Checking my last day of health coverage, bookkeeper here

I was told my coverage ends on my last day, but the letter says the end of the month. It has been weighing on me all week. I do not want to be surprised by a bill. Did coverage match what HR said?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

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