What Happened to Cigna's ACA Market Exit?

Cigna's journey within the Affordable Care Act (ACA) individual health insurance marketplace has been dynamic, characterized by initial commitment and expansion, followed by strategic withdrawals. Unlike some competitors who exited early, Cigna maintained a continuous and growing presence in the ACA exchanges since their inception in 2014, viewing it as a significant market opportunity.

Throughout the early to mid-2020s, Cigna actively expanded its footprint. For the 2021 plan year, it grew its reach to 220 counties across 10 states, adding 79 new counties, including a significant expansion in North Carolina. This expansion continued into 2022, with Cigna offering plans in 313 counties across 13 states, entering Georgia, Mississippi, and Pennsylvania. By 2023, the insurer further expanded to 363 counties spanning 16 states, adding Texas, Indiana, and South Carolina to its portfolio. These expansions were often attributed to the company's ability to form strong provider partnerships and offer competitive, affordable plans, especially as the market stabilized and federal subsidies encouraged enrollment.

However, by 2024, Cigna began making some targeted withdrawals, exiting the ACA exchange markets in Kansas and Missouri, along with two counties in Utah and Arizona, while still expanding in other areas like North Carolina, maintaining a presence in 14 states and 350 counties. For the 2025 plan year, Cigna offered plans in 11 states and 337 counties, indicating a slight contraction. The company continued to offer plans in 11 states for the 2026 plan year, though with some localized exits, such as from Cook County, Illinois.

The most significant turning point occurred on April 30, 2026, when The Cigna Group announced its intention to fully exit the individual health insurance exchange market after the 2026 plan year, meaning it will not offer ACA plans starting in 2027. This decision will impact approximately 369,000 health plan members across 11 states. Incoming CEO Brian Evanko stated that the move was a strategic decision to focus on core growth platforms, such as Evernorth Health Services and its U.S. employer business, as the individual exchange business was small and shrinking, and Cigna did not see a clear path to achieve meaningful scale. A key contributing factor cited by industry analysts and Cigna itself is the expiration of enhanced federal subsidies for ACA plans at the end of 2025, which is expected to lead to higher premiums, lower enrollment, and a sicker risk pool in 2026 and beyond. This makes Cigna the second major insurer, after CVS Health's Aetna, to announce a full exit from the ACA marketplace for 2027, signaling a period of renewed instability in the individual market.
