Checking my last day of health coverage - 2 months and counting

HR said my health plan continues for a bit and I do not understand how. I do not usually post, so bear with me. The letter is unclear about dental and vision. What should I do about appointments?

Thanks for writing this out. I went through something close to it 2 months ago, and it settled down once I kept a simple log of every call and form.

I moved my appointments earlier while coverage was active. It saved me a bill.
