Introduction to Medical
Systems
Home
The Systems Explorer (SE) has been created as a means of
introducing the disability representative to some of the more common
physical and mental limitations that can be caused by a given disease
state. This new CD version will be especially helpful to those who do not have formal training in a health-related
field.
In the Systems Explorer, we provide a unique
perspective on medical conditions and how they are used within the
Social Security disability process. The SE is designed to be
used with our Social Security Guide. Together, the Systems
Explorer and the Social Security Guide will provide you with a
detailed perspective on how medical conditions are perceived by Social
Security.
The older versions of our Systems Explorer
focused on specific medical conditions. With the incorporation of the
Social Security Guide into our program, this approach is no longer
necessary. The Social Security Guide provides an impressive
discussion of each disease category and the appropriate medical
listings for that disease.
The Systems Explorer is divided into what is
known as systems categories. A systems category is simply a
collection of diseases that fall within a related category of
disease. In this new version of the SE, we will focus on how a
particular category of disease might restrict a person's ability to
perform work. This means that instead of trying to define limitations
for each and every disease within a category, we'll focus on the
category itself. We'll discuss how many diseases within a particular
category can affect an individual's physical and/or mental
capabilities.
Each disease category within the SE has a list
of common diagnoses associated with it. This list of common disorders
will give you some idea of the types of diseases that fall within a
given category. You'll also find a narrative discussion of common
physical and mental limitations that are caused by diseases within a
particular category. We'll point out supportive evidence commonly
used in the evaluation of certain disease states and methods used to
prove symptom severity. We'll also discuss special disease
characteristics as they pertain to Social Security disability.
Be aware that not all symptoms or limitations
commonly found within a disease category will occur in every case.
You must review each case individually and use your knowledge and
common sense to extract what is specific to that client's case. If
the claimant alleges a given restriction, you cannot take him at his
word. You must prove that the symptom exists via the client's medical
documentation. The client's symptoms must have a loose nexus before
they can be used to support a limitation. That is, the symptom must
be related to the disease being alleged by the claimant.
As the claimant's representative, it is your
job to identify as many symptoms as possible and use those symptoms in
your argument for physical or mental limitation. Most claimants never
express the full restrictive nature of their impairments. Therefore,
it is up to you to make sure that all reasonable symptoms and there
restrictions are considered. A reasonable restriction is any physical
or mental limitation that is supported by the medical evidence.
Identifying and learning about a disease
Let’ss say that you have just opened your first
case and the disease the claimant is alleging is called a CVA or
Cerebrovascular Accident (Stroke). You have never taken a medical
terminology course and you have no idea what a CVA is. What do you
do?
We recommend you use the Merck Manual to learn
about any disease you'll encounter as a disability advocate. You can
purchase a Merck Manual or use the online link from the Advocate
Client Manager software. When using the Merck Manual, you need only
to turn to the rear of the text and look up in alphabetical order the
terms Cerebrovascular Accident. The manual will give you a page
number where the disease is discussed. Turn to that page for a
complete discussion of the disease.
In the Merck Manual, a CVA could be listed
under several disease categories. The reason for this is because a
CVA has both circulatory and neurological implications. This is true
of many diseases so don't let this fact confuse you. Even though the
Merck Manual discussion can be a bit technical, you'll learn valuable
information about any disease you'll encounter as a representative.
The key to winning disability cases does not
lie in understanding the technical aspects of a disorder. Winning
disability cases is determined by how well you understand how a
particular disease can limit an individual. Learn just enough
about the disease state to unable you to argue with conviction the
limitations caused by the impairment.
What is a symptoms category?
In medical science, the human body is divided
into what is known as body systems. Each system represents a major
physiological function within the living organism. For example, the
heart is the primary organ within a major system known as the
circulatory system. The brain is the primary organ within the
neurological system, and so on.
We have chosen to focus on symptoms of a
disease because symptoms are readily apparent and easy to understand.
