On May 8, 2009, employee complained of throat and eye irritation, coughing and wheezing after exposure to Cypermethrin sprayed around air conditioning units in her work place to control ants. Employee sought emergency room treatment on May 11, 2009. She thereafter returned to work immediately without limitations in regard to ant spray exposure.
In response to employee's continued complaints, employer sent her to occupational and environmental medicine specialist Dr. Eddie Runde for additional evaluation on May 22, 2009. In addition to employee, another person with a small dog was sitting in Dr. Runde's waiting room. While Dr. Runde's receptionist escorted employee from the waiting room to the patient area, in the process of attempting to divert the dog, Dr. Runde accidentally kicked employee under her right knee, causing her to trip and fall on her knees. As part of his evaluation, prior to discharging employee that day, Dr. Runde examined employee's knees. He found that she had some mild erythema, full range of motion, and was able to walk with normal gate. Dr. Runde released her to regular duty with no restrictions, and noted that no permanent disability would be expected related to her May 8, 2009, Cypermethrin exposure.
In August 2009, employer sent employee to Dr. Thomas Hyers for an independent medical evaluation. Dr. Hyers opined that employee's work exposure to ant spray was not the prevailing factor for any current complaints regarding her pulmonary functions. Dr. Hyers diagnosed employee with transient bronchitis. He opined that her work caused merely a temporary irritation that would have resolved in a matter of days after the initial exposure.
Dr. Volarich evaluated employee at her attorney's request on July 21, 2014. Dr. Volarich provided the following disability ratings relating to employee's primary, May 8, 2009, injury:
- 5% PPD of the body as a whole due to pulmonary exposure to Cypermethrin
- 15% PPD of the body as a whole due to cervical strain/sprain with aggravation of headaches
- 25% PPD of the body as a whole rated at the lumbar spine due to irreversible aggravation of her lumbar syndrome
- 25% PPD of the left upper extremity rated at the shoulder due to adhesive capsulitis
- 45% PPD of the left lower extremity rated at the knee due to bicompartmental meniscal tears and chondral injuries
On June 3, 2015, orthopedist Dr. George Paletta evaluated employee and assessed the following:
- End stage osterarthritis left knee, moderately severely symptomatic; and
- Degenerative joint disease right knee, minimally symptomatic
Injury No.: 09-034298
Employee: Lucille Schoen

Dr. Paletta ultimately concluded that employee's underlying chronic, progressive degenerative joint disease, not her May 8, 2009, injury was the prevailing factor in her need for future medical treatment.
Lastly, Dr. Michael Chabot evaluated employee on July 31, 2015. After reviewing the medical records and imaging studies, Dr. Chabot diagnosed the following conditions:
- History of trip and fall/back contusion;
- Back strain;
- History of chronic multi-level degeneration involving lumbar spine; and
- History of bilateral knee joint arthritis.
Dr. Chabot opined that symptoms relating to employee's strain injury had resolved, that she had reached maximum medical improvement, and that the employee's present complaints "are causally related to multiple pre-existing medical conditions to include multi-articular arthritis more specifically involving the knee joints, multi-level disc degeneration and facet degeneration involving the lumbar spine and degenerative spondylolisthesis unrelated to her work injury."
The employee alleged disabilities relating to her May 8, 2009, ant spray exposure involving pulmonary issues, left knee pain, left shoulder pain, low back pain, and neck pain with headaches.
The ALJ found that the parties "appear[ed] to concede" that injuries employee claimed to sustain as a result of the May 22, 2009, incident in Dr. Runde's office were compensable as part of her May 8, 2009, Cypermethrin exposure. Noting language in *Meinczinger v. Harrah's Casino* to the effect that "Injuries sustained during authorized medical treatment of a prior compensable injury are the natural and probable consequence of the compensable injury," the ALJ found that injuries the employee sustained while she was seeking authorized treatment from Dr. Runde on May 22, 2009, were compensable as part of her May 8, 2009, Cypermethrin exposure. Considering medical records, medical opinions, employee's testimony and her advanced age the ALJ found employee permanently and totally disabled due to her May 8, 2009, work injuries considered in isolation, including injuries employee sustained in the May 22, 2009, incident in Dr. Runde's office.
Employer's application for review alleges "The ALJ erred by including alleged injuries to Employee's left knee, right knee, left shoulder, left hip, lumbar spine, and neck when assessing the nature and extent of her primary work-related injury." On appeal, all parties brief the issue of compensability of injuries allegedly sustained by employee on May 22, 2009, in the office of her authorized treating physician, two weeks after her work injury on May 8, 2009. No party disputes that this issue is properly before us for review.
