A Hidden Challenge in Workers' Compensation

By Dr. John Robinton, Medical Director, Neurodiagnostics, One Call Care Management

* One Call Care Management is the sponsor of the Claims Management Track at the 2018 AASCIF Annual Conference.

Electrodiagnostic Tests

Electromyography (EMG):

In this test, the physician inserts a small needle into the muscles to assess general health of the muscle and to test if the nerve supplied to that muscle is intact. Muscle activity is evaluated both while the muscle is at rest and during voluntary contraction.


Nerve Conduction Studies (NCS): These exams are essentially a quantitative measurement of nerve function. A mild electrical stimulation is applied directly over the nerve(s) in increasing strength to elicit a response from motor and sensory nerves.

Electromyography (EMG) and nerve conduction studies (NCS), known as electrodiagnostic tests, are valuable tools used for locating and evaluating the type and severity of muscle and/or nerve damage in injured workers. When performed correctly by properly trained and credentialed providers, accurate EMG and NCS results provide physicians with a baseline and roadmap to determine next steps in treating the injury.

The hidden challenge with these studies is the inconsistency with which non-prequalified physicians and non-physicians perform the tests and interpret the results. One study, presented at an annual conference of the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM), confirms this notion. Of the 140 EMG and NCS reports reviewed,

68 percent were not medically useful due to lack of adherence to AANEM guidelines, incomplete examination information, and data inconsistency and unreliability.

Today, entry into the field of electrodiagnostic medicine remains barrier free, and the quality of EMG and NCS providers continues to vary. To combat this challenge, it is crucial to employ guidelines and solutions to ensure the medical usefulness, quality, and accuracy of EMG and NCS tests. Following are some key factors to consider:

  • Credentialed EMG/NCS Provider Network—AASCIF members should consider the utilization of a specialized network with a stringent pre-qualification process. This approach can help to ensure that only highly trained neurologists and physiatrists are utilized who, in many cases, specialize in workers’ compensation claims. The credentialing process should include requirements such as the submission of sample reports to be reviewed by a medical director for quality, accuracy, and compliance with the National Guidelines for Electrodiagnostic Testing and Reporting. Additionally, board certification in neurology or physical medicine rehabilitation, or a certificate of completion from an accredited residency program in one of these fields, should be required to join the network.
  • Ongoing Quality Improvement and Review Program—Due to the persistent challenges in EMG and NCS testing, AASCIF members should see to it that any network panel developed or provided by a vendor has a well-established ongoing quality program to review reports and bills to ensure continual adherence to quality guidelines and proprietary standards. Through this program, deficiencies can be detected and corrected to improve outcomes on a prospective basis.

In workers’ compensation, more than half of EMG tests are performed by providers who have not undergone a pre-qualification or credentialing process, which results in the poor testing quality noted earlier.

A comprehensive quality improvement and review program can certainly provide a retroactive analysis of testing provided on a particular case, but perhaps even more importantly, can also look at the relative quality of EMG and NCS tests conducted both inside and outside of a given network panel.

This type of process allows for an objective opinion of whether the EMG or NCS was appropriately performed and if the exam is medically useful, while simultaneously providing real time feedback to service providers so they can pursue continuous improvement and provide the highest quality testing possible in the future. This proactive approach is a key step in helping to stem the flow of poor quality, ineffective tests, which are unfortunately all too common in the industry today.

Regardless of the approach used to develop a highly skilled EMG and NCS testing panel, AASCIF members should make certain that best practices such as those noted in this article are utilized to optimize the quality of care for injured workers by providing the necessary rigor and structure for an accurate and timely diagnosis.

For the management of EMG and NCS testing in the workers’ compensation field, an accurate, prompt, and complete diagnosis is the first step toward an effective treatment plan, rapid recovery, and favorable early return-to-work outcomes.
