Arizona ACA Premiums Projected to Jump About 28% for 2027

Average premiums on Arizona’s ACA marketplace are projected to rise about 28 percent for 2027, roughly double the national average of about 15 percent, KJZZ reported Oct. 29. Healthinsurance.org puts insurers’ weighted average proposal at about 29 percent before subsidies.

Katherine Hempstead of the Robert Wood Johnson Foundation told KJZZ that Arizona is among the highest-increase states. Causes include rising health and drug costs and the expiration of enhanced federal premium subsidies at the end of 2025, after which healthier people dropped coverage, KJZZ reported. Arizona’s enrollment for 2026 was 357,144, down from a record in 2025, according to healthinsurance.org.

Cigna is exiting the Arizona marketplace at the end of 2026, leaving six insurers for 2027 instead of seven, healthinsurance.org reported. Open enrollment runs Nov. 1 to Jan. 15, 2027; plans chosen by Dec. 15 start Jan. 1.

Hempstead advised shoppers to compare plans rather than auto-renew, noting that a plan with a higher premium can be the better deal if it has lower deductibles and copays. The Arizona Department of Insurance and Financial Institutions publishes shopping guidance.
