California shoppers face major 2027 health plan shakeup

California residents are heading into a crowded enrollment season marked by higher rates, carrier exits and major Medicare network changes. Medical Insurance Today is offering free reviews to help people keep doctors, prescriptions and coverage aligned for 2027.

Why it matters: - Californians could see higher out-of-pocket costs, narrower networks and prescription disruptions if they auto-renew without checking plan changes for 2027. - The stakes are especially high for people on Covered California, small business coverage and Medicare Advantage, where carrier exits and network losses can force people to switch plans or doctors. - Medical Insurance Today says a human-led review can help households avoid coverage gaps and find plans that better match doctors, drugs and budgets.

What happened: - Thomas Feeney, founder and licensed agent at Medical Insurance Today in Costa Mesa, said California residents face more health insurance changes this enrollment season than in recent years. - Covered California announced a weighted average rate increase of 9.9 percent for 2027. - Molina Healthcare is leaving the Covered California marketplace in Orange County and northeast Los Angeles County for 2027, affecting about 1,600 enrollees. - CalOptima Health is entering the Orange County marketplace as a new option. - Health Net is exiting California's small and large employer group market, with group coverage ending Feb. 28, 2027. - Several Medicare Advantage network changes are also hitting Orange County, including Hoag, SCAN, UnitedHealthcare, UCI faculty physicians and Aetna PPO coverage.

The details: - Covered California estimates about 60% of enrollees will see no meaningful premium increase in 2027 because of remaining federal tax credits and a new $300 million state subsidy program for households earning up to 200% of the federal poverty level. - New federal verification rules under H.R.1 could change eligibility in either direction. - Rate changes vary by carrier and region, so some households may lower costs by comparing plans within the same metal tier or by switching between Gold and Silver plans with cost-sharing reductions. - Hoag's contract with SCAN Health Plan for Medicare Advantage HMO members expires Dec. 31, 2026, and Hoag physicians, specialists and facilities will no longer be in network for SCAN HMO members starting Jan. 1, 2027. - SCAN is reassigning affected members to new primary care physicians outside Hoag. - Emergency care is not affected, and patients in active treatment may be able to request continuity of care. - Hoag lists its AARP Medicare Complete Secure Horizons Plan 2 contract as ending Dec. 31, 2026, with AARP Medicare Advantage from UHC CA-46 as the UnitedHealthcare plan that will keep Hoag in network in 2027. - Blue Shield of California members already lost in-network access to Hoag's physician group in 2026, though Hoag hospitals remained in network. - UCI University Physicians & Surgeons, including UCI faculty and UC Irvine Medical Center affiliated providers, will leave SCAN's network on Dec. 31, 2026. - The separate UCI Health Plan Network, including UCI-affiliated hospitals in Lakewood, Los Alamitos, Fountain Valley and Placentia-Linda, remains in network. - Aetna will not offer individual Medicare Advantage PPO plans anywhere in California next year, including plans previously sold in Orange and Los Angeles counties. - Members whose plan is ending should receive a non-renewal notice and may have special enrollment rights, including the ability to buy a Medicare Supplement plan without medical underwriting in many cases. - Members whose plan continues but whose doctors are leaving usually do not get those same protections, making the Medicare Annual Enrollment Period, Oct. 15 through Dec. 7, the main chance to act. - Californians approaching 65 should start planning several months before their birthday because initial Medicare enrollment deadlines are strict and missed deadlines can trigger permanent late enrollment penalties.

Between the lines: - The biggest risk is not any single rate hike or network change; it is assuming last year's plan will still fit this year's doctors, drugs and costs. - Feeney said many members with SCAN, UnitedHealthcare or Aetna coverage do not know whether they are facing a plan ending or a doctor leaving the network, and those are two different situations with different rights and deadlines. - The enrollment environment favors people who act early, especially households that need to keep a specific hospital system such as Hoag or UCI. - Auto-renewal can look safe but still lead to higher costs, lost drug coverage or a different network starting Jan. 1.

What's next: - Medicare Annual Enrollment runs Oct. 15 through Dec. 7, 2026. - Covered California Open Enrollment runs Nov. 1, 2026 through Jan. 31, 2027, with enrollments completed by Dec. 15 taking effect Jan. 1. - The Medicare Advantage Open Enrollment Period runs Jan. 1 through March 31, 2027, and allows current Medicare Advantage members one plan change. - Health Net employer group coverage ends Feb. 28, 2027. - Medical Insurance Today is offering free consultations by phone, online or in person at its Costa Mesa office, and the agency says its team is set up for Medicare, Covered California, individual and family plans and employer coverage.

The bottom line: - For 2027, Californians cannot assume renewal means continuity. They need to check doctors, prescriptions, subsidies and total costs before the deadlines hit.
