Dr. Monica Soni, the chief medical officer of Covered California, is on a mission to transform California’s healthcare system.
The state of California is currently gripped by a multidimensional crisis that has stretched far beyond hospital walls and into the state’s streets, shelters and jail cells. Encampments and untreated disorders have become visible markers of a healthcare system under strain.
During a recent conversation with HealthStack, Dr. Soni shares that she believes the state’s healthcare infrastructure can no longer operate as a reactive system focused solely on emergency intervention. Instead, in her position at Covered California, the state’s health insurance marketplace that insures nearly 2 million residents, she’s attempting to use the state’s purchasing power to push insurers toward broader accountability.
“Covered California is what’s known as an active purchaser,” Dr. Soni tells HealthStack. “We negotiate with health plans on price, and we hold them accountable for access, quality and equity.”
Under Dr. Soni’s leadership, Covered California has pushed insurers to expand behavioral health access. The marketplace has also reduced disparities in care and invested more in preventive medicine rather than relying on emergency treatment.
Covered California’s People-First Approach to Affordable Care
Dr. Soni operates at the intersection of healthcare, politics and economics, overseeing medical outcomes and policy for the nation’s largest state health insurance marketplace.
While Covered California helps Californians compare plans, enroll in coverage and determine coverage eligibility for the state’s Medicaid program, the actual challenge for Dr. Soni extends beyond that. For the medical professional, the real work is about redefining the role healthcare systems play in people’s lives long before a crisis point.
As chief medical officer, Dr. Soni has focused heavily on Covered California’s Quality Transformation Initiative. The program shifts the financial relationship between the state and insurers from a passive payment model to what she describes as an “active purchaser” approach.
The program ties insurer performance to patient outcomes across key quality benchmarks. Health plans that fail to meet those standards must contribute a portion of their monthly premiums into a statewide fund. Covered California then reinvests those funds into public health programs. These initiatives improve nutrition access, boost childhood vaccination rates, and expand preventive care for children.
“The initiative has been going on for two years, and so far, we’ve seen a vast majority of insurers improve on the quality of care across key benchmarks while raising nearly $20 million this year to invest in those population health measures,” she says of the early results of the initiative.
Dr. Soni’s Comprehensive Approach To Expand Health Beyond The Exam Room
Long before she oversaw health coverage for millions, Dr. Soni described herself as a girl with a heart for service. Volunteering in a Los Angeles emergency room sparked her lasting interest in health care. There, she saw how social determinants of health shaped patient outcomes.
She recalled how language and cultural barriers influenced care in subtle, but powerful ways. It was routine to see patients who did not understand medical instructions hesitate to use interpreter services. Those moments, she said, revealed how social factors shape health outcomes long before a physician enters the room.
This experience contributed to Dr. Soni adopting a holistic approach to care as a board-certified internal medicine physician. This approach developed during her studies at Harvard Medical School while working in a community clinic. The perspective deepened during her primary care residency at UCSF General Hospital, where she learned that integrating equity, access, and cultural context could help lead to more complete and effective care.
“Given my anthropology background, I was drawn to the idea of looking at health more holistically, how environment, politics and every part of our life play a significant role in health outcomes, and how data and research back that up,” she explains.
After clinical practice, Dr. Soni advanced to senior clinical leadership roles at the Martin Luther King Jr. Outpatient Center and Los Angeles County Department of Health Services, the second-largest municipal health system in the United States.
Beyond the clinic, her influence reached the classroom. Holding professorships at UCLA and Charles R. Drew University, she championed medical equity by diversifying residency programs and building robust talent pipelines.
Dr. Soni later transitioned to New Century Health as Associate Chief Medical Officer. There, she bridged the gap between medicine and technology, spearheading clinical informatics and high-impact value-based care strategies.
New Federal Pressure Raise Concerns On Long Term Outcomes
Covered California was built to implement the Affordable Care Act and subsidies at the state level. The platform now operates as California’s health insurance exchange.
The exchange connects individuals and small businesses to coverage and state federal subsidies under the Affordable Care Act framework. Following its launch, California began adding state-funded subsidies to further reduce costs and expand enrollment beyond federal assistance.
This move helped the marketplace grow into one of the largest exchanges in the country. The state further tightened insurer participation rules to stabilize benefits and pricing.
Covered California now serves millions of residents. But its structure depends on both federal premium tax credits and policy decisions. That balance now faces extreme pressure.
Enhanced Affordable Care Act premium tax credits expired in December 2025 after Congress allowed the extension to lapse. The subsidies had capped enrollee contributions and lowered monthly premiums for millions of Americans.
The One Big Beautiful Bill Act introduced new restrictions on eligibility and coverage rules tied to the Affordable Care Act framework.
The Congressional Budget Office projects that the law would strip 1.8 million people of their advance premium tax credits. Most of these individuals would not qualify for alternative subsidized coverage.
But, the administration has defended the changes as necessary for cost control and fraud reduction. Now the insurers reacts to the changes.
CVS Health announced that Aetna would exit portions of the Affordable Care Act marketplace, citing profitability concerns. Other major insurers like UnitedHealthCare are quietly shrinking their footprints.
These changes limit choice. For many, they trigger coverage lapses, mounting medical debt, and a surge in emergency room visits for physicians to manage.
California may have stronger insulation compared to other states due to its scale and supplemental subsidies. But changes to federal subsidy design are expected to affect affordability and enrollment dynamics in the state.
Leaders like Dr. Soni will have to navigate the shift as policy shakes certainty and access to coverage.
