CMS ACO ID A1290. 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.
