What is Medicaid and how does it work in Arizona? Here's what to know
Arizona's $21 billion Medicaid program is government health insurance that as of February provided coverage to roughly one in every four state residents or 2 million people.
Known as the Arizona Health Care Cost Containment System or AHCCCS (pronounced "access"), the state's Medicaid program has been around since 1982 and reached a record-high enrollment of 2.5 million Arizonans in early 2023.
AHCCCS primarily provides health coverage to low-income people typically living at about 138% or less of the federal poverty level and to people with disabilities, though financial thresholds for various programs vary. An annual income of $21,597 per year for a single person is 138% of the federal poverty level and for a family of three, it's an annual household income of $36,777.
Here are seven things to know about AHCCCS in Arizona.
Any Arizonan covered by AHCCCS is covered by Medicaid because they are the same. Medicaid is the name of the federal program and each state has its own Medicaid program. Arizona's program is known as AHCCCS. Some other states have their own names for their Medicaid programs. For example, California's program is called Medi-Cal, Colorado's is called Health First Colorado, and in the state of Washington, it's called Apple Health.
Medicare is a government health insurance program primarily for people over the age of 65. Some people are known as "dual eligible," meaning they have both Medicare and Medicaid coverage. In Arizona, there are 250,000 dual-eligible people enrolled in both Medicare and AHCCCS, state data shows.
Obamacare, which is the same thing as Affordable Care Act health insurance, is not Medicaid or Medicare. Rather, it is private health insurance that is available on state and federal marketplaces with federal subsidies available to eligible people to help pay for it.
Medicaid was authorized in 1965 when President Lyndon Johnson signed the Medicare and Medicaid Act, also known as the Social Security Amendments of 1965, into law. Yet Arizona's program didn't start until nearly two decades later in 1982, when it began as a two-year pilot.
AHCCCS became an independent agency in 1985 under Arizona Gov. Bruce Babbitt, when enrollment was less than 200,000, which is less than 10% of what it is today.
Enrollment numbers have grown as the state's population increased, and as new categories of coverage have been added to the program.
Among the new categories is the Arizona Long Term Care System or ALTCS in 1988; KidsCare in 1999; childless adults living at or below the federal poverty level in 2001; Medicaid eligibility expansion in 2013 as allowed by the federal Affordable Care Act; and in 2016, the state health department's division of behavioral health services moved to AHCCCS, putting the agency in charge of the state's system of mental health care, including Arizonans who need behavioral-health services but do not qualify for AHCCCS.
As of January, 1.1 million AHCCCS enrollees were adults between the ages of 18 and 64, which works out to 54% of enrollees.
Children from newborn through 17 make up more than one-third of all enrollees in the program, with 764,878 children in that age group enrolled statewide as of January, agency data says.
AHCCCS records indicate the agency's budget in the 2017 fiscal year was anticipated to be approximately $11.4 billion, nearly half of what it is today.
Agency officials say the increase is due to several factors, including caseload growth, health care cost inflation and expanded eligibility criteria for its KidsCare program.
In the 2025 fiscal year budget, roughly three-quarters of the agency's funding comes from the federal government and $2.7 billion comes from Arizona's state general fund. The remaining sources of revenue for the program are hospital assessments, county funding, tobacco tax and tobacco settlement money, prescription drug rebate funding and other smaller sources.
Enrollment generally has grown, but it did fluctuate significantly during the Great Recession when KidsCare was frozen and childless adults lost eligibility. Both were later restored. KidsCare is Arizona's version of the federal Children's Health Insurance Program, known as CHIP.
When KidsCare was frozen and before childless adults were restored to AHCCCS eligibility, the amount of uncompensated care at Arizona hospitals rose, and between 17% and 20% of state residents were uninsured. The rate of uninsured people in Arizona as of 2024 was 8.7%, the U.S. Census Bureau says.
Hundreds of millions of dollars in Medicaid money was fleeced from Arizona taxpayers as part of a scheme that preyed on Indigenous people, according to a massive multiagency fraud investigation that revealed its findings in May 2023.
In fiscal year 2019, the behavioral health outpatient billing code, which was one of the main codes the alleged perpetrators were using, billed $53 million to AHCCCS, Attorney General Kris Mayes said. In 2020, it went up to $132 million; in 2021, up to $291 million; and in 2022, up to $668 million, which is more than 12 times the 2019 amount.
During a news conference announcing the fraud, Mayes called the loss of money a "stunning failure of government."
"I don't think it is too much to say that this is one of the biggest scandals in the history of the state of Arizona when it comes to our government," she said.

