- In May of 2003 the employee started working for Centene Management as a claims analyst. Her job required her to take care of appeals after claims were denied, and she spent most of her time entering data and typing on her computer.
- In February of 2004 the employee started developing pain in the left side of her neck with numbness and tingling in her shoulder. She later developed swelling in her right arm and reported her symptoms her employer.
- After the doctors selected by the employer-insurer failed to correctly diagnose her condition or relieve her symptoms, the employee returned to see Dr. George Schoedinger. Her initial appointment was on June 28, 2004.
- An MRI and a myleogram confirmed the employee had left paracentral disc protrusions at both the C4-5 and
C6-7 levels. After conservative treatment failed to improve the employee's symptoms, Dr. Schoedinger ordered a discography at both levels. Based on the discography, Dr. Schoedinger recommended a fusion at the C4-5 level. After discussing the issue with the employee, Dr. Shoedinger decided not to fuse the C6-7 level because he wanted to avoid a 3-level fusion (employee's exhibit K, page 14).
- On September 9, 2004, Dr. Schoedinger performed an anterior discectomy and instrumented interbody fusion at the C4-5 level (employee's exhibit M).
- Prior to her surgery, the employee had changed employers, and was working for Hawthorne Billing Group from June 25, 2004 until the day before her surgery on September 8, 2004. Following her surgery, Dr. Schoedinger allowed the employee to return to work on October 25, 2004. The employee initially worked part time, and gradually tried to increase her hours. Within a few weeks the employee developed headaches and pain with numbness and tingling down both arms. On November 17, 2004, the employee called Dr. Schoedinger, and he advised her to stop working and scheduled her for an appointment on November 18, 2004. Dr. Schoedinger then recommended additional physical therapy.
- After the physical therapy increased her symptoms, Dr. Schoedinger saw the employee on December 6, 2004, and determined that she had reached her maximum level of medical improvement. Dr. Schoedinger suggested that the employee apply for social security disability, and released her on a "p.r.n." basis (employee's exhibit M). The employee applied for and received social security disability in April of 2005.
- In a follow-up letter dated January 4, 2005, Dr. Schoedinger gave the employee a 20\% impairment rating, but deferred any opinion regarding her ability to work pending a functional capacity evaluation (employee's exhibit M).
