What Is COBRA Health Insurance? Election Rights, Costs, Coverage Gaps, and Alternatives

COBRA — the Consolidated Omnibus Budget Reconciliation Act — is a federal law that gives workers and their families the right to continue their employer-sponsored group health insurance after certain events that would otherwise end their coverage. COBRA continuation coverage is a critical safety net, but it comes with significant cost implications and time limitations that every departing employee should understand.

What Events Trigger COBRA Eligibility?

COBRA rights are triggered by what the law calls "qualifying events." Common qualifying events for employees include:

• Voluntary or involuntary job loss (for reasons other than gross misconduct)
• Reduction in hours that causes loss of eligibility for employer health benefits
• Retirement

Qualifying events that give COBRA rights to spouses and dependents include:

• The covered employee's qualifying event (above)
• Divorce or legal separation from the covered employee
• Death of the covered employee
• The employee becomes enrolled in Medicare
• A dependent child aging out of the plan (typically at age 26 under the ACA)

How Long Does COBRA Coverage Last?

The duration of COBRA continuation coverage depends on the qualifying event:

• 18 months for employees and their covered dependents following job loss or reduction in hours
• 29 months if the qualified beneficiary was determined to be disabled by Social Security within 60 days of the qualifying event
• 36 months for dependents who lose coverage due to divorce, separation, death of the employee, Medicare enrollment, or aging out

COBRA can be terminated early if you fail to pay premiums, become covered under another group health plan, or enroll in Medicare.

Which Employers Must Offer COBRA?

COBRA applies to private-sector employers with 20 or more employees, as well as state and local government employers. Church plans and federal government plans are generally exempt from COBRA, though the Federal Employees Health Benefits program has its own continuation coverage rules.

If your employer has fewer than 20 employees, check whether your state has a "mini-COBRA" law. Many states extend similar continuation coverage rights to employees of smaller employers, sometimes for shorter durations.

How Much Does COBRA Cost?

This is where COBRA's limitations become stark. When you are employed, your employer typically covers a significant portion of your health insurance premium — often 70–80% for individual coverage. Under COBRA, you pay the full premium plus a 2% administrative fee. That means if your total plan premium was $600/month (and you only paid $100), under COBRA you would pay $612/month.

For family coverage, COBRA costs can easily exceed $2,000–$2,500 per month. Many former employees cannot sustain these costs, which is why COBRA is often a temporary bridge rather than a long-term solution.

The COBRA Election Timeline

When a qualifying event occurs, your employer must notify the plan administrator within 30 days. The plan administrator then has 14 days to send you an election notice with information about your coverage, the cost, and your election deadline.

You have 60 days from the later of (a) the date coverage was lost, or (b) the date you received the election notice to elect COBRA. This deadline is firm under federal law — missing it means you lose your COBRA rights entirely.

If you elect COBRA, coverage is retroactive to the date it would have been lost, so there is no gap even if you did not immediately elect. However, you will owe premiums back to that date.

COBRA Premium Payment Rules

Once enrolled, your first premium payment is due 45 days after you elect coverage. Subsequent payments are due monthly, typically with a 30-day grace period. Missing a payment after the grace period terminates your COBRA coverage.

Common COBRA Problems and How to Address Them

Failure to send timely election notice. If your employer or plan administrator failed to send a COBRA election notice within the required 30+14 day window, you may have extended time to elect coverage or grounds to pursue the plan for coverage losses. Document when you left employment and when you received the notice.

Incorrect premium amount. Your COBRA premium should equal 102% of the total plan premium (your share plus the employer's share). If you are being charged more, request a breakdown of the premium calculation.

Claims denied during the retroactive election window. If you received care before electing COBRA (during the 60-day election window), those claims should be covered retroactively once you elect and pay premiums back to the start date. If your insurer denies these retroactive claims, appeal citing COBRA's retroactivity provisions.

Coverage terminated without proper notice. If your COBRA was terminated (for missed payment, for example), the insurer must provide notice. Review termination notices carefully.

COBRA Alternatives Worth Considering

Before defaulting to COBRA, compare it to:

• ACA marketplace special enrollment: Job loss triggers a special enrollment period (60 days) for marketplace plans. Depending on your income, you may qualify for premium tax credits that make marketplace coverage far cheaper than COBRA.
• Medicaid: If your income has dropped significantly, you may be eligible for Medicaid, which often has no premiums.
• Spouse or domestic partner's plan: Job loss generally triggers a special enrollment period for a spouse's employer plan.

Fight Back With ClaimBack

If your employer failed to provide timely COBRA notice, your claims were denied during a COBRA election window, or your coverage was improperly terminated, you have appeal rights. ClaimBack helps you document and pursue those claims.
