I revised the paragraph:
During my online research, I was very excited to learn about the current opening for a medical coding position in your organization. I feel my qualifications and your requirements are a good match. I have been very interested in medical coding since my father's illness. I was always interested in what the doctors had written down in my father's medical records which was the type of illness, and how that was coded from the medical record to the insurance company. This curiousity stayed with me, and I thought what if the information the doctor entered was coded wrong by the office staff, this would lead to one mistake after another. For instance, the wrong coding would lead to the wrong insurance billing, and the Insurance company may not pay for the doctors visit or hospital stay. The people it would affect would be the doctors, insurance companies, and the patients. My mind would just be racing with ideas, and the mistakes that could happen, which led me to take courses on medical coding. I now want to pursue a career in medical coding. I want to use my knowledge and skills to the best of my ability. I want to be the person who helps enter the information correctly and help others by doing so.
