Ascension sells Arizona Medicaid plan stake to Aetna

Ascension has sold its ownership in an Arizona Medicaid managed-care plan to Aetna, according to Healthcare Dive. The transaction allows the Catholic health system to shed insurance risk associated with operating the plan.

For Aetna, the purchase provides a stake in a profitable plan that serves dual-eligible members — those enrolled in both Medicare and Medicaid. These members are often seen as high-margin for insurers, making the plan an attractive asset.

The sale highlights a broader shift in which health systems retreat from insurance operations while payers expand into government-backed programs. Ascension reduces its financial exposure, and Aetna strengthens its presence in the Arizona Medicaid market.
