How to Explain COBRA Continuation Coverage to Employer Clients and Departing Employees
COBRA continuation coverage under ERISA §§601–608 and IRC §4980B allows qualified beneficiaries — employees, spouses, and dependent children — to continue group health plan coverage after a qualifying event that would otherwise cause coverage to end. The employer pays nothing for this continuation beyond administration; the qualified beneficiary pays up to 102% of the full cost of coverage. For insurance brokers, COBRA is not a passive compliance topic — it is an active service obligation. Employers covered by the law face civil penalties of $110 per day per qualified beneficiary for late or defective election notices under ERISA §502(c)(1), plus IRS excise taxes of $100 per day per affected individual under IRC §4980B. Most of those penalties originate from brokers who did not build COBRA notice workflows into their client service model. This guide covers every component of COBRA a broker must understand to keep employer clients compliant and departing employees properly informed.
Prerequisites
- Confirmation that the employer's group health plan is subject to COBRA: applies to private-sector employers with 20 or more employees on more than 50% of typical business days in the prior calendar year (ERISA §601(b); 29 CFR §2590.701-2)
- The plan's current Summary Plan Description (SPD) and COBRA notice templates — the DOL publishes model notices at dol.gov/agencies/ebsa that satisfy the content requirements under 29 CFR §2590.606-4
- Contact information for the plan administrator of record (typically the employer under ERISA §3(16)), the TPA, and the carrier — each has independent notice obligations in the COBRA chain
- A qualifying event log or HR workflow that captures event dates, notice dates, and election outcomes — the penalty clock starts at the qualifying event date, not when HR gets around to processing the separation
Step 1: Identify Qualifying Events and Covered Plans
COBRA applies to group health plans — medical, dental, and vision — maintained by covered employers. Health FSAs are generally covered unless they qualify as excepted benefits (the FSA must not provide more benefit than the maximum COBRA premium, typically satisfied when employee contributions fund the FSA and the employer adds nothing). Life insurance, disability coverage, and standalone disease-specific plans are not subject to COBRA.
Qualifying events by beneficiary category (ERISA §603; 29 CFR §2590.606-4):
For the covered employee:
- Voluntary or involuntary termination of employment — for any reason except gross misconduct. An employee terminated for cause still qualifies unless the employer can demonstrate gross misconduct under the legal standard, which courts interpret narrowly.
- Reduction in hours below the employer's eligibility threshold for group health coverage
For the spouse and dependent children:
- Any of the above employee events
- Employee's death
- Employee becomes entitled to Medicare (Part A or Part B)
- Divorce or legal separation from the covered employee
- Dependent child ceases to qualify as a dependent under plan terms (typically age 26 under ACA §2714, or younger if the plan document sets a lower threshold)
Small employer exception: Employers with fewer than 20 employees on more than 50% of typical business days in the prior year are not subject to federal COBRA. Most states have "mini-COBRA" laws extending continuation requirements to smaller employers — coverage periods and procedures vary by state. Brokers working with sub-20-employee clients must verify the applicable state statute.
Church plans and government plans: Federal COBRA does not apply to church plans (ERISA §4(b)(2)) or government plans (ERISA §4(b)(1)). Many government employers provide continuation coverage under the Public Health Service Act. Church plans are generally not required to provide continuation coverage under federal law.
Step 2: Confirm the Employer's Notice Obligations and Deadlines
COBRA notice compliance is deadline-driven, and the deadlines run from the qualifying event date — not from the date HR processes the separation or notifies the broker. Every covered employer needs a documented workflow that captures qualifying events and triggers notices within the statutory windows.
The notice chain has three components:
Initial (General) Notice — The plan administrator must furnish a general COBRA notice to each covered employee and their spouse within 90 days of coverage commencement under 29 CFR §2590.606-1. This is typically delivered with the SPD at enrollment. It describes the right to elect continuation coverage and identifies who to contact if a qualifying event occurs.
Employer-to-Plan-Administrator Notice — When a qualifying event involves employee termination, reduction in hours, death, or Medicare entitlement, the employer must notify the plan administrator within 30 days of the qualifying event (ERISA §606(a)(2)). For self-funded plans where the employer is also the plan administrator, this step is internal.
Qualified Beneficiary-to-Plan-Administrator Notice — For qualifying events within the qualified beneficiary's knowledge (divorce, legal separation, or a dependent child's loss of eligibility), the qualified beneficiary must notify the plan administrator within 60 days of the qualifying event (ERISA §606(a)(3)). The plan must establish a reasonable notice procedure and include it in the SPD.
Election Notice — Once the plan administrator receives notice of a qualifying event, it must send an election notice to each qualified beneficiary within 14 days (29 CFR §2590.606-4(b)(2)).
Election Period — Qualified beneficiaries have 60 days from the later of (1) coverage loss date or (2) election notice date to elect COBRA (ERISA §605). The 60-day window is a statutory floor — the plan may allow a longer period.
First Premium Payment — After electing, the qualified beneficiary has 45 days from the election date to submit the first premium payment (29 CFR §2590.606-4(b)(2)(iii)). If payment is not made within 45 days, the election is void. Subsequent monthly premiums have a 30-day grace period.
