Geriatric Patients: Are They Getting the Best Prosthetic Choices?
By Raymond Francis, CP Classifying geriatric patients appropriately is
crucial to providing beneficial components.
 Most patients currently needing prosthetic care in
the United States are geriatrics. I estimate that 70 percent of the
patients seen by most practices are geriatrics, and the percentage
is probably higher in areas such as Florida where there are large
retirement communities. The prostheses for these patients are
reimbursed through Medicare, which requires that patients be
classified in one of five categories according to their POTENTIAL
of functionality.
Developed by Medicare's legal experts and endorsed by the
government with very little input from our industry, these
functional classifications contain some vague wording which could
result in a patient being placed in an inappropriate category.
Since the types of components that will be reimbursed for a
Medicare patient are dependent upon this classification, whether
the patient is classified correctly is significant. In an effort to
ensure that geriatric patients are provided with the components
they need in order to live their lives to the fullest, let's
examine each of these five categories and address areas of
concern.
The regulations require the category classification to be
determined by the prosthetist and attending physician coming to
agreement regarding the patient's potential. In most cases the
physician relies very strongly on the prosthetist's
recommendations. Often, the patient may not realize that these
professionals actually determine and establish the patient's
classification category. It is interesting to note that therapists,
both physical and occupational, as well as the social worker, case
worker, or anyone else who works with the patient, are not
considered. If the prosthetist and the physician are wise, they
will request and consider input from the therapists when making
their decision.
Category 0
Category 0 is a patient who is not a prosthetic candidate--who
usually is bedridden or has no ability to stand up. Medicare will
not reimburse for any prosthetic work done for this patient, even
if the patient has complete Medicare coverage.
Category 1
"Has the ability or potential to use a prosthesis for transfers
or ambulation on level surfaces at fixed cadence. Typical of the
limited and unlimited household ambulator."
This classification indicates that the patient has the ability
(or the POTENTIAL to have the ability) to use the prosthesis for
transfers from one place or chair to another and to walk on level
surfaces, such as floors at home at just one speed--usually very
slowly. This type of patient has typically been classified as a
"household ambulator."

This suggests strongly that the patient doesn't go
outside of the house to uneven terrain, uneven sidewalks, or
anywhere there are slopes and surface irregularities. It suggests
that people use a wheelchair for such situations and only use their
prosthesis indoors in a confined level-floor situation. People in
this category cannot be reimbursed for energy-storing feet,
hydraulic knees, or any knee system that might employ higher or
newer technology for the use of fluid control to prevent
stumbling.
It seems ironic that if the patient is classified at this time
as only having the ability to be a household ambulator, then we
will never really know if the patient has the potential to move to
the next level with the aid of more high-tech equipment.
Category 2
"Has the ability or potential for ambulation with the ability to
traverse low-level environmental barriers such as curbs, stairs, or
uneven surfaces. Typical of the limited community ambulator."
In this category, Medicare expects the patient to have the
ability, or at least the potential, to go outside into the
community and be able to handle such barriers as stepping up onto
curbs, stairs, and uneven surfaces. There are no restrictions as to
the patient using additional walking aids such as crutches, canes,
or walkers to achieve this goal. Patients are free to use any of
these as long as they can fill the requirements stated above.
Over the years I have found that prosthetists tend to quickly
classify their geriatric patients into category 1 or 2. Certainly
most geriatrics can fill the requirements of category 2, however,
many in reality could reach category 3.
Category 3
"Has the ability or potential for ambulation with variable
cadence. Typical of the community ambulator who has the ability to
traverse most environmental barriers and may have vocational,
therapeutic, or exercise activity that demands prosthetic
utilization beyond simple locomotion."
These patients have the ability or the "potential" to reach out
and achieve not only the requirements of being a community
ambulator, but also the ability to walk at a variable cadence.
Many prosthetists assume that variable cadence means running or
jogging. In this writer's humble opinion, that is not correct.
Variable cadence to me does not necessarily mean one who is
running or jogging, but rather one who can ambulate at more than
one speed. We have seen many geriatric patients who walk slowly,
but can walk much quicker if they are crossing the street and need
to get out of the way of an oncoming vehicle. Even though they may
use a cane or other assistive devices to give themselves additional
support, either physical or mental, many older patients can walk at
what they consider to be their normal speed, but when crossing a
street can vary that cadence to a higher speed for safety reasons.
To me, this is a demonstration of variable cadence.
Components that are reimbursed for Category 3 patients include
fluid-controlled knees, which easily allow for achieving variable
cadence of the knee, and energy-storing feet, which provide
additional energy to move quicker when necessary.
