@HappyDay45 - Normally health information technicians do not have any patient contact. They work with patient records. You will need to have a fairly good foundation in math since you will need to take courses in science and computers, but the main focus of this career is not math it is working with patient health records.
As mentioned in the article you will need to understand medical terminology and it is helpful to have strong computer skills. You will receive training in databases and statistics which requires some basic understanding of math.
