If you're one of the roughly 12 million Americans who qualify for both Medicare and Medicaid — what the insurance world calls a 'dual eligible' — the latest national enrollment numbers deserve your full attention. As of April 2026, total Medicaid and CHIP enrollment across the United States stands at 73.9 million people, according to tracking data maintained by KFF using figures reported by the Centers for Medicare & Medicaid Services. That sounds like a large number, and it is. But the more important figure is the direction: enrollment has dropped by 5 million people, or 6%, in just the past 12 months. Every single state has seen a decline. For Medicare beneficiaries who depend on Medicaid to cover costs that Medicare doesn't, this trend is not abstract — it's a direct threat to your monthly budget and your access to care.
To understand why this matters so much for seniors, you need to understand what Medicaid actually does for Medicare beneficiaries. Medicare covers a lot, but it doesn't cover everything. Part B has a standard premium of $185.00 per month in 2025, and there are deductibles, copays, and coinsurance on top of that. For lower-income Medicare beneficiaries, Medicaid steps in through what are called Medicare Savings Programs — MSPs — to pay some or all of those costs. The most generous level, the Qualified Medicare Beneficiary (QMB) program, covers your Part A and Part B premiums, deductibles, and cost-sharing. The Specified Low-Income Medicare Beneficiary (SLMB) program covers just the Part B premium. These programs can save a dual-eligible senior hundreds of dollars every single month. Losing Medicaid eligibility means losing that financial cushion, often with little warning.
The state-by-state variation in enrollment declines is striking and worth examining closely. According to the KFF tracker, Iowa has seen the smallest decrease — less than 1% — while Indiana has seen the largest, at 20%. That means roughly one in five Medicaid enrollees in Indiana lost coverage over the past year. States like Indiana, which expanded Medicaid under the Affordable Care Act and enrolled large numbers of working-age adults, are seeing the steepest drops as eligibility redeterminations continue to work through the system. For Medicare beneficiaries living in states with large declines, the risk of administrative errors — being dropped from Medicaid even when you still qualify — is higher simply because state agencies are processing enormous volumes of paperwork.
Data Snapshot: According to CMS.gov data reported through the Medicaid Performance Indicator Project, as of April 2026 there were 66.7 million people enrolled in Medicaid and 7.1 million enrolled in CHIP nationally. Adult enrollment has decreased in all but five states — Iowa, Missouri, North Carolina, Oklahoma, and South Dakota — while child enrollment in Medicaid/CHIP decreased in every state and the District of Columbia except Hawaii. These figures represent full-benefit enrollees only and do not include individuals receiving limited Medicaid benefits such as family planning services, meaning the total population affected by Medicaid policy changes is actually larger than these numbers suggest.
Looking ahead, the enrollment picture is likely to get more complicated before it gets simpler. The 2025 reconciliation law — passed by Congress and signed into law — includes a significant new requirement: adults in the Medicaid expansion group and in certain Section 1115 waiver programs will be required to meet work and reporting requirements starting in January 2027. This is not a minor administrative tweak. Policy analysts expect these requirements to reduce Medicaid enrollment substantially over the next decade compared to what enrollment would have been under prior law. For Medicare beneficiaries who are in the expansion group — typically adults between 19 and 64 who gained coverage under the ACA — this is a direct concern. If you are approaching 65 and currently on Medicaid expansion, you need to understand how your transition to Medicare will interact with these new rules.
Here's a practical scenario worth walking through. Suppose you're 63, on Medicaid expansion, and you turn 65 in 2027. You'll become eligible for Medicare, which is good news. But the window between when work requirements kick in (January 2027) and when you age into Medicare can create a gap. If you lose Medicaid before your Medicare start date because you couldn't meet or document a work requirement — or because your state's system made an error — you could face a period with no coverage at all. That's a serious risk, and it's one that requires proactive planning, not a wait-and-see approach. Contact your State Health Insurance Assistance Program (SHIP) counselor — free, unbiased help available in every state — to map out your specific timeline.
