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.