Potential--or Demonstration?
A perceived "Catch 22" of this category is that many
prosthetists feel that the patient must demonstrate the ability for
variable cadence prior to receiving and billing for these
components. However, it is far easier for the patient to reach this
level of activity with these components than without them.
Prosthetists commonly interpret this classification to mean that
the patient must demonstrate the ability before becoming eligible
for this additional prosthetic equipment. That is not my
interpretation of what is written in the Medicare requirements.
Once again, we seem to gloss over the word "potential" and
substitute the word "demonstrate."
My understanding after much discussion with the people at
Medicare is that the patient must have the potential to be able to
arrive at this level of ability after having used these components.
Medicare indicates that the patient should be able to demonstrate
this ability within a reasonable period of time after receiving
these components. Medicare has suggested that a "reasonable period
of time" is one year.
We in the prosthetics industry need to understand that the
patient simply has to have the potential for this category at the
time of prosthesis application. Using these components to complete
the requirement of variable cadence then makes the patient eligible
for these services.
The second part of this classification, which states that the
patient "may have vocational, therapeutic, or exercise activity
that demands prosthetic utilization beyond simple locomotion," also
merits attention. I'd like to focus on the word "may" and point out
that it is clearly not "must." Many of the geriatric patients who
are using prostheses also have some cardiac restrictions or
concerns and may have suffered a cardiopulmonary episode that
unfortunately goes along with the disease that most likely caused
the loss of the limb.
Therefore, it is not uncommon for attending physicians to
encourage the patients to continue to "exercise" and to continue
with cardiac rehabilitation. That exercise/rehabilitation often
involves walking, bicycle riding (either stationary or mobile),
golfing, bowling, and other low-stress activities in which
geriatric patients can participate. Many geriatrics may also have
part-time employment requiring they remain standing for periods of
time.
In these types of activities, we see that the geriatric patient
requires the use of energy-storing feet as well as fluid-controlled
knee stability. Patients wishing to continue with this lifestyle
greatly need these prosthetic items. In order for these components
to be reimbursed, the patients must fulfill or have the "potential"
to fulfill the requirements of this functional classification.
We in the prosthetic industry have been shortsighted and have
overlooked the words "have the potential" as well as the words "may
have the need," as clearly stated in this classification. Because
of this, many older patients are denied these services.
Prosthetists need to be aware that if these patients have the
potential to arrive at this level of activity, and if the
prescribing physicians agree, then the patients are clearly
entitled to have this equipment. It has been my experience that a
well-documented file demonstrating that the patient does have this
potential is all that Medicare requires for financial
reimbursement.
Category 4
"Has the ability or potential for prosthetic ambulation that
exceeds basic ambulation skills, exhibiting high impact, stress, or
energy levels. Typical of the prosthetic demands of the child,
active adult, or athlete."
This level is clearly outlined for the athlete. Very few older
patients fall into this category--however, there are some. Most of
these are healthy individuals who have undergone amputation at a
much younger age and have continued to be athletes. By "healthy
individuals," I mean they did not undergo amputation because of
medical reasons such as vascular disease, diabetes, or
cardiopulmonary insufficiency, but rather due to trauma. Even
though they may fall into the category of geriatric (65 years or
older), they are still quite young at heart and physically fit.
These individuals may participate in tennis, jogging, or a number
of other strenuous activities. Once again, we notice the words
"have the potential" to arrive and/or maintain this level of
athletic activity. There are very few items (mainly feet) that are
classified as Level 4. There are no knees that I am aware of in
this category.
We need to point out that an amputee at higher level--for
example a Level 4--can use anything in a Level 4, 3, 2, or 1. The
amputee is eligible for anything in his category and lower.
However, he cannot move to a higher category without first being
established as qualifying for that category.
Summary
Patients who have the potential to upgrade or improve their
activity have one year's time to achieve this. At the end of that
year, the prosthetist should document in the patient's file that
the patient is doing the activities expected and is fulfilling the
potential of the category in which he has been placed.
I feel many older amputees are not getting the type of
prosthetic devices that would benefit them the most because they
are not properly categorized. Prosthetists are afraid to reach out
and place them in a higher category, lest Medicare rebel. The
prosthetist must look at all of the potential abilities of the
patient, discuss them at length with the prescribing physician, and
come to a realistic assessment of that potential. Many older
patients can be provided with the tools to make their lives more
meaningful and enjoy some of the newer technologies now available
to the amputee community. Raymond Francis, CP, is a certified prosthetist with over 40 years experience. His patients have included amputees of all ages and activity levels ranging from older, less active amputees to active-duty military. He is the chief prosthetist for Ohio Willo