Congress' "doc fix" spurs value-based care concerns
Physicians are divided over how the massive Republican budget bill moving through Congress would insulate doctors from future Medicare cuts without continuing financial incentives to provide better care through alternative payment models. Why it matters: The "doc fix" championed by the American Medical Association, among other groups, would solve a long-standing complaint about the way Medicare pays physicians. But some physician groups worry it would maintain a system long criticized for tying pay to the volume of procedures delivered and the number of patients seen. State of play: Physician practices that agree to be paid based on patient outcomes get bigger payouts in exchange for taking on the extra financial risk are in line, under current law, for a pay boost through a key adjustment called the conversion factor, starting next year. But the version of the GOP budget bill that passed the House of Representatives would instead create a single conversion factor for all physicians that's updated based on Medicare's measure of inflation. That would leave providers in the performance-based payment models getting higher payments than currently prescribed from 2026 through 2028, but lower payments than outlined in current law after that through 2035, according to an analysis from Berkeley Research Group viewed by Axios. Primary care physicians and providers embracing value-based care worry that removing an incentive for participating in the models will set back efforts to move Medicare toward a more holistic payment system that's meant to improve patient care. "Signals matter in health care," said Shawn Martin, CEO of the American Academy of Family Physicians. "I think it's a signal [to physicians] of an entrenchment back in fee-for-service." The American College of Physicians, the trade group for internal medicine doctors, told lawmakers last month that it's concerned the policy as structured will disincentivize doctors' participation in value-based care. "It's being marketed as a long-term fix," said Mara McDermott, CEO of value-based care advocacy group Accountable for Health. "I don't read it that way. I read it as creating a new cliff." Zoom out: Many provider groups are also concerned that the legislation doesn't fix the 2.83% cut to physicians' Medicare payment that took effect in January. The American College of Surgeons in a May statement praised lawmakers for recognizing that Medicare physician payments have to be adjusted for inflation, but that the legislation's provision "is not sufficient to make up for the 2025 cut, and more work is needed." The other side: The AMA wrote to House leadership last month that it "strongly supports" the provision to consolidate into one conversion factor and tie updates to inflation starting in 2026. Reductions made to the conversion factor over the past half-decade to keep the physician fee schedule budget neutral have made private practice financially impossible for many doctors, the AMA said. "It is absolutely vital that this issue be addressed," the letter to House leaders said. The AMA disagrees that the provision would discourage participation in alternative payment models, it told Axios in an email. Although payment updates to alternative payment model physicians starting in 2029 would be lower than current law provides, those doctors will still get positive payment updates overall, it said. Between the lines: The policy would go into effect as the Trump administration seeks to leverage Medicare alternative payment models to drive HHS Secretary Robert F. Kennedy Jr.'s priorities of prevention and personal choice in health care. The Centers for Medicare and Medicaid Services told Axios it does not comment on proposed legislation, but said it's continuing to prioritize policies that encourage providers to join payment models that reward high-value and coordinated care. Reality check: Just about all physicians and physician trade organizations agree that stable Medicare payment updates with some link to inflation is necessary to ensure continuous access for Medicare patients, AAFP's Martin said. It's "extraordinarily healthy" for physician advocacy groups to have different opinions on exactly how to reach that conclusion, he added. The Senate is currently debating what to include in its own version of the reconciliation bill.

