Losing job-based health coverage can feel manageable right up until a prescription refill gets denied, a surgery gets scheduled, or a child ends up in urgent care. That’s why COBRA mistakes can be so expensive: the coverage gap often shows up at the exact moment someone is counting on insurance the most.
COBRA exists to let many workers and family members keep group health coverage for a limited time after certain life events, including job loss or reduced hours. But the system comes with deadlines, notice rules, premium obligations, and transition issues that are easy to misunderstand. The U.S. Department of Labor explains that COBRA generally applies to group health plans sponsored by employers with 20 or more employees, and qualified individuals may be charged up to 102% of the full cost of coverage.

COBRA problems rarely begin with a dramatic denial. More often, they start with something small: a notice that gets ignored, a mistaken assumption about when employer coverage ends, a late payment, or a belief that another plan can always be picked up later.
That’s where things get risky. COBRA election windows are time-sensitive, Marketplace special enrollment periods are separate, and losing one option does not always preserve the other. According to the Department of Labor, people entitled to elect COBRA generally receive at least 60 days to make that election, measured from the later of the date the election notice is furnished or the date coverage would otherwise be lost.

One of the most common COBRA mistakes is thinking employment and health coverage always end on the same day.
In practice, employer-sponsored coverage often ends at the end of the month, but not always. Some plans terminate coverage on the last day worked, some on the last day of the month, and some on another plan-defined date. That timing matters because it affects when a COBRA election period starts, when bills may be due, and whether a gap already exists.
This is one reason people in transition sometimes get caught off guard. They stop working on March 12, assume they are uninsured on March 13, and rush into decisions. Others assume they are covered through the month, then learn too late that coverage ended earlier.
Here’s what this often means in practical terms:
Some people in this situation find it helpful to compare the plan documents, termination paperwork, and election notice side by side. If any of those dates conflict, an attorney might help determine whether notice or coverage handling created a legal issue.
COBRA can be valuable partly because it may allow retroactive continuation of the same group health coverage after a qualifying event. But that option is tied to a strict election period.
The Department of Labor states that qualified beneficiaries generally get at least 60 days to choose COBRA, starting from the later of the date the election notice is provided or the date coverage would otherwise end. DOL COBRA FAQs
