When does my employer coverage actually end? after 3 years as a medical assistant

HR said my health plan continues for a bit and I do not understand how. I do not want to be surprised by a bill.

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 settled down once I kept a simple log of every call and form.
