Checking my last day of health coverage - 19 weeks in

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. 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.

Keep a copy of any coverage confirmation in case of later disputes.
