CMS ACO ID A5202. Public reporting / administrative contact from the CMS PY2026 dataset, modified April 16, 2026. This is not a claims, eligibility, enrollment, or urgent clinical line. State tags identify states containing counties where more than 1% of assigned beneficiaries reside; they are not a statewide service-coverage or eligibility guarantee. The ACO reporting website was supplied in the dataset and was not individually reviewed in this batch.

Published ACO primary administrative contact. This source does not designate a claims, health-plan member-services, billing or urgent clinical line. No office hours or dedicated fax were published in the reviewed section. State tag US is not a service-area assertion. Current reporting page names Leslie Southworth as the primary contact and ACO executive. Named staff email omitted. This phone differs from the existing CMS dataset phone. Performance entries through 2027 are reporting fields, not proof of source publication date or future contact availability.
