Employers can waive health insurance waiting periods, but the decision rarely rests with the employer alone. For a fully insured plan, the insurance carrier has to agree. For any plan, the written plan document has to permit the waiver, and federal nondiscrimination rules limit how selectively it can be offered. Federal law already caps any waiting period at 90 calendar days, so the real question at a new job is whether your employer will shorten that window or eliminate it entirely.
What a Waiver Actually Requires
How easily a waiver happens depends on how the plan is funded. With a self-funded plan, the employer pays claims directly and has more room to change terms. With a fully insured plan, the carrier sets the underwriting terms, and any deviation from the agreed-upon waiting period needs the carrier’s explicit approval. If an employer enrolls someone early without that approval, the carrier can deny claims filed during the unauthorized period.
The usual path: a hiring manager or HR representative contacts the carrier or broker, explains the situation, and asks for an exception. Some carriers have standard waiver forms. Others require a formal plan amendment. A few refuse individual exceptions and will only change the waiting period across the board. The answer often depends on how competitive the employer’s account is and whether the carrier views one early enrollment as meaningful risk.
The plan document itself is the governing contract. If it says the waiting period is 60 days, enrolling someone on day one without amending that document creates a compliance problem. Any waiver needs to be either a documented amendment or an exercise of discretion the plan already grants HR under defined circumstances.
Why Employers Can’t Just Waive It for One Person
Waiving the waiting period for a prized executive while making the warehouse team wait 90 days creates legal exposure, though the specific rules turn on how the plan is funded.
For self-insured plans, Section 105(h) of the Internal Revenue Code prohibits discrimination in favor of highly compensated individuals in either eligibility or benefits.1Office of the Law Revision Counsel. 26 US Code 105 – Amounts Received Under Accident and Health Plans If the plan fails the test, favorable tax treatment of benefits paid to those highly compensated employees disappears. The IRS has looked at arrangements where employers applied different probationary periods to different employee classes and concluded that the probationary period chosen by an employer must apply to all employees of that employer.2Internal Revenue Service. Memorandum – Discriminatory Benefits In plain terms, if leadership gets immediate coverage, everyone should.
For fully insured plans, Section 105(h) does not apply. The ACA included a provision extending similar nondiscrimination rules to insured plans, but the IRS indefinitely postponed enforcement and has never issued final regulations. That doesn’t give employers a free hand. The plan document still governs, ERISA fiduciary standards still apply, and selectively waiving terms for favored employees can invite Department of Labor scrutiny. The cleanest approach is to define consistent categories of employees eligible for a shorter or waived waiting period and put that policy in writing.
Practically, this means your odds of a waiver improve when you fit a category the employer already treats differently, or when the employer is willing to extend the same offer to anyone similarly situated.
How to Ask for a Waiver
If you want the waiting period waived or shortened, raise it before you accept the offer, when you still have leverage. Treat it as part of the compensation conversation, not a favor.
Ask HR or the hiring manager three specific things: whether the plan is self-funded or fully insured, what the written waiting period is, and whether the plan document allows exceptions. If the plan is self-funded, the employer can usually move faster. If it’s fully insured, the employer will need to go back to the carrier, which takes time. Build that timeline into your start date discussion.
If a full waiver isn’t on the table, ask for alternatives: a shorter waiting period, a signing bonus sized to cover COBRA premiums during the gap, or a start date adjusted so your coverage begins sooner. Any agreement should be in writing, ideally in the offer letter, with the coverage effective date spelled out. Verbal promises from a hiring manager won’t bind the carrier or override the plan document.
What You’re Negotiating Against: The 90-Day Cap
No group health plan can impose a waiting period longer than 90 calendar days. The regulation defines a waiting period as the time that must pass before coverage can become effective for someone who is otherwise eligible to enroll.3eCFR. 45 CFR 147.116 – Prohibition on Waiting Periods That Exceed 90 Days The 90-day count includes weekends and holidays. If a plan lets you elect coverage that begins on or before the 91st day, the plan is compliant even if you take a few extra days to submit your enrollment paperwork.
The cap is a ceiling, not a floor. Plenty of employers set 30-day or 60-day waiting periods, and some start coverage on day one. When you see a 90-day wait, the employer has chosen the maximum the law allows, and nothing in federal law prevents them from offering something shorter.
Some employers also add a “bona fide orientation period” before the waiting period starts. During orientation, the employer evaluates fit, completes onboarding, or runs training. Federal rules allow this, but only if the orientation does not exceed one month.4eCFR. 45 CFR 147.116 – Prohibition on Waiting Periods That Exceed 90 Days One month means adding one calendar month to the start date and subtracting one day. Start on May 3, and orientation can run through June 2 at most. Then the 90-day clock begins. Worst case, a new hire can face roughly four months between start date and first day of coverage. Ask during the interview process whether the employer uses an orientation period at all.
If the Waiver Isn’t Granted
If your new employer can’t or won’t waive the waiting period, you have options for bridging the gap.
COBRA from your prior employer. If you had group coverage at your last job, you can elect COBRA continuation coverage for up to 18 months after leaving, or 36 months in some situations like divorce or a dependent aging out. COBRA keeps you on the same plan with the same providers, but you pay the full premium plus a 2% administrative fee. Expensive, but for a 60- or 90-day gap it can be worth it to maintain continuity, especially mid-treatment.5US Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers COBRA election typically must happen within 60 days of losing coverage.
An ACA Marketplace plan. Losing job-based coverage qualifies you for a Special Enrollment Period, giving you 60 days from your coverage loss to pick a plan. Marketplace coverage can be substantially cheaper than COBRA if you qualify for premium tax credits based on your income. Once your employer coverage kicks in, you cancel the marketplace plan.6Healthcare.gov. Special Enrollment Periods for Complex Health Care Issues
Short-term health insurance. These plans offer limited coverage at lower premiums. A 2024 federal rule restricted initial contract terms to three months with a maximum total duration of four months, but federal agencies announced in 2025 that they are reconsidering those limits and will not prioritize enforcement in the meantime. State rules vary widely, with some states imposing their own duration caps or banning short-term plans altogether. These plans do not cover pre-existing conditions and are not minimum essential coverage, so treat them as a last resort.
Whichever bridge you choose, mind the deadlines. Missing the COBRA or Marketplace window can leave you without options until your employer coverage finally starts or the next open enrollment period.
Union and Multiemployer Plans Work Differently
If you’re covered under a multiemployer plan, common in unionized construction and hospitality work, the eligibility structure isn’t calendar-based. These plans often require employees to accumulate a set number of hours across one or more contributing employers before coverage starts. Federal regulations allow cumulative hours-of-service requirements of up to 1,200 hours without treating the condition as a disguised waiting period violation.4eCFR. 45 CFR 147.116 – Prohibition on Waiting Periods That Exceed 90 Days In this setting, the question isn’t really about waiving a waiting period; it’s about logging enough hours to clear the eligibility threshold.
