 Click 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.
