Meeting this line for the first time? The same evidence, arranged for a first reading: the Employer group health coverage (federal requirements) guide.

Not a policy form so much as a set of federal obligations that attach to one. Two bodies of law do most of the work: the continuation rules that let a person keep group coverage after they would otherwise lose it, and the shared responsibility rules that decide which employers must offer coverage at all. Both are statute, so unlike most lines the governing text can be read in full. A person losing coverage generally has at least 60 days to elect continuation [3], and the plan may charge no more than 102 percent of the applicable premium for it [1].

Who or what it is designed to protect

A covered employee and their qualified beneficiaries against losing group coverage on the date a qualifying event occurs, by giving a right to continue it [1]
A spouse after divorce or legal separation, and a child who ceases to be a dependent, both of which are qualifying events in their own right [2]
A retiree whose former employer enters a title 11 proceeding, which is a qualifying event reaching a substantial elimination of coverage within a year either side of commencement [2]
Not the employer from the obligation. Nothing here is optional for a plan that is subject to it

What it commonly covers

Continuation after termination or reduced hours, for 18 months. Section 1162(2)(A)(i) sets the maximum period at the date which is 18 months after the qualifying event, for a termination or a reduction of hours [1].
Continuation for 36 months after the other qualifying events. Section 1162(2)(A)(iv) sets the maximum at 36 months after the date of the qualifying event for events other than termination or reduction of hours [1].
An extension to 29 months on disability. Where a qualified beneficiary is determined disabled during the first 60 days of continuation and proper notice is given before the 18 months end, the reference to 18 months is deemed a reference to 29 months with respect to all qualified beneficiaries [1].
Six qualifying events, named in the statute. Death of the covered employee; termination other than for gross misconduct, or reduction of hours; divorce or legal separation; the employee becoming entitled to Medicare benefits; a dependent child ceasing to qualify; and a title 11 proceeding with respect to the employer [2].
An election period of at least 60 days. It begins not later than the date coverage terminates by reason of the qualifying event, runs at least 60 days, and ends not earlier than 60 days after the later of that date or the date of the notice under section 1166(4) [3].

What it commonly excludes or limits

Termination for gross misconduct. The qualifying event in section 1163(2) is a termination other than by reason of the employee's gross misconduct, so a termination on that ground is outside the list entirely [2].
Any obligation on the employer to subsidise the continued coverage. The plan may require payment of a premium not exceeding 102 percent of the applicable premium [1]. The right is to keep the coverage, at a cost that now falls on the individual.
A duty on the employer to report the two personal events. For divorce or legal separation and for a child ceasing to be a dependent, the covered employee or qualified beneficiary is responsible for notifying the administrator within 60 days [4]. An employer has no way of knowing about either.
Employers below the applicable large employer threshold, for shared responsibility. The shared responsibility rules apply to an employer who employed an average of at least 50 full-time employees on business days during the preceding calendar year [5].

Limits, deductibles, and conditions

There is no limit structure here in the property sense. The numbers that govern are periods and thresholds.
18 months for a termination or reduction of hours, and 36 months for the other qualifying events [1].
29 months where the disability extension applies, and it applies with respect to all qualified beneficiaries rather than only the disabled one [1].
102 percent of the applicable premium is the ceiling on what the plan may charge, payable in monthly installments at the election of the payor [1].
No premium may be required before the day which is 45 days after the day the qualified beneficiary made the initial election [1].
An average of at least 50 full-time employees over the preceding calendar year makes an employer an applicable large employer, counting part-time hours by dividing aggregate non-full-time hours of service for a month by 120 [5].
Full-time means employed on average at least 30 hours of service per week for the month [5].

Endorsements and connected policies

State continuation, where it applies. Several states extend continuation to employers below the federal threshold or lengthen the federal period. That is state law and is not described by the federal sections cited here.
The plan document and summary plan description. The statutory floor is a floor. A multiemployer plan may provide longer notice periods than the 30 and 14 day defaults, which the statute expressly permits in its own terms [4].

Commonly written alongside: Employee benefits administration generally, where the notice and recordkeeping duties sit, Employment practices liability, which answers claims arising from the employment relationship rather than from the plan, Workers compensation, which answers workplace injury and is not affected by these rules.

What actually goes wrong on this line

Exposures, as distinct from what the policy protects. This is the question an underwriter is asking, and the one to answer before judging a limit.

