<prompt> Human: Background: My parents have fantastic health insurance that I have been using since college. When I started my new job last October, I bought coverage through my employer a big, corporate firm leaving me with double coverage health insurance through my parents and employer.It turns out my employers health insurance is quite shit, and since it is considered my primary insurance this has resulted in significantly increased out of pocket expenses--causing me to pay for things that were always 100 covered.My question: Can I cancel my employers health insurance plan and revert to using my parents as my primary coverage? Is there any special proceduretimeline for this, or can I just cancel the worse plan?  <response>: Yes, you can use your parents as your primary coverage.
