a surgical or invasive diagnostic procedure is performed at the time of the E/M encounter, the specific procedure should be documented.
- DG: The referral for or decision to perform a surgical or invasive diagnostic procedure on an urgent basis should be documented or implied.
- DG: If the physician elects to report the level of service based on counseling and/or coordination of care, the total length of time of the encounter (face-to-face or floor time, as appropriate) should be documented and the record should describe the counseling and/or activities to coordinate care.