Documented symptoms are also the primary tool used by Social Security
in determining a claimant's physical and/or mental Residual Function
Capacity. It is far more accurate and easier to identify restrictions
based on the symptoms of a specific disease.
Body Systems or Disease Categories
For the purpose of representation, a body
system and a disease category are the same thing. A body system like
the heart will fall into the disease category for cardiovascular or
(heart disease). Assuming that you are not familiar with the commonly
used body systems, we have listed them below:
Musculoskeletal (Muscle and bone disease)
Special Senses and Speech (Sight, speech, hearing and balance)
Respiratory (Lung disease)
Cardiovascular (Heart disease)
Digestive (Diseases of the gastrointestinal track)
Genitourinary (Disease of the sex organs or bladder)
Hemolytic and Lymphatic (Blood disorders)
Skin disease (Disorders of the skin)
Hormonal (Disorders of the endocrine system)
Multiple Body Systems (Birth defects and other catastrophic
abnormalities)
Immune system disease (Disorders of the immune system like HIV)
Neurological (Disease of the brain and nerve complex)
Mental (Disorders of the mind - thinking or behavioral disorders)
Neoplastic (cancers)
Supportive
Evidence
The SE will list the types of supportive
evidence you should seek when trying to evaluate a given disease
state. Generally, medical evidence, with the possible exception of
diagnostic tests, is written in lay terms. You'll be able to
understand most of what you are reading even if you are not familiar
with medical terminology. We'll attempt to explain some of the more
common diagnostic procedures to enable you to review evidence more
confidently.
Child Cases and Age-Related
Activities
See chapter eight in
the Social Security Guide for a presentation on childhood claims.
When evaluating cases involving children,
you'll discover that there are no work issues to consider. This means
that when you argue child cases, you cannot use vocational factors as
is used in adult cases. In a child disability case (under age
eighteen), you must try to prove that as a result of the impairment,
the child cannot perform age-related activities. In a child
case, determining age-related capability is straight-forward. For
example, if a child is eight years old and is unable to dress himself
as a result of his impairment, chances are this child is suffering
from a severely disabling condition.
In a childhood claim, if a condition does not
meet or equal the medical listings, it may still be allowed based on
the child's inability to perform normal age-related activities. The
activity itself can be anything that is age related and severely
limits the normal function of the child.
The following is a list of childhood
restrictions that are considered important in the eyes of the Social
Security Administration. Look for these types of restrictions in all
cases you review:
1. Severely restricted fine or gross motor
movement of the hands.
2. Significantly reduced coordination.
3. Limitation in movement of two or more joints.
4. Severe gait disturbance (walking problems).
5. Inability to perform age-related hygiene tasks.
6. Inability to avoid environmental hazards.
7. Significantly reduced ability to communicate in speech or manner.
8. Uncontrollable antisocial behavior.
9. Uncontrollable phobias. (fears).
10. Chronic and/or severe psychological disorientation.
The foregoing symptoms are just a few of the
many restrictions that can occur as a result of an impairment. Again,
these restrictions must be age appropriate and supported by the
claimant's medical documentation. Child cases are the only cases that
use age-appropriate restrictions as the primary means of determining
disability. This is because kids don't usually have a work history so
vocational analysis would make no sense. Therefore, if you are
dealing with a case on an individual under age eighteen, focus on how
the child's impairment restricts normal age-related activities or
behaviors.
Widower Cases
A Widower case is from the standpoint of a
representative no different from any other SSDI claim. However, the
pre-application criteria to qualify for a Wisower case is slightly
different.
See Social Security
Guide, chapter two.
Let’s assume that we have a case on a 51
year-old widow who has been previously denied benefits because she
does not meet or equal the listings. Social Security regulations
allow us to review widow cases in the same way that all other adult
cases are reviewed. In other words, we must consider the widow's
remaining ability to perform work. In this example, the widow's only
impairment is morbid obesity with a weight of 320 lbs at 5'3" inches
in height. She complains of joint pain and difficulty walking.
