Who Owns Centene Medicare?

Centene Corporation's origins are in Medicaid managed care, not Medicare. The company was founded in 1984 and built its business primarily around managing Medicaid programs for state governments. For most of its history, Centene had limited involvement in Medicare, focusing instead on expanding its Medicaid managed care operations across multiple states.

Centene began developing Medicare Advantage capabilities in the 2010s as the company sought to diversify beyond Medicaid and serve the full spectrum of government-sponsored health insurance. The company developed Medicare Advantage plans in select markets and began building the infrastructure needed to serve the Medicare population, which has different clinical needs and regulatory requirements than the Medicaid population.

The transformative event in Centene's Medicare history was the announcement in March 2019 of Centene's agreement to acquire WellCare Health Plans for approximately $17.3 billion. WellCare was one of the largest Medicare Advantage and Medicaid managed care companies in the United States, with a strong Medicare Advantage presence across multiple states. The acquisition was strategically motivated by Centene's desire to significantly expand its Medicare Advantage capabilities and membership.

The WellCare acquisition completed in January 2020, following regulatory approval. The acquisition added WellCare's Medicare Advantage plans, Medicare Part D prescription drug plans (operated under the SilverScript brand), and Medicaid managed care plans to Centene's portfolio. WellCare's Medicare Advantage membership, which numbered in the millions, transformed Centene from a primarily Medicaid-focused company into a major Medicare Advantage operator.

Following the acquisition, Centene retained the WellCare brand for Medicare Advantage plans nationally, recognizing that WellCare had strong brand recognition among Medicare beneficiaries. The WellCare brand is now Centene's primary Medicare Advantage brand, operating in multiple states across the country. In Florida specifically, WellCare's Medicare Advantage operations were integrated into the Sunshine Health organizational structure, though the WellCare brand name was retained for Medicare products.

SilverScript, WellCare's Medicare Part D prescription drug plan brand, became one of Centene's most significant Medicare assets following the acquisition. SilverScript is one of the largest Medicare Part D prescription drug plan sponsors in the United States, serving millions of beneficiaries who need prescription drug coverage under Medicare.

Centene has continued to expand its Medicare Advantage membership following the WellCare acquisition, both through organic growth and through the integration of WellCare's operations. The Medicare Advantage market has grown significantly as more Medicare beneficiaries choose Medicare Advantage plans over traditional Medicare, driven by the additional benefits that Medicare Advantage plans typically offer, including dental, vision, and hearing coverage.

However, Centene and other Medicare Advantage insurers have faced significant financial challenges in recent years as medical costs for Medicare Advantage members have increased faster than expected. Centene reported significant losses in its Medicare Advantage business in 2023 and 2024, leading the company to exit certain Medicare Advantage markets and reduce its Medicare Advantage footprint. Centene announced plans to exit multiple Medicare Advantage markets at the end of 2024 and 2025, focusing its Medicare Advantage operations on markets where it can achieve sustainable profitability.
