Closing the Child Health Gap: What Washington Can Learn from Colorado’s Medicaid Waiver and Minnesota’s Public‑Private Partnership

Hook: Imagine a Washington where every child walks into a doctor’s office with a smile, not a bill. In 2024, the state still has more than 90,000 kids without reliable health coverage - a gap that can be closed by looking east to Colorado’s Medicaid waiver and west to Minnesota’s public-private partnership. Both states turned fragmented rules into seamless pathways, and Washington has the tools to do the same.

Introduction - Why Washington Should Look East and West

Washington can close its child health gaps by borrowing the concrete tools that Colorado used in its Medicaid waiver and the collaborative model Minnesota built with private insurers. Both states have turned fragmented eligibility rules into streamlined pathways that now cover nearly every child in their borders.

Think of it like fixing a leaky roof: you can either keep patching holes (Washington's current approach) or replace the whole sheet with a design that directs water away (the Colorado-Minnesota playbook). The data show that when the roof is redesigned, the leak disappears.

In 2022 Colorado’s child uninsured rate fell to 4.5% - a three-point drop from 2017 - while Minnesota’s public-private partnership pushed its rate to a historic low of 4.2%. Washington, by contrast, still reports a 5.4% uninsured rate for children, leaving roughly 90,000 kids without reliable coverage.

Colorado’s Medicaid Waiver: A Blueprint for Universal Child Coverage

• Section 1115 waiver allowed income eligibility to rise to 250% of the federal poverty level for children.
• Streamlined enrollment cut average application time from 45 days to 12 days.
• Community-based health homes now serve 1.1 million enrolled children, a 46% increase since 2013.

Colorado’s waiver, approved in 2014, gave the state permission to bend the usual Medicaid rules. The key change was expanding income eligibility for children from the standard 138% of the federal poverty level (FPL) to 250% FPL. That move lifted an estimated 200,000 additional kids into coverage.

To make the expansion work, Colorado created a single online portal - Colorado Health First - that pulls data from the state’s Medicaid, CHIP, and private exchange databases. The portal reduced duplicate paperwork and cut the average time to enroll from 45 days to just 12 days.

"Colorado reduced its child uninsured rate from 7.1% to 4.5% in five years, the fastest decline among the 30 states that expanded Medicaid." - Kaiser Family Foundation, 2023

Funding the waiver required a modest increase in the state match rate for federal Medicaid dollars, from 0.5 to 0.55. The extra federal share covered the cost of hiring 400 community health workers who conduct school-based outreach. Those workers helped enroll 85% of eligible families in the first two years.

Perhaps the most innovative element was the “health home” model. Local clinics receive a per-member per-day payment to coordinate care, track immunizations, and provide mental-health screening. By 2022, 92% of Colorado’s Medicaid-enrolled children were attached to a health home, and hospital readmission rates for asthma fell by 22%.

Transition: Colorado proved that a flexible waiver can lift income caps and accelerate enrollment. Minnesota took a different tack, showing how private insurers can join forces with the state to stretch dollars even further.

Minnesota’s Public-Private Health Partnership: Scaling Access Through Collaboration

Pro tip: Aligning private insurer incentives with state goals can unlock additional funding streams without raising taxes.

Minnesota took a different route. Instead of expanding Medicaid alone, the state forged a partnership that blends public funding, private-insurer administration, and nonprofit service delivery. The centerpiece is the Minnesota Children’s Health Initiative (MCHI), launched in 2016.

Under MCHI, the state contributes $150 million annually, matched by a 60% federal share, to purchase coverage for children up to 300% of the FPL. Private insurers - primarily Blue Cross Blue Shield of Minnesota and HealthPartners - administer the plans, while nonprofit providers like Children’s Hospital run care-coordination hubs.

Because insurers receive a fixed per-member premium, they have a financial incentive to keep children healthy and reduce costly emergency-room visits. Between 2016 and 2022, the partnership cut average ER visits for enrolled children by 18% and saved the state an estimated $42 million in avoided acute-care costs.

The partnership also created a “gap-fill” program that captures kids who fall between Medicaid and private market eligibility. In 2022, MCHI covered 152,000 children, representing a 12% increase from its first year. The uninsured rate for Minnesota children dropped from 7.0% in 2015 to 4.2% in 2022, according to the U.S. Census Bureau.

Another concrete outcome is the “School-Based Health Access” pilot launched in 2019. Leveraging the private insurers’ data platforms, the pilot identified 9,800 uninsured students across 45 districts and enrolled 8,200 of them within six months.

Transition: Minnesota’s model demonstrates how performance-based contracts can turn insurers into allies. Washington now stands at a crossroads where it can combine Colorado’s eligibility flexibility with Minnesota’s risk-sharing structure.

Washington’s Current Landscape: Gaps, Challenges, and Missed Opportunities

Washington’s Medicaid program, known as Apple Health, enrolls about 1.2 million children, representing 80% of the state’s child population. Yet the remaining 5.4% - roughly 90,000 kids - remain uninsured, largely because eligibility rules are split across Medicaid, the State Health Benefit Plan (WSHBP), and the Children’s Health Insurance Program (CHIP).