Because she does not have an additional significant impairment, she
would not meet the medical listing criteria for obesity.
To win this case, you could attempt to prove
via the medical evidence that this claimant cannot ambulate (walk) for
more than a few minutes due to her weight and severe joint pain. It
is quite reasonable to argue this point because joint pain is common
with morbid obesity. However, for the joint pain argument to be
accepted by SSA, there must be physical evidence and X-ray findings
that show a relationship between the joint pain and a disease state
within the painful joint. In other words, the obese client must also
have evidence of at least mild arthritis of the weight bearing joint.
The claimant is the best source for these
additional allegations in cases where a single impairment is not
severe enough for an allowance. By paying close attention to the
claimant's symptoms and allegations, you can identify a multitude of
physical or mental restrictions.
Genuine symptoms will often lead to the
discovery of less serious disease state that cause additional physical
limitations. These additional disorders can then be used to further
restrict the claimant's Residual Functional Capacity, perhaps leading
to an allowance determination. In this example, obesity with joint
pain as a result of even mild arthritis could lead to an allowance
determination.
The Symptom of Pain
Pain is the most valuable and subjective
symptom in your arsenal of limiting factors. When pain is alleged,
use it to your client's advantage. First, make sure the alleged pain
has a loose nexus. That is, the pain is reasonably related to the
primary diagnosis being alleged by the claimant. The loose nexus is
determined by the findings within the claimant's medical evidence.
Once you establish a loose nexus for the pain,
establish how the pain limits the claimant's ability to perform
certain activities required in performing work. Always make sure that
the claimant's alleged pain is being caused by a medically documented
impairment. Don't just say the claimant is in pain and leave it at
that. Discuss the reason for the pain, the evidence supporting the
pain, where it is located, the efforts made to reduce it and most
importantly, how it affects the claimant's ability to perform work.
Contra-lateral Impairments
A contra-lateral impairment is a condition
whereby a claimant has a similar impairment in two locations on the
opposite side of the body. An example of a contra-lateral impairment
would be a claimant who has a club right foot on the right side and a
deformity with missing fingers of the left hand.
If the person suffering from a contra-lateral
impairment is reasonably functional despite the impairments, the case
may be denied. You must argue that due to the claimant's
contra-lateral limitations, he cannot realistically find or engage in
gainful employment. You would of course detail the limitations in
activity and movement caused by the impairments using the medical
evidence and your common sense. It doesn't take much medical
knowledge to explain how this type of condition can prevent the
performance of work.
Multiple
Impairments
In a multiple impairment condition, you are
working with a claimant who is suffering from a number of serious
medical disorders. This circumstance usually involves three or four
different disease states all of which limit the claimant's functional
capabilities. Multiple impairments are common. However, you must
learn to distinguish among those that will result in meaningful
limitations in order to win the case. A meaningful impairment is any
disorder that is moderate to severe in nature and causes a significant
physical or mental limitation.
A rule of thumb for determining which
impairments cause meaningful restrictions is to choose those
conditions that are the most serious. Serious disorders are usually
most limiting in there effect on the claimant's ability to perform
work. You can also combine severe physical and mental impairments and
show how the combination results in an inability to work. Whatever it
takes to formulate the strongest argument on behalf of your client is
the best approach. A claimant who has multiple impairments, more than
one disease state, can be restricted whether the impairments are
unilateral or contra-lateral in nature.
Requirements for Less
Than Sedentary
RFC
As you begin your career as a disability
advocate, you'll discover that the majority of your clients will be
younger individuals. That is, most claimants will be forty-nine years
of age or younger. Because of the claimant's young age category,
you'll usually be required to lower their Residual Functional Capacity
(RFC) to less than sedentary work in order to win the case.
Therefore, it is especially important that you are aware of the
requirements for a less than sedentary Residual Functional Capacity.
