Checking my last day of health coverage - any advice?

I am not sure what date my benefits stop after being let go as an office manager. It has been weighing on me all week. The letter is unclear about dental and vision. How did you confirm your end date?

Ask HR to confirm the exact date in writing. I also called the insurance company to double-check.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
