Dr. Pirruccello Explains How to Rate Spinal Injuries

By Jason Weinstock on September 28, 2014

Virginia :  The primary purpose of my blog posts is to inform Nevada’s injured workers about the law and the claims process.  However, I occasionally like to offer my readers from the workers’ compensation industry a more detailed analysis of a current issue that requires a working familiarity with Nevada workers compensation claims.   The following is a guest blog post by a well-respected Nevada rating doctor on a difficult  rating issue.  (Chiropractors on the DIR’s list of rating doctors  are  qualified to rate any injury to the musculoskeletal system.)

Under the 5th edition of the AMA Guides to Permanent Impairment, when a rating doctor is evaluating a cervical, thoracic, or lumbar spine injury, such as a herniated disc, the doctor must correctly  choose one of two rating methods in the book.  Whether the rating doctor uses the  range of motion method , or uses a DRE category can significantly change the percentage of impairment.   Ultimately, the  amount of money the injured worker receives as his PPD award, will be affected.  I asked Paul Pirruccello, D.C,  currently on the DIR’s panel to review Nevada ratings for errors,  to explain when the Guides require that the rating doctor use the Range of Motion method of rating spinal injuries:


When Should the Range of Motion (ROM) Method Be Used for Spinal Impairment?

When an adequate number of PPD ratings have come across your desk, you will inevitably come across spinal ratings where the ROM Method has been used because the rating doctor thinks there is “multilevel involvement.”  The major concern in these cases lies in the rater’s understanding of the AMA Guides definition of multilevel involvement.  The proper utilization of the ROM Method is best defined in Section 15.2a #4 on page 380 of the AMA Guides, as follows:  a. Fractures at more than one level in a spinal region. b. Radiculopathy bilaterally or at multiple levels in the same spinal region. c. multilevel motion segment alteration (such as multilevel fusion) in the same spinal region. d. Recurrent disk herniation or stenosis with radiculopathy at the same or a different level in the same spinal region.

The key findings that must be associated with multilevel involvement, when using the ROM Method are: fractures, radiculopathy or alteration of motion segment integrity (fusion).  Without one of these key findings the ROM Method should not be used.
I have oftentimes seen PPD reports where raters have used the ROM Method for multilevel degenerative disc disease, multilevel disc bulges, multilevel strain/sprain injuries or multilevel disc herniations without multilevel radiculopathy.  None of these qualify for use of the ROM Method.  Always think multilevel fractures, radiculopathy or fusion when you think of the ROM Method and multilevel involvement.  Without these qualifiers, the DRE Method is used.