The requirements for less than sedentary work
are met if you determine that your client is unable to lift 10lbs
maximum and is unable to stand or walk for more than 20 minutes
without changing position or causing painful aggravation to his
condition. The following list is also used to limit a claimant to
less than sedentary work:
The individual requires a cane, walker or other
device in order to ambulate (walk).
The individual cannot bend at the waist without significant pain
or discomfort.
The individual cannot do prolonged sitting ( more than fifteen to
twenty minutes) without experiencing pain which requires frequent
postural changes for relief.
The claimant must have full use of his/her upper extremities in
order to perform sedentary work. The RFC would be limited to less
than sedentary work if the claimant is limited in fine motor movements
such as handling, fingering or feeling in either hand. The RFC is
also reduced if the claimant is unable to use or has a significant
reduction in the use of an upper limb due to any impairment.
Poor close vision: An inability or significant reduction in the
claimant's ability to read due to poor vision. This determination is
made with consideration of best corrected vision. In other words,
evaluate the claimant's vision problem with his glasses on.
Significant hearing loss: Most sedentary jobs do not require that
a person be able to hear at a normal conversational speech. Therefore,
this is useful only if hearing is required for safety or performance
of the job.
Mental Disorders
Less Than
Simple Unskilled Work:
Less than simple unskilled work is the mental
impairment equivalent of less than sedentary work. The terms simple
and unskilled are indications of the mental capacities required to
perform a given type of work. When you see these RFC terms in a
disability case, they are referring to the claimant's remaining mental
capabilities.
An individual is limited to less than "simple
unskilled" work if due to his impairment, the claimant is unable to
understand and remember very short and simple instructions. The
claimant must also be unable to carry out those simple instructions
without special supervision.
If an individual is markedly restricted in the
performance of simple unskilled work, that person cannot be reasonably
expected to perform any type of work. Social Security cannot deny a
claimant to a workshop job or work under special conditions. If the
claimant is only moderately restricted in his ability to understand,
remember and carry out simple instructions, we may want to identify
other moderate mental or physical limitations to further reduce his
Residual Functional Capacity.
Marked
vs. Moderate
Restrictions:
Using the medical evidence, you'll be able to
determine whether a claimant is moderately or markedly limited by the
impairment. All mental case evidence will contain descriptions of the
claimant's functional level during the period he/she was suffering
from the impairment. Using your common sense and noting how
claimant's symptoms are described by the evidence, you'll get a feel
for the intensity of the claimant's restrictions.
Objective
Substantive Evidence
Objective medical evidence is any medical
finding that can be observed and reproduced. This form of evidence is
the most relevant to any disability case. This type of evidence is
usually created by independent medical sources and is therefore
considered to be substantive to a case.
Examples of objective substantive evidence are
results of a doctor's physical examinations, laboratory tests, x-ray
findings, scans, biopsies, EKGs, etc. Always try to find as much
substantive evidence as possible to support your case argument. The
more objective evidence you have to support your position, the more
likely it is that Social Security will accept the premise of your
argument.
Subjective
Substantive Evidence
Subjective evidence is defined as any finding
that may or may not be reproducible and is dependent upon feedback
from the claimant or other non-medical sources. All symptoms alleged
by a claimant are considered subjective evidence. In other words,
this evidence is what the claimant or family member alleges, not
necessarily what the evidence shows. Always try to support the
claimant's subjective allegations with some form of objective
evidence. If you don't, SSA will simply ignore the allegation. Even
the allegation of pain must be substantiated with some type of
objective findings denoting the existence of an impairment that would
cause the alleged pain.
Medication Side Effects
Very often, you'll argue a case on an
individual who is under current therapy. If this therapy involves
large doses of pain medication or other drugs that alter the
claimant's mental or physical state, this finding is relevant to
determining the claimant's RFC.
If the claimant is under treatment with a drug
that causes serious adverse side-effects of any type, use this as an
additional restrictive factor in your argument for a reduced RFC.
Point out how the drug affects the claimant and describe the
limitations induced by the medications. If the claimant must be on
medication to control the disease or survive, you may win the case
based on this approach.
