Medical Business Systems

Dr. Michael Kos, M.D. - President

Dr. Kos grew up in Canada and is fluent in French. At age 13 he was interested in software and was programing his own video games on a commodore PET. At university his primary interests included economics and science. He completed medical school and residency in Radiation Oncology in Canada. He opened his own practice in Reno Nevada and required billing software. Billing software with the specific needs of a Radiation Oncologist did not exist.
Accountability and biller productivity were well known concepts in economics but not in the field of medical billing. Using his knowledge in programing, economics and Radiation Oncology Dr. Kos used his expertise to build a company that would commercialize the best Radiation Oncology billing system. Having medical billers design a system to enhance work flow and productivity was an obvious first step. He and his team continue to automate the billing processes to maximize worker productivity. Dr. Kos continues to practice Radiation Oncology on a full time basis. His primary clinical research interests in Radiation Oncology are stereotactic radiosurgery and high-dose
rate brachytherapy for prostate cancer.
Dr. Kos enjoys cooking, skiing, mountain biking, playing with his two children and reading.
