Health insurance explainer illustration for comparing COBRA and ACA Marketplace coverage after leaving a job — Leaving a job can change health insurance, but different coverage routes have different costs, deadlines and provider networks.

US health insurance guide, November 2026. Plan rules, eligibility, financial help and enrollment deadlines depend on individual circumstances, plan documents and current law. Confirm details with official agencies.

Job loss or a voluntary departure can create two urgent questions: how long will health coverage last, and what will new coverage actually cost? The answer may involve COBRA continuation, an Affordable Care Act Marketplace plan, a spouse’s employer plan, Medicaid or another eligible route. Choosing solely by the headline monthly premium can be a mistake when prescriptions, deductibles, provider networks and enrollment deadlines also matter.

This guide explains how to compare options after leaving a US job. It does not assume that everyone qualifies for the same coverage or that a Marketplace policy will always be cheaper than COBRA. A person in the middle of cancer treatment may reasonably prioritize continuity of care, while another household may prioritize a lower monthly premium and a different provider network. The useful answer comes from comparing the complete cost and actual enrollment rights.

1. First confirm the end date of your current coverage

Employer health insurance does not always end on the exact last day of employment. Some employers keep coverage through the end of the month; others follow different plan terms. Do not infer the date from a coworker’s experience. Ask the benefits administrator for the written coverage termination date, the COBRA election materials if applicable, and details of any coverage for dependents.

Make a short schedule. Record the last covered day, the date your employer or plan administrator sends continuation information, any COBRA election deadline, Marketplace enrollment dates, the first premium due for new coverage, and dates of upcoming medical appointments. Losing the ability to schedule care or fill a prescription can be as disruptive as the premium itself.

For specific federal continuation information, see the US Department of Labor’s COBRA resources. Some state continuation laws differ from federal COBRA and may apply when federal rules do not; state insurance departments can explain local requirements.

2. What COBRA continuation generally does

COBRA can allow eligible workers and family members to continue coverage under the same group health plan for a limited period after a qualifying event, subject to federal requirements. It is not a new insurer or automatically a subsidy program. Keeping substantially the same group coverage can be especially valuable when you already have specialists, current prescriptions or cost-sharing progress during the plan year.

The cost can be surprising because an employer often stops paying its usual portion of the premium. A qualified beneficiary may generally be required to pay up to 102% of the total plan cost for many ordinary COBRA continuation periods; different rules can apply in particular circumstances. The “total cost” is not simply what used to appear as a payroll deduction. If the employer paid most of the premium, the employee’s out-of-pocket monthly amount can rise sharply.

COBRA does not last forever. Under federal rules, job loss or reduced hours commonly makes an 18-month maximum continuation period available to qualifying beneficiaries, with certain exceptions and extensions. Other qualifying events can have different periods. Eligibility also depends on employer and plan circumstances. Read the actual election notice rather than treating the common 18-month rule as a universal guarantee.

3. What a Marketplace special enrollment period means

Losing qualifying job-based health coverage can trigger a Special Enrollment Period for a Marketplace health plan outside the ordinary annual open enrollment period. The precise window and proof requirements matter. Healthcare.gov describes commonly applicable timing, including being able to enroll within a period around the loss of coverage; verify the dates currently presented for your state and situation at HealthCare.gov’s job-based coverage guidance.

A Marketplace policy may have different doctors, drug formularies, deductibles and out-of-pocket maximums from the employer plan. Financial assistance, if available, depends on income and other eligibility factors, and the rules can change. Do not rely on an online article written under older subsidy rules to predict your 2026 or 2027 monthly premium. Use the official application or current plan comparison tool for the correct year.

Marketplace enrollment is not identical to COBRA election. You do not necessarily need to elect COBRA first in order to consider a Marketplace policy after losing eligible coverage. But voluntarily dropping COBRA later does not always create another Marketplace enrollment opportunity. Check before cancelling anything, especially if there is no open enrollment period available.

4. Compare coverage using annual total cost, not premium alone

Start with a realistic estimate of monthly premiums multiplied by the number of months you expect to need that option. Then evaluate deductibles, copays, coinsurance, maximum out-of-pocket exposure, covered prescriptions and network participation. A plan with a lower premium can be more expensive for someone who needs frequent specialist care or expensive drugs. A richer plan can be wasteful for someone who cannot afford its premium even if its cost-sharing is attractive.

Consider a fictional example. Plan A costs $750 per month and has a $2,000 deductible; Plan B costs $360 per month with a $5,500 deductible. Over six months, the premium difference is $2,340. That difference matters, but it does not settle the choice: the drugs and services you expect to use, how the plans count costs, whether deductible credit carries over, and the doctors available could change the total.

Ask for the Summary of Benefits and Coverage and use the plan’s network and formulary lookup. Confirm important information directly with the insurer, especially if a provider’s office says merely that it “accepts” a carrier. A carrier may offer several networks under the same brand, and a clinician participating in one is not necessarily in another.

5. Think about your deductible progress

If you have already paid a substantial part of the annual deductible and out-of-pocket maximum, continuation of the current plan may be more attractive than starting a different policy that resets cost-sharing. However, do not assume amounts always carry over unchanged after a coverage transition. Confirm with the group plan administrator what will count toward current plan-year limits under COBRA.

