Results

  • Ordoniz v. Dano Auto Body – Petitioner claimed he injured his low back and allegedly suffered a herniated disc while removing a car door from a vehicle. He amassed approximately $225,000 in outstanding medical bills for treatment in chiropractic care, physical therapy, medications, numerous spinal injections, radiofrequency ablation, and numerous radiological tests. The Workers' Compensation Commission relied on our IME and Utilization Review reports to find that the petitioner suffered a lumbar strain and denied approximately $225,000 in alleged outstanding medical bills as unreasonable, unnecessary, and causally unrelated to the work injury. The Commission awarded 3% person-as-a-whole.
  • Alanis v. Woodstock Christian Life Services – Petitioner injured her lower back while pushing a cart and slipping and falling on some water. She received medical treatment for approximately one month and was then released to return to work. She eventually began treating with a pain management physician who performed a series of lumbar spine injections and a radiofrequency ablation. When the pain management physician released the petitioner after one year of treatment, the petitioner had accumulated an extensive amount of outstanding medical bills which we denied. Relying on our IME physician, the Workers' Compensation Commission denied approximately $34,000 in alleged outstanding medical bills and awarded 6% person-as-a-whole for a lumbar strain.
  • Hieber v. Glass and Mirror Company – Petitioner suffered a compensable and accepted right shoulder injury. Following right shoulder surgery, the petitioner developed an infection in the right shoulder, resulting in revision surgery. Subsequent to the second surgery, the petitioner suffered from kidney failure and eventually required a kidney transplant. On behalf of the glass and mirror company, Heyl Royster presented evidence and an expert opinion that the renal failure was not related to the right shoulder surgeries and infection, that the petitioner had risk factors for developing renal failure, and that petitioner subsequently developed renal failure in the transplanted kidney. The arbitrator found the petitioner's renal failure to be causally connected to the right shoulder work injury and awarded all benefits related to the renal failure. On review, the Worker's Compensation Commission found no causal connection between the work injury and the petitioner's kidney condition, and the circuit court affirmed on appeal. The Commission's decision resulted in a reduction of the arbitrator's award of more than $300,000.
