What COBRA Is — and What It Isn't
COBRA stands for the Consolidated Omnibus Budget Reconciliation Act — federal legislation passed in 1985 that gives workers and their dependents the right to continue employer-sponsored group health coverage for a limited time after certain events that would otherwise end that coverage.
COBRA is not a separate health insurance program and not government-provided coverage. It is the same exact health plan you had while employed — the same network, the same benefits, the same deductibles and out-of-pocket maximums — just paid entirely by you instead of being subsidized by your employer.
A federal right to extend employer-sponsored group health plan coverage for yourself and covered dependents for a temporary period following a qualifying event such as job loss, reduction in hours, divorce, or death of the covered employee. Coverage is identical to what you had while employed. You pay the full premium — both your prior share and the employer's share — plus an administrative fee of up to 2%.
Why COBRA Costs So Much More Than Your Work Plan Did
The sticker shock of COBRA is nearly universal — and understanding why it costs what it does makes the number less alarming, even if no less expensive.
When you were employed, your pay stub showed only your share of the health insurance premium. But your employer was also paying a significant portion — often 70–80% of the total premium for employee-only coverage. You never saw that number because it was never your obligation. Under COBRA, you pay both halves plus an administrative fee. If your employer was paying $600/month and you were paying $150/month, your COBRA premium is up to $765/month. The coverage is identical; the subsidy is gone.
If you know a job change or layoff is coming, ask your HR or benefits department for the full unsubsidized premium for your current plan before your last day. This gives you an accurate COBRA cost estimate immediately — rather than waiting for the formal COBRA notice, which can take up to 44 days after your coverage ends.
Who Is Eligible for COBRA
COBRA applies to group health plans maintained by employers with 20 or more employees. Smaller employers may be subject to "mini-COBRA" laws in some states — similar continuation rights under state law. If your employer has fewer than 20 employees, check whether your state has its own continuation coverage requirement.
Three categories of people can elect COBRA continuation coverage:
- The employee, their spouse, and dependent children who were covered under the group plan at the time of the qualifying event
- Each qualified beneficiary has an independent right to elect COBRA — a dependent can elect even if the employee does not
- A newborn or adopted child added during a COBRA period is also entitled to continuation coverage
Qualifying Events That Trigger COBRA Rights
COBRA rights are triggered by specific events. The duration available depends on which event triggered it.
Events Entitling 18 Months of Continuation
- Voluntary or involuntary job loss — except for gross misconduct
- Reduction in hours that causes loss of health coverage eligibility
Events Entitling 36 Months of Continuation
- Death of the covered employee
- Divorce or legal separation from the covered employee
- Covered employee becomes entitled to Medicare
- Dependent child loses dependent status under the plan (such as aging out)
If you are terminated for gross misconduct, you lose COBRA eligibility. "Gross misconduct" is not precisely defined in the law — its interpretation varies — but serious workplace offenses can result in denial. If you believe you were wrongly denied COBRA on these grounds, the Department of Labor's Employee Benefits Security Administration handles COBRA complaints.
The COBRA Election Timeline
COBRA has specific deadlines with significant consequences for missing them.
- Employer notification: Your employer must notify the plan administrator within 30 days of a qualifying event.
- Notice to you: The plan administrator must send your COBRA election notice within 14 days of being notified — meaning you could wait up to 44 days after coverage ends to receive it.
- Your election window: You have 60 days from the date of the notice (or coverage end date, whichever is later) to elect COBRA. Missing this window permanently eliminates your COBRA right for that qualifying event.
- First premium payment: Once elected, you have 45 days to make your first payment — which is retroactive to your coverage end date.
Because you have 60 days to elect and 45 days after election to pay — and payment is retroactive to your coverage end date — you can wait up to 105 days before committing. If you stay healthy and find other coverage, you decline and pay nothing. If you have a significant medical event during that window, you can elect COBRA retroactively and your claim will be covered. This is not a loophole — it is how the law is designed. Know the deadlines and use them strategically.
What COBRA Covers
COBRA covers the same benefits you had under the employer group plan — medical, dental, and vision if those were included. The network, copays, deductibles, and out-of-pocket maximums remain identical.
Crucially, your deductible and out-of-pocket maximum accumulation carries over. If you met $800 of a $1,500 deductible before losing coverage, you only need to meet the remaining $700 under COBRA within the same plan year. This mid-year continuity is one of COBRA's most significant practical advantages over starting fresh on a new plan.
If you lose coverage late in a calendar year after meeting a significant portion of your deductible, COBRA may provide meaningful near-term value even at its high cost. Switching to a new plan resets your accumulators to zero — all the cost-sharing you've already paid toward your deductible and out-of-pocket maximum starts over.
COBRA Alternatives You Should Know About
COBRA is not your only option — and for many people, it is not the best option.
Marketplace / ACA Plan (Special Enrollment Period)
Losing job-based health insurance triggers a 60-day Special Enrollment Period on the ACA marketplace. You can enroll in a marketplace plan outside of standard open enrollment, and if your income qualifies you for premium tax credits, the cost may be significantly lower than COBRA. This is the most important alternative to evaluate immediately — run the comparison before assuming COBRA is the only path.
Spouse's Employer Plan
Losing your own job-based insurance is a qualifying event that allows a spouse to add you to their employer plan outside of open enrollment. If the spouse's employer subsidizes dependent coverage generously, this is often the least expensive and simplest path.
Medicaid
If your income drops significantly after job loss — particularly in states that expanded Medicaid — you may qualify for Medicaid immediately. Eligibility is based on current monthly income, not annual income, so a job loss can create eligibility even if your prior-year income was substantial.
Short-Term Health Plans
Short-term plans are significantly cheaper but cover far less — they typically exclude pre-existing conditions, mental health services, maternity care, and preventive services. They are not ACA-compliant and should be considered only as a last resort for brief gaps when you're confident you won't need significant care.
COBRA vs. Marketplace Plan: How to Compare
When COBRA Is Actually Worth It
COBRA's high cost means it isn't the right choice for everyone. Here's when it genuinely makes sense:
- You've met a significant portion of your deductible or out-of-pocket maximum and anticipate needing care soon. Starting a new plan resets your accumulators; COBRA preserves your progress.
- You're mid-treatment and your current doctors, hospital, or specialist are in-network under your employer's plan. Switching risks disrupting care if providers aren't in the new network.
- A scheduled procedure is already approved and planned under your current plan.
- Your income is too high to qualify for meaningful ACA subsidies and the marketplace plan premium is comparable to COBRA anyway — in which case the continuity advantage favors COBRA.
- You expect new employer coverage quickly — within 1–3 months — and want continuity rather than onboarding to a new plan briefly.
- You want to preserve the retroactive election option while assessing whether you'll need coverage during the gap.
When COBRA Is Usually Not Worth It
- You're early in the plan year with little deductible accumulation and your income qualifies for meaningful ACA subsidies
- The employment gap is expected to be brief and you're generally healthy
- A spouse's employer plan is available at lower cost with comparable coverage
- Your income after job loss qualifies you for Medicaid
COBRA is expensive because it removes the employer subsidy that made your work plan affordable — not because the coverage is different or better. Whether it's worth the cost depends on your situation: how much deductible credit you've built, whether you have upcoming care, what alternatives are available at your income level, and how long the gap in coverage is likely to be. Always evaluate marketplace plans and subsidy eligibility before defaulting to COBRA. And regardless of what you decide — elect COBRA before the 60-day window closes. You can decline to pay later. You cannot reverse a missed election deadline.
