Frequently asked questions about medicare advantage (part c) plans
Does guidance cost me anything?
No additional fee is charged to you for O’Neal Insurance Group’s guidance. Agents may be compensated by an insurance carrier when an enrollment occurs.
Is every plan available through the agency?
No. The agency does not offer every plan available in every area. Availability depends on location, eligibility, carrier appointment, and product availability.
Can I keep my doctors?
That depends on the specific plan’s current network. We can help you check the provider directory and encourage confirming directly with the provider.
