on Questions for Answer:
1.
How does NCV/EMG increase Personal Injury Attorney Referrals?
o NCV/EMG findings increase the case values
o NCV/EMG objective findings support your attorney to win the
cases
o Easy and good quality note
o Higher impairment rating increase PI attorney's compensation
o
Achieving competitive advantage strengthen your business better by
providing NCV/EMG over your competitor.

2. Why
NCV/EMG should be done?
o AMA, Guides to the evaluation of permanent impairment, 6th
edition:
-
The diagnosis of a focal neuropathy syndrome must be documented
by sensory and motor nerve conduction studies (NCV) and/or needle
EMG in order to be ratable as impairment.
-
At Present, only the needle EMG is considered diagnostic of
radiculopathy.
o NCV/EMG Evidence can add 9% whole body impairment rating on
top of the residual impairment rating.
o All extremity tingling/numbness can yield Positive NCV
findings coupled with EMG finding.

3. Who need
NCV/EMG Studies?
o All patients have the following symptoms: Radiating pain,
Tingling, Numbness, Muscle weakness, etc.
o Nerve conduction velocity (NCV) studies may be indicated for
the following conditions:
-
Focal neuropathies or compressive lesions, for localization.
-
Traumatic nerve lesions, for diagnosis and prognosis.
-
Diagnosis or confirmation of suspected generalized neuropathies,
such as diabetic, uremic, metabolic, or immune.
-
Repetitive nerve stimulation in diagnosis of neuromuscular
junction disorders such as myasthenia gravis, myasthenic syndrome.
-
Differential diagnosis of symptom-based complaints (e.g., pain in
limb, weakness, disturbance in skin sensation or paresthesia)
provided the clinical assessment supports the need for a study.
o Document patient's radiculopathy or entrapment for PI claim
o Assess patient's permanent nerve damages after 6 weeks
injuries

4. Why
do you need on-site NCV/EMG ?
o Convenient service for you
-
All on-site NCV/EMG studies should be performed at your clinic.
-
We are bringing comprehensive e NCV/EMG studies to your clinic.
o Safe, Comfortable and Convenient for your patients
-
Patients benefit from on-site testing performed at your clinic.
o Avoid the fraudulent relationships or insurance fraud by
using a sub-contractor.
- Electrodiagnostic studies (NCV/EMG)
should be performed only by a license physician qualified by
reason of education, training and experience in these procedures.
Typically, these studies are performed by board-certified
neurologists and physical medicine (AMA, Guides to the evaluation
of permanent impairment, 6th edition)
o We bill patient's insurance directly.
-
We will not hold doctors liable for the unpaid bill.

5.
Why do Doctors need NCV/EMG studies?
o Document and maximize impairments ratings for your PI
attorney and
stimulate PI Referrals from attorneys.
o PI Attorneys likes the impairment ratings on your report
o An EMG is often performed when patients have unexplained
muscle weakness. The EMG helps to distinguish between muscle
conditions in which the problem begins in the muscle and muscle
weakness due to nerve disorders. The EMG can also be used to
detect true weakness, as opposed to weakness from reduced use
because of pain or lack of motivation. EMGs can also be used to
isolate the level of nerve irritation or injury.

6.
Why do PI Attorneys need NCV/EMG studies?
o PI Impairment rating can start with additional 9% plus
residual impairment rating.
o Maximize PI Attorney's compensation
o Win the PI cases with NCV/EMG objective findings.

7.
How much does it cost?
o It does not cost to you. We bill patient's insurance
directly. We will not hold doctors liable for the unpaid bill.
o Sensory or motor study per one nerve cost $95-$125
o EMG per one extremity cost $350.00

8.
How long does it take to come?
o We stop by at your office mostly within 3 days, or no more
than a week.
o Appointment date and time is mostly depending on patient's
schedule.

9.
How long does it take for studies?
o UE and LE NCV can be done about an hour.
o One Extremity EMG can be done within an hour.
o Total hour for studies depends how severe the injuries, how
many extremities to study and how many muscle to study.
o Most of studies can be done about an hour. Some studies take
3-4 hours in worst case with severe bilaterally symptoms.

10.
How to do NCV?
o During the nerve conduction study, mild electrical impulses
are sent along the course of a nerve in the arm or leg. The
electrical impulse will make the muscles in your arm and leg
contract.
o Two electrodes are placed along the course of the nerve. When
the nerve is stimulated, it must transmit the signal along its
course. The electrodes record the signal as it passes by. A normal
nerve will transmit the signal faster and stronger than a damaged
nerve.

11.
How to do EMG?
o The needle EMG study involves the insertion of needle
electrode into the skin. The electrode is moved around slightly
after its insertion. The needle electrodes are designed for
minimal pain and discomfort.
o The EMG electrodes record the electrical signal generated by
the muscle. If there is muscles disease or nerve damage, the EMG
electrode will show the abnormality.
o There is some discomfort at the time the needle electrodes
are inserted. They feel like shots. After study done, the muscle
may feel a little sore for up to a few days.

12.
What is NCV?
o NCV stands for
nerve
conduction velocity. NCV studies are used to calculate
the speed of nerve conduction velocity. A decreased speed of
transmission indicates nerve damage.
o The NCV test can be used to detect nerve damage such as
neuropathy
and
carpal
tunnel syndrome due to the entrapment, spinal disc
herniation or radiation, diabetic etc,

13.
What is EMG?
o An electromyogram (EMG) is a test that is used to record the
electrical activity of muscles. When muscles are active, they
produce an electrical current. This current is usually
proportional to the level of the muscle activity.
o EMGs can be used to detect abnormal electrical activity of
muscle that can occur in many diseases and conditions, including
muscular dystrophy, inflammation of muscles, pinched nerves,
peripheral nerve damage (damage to nerves in the arms and legs),
amyotrophic
lateral sclerosis (ALS),
myasthenia
gravis,
disc
herniation, and others.

14.
Does NCV/EMG study hurt?
o Yes, there is some discomfort at the time the needle
electrodes are inserted. They feel like shots (intramuscular
injections), although nothing is injected during an EMG. After
studies, the muscle may feel a little sore for up to a few days.
o The test is not invasive, but can be a little
painful
due to the
electrical
shocks. The shocks are associated with a low amount of
electrical
current so they are not dangerous to any patient.

15.
Who can perform NCV/EMG?
o Electrodiagnostic studies (NCV/EMG) should be performed only
by a license physician qualified by reason of education, training
and experience in these procedures. Typically, these studies are
performed by board-certified neurologists and physical medicine
(AMA, Guides to the evaluation of permanent impairment, 6th
edition)

16.
Who pay for NCV/EMG studies?
o We bill patient's insurance directly. Insurance company pay
for NCV/EMG Studies:
-
We will not hold doctors liable for the unpaid bill.
o NCV studies are eligible for Insurance reimbursement when
performed for any of the following indications:
-
Focal neuropathies or compressive lesions, for localization.
-
Traumatic nerve lesions, for diagnosis and prognosis.
-
Diagnosis or confirmation of suspected generalized neuropathies,
such as diabetic, uremic, metabolic, or immune.
-
Repetitive nerve stimulation in diagnosis of neuromuscular
junction disorders such as myasthenia gravis, myasthenic syndrome.
-
Differential diagnosis of symptom-based complaints (e.g., pain in
limb, weakness, disturbance in skin sensation or paresthesia)
provided the clinical assessment supports the need for a study.
o When performed for other conditions, NCV studies are
considered not medically necessary.

17.
What do patient need for NCV/EMG?
o Patient need to wear T-short/short pant or exam gown for
doctor to access nerves or muscles on the extremities.
