Centene subsidiary Health Net confirmed this month that it is exiting the traditional commercial group health insurance market in California and Oregon entirely, ending every small- and large-group HMO, PPO and POS plan sold to employers in both states. The insurer began notifying employers and brokers on Sept. 1, giving them roughly 18 months before coverage actually lapses. For older workers and near-retirees who count on an employer plan to bridge the years before Medicare eligibility, the timeline compresses fast: renewal season, a new-carrier search and open enrollment all have to happen inside a single plan year.
Every group product, not one line of business
Health Net’s decision is a full retreat from employer-sponsored coverage, not a pruning of one segment. The exit reaches every small-group and large-group HMO, PPO and POS product the insurer sells to employers in both states, regardless of size or plan design. If an employer’s health plan currently runs through Health Net’s commercial group book, it is being discontinued, and the company has framed the move as a strategic choice rather than a response to financial distress at the subsidiary.
A company spokesperson told Becker’s Payer that Health Net “has made the decision to exit the traditional commercial group business in California and Oregon in order to focus on government sponsored healthcare”. The last day of coverage is Feb. 28, 2027, “or as otherwise permitted by the applicable contract and regulatory requirements,” according to that statement. That single date now anchors renewal planning for every affected employer plan, including the retiree and early-retiree carve-outs some employers still administer through group contracts rather than separate Medicare supplement policies purchased individually.
Brokers who work with small and midsize employers in both states are the first line of the transition. They now have to identify a replacement carrier, requote every affected group, and walk each employer through a mid-cycle plan change before the Feb. 28, 2027 cutoff — work that typically happens once a year during a normal renewal, not on a compressed, carrier-forced timeline.

Health Net built its California footprint on Medicaid, not payrolls
The commercial group business Health Net is shedding was already the smaller share of its California footprint. About two million of the roughly three million Californians enrolled in a Health Net plan are Medi-Cal beneficiaries, coverage the company says the group exit does not touch. Health Net also continues selling individual and family marketplace plans under its Ambetter brand through Covered California, and Medicare products through sister brand Wellcare, leaving commercial employer contracts as the one line of business it is walking away from entirely.
Health Net has been a Centene subsidiary since 2016, when Centene closed a $6.8 billion acquisition that state insurance regulators approved a year earlier — Oregon’s Division of Financial Regulation signed off on the sale of Health Net’s Oregon plan in November 2015, ahead of the broader corporate merger. A decade later, the group-market retreat points toward Centene consolidating both states’ Health Net operations around the Medicaid and Medicare Advantage business it already dominates, rather than continuing to compete for employer payroll business against Kaiser Permanente, Blue Shield of California and other regional group carriers.
Health Net employs more than 5,700 people across California, and the group exit does not by itself put those jobs at risk since the company still administers Medi-Cal, marketplace and Medicare business in the state. The retreat is narrower than a full market exit — it is Centene deciding which insurance lines are worth running under the Health Net brand, and commercial group coverage did not make the cut.
The coverage gap that lands on people closest to Medicare
Nothing in Health Net’s announcement touches Medicaid, the ACA marketplace or Medicare, and that is precisely why the group exit falls hardest on people not yet eligible for any of those programs. Employees in their late 50s and early 60s who rely on an employer’s Health Net plan, along with early retirees whose former employer continued their coverage through a retiree group contract, now have a fixed deadline to find a replacement plan before their current one simply stops existing.
Some of those workers and early retirees are covered today only because they elected COBRA continuation coverage after leaving a job, extending an employer plan they would otherwise have lost. Federal COBRA rules let a qualified beneficiary keep a group health plan for up to 18 months, and sometimes longer, after employment ends, but that continuation right is tied to the underlying employer plan itself. If Health Net discontinues the plan by Feb. 28, 2027, COBRA cannot continue a policy that no longer exists, regardless of how much of that window a beneficiary has left.
Small employers are especially exposed. Losing a carrier reduces competition in California and Oregon’s small-group markets, and businesses forced to shop for coverage outside their normal renewal cycle typically have less leverage to negotiate a favorable quote. That exposure is sharper for employers with older workforces, since group insurers have long priced small-group premiums higher for enrollees closer to retirement age than for younger employees on the same plan.
Employers now carry the administrative cost of re-bidding group coverage with a new carrier before that date, and every employee, near-retiree and COBRA beneficiary tied to the old plan inherits whatever gap sits between the final Health Net premium payment and the first payment on whatever replacement their employer selects. Health Net has not disclosed how many California and Oregon employer groups the exit touches, only that notices are already going out — leaving the true size of the transition, and how many employers wait until late 2026 to act, an open question for regulators in both states.