Important: Coverage, once elected and first premium paid, is retroactive to the date of coverage loss — meaning a beneficiary can elect COBRA after a medical claim incurred during the election window and have it covered. Employers who attempt to discourage retroactive election are in violation of ERISA.
Step 3: Calculate the Correct COBRA Premium
The maximum COBRA premium is 102% of the applicable premium — the full cost of coverage for similarly situated active employees under the plan, including both the employer's contribution and the employee's share, plus a 2% administrative charge (ERISA §604; 29 CFR §2590.604-1).
For self-funded plans, the applicable premium is determined annually using either the actuarial cost method or the past-cost method under 26 CFR §54.4980B-8. Most self-funded employers use the past-cost method: prior-year claims costs per covered life, adjusted upward by no more than 2% annually for trend. For the full regulatory comparison between self-funded and fully insured funding arrangements — including how each structure handles premium tax, stop-loss mechanics, and plan design flexibility — see Fully Insured vs Self-Funded Health Plans: Which Structure Fits Your Employer Clients?.
Disability extension premium: If a qualified beneficiary is disabled at the time of the qualifying event and Social Security issues a disability determination within the first 60 days of COBRA coverage, the continuation period extends from 18 months to 29 months. During months 19–29, the maximum premium increases to 150% of the applicable premium (ERISA §607(3)).
What to communicate to departing employees: Most experience sticker shock — the full monthly premium for employer-sponsored family coverage averaged $2,065 per month in 2023 (Kaiser Family Foundation Employer Health Benefits Survey, 2023). Employees accustomed to paying $400–$600/month as their employee share are unprepared for the full cost. Brokers who proactively explain this before termination — and provide the ACA marketplace alternative analysis in Step 5 — reduce disputes and late election problems.
Step 4: Explain Coverage Duration by Qualifying Event
COBRA coverage duration is not uniform — it depends on the nature of the qualifying event:
| Qualifying Event | Maximum Continuation Period |
|---|---|
| Employee termination or reduction in hours | 18 months |
| Employee termination/reduced hours + disability at qualifying event | 29 months (disability extension) |
| Employee's death | 36 months |
| Employee's Medicare entitlement | 36 months |
| Divorce or legal separation | 36 months |
| Dependent child loses dependent status | 36 months |
| Second qualifying event during 18-month period | Up to 36 months total |
Second qualifying event rule: If a qualified beneficiary is already receiving COBRA continuation (for an 18-month event) and a second qualifying event occurs — for example, the employee dies or the employee and spouse divorce — covered spouses and dependent children may extend their coverage to a total of 36 months from the original qualifying event date (ERISA §605(b)).
Early termination: COBRA coverage terminates before the maximum period when:
- The qualified beneficiary fails to pay a required premium within the 30-day grace period
- The employer ceases to maintain any group health plan
- The qualified beneficiary becomes covered under another group health plan that does not impose a pre-existing condition exclusion applicable to a condition the beneficiary has
- The qualified beneficiary becomes entitled to Medicare
Step 5: Compare COBRA to ACA Marketplace Alternatives
Every departing employee who is considering COBRA needs to understand the marketplace alternative. Loss of job-based coverage is a qualifying life event triggering a 60-day special enrollment period for ACA marketplace plans under 45 CFR §155.420(d)(1). The clock runs from the date of coverage loss — so an employee who elects COBRA and later drops it also triggers a 60-day marketplace enrollment window when COBRA coverage ends.
Key comparison framework for departing employees:
| Factor | COBRA | ACA Marketplace |
|---|---|---|
| Plan continuity | Same plan, same network, same providers | New plan selection; network may differ |
| Monthly premium | Up to 102% of full cost (often $1,500–$2,500+/month for family) | Income-based subsidies available under IRC §36B; may be substantially lower |
| Income subsidy | None | Available for household income 100%–400% of federal poverty level |
| Coverage start | Retroactive to date of loss (if elected within 60-day window) | First of the month following plan selection |
| HSA compatibility | COBRA coverage on an HDHP remains HSA-compatible | Depends on the specific marketplace plan selected |
When COBRA is the right choice: Employees with ongoing treatment in progress — chemotherapy, scheduled surgery, complex specialist relationships — employees with HDHP/HSA arrangements who want to maintain HSA contribution eligibility, and employees who expect to return to employer-sponsored coverage within 18 months.
When the marketplace is typically better: Employees with income below 400% of the federal poverty level who qualify for substantial premium tax credits, younger and healthier employees with no ongoing care relationships who can tolerate a network change, and employees in states with robust marketplace plan options.

Step 6: Document Employer Obligations and Define Your Service Scope
Brokers who service employer health plans should establish in writing, at engagement, exactly which COBRA administrative functions they are performing versus which the employer or TPA retains. ERISA §502(c)(1) penalties accrue against the plan administrator — which is the employer absent a written agreement to the contrary. Brokers who informally handle COBRA notices without a written service agreement may face E&O exposure when a notice is late and the employer claims it delegated the obligation.
What brokers typically do: Provide COBRA-compliant election notice templates, train HR on triggering events and notice timelines, review TPA agreements to confirm COBRA administration is covered, and advise on premium calculation methodology.
