Short answer
This is a structure choice, not just a premium comparison.
Medicare Advantage is an alternative way to receive Medicare benefits through a private plan. Medigap is private supplement insurance used with Original Medicare. Medicare.gov treats those as different paths, so the plan has to compare networks, premiums, drug coverage, and out-of-pocket risk.
