The Hess Report Details the Latest Changes in the Arizona Medicaid Market

Arizona's Medicaid program has lost 640,162 enrollees since its peak in July 2022. That is 26.4% of the program, gone in four years. 

This analysis of The Hess Report breaks down what the current AHCCCS population data shows for June 2026: where the losses are concentrated, which programs are still growing, and what the demographic shifts signal. The Hess Report is Arizona's only publicly available, on-demand dashboard offering near real time market intelligence and insights. 

The AHCCCS population decreased by 7,459 members from May 1 to June 1, "less than 1%." No major increases. Routine decreases in three categories.

Seven thousand four hundred fifty-nine people lost Medicaid coverage in a single month. Marking the 19th consecutive month of enrollment decline, against a backdrop of 190,315 members lost in the past year and 640,162 lost since the program's July 2022 peak. 

Here is what the June data shows.

What Moved This Month

We identified three categories driving the May-to-June decline:

Prop 204 Restoration (0–100% FPL): −3,669
This is the largest single-month mover. Prop 204 covers adults below the federal poverty line — Arizona's core low-income expansion population. At 352,216 members as of June 1, this program has now shed 51,175 members in twelve months (−12.7%). This month's loss of 3,669 is consistent with the recent monthly run rate and reflects continued eligibility churn at the lowest income tier.

SOBRA Child: −2,952
The largest program in the AHCCCS portfolio by headcount lost another 2,952 children this month, bringing total enrollment to 524,901. SOBRA Child has now lost 54,280 children over the past year — a 9.4% decline. Nearly 3,000 children per month, month after month. To put a finer point on it: these are children in families earning below 133–147% of the federal poverty level, depending on age. A family of four qualifies with income under roughly $3,658–$4,043 per month. These are working families losing coverage for their kids.

Adult Expansion (100%–133% FPL): −595
The expansion population just above the poverty line shed another 595 members, now at 53,556 total. This group has lost 7,762 members year-over-year (−12.7%). They sit at exactly the same 133% FPL income threshold as children ages 6–18 — meaning any eligibility tightening at that line hits both populations simultaneously, which is reflected in the parallel decline rates.

What Did Not Move — And Why That Matters

AHCCCS reported no major increases this month. But two programs posted modest gains worth noting:

ALTCS: +246
Long-term care enrollment ticked up again, now at 75,661 — part of a consistent structural growth trend. ALTCS has grown 3.1% year-over-year and is up 16.9% from its July 2021 baseline of 64,944. This is the one program in the AHCCCS portfolio that demographic reality is driving upward regardless of policy.

QI-1: +279
The Medicare Savings Program for individuals at 120–135% FPL added 279 members, now at 24,414. QI-1 is up 11.3% year-over-year — the fastest-growing program segment. This growth pattern is partly a function of the same aging dynamic driving ALTCS: as the enrolled population skews older, more members transition toward Medicare dual-eligibility tracks.

The Cumulative Picture These Monthly Numbers Are Building

A single month of 7,459 losses reads as a minor administrative fluctuation. Strung together, the monthly losses tell a different story.

Since July 2022 — the program's peak enrollment of 2,421,521 — AHCCCS has lost 640,162 members. That is 26.4% of the program. The pace has not meaningfully slowed. Over the past twelve months, the program has averaged approximately 15,860 members lost per month. June's 7,459 is actually below that average — which means either this month was a relative lull, or the velocity of decline is beginning to moderate. One month is insufficient to call a trend either direction.

The year-over-year total stands at −190,315 members (−9.7%), and every one of Arizona's 15 counties has declined. Maricopa absorbed the largest raw loss (−111,475), but rural counties — Apache, Coconino, Graham, Greenlee, Navajo — are declining at 11–13%, from a smaller base, with far less capacity to absorb uncompensated care.

The Number Behind the Number: Children and the Uninsured Pipeline

The SOBRA Child decline is the figure that deserves the most attention in this report — not because it moved the most this month, but because of what happens downstream.

The data shows KidsCare — Arizona's CHIP program covering children at 133–225% FPL with a monthly premium — grew by 444 members in June, now at 56,439. KidsCare requires Medicaid ineligibility as a condition of enrollment, meaning some children churning out of SOBRA Child are transitioning upward into CHIP. That is the program working as designed.

But the numbers do not reconcile. SOBRA Child lost 54,280 children over the past year. KidsCare grew by only 853 over the same period. The gap — roughly 53,400 children — did not transition to CHIP. They went uninsured or onto a parent's commercial plan. Given the income levels of this population, the latter is unlikely at scale. The more probable reality is that tens of thousands of Arizona children are now uninsured who were not twelve months ago.

That is a preventive care gap that will generate emergency utilization costs downstream.

The Operational Bottom Line

AHCCCS continues to contract and we've yet to see the full impact of HR1, pending work requirements, and re-eligibility determinations every six months. ALTCS continues to hold as Arizona's population ages; while more children are without coverage today. 

Arizona Medicaid has not stabilized. Plan accordingly.