For a new Marketplace plan, the deductible and cost-sharing rules follow the new policy. Even if the insurer name is the same, the plan design can differ. A careful comparison includes actual deductible remaining, expected services before year-end and whether the plans use the same pharmacies and specialists. Complex care requires an individualized check rather than a generic recommendation.

If someone in the family is pregnant or receiving ongoing treatment, ask about continuity-of-care rules and whether the new insurer offers transition arrangements. Do not cancel existing coverage based solely on a website showing a familiar provider name until the new effective date and network status have been confirmed.

6. Consider your household’s other coverage routes

A spouse’s employer-sponsored plan may offer special enrollment after loss of other coverage. Rules and deadlines are plan-specific and may reflect federal benefits law. The effective date, dependent eligibility and employee premium contribution should be compared with COBRA and Marketplace options. The existing employer may also require documentation of the loss of coverage.

Medicaid and the Children’s Health Insurance Program can be options for eligible people and families, depending on income, state, household characteristics and other rules. Marketplace applications may help assess eligibility or direct you to the relevant state program. Do not assume that someone who recently earned a higher salary is categorically ineligible after job loss; household circumstances and state requirements matter.

For Medicare-eligible people, coordination among employer coverage, COBRA and Medicare raises additional timing and penalty questions. COBRA generally should not be casually treated as identical to current-employment-based coverage for Medicare enrollment decisions. Contact Medicare or qualified benefits assistance before deciding whether to delay enrollment.

7. What happens if you need care during a transition?

Coverage gaps can have serious consequences for people who need medications, specialist visits or unexpected emergency services. Review exact effective dates rather than assuming that enrolling today makes coverage active immediately. For COBRA, election and payment timing may affect how continuation coverage applies, but retroactive coverage rules and claims processing should be verified with the administrator.

If you have an upcoming appointment, call the provider’s billing office and the current or prospective insurer. Ask whether the relevant service is covered, whether prior authorization is required and how claims should be submitted during a transition. Keep written confirmation when possible. Never assume a preauthorization from one plan automatically transfers to a different insurer or policy.

Prescriptions deserve separate attention. Review brand-name and generic coverage, specialty pharmacy restrictions, refill timing and any required step therapy. A plan that looks comparable on general benefits may handle a critical medication differently. The cost of a single uncovered prescription can outweigh several months of premium savings.

8. Avoid the election and cancellation traps

One mistake is waiting to think about insurance until the previous plan has already ended. Another is electing COBRA, later finding it expensive and cancelling without first confirming that a new plan can start. A third is assuming subsidies will be calculated from the last paycheck rather than from the income figure required under current program rules.

Create a simple decision checklist: confirm coverage end date; collect COBRA cost and election notice; investigate spouse’s benefits; obtain official Marketplace quotes for the right coverage year; check Medicaid eligibility where relevant; compare the doctors and drugs; confirm new effective date; only then cancel an old option where appropriate. Keep screenshots and official emails in a secure folder.

Be skeptical of unsolicited calls offering a “government health plan” in exchange for card information. Use official exchange pages, your state’s marketplace, benefits administrators and licensed professionals whose credentials you can verify. Sharing personal medical information with an unverified sales site can create privacy risks.

9. Model a realistic six-month gap between jobs

Imagine a household expecting six months before the next employer plan. They have two options with materially different premiums and cost-sharing. Instead of comparing only month one, use a worksheet with the full six-month premiums, predictable prescriptions, planned care and a reasonable emergency scenario. Include cash-flow timing: some expenses may be due before severance or unemployment benefits arrive.

Consider that a new job may have a waiting period before group coverage begins. Do not assume the next employer’s health plan will start the same day you accept an offer. If the timeline changes, reassess the coverage end date and the next enrollment opportunity. A decision that was reasonable for a two-month gap can become expensive for a year-long transition.

Estimate costs as ranges rather than false precision. The best-case scenario may involve few medical claims; the high-cost scenario may involve significant eligible services until an out-of-pocket maximum is reached. Premiums are paid regardless of whether you use care. Understanding those scenarios helps avoid buying based on one attractive number.

10. Questions to ask before choosing

Ask the current employer: When does active coverage end? How much is the full continuation premium? Who administers COBRA? What is the election date and payment deadline? Ask the prospective plan: Are my doctors in this exact network? Is my medication covered at my pharmacy? What prior authorizations are required? When does coverage start? Ask yourself: Can I sustain premiums if the job search takes longer? How much cash would I need in a high-medical-cost month?

Also ask whether dependents can make different elections and how family members’ needs differ. One person’s specialist network may be much more important than another’s. Coordination can be complex, so do not assume every family member must make an identical decision without reading the rules.

Frequently asked questions

Is COBRA always more expensive?

It often costs more than the former employee payroll deduction because employer contributions may end. But the correct comparison is with an actual alternative plan’s complete cost, including care and networks.

Can I use the Marketplace after leaving my job?

Loss of eligible job-based coverage can create a Special Enrollment Period. The date, state, evidence and eligibility requirements must be checked on the official Marketplace.

Will my deductible reset if I switch?

A new plan commonly applies its own cost-sharing terms, while continuing the same group plan can preserve plan-year progress under applicable rules. Confirm details with each administrator.
