About these listings

These are original name and office occurrences in the carrier's plan-specific directory, not a count of unique clinicians. Names have not been linked to NPI identities. County sections are the carrier's groupings and do not establish physical county boundaries. Check medical-group, referral and office requirements with the plan. A listing does not establish current appointments, coverage for a service, or access through every medical group. A missing listing does not mean out of network.
