Losing a job can bring a stack of immediate questions, and health insurance is often near the top of the list. If your medical coverage came through work, COBRA may offer a way to keep that same group health plan for a limited period after employment ends or hours are reduced. For many people, that extra time can create breathing room while they compare options, finish treatment, or avoid a sudden gap in care.
This beginner’s guide walks through the basics in plain English. In this post you’ll learn what COBRA is, who may qualify, how long coverage can last, what it often costs, how election deadlines work, and when another option—like Marketplace coverage—may be worth comparing. If you want a broader overview of the framework behind continuation coverage, premiums, and timing rules, this plain-language overview of how COBRA works after a job change can help round out the picture.

COBRA stands for the Consolidated Omnibus Budget Reconciliation Act. In general terms, it is a federal law that lets certain workers and their families keep group health coverage for a temporary period after a qualifying event would otherwise cause that coverage to end. The U.S. Department of Labor explains that COBRA applies to group health plans maintained by private-sector employers with 20 or more employees and gives qualified beneficiaries the chance to continue coverage that would otherwise be lost. The Centers for Medicare & Medicaid Services and the U.S. Department of Labor both describe COBRA as temporary continuation of existing group health coverage.
That last part matters: COBRA usually keeps the same plan you already had. That can mean the same network, the same deductibles already in progress for the year, the same doctors, and the same prescription coverage terms, subject to the plan’s rules. For someone in the middle of ongoing treatment, pregnancy care, or a complex medication regimen, continuity can be a major reason COBRA stays on the table.
Most nonelderly Americans with private health insurance get it through an employer. Kaiser Family Foundation reported that about 154 million nonelderly Americans rely on employer-sponsored coverage, which helps explain why job loss can quickly become a health coverage problem as well as an income problem. KFF’s employer coverage data shows how widespread this coverage source remains.
That connection is one reason COBRA exists. It can provide a temporary bridge instead of forcing people into an immediate change in doctors, treatment rules, or formularies. In situations involving a sudden layoff, reduced hours, or a family transition, people often look at COBRA first because it may preserve familiar coverage while they sort out the next step.
COBRA usually comes into play when three things line up:
According to CMS, federal COBRA generally applies to private-sector and state and local government group health plans sponsored by employers with 20 or more employees.
A qualifying event often includes:
