Following up on insurance

Hi all -

I'm currently working my way through the insurance waiting period to get the Gastric Sleeve. How often does everyone follow up with their bariatric facility on this process? I want to ensure things keep moving along as I have been working this process for nearly a year across two different facilities. I followed up with them last week and they stated they were waiting for one last piece of paperwork to be processed and would likely be submitting the next day and that they would let me know once they had submitted. My current plan is to follow up once a week, but, I also don't want to become that annoying patient everyone hates to see an email from. I had been previously approved by my insurance with the original facility I was working with, however, decided to change to a new facility due to some ongoing communication issues that left me feeling uncomfortable about the original place. I'm sure the fact that I had been previously approved is making me a bit more anxious about getting this done again, so, I'm trying to keep that in mind as well. It's such a long process and is definitely hard to stay focused on the bigger picture at times.
