Can I switch plans mid-year?

You can switch plans mid-year under a Special Enrollment Period (SEP) only if you are eligible under certain situations otherwise you would have to wait for an Annual Enrollment Period (AEP) which runs from October 15 through December 7. To qualify for an SEP you would need to be eligible, for instance you move to a new service area or your existing plan no longer offers coverage. You should call Medicare to see whether your specific situation would allow you to switch plans.
