Your Health Net replacement is a network decision before it's a rate decision.
Affected California group medical coverage ends February 28, 2027. California has a deep group market, so the question isn't whether alternatives exist — it's which one moves your employees with the least disruption. Here's how we compare them.
Why this page doesn't rank "the best" replacement carrier
Because the answer genuinely differs by employer. Group medical availability in California turns on your county, your group size, how many employees enroll, and each carrier's underwriting and participation rules. A ranked list would be wrong for most of the people reading it — and in the small-group market, where every carrier files the same rates with every broker, a list of names tells you nothing you can act on. What follows is the comparison itself.
Three things that cost more than rate.
Network match, employee by employee
This is where a Health Net replacement usually goes wrong. Run your actual employee roster against each candidate network before you look at rate — primary care physicians, specialists in active treatment, and the hospitals your people would choose in an emergency. An HMO that excludes one popular medical group can generate more disruption than a 10% rate difference.
Narrow-network HMOs priced attractively because they exclude a hospital system your employees use.
Formulary and active prior authorizations
Prescription coverage is not portable. A drug on Health Net's formulary may sit on a higher tier, require step therapy, or be excluded entirely under the replacement. Active prior authorizations generally have to be re-established with the new carrier, which takes time you need to schedule before the effective date.
Specialty medications and anything an employee takes continuously — these produce the loudest surprises in week one.
Deductible credit you have to ask for
Most California carriers will credit a deductible already satisfied with the prior carrier — Health Net, Blue Shield, UnitedHealthcare, Anthem, Aetna and Cigna + Oscar all document a program for it. It is never automatic: it takes Explanation of Benefits statements filed inside a 30-to-90-day window, plan types generally have to match, and out-of-pocket maximums usually cannot be credited. Miss the window and employees genuinely do restart at zero, which is why this belongs in the implementation plan rather than the fine print.
A February 28 end date puts most groups mid-plan-year. Get the credit rules in writing before you choose an effective date.
A carrier change is also a chance to revisit the structure.
Most employers replace like with like because it's the fastest path. It's worth at least pricing the alternatives while the group is already in motion.
Fully insured small group
Most groups under 100 eligible employeesIn the ACA small-group market every carrier files the same rates with every broker, so the differentiator is plan design, network fit, and contribution strategy — not who quotes it. Rates are pooled and community-rated, so your own claims history does not drive your renewal.
Fully insured large group
Generally 101+ eligible employeesRates become experience-sensitive, which means your claims data is negotiable leverage. A transition is a reasonable moment to test the market rather than accept a single replacement quote.
Level-funded
Healthier groups, typically 20+ enrolledA fixed monthly cost with a possible surplus refund if claims run low. Requires underwriting, so it is not guaranteed-issue, and it is worth pricing against fully insured rather than assuming it wins.
CaliforniaChoice (private exchange)
1–100 employees wanting employee choiceMultiple carriers on one bill, with employees choosing their own plan. Relevant here because Health Net remains available through CalChoice for a January 1, 2027 effective date, which can buy a group a full 12-month plan cycle before it has to choose a different carrier.
Four mistakes we're already seeing.
Treating it as a renewal instead of a replacement
A renewal is a rate negotiation. This is a carrier change, which means new ID cards, new networks, new formularies, re-established authorizations, and new payroll deductions. The work is closer to a first-time implementation than an annual renewal.
Waiting for the February date
Health Net stopped writing new commercial group business as of September 1, 2026, and its general agency partners are advising employers to move early. Waiting compresses network verification and employee communication into the same few weeks, and Q1 rate increases may already be in effect.
Letting the cheapest quote decide
The cost of a carrier change is rate plus disruption. Disruption shows up as employees losing a physician, restarting an out-of-pocket maximum, or losing access to a medication — and it lands on HR's desk, not the spreadsheet.
Assuming dental and vision are unaffected
Health Net has said its standalone dental and vision plans and Employer Group Waiver Plans are also part of the commercial group closure, with separate communications to follow. If you have those lines with Health Net, confirm them rather than assuming medical is the whole problem.
What a replacement review looks like with us.
- Your employee roster run against each candidate network, by physician and hospital
- Formulary comparison for medications your employees actually take
- Accumulator exposure identified before an effective date is chosen
- Fully insured, level-funded and CalChoice priced side by side
- Employer and employee contribution modeling your CFO can read
- Implementation, enrollment, and payroll-deduction accuracy on the first payroll
Your employees' deductibles may follow them.
The common assumption is that changing carriers resets everyone to zero. In California group coverage that is often wrong: most carriers operate a prior-carrier deductible credit program, and Health Net documents one of its own. But no carrier applies it automatically, and the filing window is short.
For an employee who has already met a $3,000 deductible, this is the difference between a smooth change and paying twice in one year.
How the credit actually works
- It must be requested. No carrier applies it automatically, and members are not asked whether they want it.
- Proof is required — Explanation of Benefits statements per member, or an itemized accumulator report from the prior carrier. Family totals are generally not accepted.
- There is a filing window, commonly 30 to 90 days from the new effective date depending on the carrier.
- Most carriers credit the medical deductible only. Out-of-pocket maximum accumulations are usually NOT credited, and prescription deductibles often are not either.
- Plan type generally has to match — HMO to HMO, PPO to PPO, HDHP to HDHP.
- Only members enrolled with the prior carrier as of the takeover date qualify. New hires afterward do not.
- Credit is usually capped at the new plan's deductible, and only counts accumulations from the current calendar year.
Credit rules vary by carrier and by plan. Confirm the specifics with your replacement carrier in writing before you set an effective date.
Questions employers are asking now.
What are the alternatives to Health Net for California employers?
California has one of the most competitive group medical markets in the country, with multiple statewide carriers plus strong regional plans, and employers can also consider level-funded arrangements or the CaliforniaChoice private exchange. Which options are actually available to a specific employer depends on county, group size, employee participation, and carrier underwriting rules, so the right approach is to market the group rather than assume a single replacement.
When does Health Net group coverage actually end?
Most affected California commercial group policies end February 28, 2027, or as otherwise permitted by the applicable contract and regulatory requirements. Health Net gave each group its specific sunset date in the notice it began mailing on September 1, 2026, so employers should confirm their own date in writing rather than assuming the default.
Do deductibles transfer to a new carrier after Health Net exits?
Not automatically — but usually they can be carried over if you ask in time. Most California group carriers run a prior-carrier deductible credit program, and Health Net documents one itself. The credit has to be requested with Explanation of Benefits statements or an itemized prior-carrier accumulator report, generally within 30 to 90 days of the new effective date. Common limits: the plan type has to match, only members enrolled as of the takeover date qualify, credit is capped at the new plan's deductible, and out-of-pocket maximum and prescription deductible accumulations are usually excluded. Because a February 28, 2027 end date leaves most groups mid-plan-year, identify which employees have meaningful year-to-date spend before you pick an effective date, and confirm the credit rules with the replacement carrier in writing.
Should a California employer switch before its renewal?
Often yes. Health Net stopped accepting new commercial group business as of September 1, 2026, and moving earlier gives an employer more time to verify provider networks, re-establish prior authorizations, and communicate changes to employees. Moving early may also secure rates ahead of Q1 increases, though the trade-off depends on the group's current rate and renewal date.
Is switching carriers cheaper than staying with Health Net?
Staying is not an option for affected plans, so the real comparison is between replacement carriers. In the California small-group market every carrier files identical rates with every broker, which means the savings come from plan design, network selection, and contribution strategy rather than from finding a cheaper quote for the same plan.
