Wisconsin Health Insurance Marketplace 2026 Guide

The health insurance marketplace Wisconsin residents use operates through HealthCare.gov — the federally facilitated platform — rather than a state-based exchange. For 2026, twelve carriers offer individual and family plans to Wisconsin residents, down from fourteen in 2025 after Chorus Community Health Plans exited entirely and multiple carriers pulled out of specific counties. The weighted average rate increase across the Wisconsin health insurance marketplace reached 22.8 percent for 2026, the largest single-year jump in several years, driven by the expiration of enhanced federal premium tax credits, post-pandemic utilization trends, and cost-sharing reduction funding uncertainty. Wisconsin’s Healthcare Stability Plan reinsurance program — in effect since 2019 — continues to keep underlying premiums lower than they would otherwise be, but the 2026 increase still produced meaningful sticker-shock for enrollees near or above the subsidy threshold. About 270,000 Wisconsin residents enrolled in 2026 marketplace plans. This guide covers every dimension of the Wisconsin health insurance marketplace for 2026: how HealthCare.gov works for Wisconsin residents, which carriers participate and where they withdrew, the unique BadgerCare Plus coverage gap at 100-138 percent of FPL, subsidy eligibility, and step-by-step enrollment guidance.

How the Wisconsin Health Insurance Marketplace Works

The health insurance marketplace Wisconsin uses operates on HealthCare.gov, the federal platform used by 32 states that do not run their own exchanges. Wisconsin residents enroll, compare plans, apply for subsidies, and select coverage entirely through HealthCare.gov — there is no separate Wisconsin portal. The Wisconsin Office of the Commissioner of Insurance approves rate filings; WisCovered.com provides Wisconsin-specific navigation help.

Wisconsin has used the health insurance marketplace Wisconsin residents rely on since the ACA launched in 2014 and has not pursued a transition to a state-based exchange. The practical effect for Wisconsin residents is the same HealthCare.gov account system, subsidy application, and plan comparison interface that residents of Florida, Texas, and Georgia use. Wisconsin-specific resources — rate filings, consumer guides, and navigator contacts — are maintained by the Wisconsin OCI at oci.wi.gov and through the state’s consumer-facing site WisCovered.com.

One distinctive feature of the Wisconsin health insurance marketplace is the Wisconsin Healthcare Stability Plan — a state reinsurance program launched in 2019 under a federal Section 1332 waiver. Wisconsin’s reinsurance program keeps the health insurance marketplace Wisconsin premiums lower by reimbursing carriers for high-cost claims, reducing the amount carriers need to build into premiums to protect against catastrophic-cost members. According to the Wisconsin OCI, the Healthcare Stability Plan has reduced marketplace premiums by an estimated 10 to 20 percent compared to what they would be without the program. Without it, Wisconsin’s 22.8 percent 2026 rate increase would have been steeper still. Wisconsin’s reinsurance waiver is renewed periodically; its continuation in future years is not guaranteed.

2026 Wisconsin Marketplace Carriers: What Changed and Who Exited

The 2026 health insurance marketplace Wisconsin operates lost two carriers entirely and saw major county-level exits from three more. Chorus Community Health Plans (Children’s Wisconsin) exited the marketplace, displacing approximately 11,000 eastern Wisconsin members. Anthem (Compcare) withdrew from 10 counties, Quartz withdrew from approximately 20 counties, and Common Ground Healthcare Cooperative (operated by CareSource) withdrew from 11 counties including Milwaukee, Racine, and Kenosha.

BadgerCare Plus vs the Wisconsin Marketplace: The 100-138% FPL Gap

Adults seeking the health insurance marketplace Wisconsin offers: Wisconsin covers adults under BadgerCare Plus up to 100 percent of the federal poverty level — approximately $15,650 for a single adult in 2026. Adults between 100 and 138 percent of FPL do not qualify for BadgerCare Plus, but qualify for heavily subsidized Wisconsin marketplace plans through HealthCare.gov. At 100 percent of FPL, premium tax credits and cost-sharing reductions typically bring Silver plan net premiums close to zero.

Wisconsin’s 100-138 percent FPL gap in the health insurance marketplace Wisconsin operates is the direct result of the state’s decision not to adopt full ACA Medicaid expansion. In the 40 states that fully expanded Medicaid, adults with income between 100 and 138 percent of FPL would qualify for Medicaid. In Wisconsin, they do not. They must use the HealthCare.gov marketplace, which does offer them substantial premium tax credits and cost-sharing reductions at this income level. A single adult in Madison earning $17,000 (about 108 percent of FPL) would not qualify for BadgerCare Plus but would qualify for a Silver plan with cost-sharing reductions that could bring their net monthly premium to $20 to $40 and their deductible to well under $1,000.

2026 Open Enrollment Dates and Special Enrollment Periods

Open enrollment for 2026 Wisconsin marketplace coverage ran November 1, 2025 through January 15, 2026 — that window is now closed. Open enrollment for 2027 plan coverage runs November 1 through December 15, 2026, under the federal rule shortening the window. Plans selected by December 15 take effect January 1. Outside open enrollment, Wisconsin residents enroll only through a Special Enrollment Period triggered by a qualifying life event.