What the employer must do regardless: Maintain qualifying event records with dates, ensure the designated plan administrator sends timely election notices, collect and remit premiums, and maintain coverage through the election period.
Audit documentation to recommend clients maintain:
- Qualifying event log: event date, event type, employee name, plan administrator notified date, election notice sent date, election received date (if any), first premium received date
- Copies of all election notices sent, with proof of delivery (USPS certificate of mailing or certified mail)
- Premium payment records for each electing beneficiary

Common Mistakes
Mistake 1: Starting the notice clock at HR processing, not the qualifying event. The 30-day employer notice window begins on the qualifying event date — the last day of employment, not the date the separation paperwork is completed or the broker is notified. A termination processed a week late still starts the penalty clock on the actual last day of work.
Mistake 2: Omitting dental and vision from COBRA election notices. If the employer offers standalone dental or vision plans, qualified beneficiaries must be offered COBRA continuation on those plans independently. Brokers who send a medical-only election notice and omit dental and vision create the same $110/day penalty exposure per excluded plan.
Mistake 3: Treating gross misconduct as a blanket termination exception. Courts and the DOL interpret "gross misconduct" narrowly — it requires intentional, willful behavior substantially more egregious than ordinary poor performance or insubordination. Brokers should advise clients not to deny COBRA on gross misconduct grounds without a written legal opinion on the specific facts.
Mistake 4: Allowing the retroactive election window to close before the employee decides. Employees sometimes wait to see if they have a claim before electing. COBRA permits this — a beneficiary can elect within 60 days even if no claim has occurred yet. Brokers who communicate that the window is shorter than 60 days, or who pressure early decisions, create liability.
Mistake 5: Failing to identify mini-COBRA obligations for small employers. Brokers serving employers with 2–19 employees must check the applicable state's continuation coverage law. California, New York, and most other states have mini-COBRA statutes with their own timelines, procedures, and duration rules that may differ from federal COBRA.
Frequently Asked Questions
Does COBRA apply to employers with fewer than 20 employees?
Federal COBRA applies only to employers with 20 or more employees on more than 50% of typical business days in the prior year (ERISA §601(b)). Smaller employers are not subject to federal COBRA, but most states have enacted "mini-COBRA" laws requiring comparable continuation coverage. Timelines and procedures under state mini-COBRA vary — brokers should verify the applicable state statute for each small-employer client.
Can an employee elect COBRA after a medical claim occurs during the election period?
Yes. COBRA coverage, once elected and first premium paid, is retroactive to the date of coverage loss. An employee who incurred a claim on day 45 of the 60-day election window can elect COBRA and have that claim covered. Employers cannot discourage retroactive election or deny claims incurred during the election window.
What happens to COBRA if the employer goes out of business?
If the employer ceases to maintain any group health plan, COBRA coverage terminates — a statutory early termination event under ERISA §605(b)(4). Qualified beneficiaries in this situation become eligible for a 60-day special enrollment period on the ACA marketplace. Brokers should document this event clearly and assist affected former employees with marketplace enrollment.
Is COBRA required for health FSAs?
Health FSAs are subject to COBRA only if the FSA is not an excepted benefit. An FSA qualifies as an excepted benefit — and is exempt from COBRA — when the maximum benefit does not exceed two times the employee's salary reduction election, or $500 plus the salary reduction election if greater. In most practical situations, employee-funded FSAs at standard limits are excepted benefits not subject to COBRA.
What is the COBRA election notice required to contain?
Under 29 CFR §2590.606-4(b)(4), the election notice must identify the qualifying event, name each qualified beneficiary, state the maximum coverage period, state the premium amount and due date, describe the election procedure, and include information about conversion rights if the plan offers them. The DOL's model election notice, available at dol.gov/agencies/ebsa, satisfies these requirements when completed accurately.
How does COBRA interact with the ACA employer mandate?
COBRA coverage counts as minimum essential coverage for former employees receiving it — but the ACA employer mandate under IRC §4980H applies to active full-time employees, not qualified beneficiaries on continuation coverage. A former employee on COBRA is not counted as an active full-time employee for ACA mandate purposes. For the full ACA employer mandate mechanics, including FTE counting and §4980H penalty structure, see ACA Employer Mandate: The 50-Employee Threshold, Coverage Requirements, and Penalties Explained.
Can an employer subsidize COBRA premiums for departing employees?
Yes. The 102% cap is a ceiling — employers may charge less, cover a portion through a severance arrangement, or pay the full premium. Premium subsidies for former employees are generally deductible as ordinary business expenses under IRC §162. If structured as part of a separation agreement, the terms should be documented in writing and coordinated with employment counsel to avoid recharacterization.
What is the state continuation coverage period in California?
California's Cal-COBRA (California Insurance Code §§10128–10128.59) extends continuation coverage for employees of small employers with 2–19 employees for up to 36 months. Employees already on federal COBRA who exhaust the 18-month federal period may be eligible to convert to Cal-COBRA for an additional period. Cal-COBRA applies to fully insured plans regulated by the California Department of Insurance; self-funded plans follow federal law only.
