Dr. Hagstrom is a competent dentist, but his billing charges are always overstated. It seems that his staff can never get insurance reimbursements correct, and consequently are always sending me bills that are not my responsibility. They also overcharge the insurance company by using incorrect codes. My son had a custom mouthguard made for wrestling, and the insurance company was billed close to $1,000. When I asked about it, I was told that it was an error, but I've noticed that they never submitted paperwork to correct the error. I'm looking for a new dentist.
