Checking my last day of health coverage - 3 months and counting

I was told my coverage ends on my last day, but the letter says the end of the month. I am in Nashville, in case local advice matters. I have an appointment next week. How did you confirm your end date?

Keep everything in writing and save the confirmation numbers. It saved me later.

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