Learn How COBRA Health Insurance Works

What COBRA Health Insurance Is and Why It Exists

COBRA stands for the Consolidated Omnibus Budget Reconciliation Act, a federal law passed in 1986. This law created a way for people to keep health insurance coverage from their former employer for a limited time after they lose their job or experience other major life changes. Without COBRA, many workers would have no health insurance between jobs, which could leave them vulnerable to large medical bills.

COBRA is not a new type of insurance plan. Instead, it's a continuation of the same health insurance you had while working. If your employer offered a Blue Cross plan, for example, COBRA lets you keep that exact Blue Cross plan. The coverage remains identical—same doctors, same prescription drugs, same hospital network—but you pay the full cost yourself rather than splitting it with your employer.

The law applies to employers with 20 or more workers. Smaller companies are not required to offer COBRA. This means that people working for small businesses may not have COBRA available to them when they leave their job. Understanding whether your employer falls under COBRA rules is an important first step.

COBRA coverage is temporary, typically lasting 18 months for job loss. In some situations—such as when a spouse or child loses coverage—the period can extend to 36 months. This time window gives workers a runway to find new employment with health benefits or to purchase insurance on their own.

Practical Takeaway: COBRA allows you to continue your current employer health plan after job loss or other qualifying events. It's not new coverage but a continuation of what you had. Check whether your employer has 20+ employees, as this determines whether COBRA is even available to you.

Qualifying Events That Trigger COBRA Rights

COBRA rights are triggered by specific life events. The most common is losing your job through layoff or termination. However, voluntary resignation typically does not trigger COBRA rights—you must lose coverage through no fault of your own. If you quit your job, you generally cannot use COBRA, though some employers may offer it voluntarily in certain situations.

A reduction in work hours that causes you to lose health benefits is another qualifying event. For example, if you worked full-time and your employer cut you to part-time status, removing you from the health plan, COBRA would apply. The key is that you must have lost the health coverage itself, not just experienced a pay reduction.

Family members also have COBRA rights when coverage is lost. If your spouse was covered under your employer plan and you die, your spouse can continue coverage. If your child was on your plan and you die or become divorced, the child may have COBRA rights. A child's loss of coverage when they age out of a parent's plan at age 26 can trigger COBRA for that child.

Employer plan termination is another qualifying event. If your company stops offering health insurance altogether, all covered employees and their families have COBRA rights. This is different from merely changing insurance carriers—the plan itself must end.

Some states have passed "mini-COBRA" laws that cover smaller employers not included in the federal law. These state programs may apply to employers with fewer than 20 employees. The rules vary by state, so people working for small companies should research their state's regulations.

Practical Takeaway: COBRA applies mainly to job loss, reduced hours that end coverage, family events (death, divorce, age limits), and plan termination. Voluntary resignation usually does not qualify. Know which event applies to your situation to understand your rights.

How COBRA Coverage and Costs Work

When you continue coverage under COBRA, you receive the same plan you had as an employee. Nothing changes about the coverage itself. You maintain access to the same doctors, hospitals, prescription drug formularies, and deductibles. The only difference is who pays the premium.

As an employee, your employer typically paid a portion of your premium—often 50 to 80 percent—while you paid the rest through payroll deduction. Under COBRA, you must pay the full employee portion plus the full employer portion. Federal law allows employers to add a 2 percent administrative fee on top of this total. This means COBRA premiums can be significantly higher than what you paid as an employee.

For example, suppose your health plan cost $1,200 per month total. Your employer paid $900, and you paid $300 through payroll deduction. Under COBRA, you would owe approximately $1,200 plus 2 percent ($24), totaling $1,224 per month. This represents a large increase from your previous $300 employee contribution.

COBRA premiums are due monthly, and you must pay them on time to maintain coverage. Missing a payment can result in loss of coverage. Most employers provide a grace period of 30 days, but this varies. After losing coverage, you cannot retroactively reinstate it, so timely payment is essential.

Employers set their own payment methods and deadlines. Some allow online payment, others require checks by mail, and some use automatic bank withdrawals. When you receive your COBRA notice, it will explain the specific payment process your employer uses.

Practical Takeaway: COBRA coverage is identical to your former plan, but you pay both the employee and employer portions of the premium, plus a small administrative fee. Expect premiums to roughly double. Payment must be timely and monthly to keep coverage active.

The COBRA Notice and Election Period

Within 14 days of a qualifying event, your employer must send you a written COBRA notice explaining your rights. This notice is a legal requirement and contains critical information: the cost of coverage, how long coverage lasts, how to pay, and the deadline for making your choice. Read this notice carefully and keep it for your records.

The notice will explain that you have 60 days from the date you lose coverage to decide whether to continue it under COBRA. This 60-day window is your election period. You do not have to decide immediately, but you cannot wait longer than 60 days. Once the deadline passes, you lose the right to COBRA coverage.

The 60-day clock starts on the date your coverage ended, not the date you received the notice. For example, if you lost your job on March 15 and received the COBRA notice on March 20, your election deadline is May 14 (60 days from March 15). This is important because you might not receive the notice immediately after losing coverage.

To elect COBRA, you must respond to your employer in writing using the method specified in the notice. Some employers accept email, others require a signed form by mail. Follow the instructions exactly. Keep a copy of your election for your records. If possible, send it via certified mail so you have proof of delivery.

If you do not respond within 60 days, you lose COBRA rights for that qualifying event. You cannot change your mind later. However, if you experience a second qualifying event—such as a spouse's job loss or a child's birth—you may be entitled to a new COBRA election period for that second event.

Practical Takeaway: You have 60 days from losing coverage to choose COBRA. The employer must notify you in writing. Respond in writing using the method specified, keep proof, and meet the deadline. Missing it means losing COBRA rights permanently.

How Long COBRA Lasts and When It Ends

The length of COBRA coverage depends on the qualifying event. For most people who lose coverage due to job loss or reduced hours, COBRA lasts 18 months. This provides roughly a year and a half to find new employment or purchase other insurance. Eighteen months is the standard period and covers the majority of COBRA cases.

For family members, COBRA coverage can last longer. If you lose coverage because of your spouse's death, divorce, or reduction in hours, you may have COBRA rights for 36 months—three years. If a child loses coverage because of aging out of a parent's plan at age 26, the child also may have 36 months of COBRA rights. These extended periods reflect the greater disruption to family coverage.

COBRA coverage can end before the standard period for several reasons. If you find new employment with health benefits, you can drop COBRA and enroll in your new plan. You do not have to use the full 18 or 36 months. Your new employer's plan likely has an enrollment period