A notice chain with three links and three clocks
The employer has 30 days to notify the administrator of a death, termination or reduction of hours, Medicare entitlement or title 11 proceeding; the administrator then has 14 days to notify the qualified beneficiary [4]. A delay anywhere in that chain is an exposure for whoever caused it.
The two events nobody tells the employer about
Divorce or legal separation and a child ceasing to be a dependent are reported by the individual within 60 days [4], and they are qualifying events carrying the longer 36 month period [1][2]. Neither is visible from the payroll system.
A late notice that extends rather than forfeits the right
The election period ends not earlier than 60 days after the later of coverage terminating and the notice arriving [3]. Giving notice late does not close the window early; it moves it, and the plan carries the coverage in the meantime.
Becoming an applicable large employer without noticing
The test is an average over the preceding calendar year, and part-time hours count through the divide-by-120 rule [5]. An employer can cross the line without ever having 50 people on the payroll at one time.
Asserting gross misconduct
It is the only conduct-based carve-out in the qualifying event list [2], and treating a termination as outside continuation on that basis decides someone's health coverage on a contested characterisation.

What reduces the frequency or the severity

Things a reader can do, each tied to a published source. None of these is a promise about price: whether an insurer credits any of them is an underwriting decision and is not stated here.

Record the qualifying event date at the time it happens
Every period in these sections runs from it: 18 or 36 months of coverage, 30 days for the employer notice, 14 days for the administrator notice [1][4].
Write down the procedure for the events individuals must report
The statute places divorce, legal separation and a child ceasing to be a dependent on the individual within 60 days [4], so whether anyone knows how to report is a plan administration question rather than a statutory one.
Keep proof of when each notice was sent
Because the election period ends not earlier than 60 days after the later of termination and the notice [3], the notice date is what fixes the deadline, and it is the employer or administrator who has to be able to show it.
Recount the workforce on the statutory basis each year
Average full-time employees over the preceding calendar year, plus non-full-time hours divided by 120, against a full-time test of 30 hours of service per week [5].
Do not require payment inside the 45 day window
No premium may be required before the day which is 45 days after the initial election [1], which matters most to the person who has just lost their income alongside their coverage.

Information an underwriter commonly requests

This is what is usually asked, not a legal requirement and not a promise that supplying it produces an offer.

The average number of full-time employees over the preceding calendar year, which decides applicable large employer status [5]
Aggregate hours of service of employees who are not full-time, since those are converted by dividing by 120 [5]
Whether any employee averages at least 30 hours of service per week, which is the full-time test [5]
Whether the plan is a multiemployer plan, which can lengthen the statutory notice periods [4]
Who administers the plan, since the 14 day notice duty sits on the administrator [4]
Whether written notice procedures exist for the events the individual must report [4]
The date of any qualifying event, since every period in these sections runs from it [2]

State variations

CA. The sections cited here are federal and apply the same way in every state. California and several others add their own continuation requirements on top, including for employers below the federal threshold, and those are state law not described by these records [5].

Office of the Law Revision Counsel, U.S. House of Representatives (uscode.house.gov)Primary lawPrimaryJurisdiction USLast checked September 6, 2026Updates: Amended only by legislation.ID usc-29-1162-continuation-period
What this source supports (5)
Section 1162(2)(A)(i) sets the maximum period of continuation coverage, for a qualifying event that is a termination or reduction of hours, at the date which is 18 months after the date of the qualifying event.
Section 1162(2)(A)(iv) sets the maximum period, for other qualifying events, at the date which is 36 months after the date of the qualifying event.
Section 1162(2)(A)(viii) provides that where a qualified beneficiary is determined to be disabled during the first 60 days of continuation coverage and proper notice is given before the end of the 18 months, any reference in clause (i) or (ii) to 18 months is deemed a reference to 29 months with respect to all qualified beneficiaries.
Section 1162(3) provides that the plan may require payment of a premium for any period of continuation coverage, provided that the premium shall not exceed 102 percent of the applicable premium for that period, and may at the election of the payor be made in monthly installments.
Section 1162(3) provides that in no event may the plan require the payment of any premium before the day which is 45 days after the day on which the qualified beneficiary made the initial election.
The two figures people remember are 18 months and 102 percent, and the two they do not are the ones that decide whether continuation is usable in practice. The 45 day floor in subsection (3) means a person who has just lost coverage is not required to fund it on the day they elect, and the 29 month disability extension in (2)(A)(viii) reaches all qualified beneficiaries rather than only the disabled one. Read alongside sections 1163, 1165 and 1166, which supply the events, the election window and the notice chain that make this section operative.

