I have run out of options with a primary care doctor at our facility. He has over 500 notes left unsigned going back all the way to August 2018. I have sent multiple messages to him to try and get them done, I've sent bulk messages telling him which ones need done, I've sent individual messages, anything to make it easier on him but my messages go unanswered. My office manager is aware and tries to get him to do them but he doesn't listen to her either. The CEO of the company is even aware but he doesn't do anything about it. I have run out of options and I don't know what else to do. I hate having all of these sitting here because then I can't do my job correctly. I wasn't sure if there was a way to report it somewhere or what can be done because whatever I'm doing is not working.