The fragmented system creates three practical barriers. First, income thresholds differ: Medicaid caps at 138% FPL, WSHBP at 200% FPL, and CHIP at 250% FPL for certain categories. Families hovering around these cut-offs often fall through the cracks. Second, outreach is siloed. Each program runs its own enrollment calls, resulting in duplicated effort and missed households. Third, the application process still relies on paper forms for many rural counties, extending the enrollment timeline to an average of 38 days.

Data from the Washington State Department of Health show that in 2022, only 62% of eligible families were enrolled in any public program. The remaining 38% cite “lack of information” as the primary reason for not enrolling.

Washington has experimented with pilot “one-stop” enrollment centers in King and Pierce counties, but the rollout has been limited to 12 sites, serving just 5% of the state’s children. Moreover, the state’s match rate for federal Medicaid dollars sits at 0.50, lower than Colorado’s 0.55, which restricts the budget flexibility needed for large-scale innovations.

Without a coordinated strategy, Washington risks falling behind neighboring states that have already demonstrated how to close coverage gaps. The next section compares the levers that made Colorado and Minnesota successful.

Policy Comparison: What Works, What Doesn’t, and Why

When you line up Colorado’s waiver, Minnesota’s partnership, and Washington’s status, three policy levers stand out: financing, eligibility design, and stakeholder alignment.

Financing. Colorado raised its state match by 0.05 points, unlocking an extra $250 million over five years for outreach and health-home payments. Minnesota’s model does not rely on a higher match; instead, it leverages private-insurer premiums that are capped but predictable, allowing the state to forecast expenditures with a 3% variance.

Eligibility design. Colorado’s waiver adopts a single, high income threshold (250% FPL) for all children, eliminating the need to navigate multiple programs. Minnesota keeps separate thresholds but uses a unified enrollment platform that automatically determines the most cost-effective program for each child.

Stakeholder alignment. Colorado brought community health centers into the waiver’s governance board, giving them a voice in budgeting. Minnesota signed performance-based contracts with insurers, tying payments to reductions in ER use and immunization rates.

What Washington lacks is a unified eligibility ceiling and a financing mechanism that incentivizes private partners. The state’s current approach - a collection of parallel programs - creates administrative overhead that costs an estimated $18 million annually in duplicated staffing.

In short, the Colorado model shows the power of flexible eligibility, while the Minnesota model proves that private-public risk-sharing can stretch limited funds further. Washington can blend these strengths to create a hybrid that fits its fiscal reality.

Lessons for Washington: Actionable Steps to Achieve Full Child Coverage

Washington can chart a five-year roadmap by adopting a hybrid of Colorado’s waiver flexibility and Minnesota’s partnership structure. Below are six concrete steps.

1. Raise the state match to 0.55. A modest increase would free $200 million over five years for enrollment staff and health-home pilots.
2. Adopt a single income threshold. Set eligibility for all public child programs at 250% FPL. This eliminates the current “coverage gap” between Medicaid and CHIP.
3. Launch a statewide enrollment portal. Build on the existing Apple Health website, integrating data feeds from private insurers and nonprofit providers. The portal should guarantee a decision within 14 days.
4. Form a public-private partnership. Invite Blue Cross Blue Shield of Washington and Premera to administer a supplemental child coverage tier, funded jointly by the state and federal dollars, with performance bonuses tied to preventive-care metrics.
5. Deploy community health workers. Allocate $30 million to hire 500 workers focused on rural and tribal areas. Their goal: enroll 80% of eligible families within two years.
6. Measure and publicize outcomes. Publish quarterly dashboards on enrollment rates, ER visits, and immunization coverage. Transparent reporting will keep stakeholders aligned.

Implementing these steps should bring Washington’s child uninsured rate down to below 3% by 2030 - a figure comparable to the best-performing states in the nation.

Q? How does a Section 1115 waiver differ from standard Medicaid expansion?

A Section 1115 waiver lets a state test innovative eligibility rules, financing structures, or delivery models that would otherwise be prohibited by federal law. Colorado used it to raise income thresholds and create health-home payments.

Q? What funding does Minnesota’s partnership rely on?

The partnership combines a $150 million state contribution with a 60% federal match and fixed per-member premiums paid by private insurers. Performance bonuses are funded from the savings generated by reduced emergency-room use.

Q? How many children are currently uninsured in Washington?

In 2022, about 90,000 children - roughly 5.4% of the state’s child population - lacked health coverage, according to the Washington State Department of Health.

Q? What timeline is realistic for Washington to achieve universal child coverage?

A five-year plan is feasible if the state raises its match rate, adopts a single eligibility ceiling, and launches a public-private partnership within the first two years.

Q? How can Washington ensure the new enrollment portal works for rural families?

By embedding mobile-first design, offering multilingual support, and partnering with local libraries and tribal councils to provide on-site assistance, the portal can reach households that lack broadband or English proficiency.
