you are most likely better off purchasing a medigap policy than purchasing a full medical policy through the marketplace. medigap policies are designed to wrap around medicare coverage and fill in the gaps in coverage. to get help finding a medigap policy you can contact your local state health insurance assistance program ( <link> ). there is nothing to prevent you from purchasing a policy on the marketplace but you would not qualify for a premium subsidy because you already have medicare and it may not be the best policy for you given you have other coverage.
can a marketplace plan be used as a supplemental policy with medicare as the primary?