Medicaid churn: How working Americans could mistakenly lose coverage under Trump tax bill
Medicaid churn: How working Americans could mistakenly lose coverage under Trump tax bill Show Caption Hide Caption President Trump gives his thoughts on Elon Musk amid clash on bill President Donald Trump responded to Elon Musk's criticism of his "big, beautiful bill" with disappointment as Musk responded on X. A centerpiece of Donald Trump's tax bill would make millions of Medicaid recipients work, volunteer or study to maintain their publicly-financed health insurance. Republicans say the work requirement is vital to protect taxpayers while motivating nondisabled Medicaid recipients to take charge of their physical and fiscal health. Dr. Mehmet Oz challenged this population to "prove that you matter." But health advocacy groups and analysts say most recipients already work in jobs that don't provide affordable health insurance or pay enough for people to afford their own insurance. They say mandating a Medicaid work requirement − combined with more frequent eligibility checks − would create an administrative nightmare that drops coverage for many who qualify for the public health insurance program for low-income and disabled residents. What is Medicaid churn? Medicaid rolls vary from month to month as people lose eligibility due to a new job, a raise or other income source that disqualifies them for coverage. A job loss or change in life circumstances could make someone newly eligible. The constant change of Medicaid rolls is what health policy experts call churn. A person who temporarily loses coverage due to a paperwork issue or mistake then must again sign up. "Churn is what happens when these eligibility systems become difficult to navigate," said Jennifer Tolbert, deputy director of the program on Medicaid and the uninsured for KFF, a health policy nonprofit. The federal government requires state Medicaid programs to check enrollees eligibility once a year. The Trump tax cut legislation would mandate states double eligibility checks to twice a year. And states would have the added duty of verifying a person's employment or exemption status. The legislation, which passed the House and awaits Senate approval, mandates Medicaid recipients who are "able-bodied" adults without children work 80 hours per month or qualify for an exemption such as being a student, caregiver or having a disability. The bill defines able-bodied as people who are not medically certified as physically or unfit for employment. The legislation also would strip coverage from undocumented immigrants who get Medicaid through state-funded programs. Health policy experts say more frequent eligibility checks and red tape will add administrative costs and cut off people who qualify but fall through the cracks due to administrative miscues. "People are going to have to document work status or exemption status multiple times a year, and at each point there's a risk that someone who is eligible could lose coverage," Tolbert said. Thousands lost coverage under Arkansas work requirement During the first Trump administration, the Centers for Medicare & Medicaid Services gave states the option of implementing a work requirement for nondisabled adults on Medicaid. Arkansas' work requirement cut more than 18,000 residents from Medicaid within the first seven months of the program. People were removed often because people were unaware of paperwork requirements to keep their coverage, research shows and analysts said. In April, a study by researchers from the Urban Institute and Loyola University Chicago found the Arkansas uninsured rate jumped 7.4 percentage points among low-income adults age 30 to 49 after the state's work requirement began. The policy's impact on employment among that age group was "negative, small and statistically insignificant," the study said. Arkansas adults who didn't have access to the internet at home were disproportionately harmed by the policy, a sign adults might've had trouble accessing the state's online portal to report work histories or exemptions, the Urban Institute said. If the work requirement for Medicaid recipients is adopted nationwide, health experts say millions of working poor Americans will inevitably lose coverage. The nonpartisan Congressional Budget Office estimated 10.9 million Americans would lose health insurance coverage through 2034 under the legislation. Most would lose coverage due to the Medicaid work requirement and the twice-a-year eligibility checks, but about 3.1 million would become uninsured from tweaks to Affordable Care Act enrollment, according to a KFF analysis. The ranks of the uninsured could grow larger if Congress doesn't extend the COVID-19 pandemic-era tax credits that have made ACA plans more affordable for consumers. If the tax credits expire and Congress passes the current version of the Trump tax bill, as many as 16 million Americans would lose coverage , according to CBO. "Coverage loss from work requirements should actually be very small," said Kathy Hempstead, a senior policy officer at the Robert Wood Johnson Foundation. "But we anticipate it will be very large, because people will not be able to comply with the requirements and will lose their coverage." Dr. Oz: Medicaid spending is 'crippling the system' The Trump administration's top Medicaid official has defended the House legislation as a necessary step to slow spending for the federal health program that covers nearly 80 million low-income and disabled Americans. In a June 4 interview with Fox Business, Dr. Oz challenged Medicaid recipients who would face work requirements should "prove that you matter." Oz, the Trump-appointed administrator of the Centers for Medicare & Medicaid Services, said the work requirement asks "able-bodied individuals who are able to go back to work at least try to get a job or volunteer or take care of a loved one who needs help or go back into school. Do something to show you have agency over your future." In a Fox News interview posted on the social media site X, Oz said Medicaid spending has surged 50% since 2019, a pace that is "crippling the system." However, some Republicans have pushed back on the proposed cuts. In a May opinion piece in the New York Times, Sen. Josh Hawley, R- Missouri, said "slashing health insurance for the working poor" is "morally wrong and politically suicidal." Survey: Americans worried about Medicaid cuts The public is paying attention to the proposed Medicaid cuts. Slightly more than half of adults said they're worried significant cuts in Medicaid spending would negatively affect their family's ability to obtain and afford health care, according to a KFF health tracking poll released June 6. The survey this survey of 2,539 U.S. adults was conducted online and by telephone over three weeks in May. The survey said nearly 6 in 10 adults said the Trump administration's policies would weaken Medicaid, but there is a stark divide based on party affiliation. Nine in 10 Democrats but just 2 in 10 Republicans expect the administration's policies would weaken Medicaid. Republicans also were far more likely than Democrats to say that the Trump's policies would strengthen Medicaid. Still, while the survey suggests people are tracking the news, many likely wouldn't know whether their coverage has changed until they try to get medical care. "People don't often know that they've lost coverage until they try and fill a prescription or see a doctor," Tolbert said.
