What Happens to Health Coverage When an Employee Leaves Your Plan

One of your team members is leaving — retiring, moving on, or transitioning out of your group plan. Before they go, they need to know what comes next. This page walks through their options clearly, so you can point them in the right direction and they can act before a coverage gap opens.

The Referral Moment Most Employers Don't Know They Can Own

When an employee leaves your group plan, they're suddenly navigating a coverage decision on their own — often for the first time in years. Most don't know the deadlines, the cost differences, or which option actually fits their situation. As their employer, you can make that transition easier with one referral.

 

I work with business clients across Northeast Ohio and beyond, and one of the most common calls I get is from an owner or executive director who says, "I have someone retiring next month — what do I tell them?" The answer is straightforward: send them my way. A single conversation covers their options at no cost to them or to you.

The Four Paths After Losing Job-Based Coverage

When employer-sponsored health insurance ends, most people have four realistic options. The right one depends on age, income, household size, and how quickly coverage needs to start. Here is what each path looks like.

1

COBRA Continuation Coverage

COBRA allows a departing employee to stay on the employer's existing group plan for up to 18 months. The coverage is identical — same network, same benefits — but the employee now pays the full premium, including the share the employer was covering. For someone with ongoing care or a preferred provider, COBRA can be worth the cost. For someone healthy and budget-conscious, it often isn't.

2

Ohio Mini-COBRA

Ohio's mini-COBRA law extends similar continuation rights to employees of smaller employers — those with fewer than 20 employees — who aren't covered under federal COBRA. The continuation period is shorter, typically up to 12 months, but the mechanics are the same: the departing employee retains their existing coverage by paying the full premium. If your business has a small team and an employee is leaving, this is the Ohio-specific option worth knowing.

3

ACA Marketplace Special Enrollment Period

Losing job-based coverage qualifies most people for a Special Enrollment Period on the ACA Marketplace. The window is 60 days from the date coverage ends — not the date employment ends. Missing that window means waiting until the next Open Enrollment period, which could mean months without coverage. Marketplace plans often come with income-based subsidies that make them significantly less expensive than COBRA, and coverage can start as quickly as the first of the following month.

4

Medicare Enrollment After Employment

For employees who are 65 or older and have been relying on employer coverage, leaving a group plan triggers a Special Enrollment Period for Medicare as well. This is a different window and a different process from the ACA Marketplace. Timing matters here too — enrolling outside the correct window can result in permanent late-enrollment penalties on Part B premiums. I handle Medicare referrals regularly through my business client base, and I can connect a retiring employee with the right guidance for their situation.

The 60-Day Window Is the Detail That Changes Everything

The single most important fact for anyone losing job-based coverage: the Special Enrollment Period for ACA Marketplace plans is 60 days from the date coverage ends. Not 90 days. Not whenever it's convenient. Sixty days, and then the window closes.

 

Here is what that means in practice:

 

  • Coverage ends on the last day of the month employment ends, in most cases
  • The 60-day SEP clock starts on that date
  • A Marketplace plan selected during the SEP can start as early as the first of the following month
  • Missing the window means waiting for Open Enrollment — typically November through January — with no subsidized coverage available in between
  • COBRA has its own election window — 60 days from the notice date — but COBRA and a Marketplace plan cannot run simultaneously

 

Passing this timeline to a departing employee before their last day is one of the most useful things an employer can do.

How to Help a Departing Employee Without Taking On the Work Yourself

You don't need to become a benefits expert to support someone leaving your plan. You need one reliable referral. When an employee is retiring, getting laid off, or aging off your group coverage, a quick introduction to Nest gives them a single point of contact who can walk through COBRA costs, Marketplace options, and Medicare eligibility in one conversation.

 

This is a service I provide at no charge to the individual. There is no commission pressure, no enrollment quota, and no obligation. The goal is to make sure your employee lands somewhere with coverage that actually fits — and that they don't miss a deadline because no one told them the clock was running.

What Employers Are Responsible for When Coverage Ends

When an employee leaves your group plan, you have a few specific legal obligations — and they're not complicated, but they do have deadlines. Here's what you're responsible for:

 

  • COBRA election notice: If your group plan is subject to federal COBRA (generally 20 or more employees), you're required to notify the departing employee of their COBRA rights within 14 days of the coverage termination event. Your insurance carrier or plan administrator typically handles the paperwork, but the obligation starts with you.
  • Ohio mini-COBRA notice: If your business has fewer than 20 employees, Ohio law requires you to notify departing employees of their continuation rights under the state's mini-COBRA rules. The notice requirement and timing are similar.
  • Coverage end date confirmation: The employee needs to know exactly when their coverage ends so they can start the clock on their Special Enrollment Period. In most cases, coverage runs through the last day of the month in which employment ends — but confirm this with your carrier, because plan terms vary.
  • Summary of Benefits and Coverage: If requested, you're required to provide plan documents that help the departing employee understand what they had — useful if they're comparing it against Marketplace or COBRA options.

 

What you're not responsible for is helping them choose what comes next. That's where a referral to Nest makes the transition cleaner for everyone. I can take that conversation off your plate entirely.

Frequently Asked Questions

  • How long does COBRA coverage last after leaving a job?

    Federal COBRA continuation coverage lasts up to 18 months in most cases. Ohio mini-COBRA, which applies to smaller employers not covered under federal COBRA, provides up to 12 months of continuation. In both cases, the departing employee pays the full premium — including the portion the employer was previously covering.

  • Is a Marketplace plan cheaper than COBRA?

    It depends on income and household size, but for many people, yes. ACA Marketplace plans come with income-based subsidies — called premium tax credits — that can significantly reduce monthly costs. COBRA preserves your existing coverage but at full cost. Comparing both side by side before making a decision is the right move, and that comparison takes one conversation with a broker.

  • What is the Special Enrollment Period for losing job-based coverage?

    Losing employer-sponsored health insurance qualifies most people for a 60-day Special Enrollment Period on the ACA Marketplace. The window opens on the date coverage ends. Plans selected during an SEP can take effect as early as the first of the following month. Missing the window typically means waiting for Open Enrollment.

  • What happens to Medicare enrollment when someone retires?

    Employees who are 65 or older and have been covered under an employer group plan can enroll in Medicare during a Special Enrollment Period that begins when employment or employer coverage ends, whichever comes first. This window lasts eight months. Enrolling outside this period can result in permanent late-enrollment penalties on Medicare Part B premiums.

  • Does losing employer coverage affect my dependents too?

    Yes. Spouses and dependents covered under the group plan lose coverage at the same time the employee does. They are typically eligible for the same continuation and Marketplace options, and the same 60-day SEP window applies to the entire household.

  • Can an employer in Ohio refer a departing employee to a broker at no cost?

    Yes. Referring a departing employee to an independent broker like Nest costs nothing — for the employer or the employee. The broker's compensation comes from the insurer on any plan that's ultimately selected. The value to the employer is that a trusted resource handles the transition conversation, the employee gets clear guidance on their options, and no one misses a deadline because the information wasn't there.
