Medicare & insurance

Insurance participation is not established by these public records. Ask the practice and your insurer about your specific plan and this location.

How to check your coverage

Use your plan’s provider directory or the member-services number on your insurance card. Confirm the clinician, practice address, service, and whether a referral is required. A missing opt-out record does not establish Medicare acceptance.