What this source supports (7)
Section 1163(1) lists the death of the covered employee as a qualifying event.
Section 1163(2) lists the termination, other than by reason of the employee's gross misconduct, or reduction of hours, of the covered employee's employment.
Section 1163(3) lists the divorce or legal separation of the covered employee from the employee's spouse.
Section 1163(4) lists the covered employee becoming entitled to benefits under title XVIII of the Social Security Act.
Section 1163(5) lists a dependent child ceasing to be a dependent child under the generally applicable requirements of the plan.
Section 1163(6) lists a proceeding in a case under title 11, commencing on or after July 1, 1986, with respect to the employer from whose employment the covered employee retired at any time.
Section 1163 provides that in the case of an event described in paragraph (6), a loss of coverage includes a substantial elimination of coverage with respect to a qualified beneficiary described in section 1167(3)(C) within one year before or after the date of commencement of the proceeding.
The gross misconduct carve-out in paragraph (2) is the only conduct-based exclusion in the list, and it is the provision most often asserted and least often defined. Note also that paragraphs (3) and (5), divorce or legal separation and a child ceasing to be a dependent, are the two events the statute makes the individual rather than the employer responsible for reporting, which is why they are the ones most often missed.

What this source supports (3)
Section 1165(a)(1)(A) provides that the election period begins not later than the date on which coverage terminates under the plan by reason of a qualifying event.
Section 1165(a)(1)(B) provides that the election period is of at least 60 days' duration.
Section 1165(a)(1)(C) provides that the election period ends not earlier than 60 days after the later of the date on which coverage terminates by reason of the qualifying event, or, in the case of any qualified beneficiary who receives notice under section 1166(4), the date of that notice.
The election period is measured from the later of coverage ending and the notice arriving, so a late notice moves the deadline rather than shortening the window. That is the practical protection in this section and it is why the notice dates in section 1166 are worth recording at the time.

29 U.S.C. 1166 (who must give notice of a qualifying event, and by when)(opens the original record on Office of the Law Revision Counsel, U.S. House of Representatives (uscode.house.gov))

What this source supports (3)
Section 1166 requires the employer of an employee under a plan to notify the administrator of a qualifying event described in paragraph (1), (2), (4) or (6) of section 1163 within 30 days of the date of the qualifying event, or in the case of a group health plan which is a multiemployer plan such longer period as may be provided in the terms of the plan.
Section 1166 requires the administrator to notify any qualified beneficiary with respect to the event of that beneficiary's rights under the subsection, within 14 days of the date on which the administrator is notified, or in the case of a multiemployer plan such longer period as may be provided in the terms of the plan.
Section 1166 provides that each covered employee or qualified beneficiary is responsible for notifying the administrator of the occurrence of any qualifying event described in paragraph (3) or (5) of section 1163 within 60 days after the date of the qualifying event.
The chain has three links and they run on different clocks: the employer has 30 days to tell the administrator, the administrator has 14 days to tell the beneficiary, and for divorce, legal separation or a child ceasing to be a dependent the duty to report sits on the individual with 60 days. Those two events are the ones an employer has no way of knowing about, which is the reason the statute allocates them differently.

26 U.S.C. 4980H(c) (who is an applicable large employer, and who is a full-time employee)(opens the original record on Office of the Law Revision Counsel, U.S. House of Representatives (uscode.house.gov))
Office of the Law Revision Counsel, U.S. House of Representatives (uscode.house.gov)Primary lawPrimaryJurisdiction USLast checked September 6, 2026Updates: Amended only by legislation.ID usc-26-4980h-applicable-large-employer
What this source supports (3)
Section 4980H(c)(2) defines applicable large employer as, with respect to a calendar year, an employer who employed an average of at least 50 full-time employees on business days during the preceding calendar year.
Section 4980H(c)(2) provides that in counting, an employer shall, in addition to the number of full-time employees for any month otherwise determined, include for that month a number of full-time employees determined by dividing the aggregate number of hours of service of employees who are not full-time employees for the month by 120.
Section 4980H(c)(4) defines full-time employee as, with respect to any month, an employee who is employed on average at least 30 hours of service per week.
Two thresholds are commonly conflated. Full-time means 30 hours of service per week on average, which is lower than most employers assume, and the 50 employee test is an average over the preceding calendar year that counts part-time hours through the divide-by-120 rule. An employer can therefore become an applicable large employer without ever having 50 people on the payroll at once.

What this source supports (6)
The section is headed Assessable payments under section 4980H(b).
Paragraph (e)(2) provides three affordability safe harbors: the Form W-2 safe harbor, the rate of pay safe harbor, and the federal poverty line safe harbor.
The Form W-2 safe harbor measures the employee contribution against 9.5 percent of that employee's Form W-2 wages from the employer for the calendar year.
The rate of pay safe harbor, for an hourly employee, measures the contribution against 9.5 percent of an amount equal to 130 hours multiplied by the employee's hourly rate of pay.
The federal poverty line safe harbor measures the contribution against 9.5 percent of a monthly amount determined as the federal poverty line for a single individual for the applicable calendar year, divided by 12.
All three safe harbors in this section are expressed against the same 9.5 percent threshold.
