Warning: If You
Practice in Delaware, Maryland, Texas, Virginia, or the
District of Columbia, Your Medicare Carrier has Changned the Rules
for Quantifying Your Medical Decision Making. For details,

Quantifying Your Cognitive
Labor
This is
arguably the most important of the three key components because
the Medical Decision-Making (
MDM
)
reflects the intensity of the cognitive labor performed by the
physician. The official
rules for interpreting the
MDM
are identical for both the 1995 and 1997 E/M guidelines. There are four levels
of
MDM
of incrementally
increasing complexity:
Physicians must stratify the MDM into one of the above levels
of complexity based on:
- The nature and number of clinical problems
- The amount and complexity of the data reviewed by the
physician
- The risk of morbidity and mortality to the
patient.
The overall level of Medical Decision-Making is determined by referring to the following table: |
| Number of diagnoses or
management options
|
Amount and/or complexity
of data to be reviewed |
Risk of complications
and/or morbidity or mortality |

| Risk is determined by referring to the table
of risk which describes four levels of
medical jeopardy:
When
referring to the table, the level of risk is determined by examining
three separate dimensions of the encounter:
E/M University Coding
Tip: The E/M
guidelines explicitly state that the highest level of risk present
in any one of the above categories determines the overall risk of
the encounter. Physicians often underestimate the level of risk as defined by the E/M
guidelines.
Decision-Making Point
System
A casual review of the official rules
for interpreting the key component of Medical Decision-Making shows
that the criteria for quantifying physician cognitive labor are
quite ambiguous. Medicare discovered that auditors were having
a hard time nailing down the level of Medical Decision-Making during
the medical review process. In response to this problem, a
more objective Medical Decision-Making Point System was
developed by
CMS
. Although not part of the official
E/M guidelines, this MDM Point System was distributed to all
Medicare carriers to be used on a "voluntary" basis. In point
of fact, this is the way your Medical Decision-Making will be graded
in the event of an audit.
This approach uses a matrix of
weighted points to answer most of the questions left open by the
official E/M guidelines regarding the
MDM
. Instead of vague words like
“extensive” the
MDM
Point System
uses a numeric scale to describe the number and nature of the
diagnoses being addressed. These issues are quantified using “Problem Points”. Similarly, the extent of the
data reviewed is quantified by using “Data Points” which reflect the
volume and complexity of the information processed by the
physician. Risk is
determined by referring to the identical table of risk used by the official E/M
guidelines.
Problem Points
The “nature and number of clinical problems” are quantified
into Problem Points by referring to the following
table:
|
| Problems |
Points |
| Self-limited or minor (maximum of 2) |
1 |
| Established problem, stable or improving |
1 |
| Established problem, worsening |
2 |
| New problem, with no additional work-up planned (maximum of 1) |
3 |
| New problem, with additional work-up planned |
4 |
|
The above table is fairly self explanatory. An example of a “self-limited or minor” problem may be a common cold or an insect bite. An “established problem” refers to a diagnosis which is already known to the examiner, such as hypertension, osteoarthritis or diabetes. An example of a “new problem with no additional work-up planned” may be a new diagnosis of essential hypertension. Examples of “new problem, with additional work-up planned” may include any new clinical issue which requires further investigation such as chest pain, proteinuria, anemia, shortness of breath, etc
E/M University Coding Tip: Problems which are not being addressed specifically by the physician during the encounter may still be counted if they significantly increase the complexity of the cognitive labor required. For example, consider a patient with diabetes who is being evaluated by a vascular surgeon for a lower extremity revascularization procedure. It would be appropriate for the surgeon to include diabetes as an “established problem, stable” when calculating the problem points. This is because the comorbidity of diabetes does significantly influence the risk of the procedure and the complexity of the post operative management.
E/M University Coding Tip: Problems are defined relative to the examiner, not the patient. Even if the problem was previously known to other physicians or to the patient, it is still considered new to you if you are seeing the patient for the first time. This situation arises often in the case on consultations.
Data Points
The “amount and complexity of the data reviewed” are quantified by referring to the following table: |
|
The physician should be aware that no “double dipping” is allowed. For example, if you review lab results and order labs during the same visit, you only get one point (not one point for ordering and one point for reviewing). This same rules applies to imaging studies or other medicine tests such as EKGs or PFTs. Commonly overlooked points are those garnered for obtaining or reviewing old records. If you do review old records, you must summarize your findings in the chart. It is not acceptable to just say, “Old records were reviewed.”
E/M University Coding Tip: Notice that points can accumulate quickly if you personally review an image, tracing or specimen. You can still claim these points, even if the image, tracing or specimen has been reviewed by another physician (as when a radiologist provides an official interpretation for an X-ray). However, you must include your own interpretation in the chart in order to claim these points.
Adding it All Up: How to Calculate Your Cognitive Labor
After calculating the Problem Points and the Data Points and stratifying the level of risk, the overall complexity of MDM is determined by referring to the yet another table:
MDM Points Table
(Two out of threemust be present to qualify for a given level of MDM) |
|
Example:
Suppose you see a patient in
the office with stable diabetes and sub-optimally controlled
hypertension. After
checking routine labs, you decide to increase the patient’s
lisinopril from 10 to 20 mg po qd. If you calculate the
individual points and assign a level of risk, the MDM table for this encounter would
look like this: |
|
| Since it only takes two out of three
elements to qualify for any level of
MDM
, it is clear that this
encounter qualifies for “Moderate Complexity” medical
decision-making because of:
· Three Problem Points (one point for diabetes--
established problem, two points for hypertension—established
problem, worsening)
· One Data Point for reviewing labs
· Moderate Risk due to the management option selected of “prescription drug
management”
E/M University
Coding Tip: The MDM point system provides a
repeatable and objective way for the physician to measure the
cognitive labor required to address the clinical issues of any
encounter. Many
physicians systematically underestimate the value of their medical
decision-making. This
occurs because there is a tendency to equate “routine” thought
processes with “straightforward” medical decision-making which is
simply not true. Utilizing the objective
MDM point system can help you avoid
this self-deprecating pattern of behavior. |
