I'm so pissed off. I called my health plan to switch pediatricians cause I couldn't stand the one my son has. He already has his first vaccinations scheduled at his pediatricians though so I asked if switching would cause an issue with that appointment and the insurance said no because the switch isn't effective until the first of July. So I went today to get his shots and they refused to see me. According to them it's because they're not his pediatrician anymore. Jokes on them though. My mom was with me and she works in a doctors office too. They were supposed to see me but they're butt hurt that I'm switching pediatricians so they won't. I'm calling the health plan today to see what can be done since I can't see the new pediatrician until the first.. What am I supposed to do if he gets sick?! This is such crap 😡
