Losing a job or cutting back to part-time hours in the years before Medicare eligibility can leave an older worker suddenly without health coverage. A federal law known as COBRA offers a bridge: it lets many employees keep the exact group health plan they already had, at least for a while. The catch, and it is a large one, is the price.
What COBRA continuation coverage is
COBRA, short for the Consolidated Omnibus Budget Reconciliation Act, requires many employers to let workers and their families continue the company health plan after coverage would otherwise end. The Department of Labor’s COBRA guidance explains that it generally applies to private employers with 20 or more employees, along with many state and local government plans. The coverage is identical to what the worker had on the job, the same network, benefits, and prescription coverage, so there is no disruption in care or change of doctors. It is a continuation of the existing plan, not a new one, which is exactly why it appeals to someone in the middle of treatment who cannot afford to switch networks.

Who qualifies and the 18-month period
The most common trigger is losing group coverage because a job ends, for reasons other than gross misconduct, or because hours are reduced below the plan’s eligibility threshold. In those cases the worker and covered dependents can generally continue the plan for up to 18 months. Spouses and children who were on the plan qualify in their own right, which matters if a family member needs to keep seeing particular specialists during the gap. Each qualified beneficiary can even elect COBRA independently, so a spouse mid-treatment could continue coverage even if the former employee decides to go elsewhere.
Why the premium jumps to the full cost
The financial shock of COBRA comes from who pays. While employed, most workers see only their share of the premium deducted from a paycheck, because the employer quietly covers the larger portion, often well over half of the true cost. Under COBRA that subsidy disappears. The individual pays the entire premium, both the employee and the former employer’s share, plus an administrative charge of up to 2 percent. A plan that cost a worker a couple hundred dollars a month out of pocket can suddenly cost several times that. To put numbers on it, if a worker paid 250 dollars a month while the employer paid 750, the true premium is 1,000, and under COBRA the former employee owes that full 1,000 plus the 2 percent fee, roughly 1,020 a month. Nothing about the coverage changed; only the person paying for it did.
Longer coverage for certain family events
The 18-month figure is the baseline, but some situations stretch the coverage to 36 months. When the qualifying event is a divorce or legal separation, the death of the covered employee, or a child aging out of dependent status, affected family members can typically continue coverage for up to three years. There is also a limited extension to 29 months when a person is determined to be disabled, which can help someone who is not yet old enough for Medicare and cannot easily obtain other coverage. These longer windows exist because the events behind them, unlike a simple job change, can leave a dependent without any realistic path to replacement coverage.
The election window, deadlines, and alternatives
COBRA runs on strict deadlines. After a qualifying event, the plan must send an election notice, and the individual has a set window, generally 60 days, to choose the coverage. Elected coverage is retroactive to the date the prior coverage ended, so there is no gap, but premiums must be paid on time or the coverage lapses for good. Because the cost is high, COBRA is not always the best option. Someone losing job-based coverage also qualifies for a special enrollment period to buy a plan through the Health Insurance Marketplace, where income-based subsidies may make coverage far cheaper than the full COBRA premium, sometimes dramatically so for a household whose income has just dropped. The federal Marketplace guidance lays out how those choices compare and how the deadlines interact, including the fact that electing COBRA first can complicate a later switch. There is also a timing subtlety worth knowing: a person can use COBRA as a short bridge, keeping the plan for a month or two while a Marketplace policy is lined up, then drop it once the new coverage starts, though switching mid-year outside an open enrollment window depends on qualifying for a special enrollment period. Missing a COBRA premium payment, by contrast, ends the coverage permanently with no second chance, so the deadlines deserve close attention.
For older Americans, the decision often turns on the runway to Medicare. A 63-year-old bridging 18 months to age 65 might use COBRA to keep trusted doctors through an ongoing treatment, while someone with more time or a modest income might find a subsidized Marketplace plan the better value. Either way, the practical point holds: COBRA preserves the familiar plan and prevents a coverage gap, but it does so at the full, unsubsidized cost, so it pays to compare it against the Marketplace before committing to those premiums.
