Medicaid Enrollment Trends 2026: The Post-Unwinding Picture
Medicaid enrollment peaked at 94 million in March 2023 when COVID's continuous enrollment mandate ended. Since then, 20 million people have been removed from the rolls. As of mid-2026, combined Medicaid/CHIP enrollment stands at approximately 74.3 million (67.1M Medicaid + 7.2M CHIP) — and with work requirements taking effect in January 2027 and immigrant eligibility restrictions starting October 2026, the trajectory points further down.
The Full Arc: 2014–2026
Understanding where Medicaid enrollment stands requires understanding how we got here:
ACA Medicaid expansion begins. Enrollment starts climbing as states expand eligibility to adults up to 138% FPL.
First enrollment peak: 75 million. Starts declining as expansion slows.
Pre-pandemic baseline: 71 million enrolled.
COVID hits. Congress passes continuous enrollment provision — states can't disenroll anyone in exchange for enhanced federal funding.
All-time peak: 94 million. Three years of zero disenrollment inflated rolls by 32%.
Unwinding begins. States start redetermining eligibility for everyone on the rolls.
Enrollment drops to 80 million. Most unwinding complete — 25M+ disenrolled.
Current: 74.3 million. Decline resumed after brief stabilization in late 2024.
The Unwinding: What Happened
Between April 2023 and September 2024, states processed redeterminations for nearly their entire Medicaid populations. The results were revealing:
That last number is the most important: 69% of disenrollments were for procedural reasons — people who didn't return paperwork, not people found ineligible. Only 31% were determined actually ineligible after review.
🤔 What This Means
Depending on your perspective, the high procedural disenrollment rate either means (a) the system failed people who were eligible but couldn't navigate bureaucracy, or (b) many of those 25 million people had moved on — gotten jobs with insurance, moved states, or simply didn't need Medicaid anymore but never bothered to tell anyone. The truth is probably both. But the continuous enrollment mandate clearly kept millions on the rolls who didn't belong there.
State-by-State Changes
Enrollment declines from March 2025 to March 2026 varied dramatically by state:
Largest percentage decline nationally
Non-expansion state, aggressive redeterminations
Non-expansion state, high procedural disenrollment
Largest absolute enrollment, moderate decline
Steady decline from post-pandemic highs
Smallest decline nationally
All 50 states and DC saw enrollment declines from March 2025 to March 2026. Adult enrollment increased in only 6 states (IA, MO, NC, OK, SD, WY).
Children: A Different Story
While overall enrollment is falling, the picture for children is more nuanced. Child enrollment in Medicaid/CHIP declined by 445,000 (1%) from February 2020 to March 2026. CHIP enrollment has actually increased in 19 states, partially offsetting Medicaid losses as children moved between programs.
The 7.2 million children enrolled in CHIP represent a population that's largely shielded from work requirements (which apply to adults in the expansion group). But eligibility changes for immigrant families starting October 2026 could affect some children.
What's Coming: The Work Requirements Effect
Current enrollment of 74.3 million is still 4% above pre-pandemic levels (71M in February 2020), even after 20 million disenrollments. The reconciliation law's provisions will push enrollment lower through several mechanisms:
- Work requirements (Jan 2027) — The largest source of projected enrollment decline. CBO estimates millions of expansion adults may lose coverage.
- Immigrant eligibility restrictions (Oct 2026) — Certain immigrant populations lose Medicaid access.
- Six-month redeterminations — States required to verify eligibility twice a year instead of annually, catching changes faster.
- Reduced FMAP rates — Lower federal matching could lead states to restrict optional populations.
Impact on Provider Billing
Enrollment changes directly affect the providers in our database. Fewer enrollees means fewer billable patients, which means:
- Providers with unusually high patient volumes may see natural corrections
- States with aggressive disenrollment (Indiana: -20%) will see the biggest billing shifts
- Managed care plans are already losing members — 60.4 million in managed care by March 2026, down 4.8% year-over-year
- Providers in our watchlist billing at anomalous levels will face even greater scrutiny as legitimate patient pools shrink
Bottom Line
Medicaid enrollment is normalizing after the artificial pandemic-era inflation. The 94 million peak was never sustainable — it was the predictable result of a policy that banned states from removing anyone from the rolls for three years. The correction to 74.3 million is painful for some, but it's a return to verifying that people on a $900+ billion program actually qualify.
With work requirements, immigrant eligibility changes, and six-month redeterminations ahead, enrollment will likely drop further — potentially below the pre-pandemic 71 million baseline. Whether that represents right-sizing or over-correction depends on how well states implement the new rules.
Frequently Asked Questions
How many people are on Medicaid in 2026?
As of March 2026, Medicaid enrollment stands at approximately 74.3 million — down 21% from the pandemic peak of 94 million, following the end of continuous enrollment protections.
What caused the Medicaid enrollment drop?
The post-pandemic 'unwinding' process required states to redetermine eligibility for all enrollees. Roughly 25 million people lost coverage — some because they no longer qualified, others due to paperwork issues.
Will Medicaid enrollment keep declining?
Work requirements affecting 41 states go into effect January 2027 (Nebraska started early in May 2026). Combined with immigrant eligibility changes in October 2026, CMS projects an additional 7-10 million could lose coverage. Total enrollment could drop below the pre-pandemic 71M baseline.