For those already on Medicare and Medicaid simultaneously, the most important action right now is to verify that your Medicaid status is current and accurate. States are required to send renewal notices before dropping anyone from Medicaid, but those notices go to the address on file — which may be outdated. If you've moved in the past two years, contact your state Medicaid office directly to update your address. Don't assume the system has your current information. If you receive a notice saying your Medicaid is ending, you have the right to appeal, and in most states you can request a hearing that will keep your coverage in place while the appeal is reviewed. Missing that deadline — typically 10 to 90 days depending on the state — means losing that protection.
For Medicare beneficiaries enrolled in Medicare Advantage plans, the Medicaid connection has another layer of complexity. Many Medicare Advantage plans are specifically designed for dual-eligible beneficiaries — these are called Dual Eligible Special Needs Plans, or D-SNPs. In 2025, there were hundreds of D-SNP options available nationally, and these plans often provide benefits that standard Medicare Advantage plans don't, including transportation to medical appointments, meal delivery after a hospital stay, and expanded dental and vision coverage. But D-SNP eligibility requires that you maintain your Medicaid enrollment. If you lose Medicaid — even temporarily, even due to a paperwork error — you may lose your D-SNP eligibility and be disenrolled from your plan. That triggers a Special Enrollment Period, but navigating a mid-year plan change is stressful and can disrupt your care.
If you're currently in a D-SNP and you receive any communication from your state Medicaid agency, treat it as urgent. Don't set it aside. These notices often have short response windows — sometimes as few as 10 days — and missing them can set off a chain of events that affects both your Medicaid and your Medicare Advantage coverage simultaneously. Your Medicare Advantage plan's member services line can often help you understand what's happening and connect you with resources, but the Medicaid renewal process itself must be handled through your state agency.
The CHIP enrollment trend tells a somewhat different story. While Medicaid enrollment for adults has fallen sharply, CHIP enrollment has actually increased in some states since April 2025. CHIP covers children in families that earn too much to qualify for Medicaid but can't afford private insurance, and it operates somewhat separately from the adult Medicaid system. For Medicare beneficiaries who are grandparents raising grandchildren, or who are helping adult children navigate coverage for their kids, this is useful context: CHIP may still be an option even as adult Medicaid enrollment tightens.
One thing that often surprises Medicare beneficiaries is that Medicaid eligibility rules vary significantly by state — not just in terms of income limits, but in terms of how assets are counted, how renewals are processed, and what benefits are included. A Medicare beneficiary in Texas faces very different Medicaid rules than one in New York or California. In states that did not expand Medicaid under the ACA, the income thresholds for adult coverage are often extremely low — sometimes below 50% of the federal poverty level — meaning many low-income seniors don't qualify for full Medicaid benefits at all, only for the Medicare Savings Programs described earlier. Knowing which programs you qualify for in your specific state is essential, and the income and asset limits are updated periodically, so a determination from two years ago may no longer reflect your current eligibility.
If you're unsure whether you qualify for any Medicaid-related assistance, the Medicare Extra Help program — also called the Low-Income Subsidy, or LIS — is a separate federal program worth knowing about. Extra Help assists with Medicare Part D prescription drug costs and has its own income and asset limits. In 2025, individuals with annual income below roughly $22,590 and assets below $17,220 may qualify. Extra Help is administered by the Social Security Administration, not your state Medicaid office, so even if your Medicaid status is uncertain, you may still be able to get help with drug costs through this separate channel. Apply directly at SSA.gov or by calling Social Security at 1-800-772-1213.
The bottom line for Medicare beneficiaries watching these enrollment trends is this: Medicaid is not a passive benefit that takes care of itself. The current environment — with enrollment declining in every state, new work requirements coming in 2027, and state agencies processing millions of redeterminations — means that errors happen and coverage can be lost even when people still qualify. The seniors who keep their coverage are the ones who stay engaged: they respond to renewal notices promptly, they keep their contact information current with their state Medicaid office, and they reach out to free resources like SHIP counselors or their local Area Agency on Aging when something doesn't look right. If you have any reason to believe your Medicaid status may be at risk, don't wait for a problem to arrive in the mail — make the call today.
