California's Legislative Audit Committee has unanimously approved an audit of the state's dental benefits procurement process. This audit puts Delta Dental of California, the state's dominant dental insurer, squarely in the crosshairs of the state’s oversight for the first time in decades.
The audit, supported by the California Dental Association, will examine how the California Department of Human Resources (CalHR) has managed dental coverage for approximately 600,000 state employees, retirees, and their dependents — a population that has been covered exclusively through Delta Dental of California since 1984.
A 40-Year Relationship Under Scrutiny
CalHR's exclusive arrangement with Delta Dental has spanned four decades, but the complaints from state workers and retirees have grown louder. State Sen. Dave Cortese (D-San Jose), who proposed the audit at the committee's June 1 hearing, highlighted a troubling data point: despite four decades of inflation and healthcare cost increases, annual benefit maximums on certain Delta Dental plans have remained stuck at $2,000 for over 40 years.
The situation is compounded by a growing access problem. More state employees report that their dentist is no longer in network with Delta Dental — a trend CDA says confirms that an increasing number of dentists are finding their contracts with the insurer financially unsustainable.
What the Audit Will Examine
The California State Auditor's review is broad in scope. Key objectives include:
Procurement practices — Whether CalHR has followed fair and competitive processes in soliciting bids from dental insurance providers, and what criteria vendors must meet to compete for the contract.
Benefit adequacy — How CalHR determines whether annual maximums and coverage options align with current industry standards.
Utilization and cost data — A review of the past five years of data on plan usage, average out-of-pocket costs for enrollees, and why dentists are leaving the Delta Dental network.
Contract oversight — How CalHR monitors Delta Dental's performance, handles beneficiary complaints, and ensures corrective action when contractual obligations go unmet.
Cost justification — Whether maintaining a sole insurer for over 40 years has been financially justified, and what the contract has actually cost the state over that period.
The audit will also assess whether CalHR has considered expanding plan options — including prepaid plans for out-of-state beneficiaries — and whether it has received competitive bids offering higher annual maximums or more flexible coverage tiers.
CDA Among Supporters
The California Dental Association, which represents more than 27,000 dentists statewide, voiced strong support for the audit alongside the California State Retirees organization. Several legislators from both parties backed the effort, including Sen. Christopher Cabaldon (D-Yolo), Sen. Brian Jones (R-San Diego), and Assemblymember Rhodesia Ransom (D-Stockton).
For CDA, the audit is part of a broader, ongoing campaign to reform what the organization has called a "broken" dental plan system. The association has clashed with Delta Dental repeatedly in recent years — most notably through litigation over a series of contract changes in 2022 and 2023 that CDA alleged included rate reductions of 20 to 40 percent for certain procedures. While a 2025 Court of Appeal ruling closed that particular legal door, CDA has pledged to pursue dental plan reform through legislative and regulatory channels.
A separate class-action lawsuit filed in Los Angeles County Superior Court in April of this year — not led by CDA but watched closely by the association — alleges that Delta Dental of California violated state antitrust laws and the Unfair Business Practices Act through territorial market restrictions that limit competition and suppress provider reimbursement rates.
What's at Stake
The audit represents a significant shift in how California's government views its relationship with the state's largest dental insurer. Until now, the contract has largely operated without independent review. If the audit surfaces evidence of inadequate oversight, suppressed competition, or a procurement process that has failed enrollees, the findings could trigger major changes — including the end of Delta Dental's exclusive hold on California state employee dental benefits.
For the dental profession, the outcome matters beyond state employees. A state auditor's findings carry weight that lawsuits and association advocacy alone do not. An independent determination that Delta Dental's rates are unsustainable for providers — and its benefits inadequate for patients would add a powerful new voice to reform efforts that have been building for years in California.
The audit's results are expected to inform future legislative action and, potentially, a new competitive bidding process when the state's current contract comes up for renewal.
