Key 2027 ACA (Obamacare) Changes and What Enrollees Need to Know

For 2027, the ACA (Obamacare) is expected to bring several changes alongside rising premiums — to out-of-pocket limits, to subsidies and eligibility, and to how plans are presented. New Jersey enrollees in particular need to pay attention, because a different enrollment period applies here than on the federal Marketplace.

1. The premium outlook

Based on the rates insurers have filed so far, a national median increase of roughly 15% has been proposed for 2027 ACA premiums. This is not a final approved increase, though, and the actual amount will vary by state, by insurer, and by the enrollee’s age and plan.

The main drivers of the increase are rising medical and drug costs, growing use of GLP-1 weight-loss medications, and the expiration of the enhanced ACA premium tax credits (EPTC) at the end of 2025. As subsidies shrink and relatively healthy enrollees drop their coverage, the average medical cost of those remaining in the market rises — which can push premiums up further still.

2. The cap on what you can be asked to pay is going up too

The annual maximum out-of-pocket (OOP Max) for 2027 ACA plans has been set at $12,000 for an individual and $24,000 for a family. That is an increase of about 13.2% over the 2026 figures of $10,600 for an individual and $21,200 for a family.

The OOP Max is the most you will pay in a year — excluding premiums — in deductibles, copays and coinsurance for covered in-network care. So rather than choosing a plan purely because the premium is low, you should always check the maximum you could be on the hook for if you end up using a lot of care.

3. How plans are presented is changing

Starting in 2027, the rule requiring insurers on HealthCare.gov and other federal Marketplaces to offer Standardized Plans is being repealed. The rules that displayed those plans separately and limited the number of non-standardized plans are going away as well.

That does not necessarily mean existing Standardized Plans disappear — insurers can continue to offer them if they choose. What it does mean is that comparing deductibles, copays, coinsurance and OOP Max across plans yourself is likely to matter more than it used to.

Separately, non-network QHPs may be offered on the Marketplace starting in 2028. Because these have no provider network, enrollees will need to look especially carefully at the conditions for using care and at how cost-sharing is structured.

4. Eligibility and income verification are being tightened

For 2027, the Special Enrollment Period (SEP) based on having income at or below 150% of the federal poverty level (FPL) is again eliminated. Income verification using IRS data and immigration status verification are both being strengthened, so if your income or tax records are not sufficient, additional verification steps may be required.

The ACA’s core consumer protections are not going away, however. Denying coverage because of a pre-existing condition remains prohibited, and central protections such as the ACA’s 10 Essential Health Benefits continue to apply.

5. New Jersey enrollees: watch the enrollment dates

On the federal Marketplace at HealthCare.gov, Open Enrollment for 2027 coverage runs from November 1 to December 15, 2026. But New Jersey operates its own Marketplace, Get Covered New Jersey, so New Jersey residents can enroll from November 1, 2026 through January 31, 2027.

So from the second half of 2026, New Jersey enrollees should be checking their current plan’s 2027 premium and coverage — and comparing not just the monthly premium but subsidies, deductible, copays, coinsurance, OOP Max, and the hospital and physician network together.

The bottom line for 2027: don’t look only at “what is the monthly premium.” Choose the plan that fits you and your family best by also considering the worst-case medical costs you could face over a full year.