The 2027 enrollment window (November 1 – December 15, 2026) is shorter than the window Wisconsin residents used for 2026 coverage, which ran through January 15. The Biden administration had extended the window to January 15 starting with the 2022 plan year; the federal rule change for 2027 returns it to December 15. Plans selected between December 16 and January 15 — which took effect February 1 under the extended window — are no longer available under the shortened schedule. Wisconsin residents who want January 1, 2027 effective dates must enroll by December 15, 2026.

Special Enrollment Periods (SEPs) are available year-round for Wisconsin residents who experience a qualifying life event. Common triggers include: loss of other coverage (job loss, COBRA expiration, aging off a parent’s plan at 26, loss of BadgerCare Plus eligibility), household changes (marriage, divorce, birth, adoption, death of a covered member), residence changes (move to a new Wisconsin ZIP code, move to Wisconsin from another state), and income changes that affect subsidy eligibility. SEPs typically run 60 days from the qualifying event date; documentation of the event must be uploaded to HealthCare.gov. Coverage under an SEP enrollment begins the first of the following month. BadgerCare Plus remains open year-round with no open enrollment requirement through ACCESS Wisconsin at access.wisconsin.gov.

Wisconsin Marketplace Subsidies in 2026

Health insurance marketplace Wisconsin subsidy eligibility runs from 100 to 400 percent of the federal poverty level — approximately $15,650 to $62,600 for a single adult in 2026. Advance Premium Tax Credits reduce monthly premiums; cost-sharing reductions on Silver plans reduce deductibles and out-of-pocket maximums for households between 100 and 250 percent of FPL. The 2025 expiration of enhanced premium tax credits returned the 400 percent subsidy cliff for 2026 Wisconsin enrollees.

The Advance Premium Tax Credit through the health insurance marketplace Wisconsin uses is calculated as the difference between the benchmark Silver plan premium in your rating area and a required contribution percentage of your household income — ranging from roughly 2 percent of income at 100 percent of FPL to 9.6 percent of income at 400 percent. Wisconsin’s benchmark Silver premiums vary by region and age: a 40-year-old in Madison has a lower benchmark than a 40-year-old in northern Wisconsin counties served by Security Health Plan or Aspirus. The KFF subsidy calculator provides state-specific estimates by age, income, and ZIP code. Actual subsidy amounts are determined when you file HealthCare.gov application — estimated amounts may differ from the calculator by a few dollars based on the most recent benchmark plan update.

Cost-sharing reductions are only available on Silver plans — they cannot be applied to Bronze, Gold, or Platinum tiers. A Wisconsin household between 100 and 150 percent of FPL on a CSR Silver plan may see deductibles as low as $150 to $300 and out-of-pocket maximums below $1,500, versus the standard Silver deductible of $4,000 to $5,500. For low-income Wisconsin Marketplace enrollees, the Silver plan with CSR is typically the highest-value option even if the net premium is slightly higher than a Bronze plan.

How to Enroll in the Wisconsin Health Insurance Marketplace

Enrolling in health insurance marketplace Wisconsin coverage takes five steps through HealthCare.gov: create or sign in to your account, complete the household and income application, review eligibility for BadgerCare Plus or premium tax credits, compare available plans filtered to your Wisconsin ZIP code with your subsidy applied, and select a plan. A licensed Wisconsin agent completes all five steps with you at no cost.

Step 1: Create or sign in to your HealthCare.gov account. Wisconsin residents who enrolled in 2025 or earlier have existing accounts; returning users can log in directly and begin the renewal or new plan selection. Step 2: Complete the household and income application — household size, tax-filing status, Wisconsin residency, modified adjusted gross income, and immigration status for all household members. HealthCare.gov auto-screens all applicants for BadgerCare Plus eligibility based on income before presenting marketplace plan options. Wisconsin residents below 100 percent of FPL are routed to BadgerCare Plus through the Wisconsin DHHR. Step 3: Review your eligibility determination — the platform calculates your Advance Premium Tax Credit amount and whether any household members qualify for cost-sharing reductions, BadgerCare Plus, or WCHIP separately.

Step 4: Compare available Wisconsin marketplace plans filtered to your ZIP code. This step is where most planning effort should focus: which carriers serve your county, which network covers your providers (verify UW Health, Aurora, Froedtert, Marshfield Clinic, Bellin, ThedaCare, or Aspirus affiliation specifically), and what the post-subsidy premium is for each metal tier. Step 5: Select a plan and confirm enrollment. Pay the first month’s premium to activate coverage — HealthCare.gov enrollment is not complete until the first premium is paid to the carrier. Coverage begins January 1 for open enrollment selections made by December 15, and the first of the following month for SEP enrollments. A licensed Wisconsin insurance agent or WisCovered.com navigator handles steps 1-5 at no charge — carrier compensation pays the broker, not the consumer.
