State high-risk pools were insurance programs created to cover people denied coverage by private insurers because of pre-existing conditions. The first pools launched in Minnesota and Connecticut in 1976, and eventually 35 states operated their own versions, funded by state revenues, enrollee premiums, and fees charged to private insurers.
Before the Affordable Care Act banned pre-existing condition exclusions, these pools were often the only option for seriously ill or injured people unable to get private coverage. Today, most state pools are closed or shrinking, replaced by the ACA marketplace and Medicaid expansions. Only a handful still accept new members, and they serve a much smaller population.

How State High-Risk Pools Were Built
Before the ACA took effect in 2014, 35 states operated high-risk pools to serve two overlapping groups: people denied coverage entirely due to medical history, and HIPAA-eligible individuals (those leaving group employer coverage). States structured funding differently—some drew primarily on state tax dollars, others on premiums from enrolled members, and most on fees or surcharges placed on the private insurance industry to pay for uninsurable populations they refused to cover.
These programs were never designed to be widely accessible. Rather, they functioned as a safety valve for the handful of cases private insurers rejected outright, keeping states compliant with federal law while insurers retained control of most of the market.
The Real Cost of High-Risk Pool Coverage
State high-risk pools were expensive and restrictive for members. Premiums ran 125% to 200% of standard market rates, with high cost-sharing and deductibles, and 33 of 35 pools imposed annual or lifetime benefit caps. Nearly all imposed waiting periods—typically 6 to 12 months—before covering pre-existing conditions, which meant a member could pay premiums for a year before the program paid for the condition that made them uninsurable in the first place.
Despite these barriers, enrollment remained tiny. Fewer than 5% of people who likely qualified for these pools actually enrolled, meaning hundreds of thousands of people with serious medical histories simply remained uninsured. The combination of high cost, long waits, and coverage gaps meant these programs never fully closed the gap they were designed to address.
The Federal Temporary Pool and the ACA Transition
When the Affordable Care Act was being implemented, Congress recognized that the 2010 effective date left a gap: people with pre-existing conditions couldn't yet buy coverage on the new ACA marketplaces, but state pools were too expensive and restrictive to absorb them quickly. Congress funded a $5 billion federal Pre-Existing Condition Insurance Program to provide coverage between 2010 and 2014; new enrollment closed in early 2013, and all coverage ended April 30, 2014, when the ACA's pre-existing condition protections took effect.
This temporary federal program covered roughly 115,000 people—a small number compared to the millions in state pools, but enough to bridge the gap for the sickest, most urgently uninsured members. Once the ACA fully prohibited pre-existing condition exclusions on April 30, 2014, the rationale for high-risk pools effectively vanished.
Which State Pools Still Operate
As of 2023, only five states maintained active high-risk pools: Alaska, California, Idaho, Nebraska, and New Mexico. Alaska and California still accept new members meeting state eligibility criteria. Nebraska's pool exists but serves only Medicare beneficiaries under 65. Idaho and New Mexico are in transition. New Mexico's enrollment fell from over 10,000 members to under 3,000 by 2020, and the state is actively working to close it, encouraging remaining members to switch to ACA marketplace plans or Medicaid. Illinois, which operated a high-risk pool for decades, dissolved its program at the end of 2021 as enrollment dwindled and marketplace alternatives expanded.
Getting Coverage if You Have a Pre-Existing Condition Now
If you have a pre-existing condition and need health coverage today, state high-risk pools are no longer the primary option—and in most states, they're not an option at all. The ACA marketplace (Healthcare.gov or your state's exchange) is open to anyone regardless of medical history, and cannot charge more based on pre-existing conditions. You can enroll during the annual open enrollment period (typically November–January) or if you've had a qualifying life event like job loss or a move.
If your income is low, Medicaid expansion in your state may provide coverage at no or low cost. Some people who can't afford marketplace premiums even with subsidies qualify for fee-for-service assistance programs, state charity care, or hospital financial assistance programs. Checking your state's specific marketplace and Medicaid rules is the fastest way to find what's available to you.
Frequently Asked Questions
Will a high-risk pool coverage deny or exclude me for a pre-existing condition?
Not if you enroll today. The ACA marketplace and Medicaid both cover pre-existing conditions without exclusion periods. Older state pools (before 2014) used 6- to 12-month waiting periods—but those programs are mostly closed. If you live in Alaska or California, which still accept members, check the pool's specific terms.
Are state high-risk pools cheaper than marketplace plans?
No. Pre-ACA state pools charged premiums 125–200% higher than standard market rates. The handful still operating today should be compared directly against ACA marketplace plans in your state, which include subsidies for lower-income enrollees and standardized benefits.
What if I can't afford an ACA marketplace plan?
Apply for Medicaid in your state (eligibility varies), or ask your marketplace for advance premium tax credits that lower your monthly cost. Many hospitals and states also operate charity care and financial assistance programs for uninsured or underinsured people with serious conditions.
