Seven health insurers selling coverage on Arizona's Affordable Care Act marketplace have filed proposed rate increases for 2027 ranging from 3.26% to 33.90%, according to Arizona's Family, with the filings coming as enrollment in the state dropped by nearly 66,000 people between 2025 and 2026.
Data from the Centers for Medicare & Medicaid Services shows 357,144 Arizonans selected marketplace coverage for 2026, down from 423,025 the prior year. The proposed increases published on ratereview.healthcare.gov are: Antidote Health Plan of Arizona, 3.26%; Blue Cross Blue Shield of Arizona, 29.59%; Health Net Community Solutions of Arizona, 27.96%; Arizona Complete Health, 24.55%; Imperial Insurance Companies, 30.08%; Oscar Health Plan, 33.90%; and UnitedHealthcare of Arizona, 28.63%.
Natasha Murphy, Director of Health Policy at the Center for American Progress, said the proposed increases were not a surprise given the enrollment decline and the current legislative environment. "The unfortunate reality is that the increase in those prices and the subsequent drop in enrollment and coverage is unfortunately feeding into some of the high rates that we are seeing proposed for 2027," Murphy said. She added that many carriers cited a sicker risk pool as justification, and that coverage losses carry consequences beyond premiums: as uninsured patients seek care in emergency rooms, hospitals absorb higher uncompensated care costs, a dynamic that can threaten rural hospital viability.
Adena Hope Bank, a self-employed clinical social worker in Pima County who relies on the marketplace as her only coverage option, said she currently pays roughly $1,089 a month and is already limiting medical visits to manage costs. She said a further increase of $200 a month would likely push her off the marketplace entirely.
The story has been corroborated by AZPM and the Arizona Mirror, both of which reported on the proposed increases and the enrollment decline independently.
The figures are proposals only. Federal and state regulators will review them and may make changes before premiums are finalized. Open enrollment begins Nov. 1.
