Original Medicare status

Most Medicare Supplement (Medigap) policies have no provider network: they help pay Original Medicare's cost sharing where Medicare is accepted. Medicare SELECT policies can require network providers for full benefits. Ask the office whether they accept Medicare.

Medicare enrollment and assignment have not been verified here. Advantage directory results do not answer this question.

No opt-out record in this CMS file. CMS's file covers data through 2026-08-31. This does not establish Medicare enrollment, assignment, or whether the office accepts new Medicare patients.
