California Regulators Increase Scrutiny of Health Plan Compliance

The California Department of Managed Health Care (DMHC) recently announced two major enforcement actions against Health Net of California, Inc. and Anthem Blue Cross. Although the penalties were issued against insurers, the findings have important implications for healthcare providers navigating payment disputes, reimbursement delays, and patient grievance processes.

Together, the actions demonstrate the DMHC’s continued focus on enforcing statutory timelines and ensuring that health plans properly handle both provider disputes and patient complaints. The cases also reflect growing regulatory pressure on insurers to maintain transparent and compliant systems for resolving claims and grievances.

For providers, these developments reinforce the importance of tracking how payors respond to disputes and whether those responses comply with applicable regulatory requirements.

Health Net Cited for Delayed Provider Dispute Responses

On February 4, 2026, the DMHC issued a $450,000 administrative penalty against Health Net for failing to comply with California’s provider dispute resolution timelines under the Knox-Keene Health Care Service Plan Act.

State regulations require health plans to acknowledge provider disputes within 15 working days and resolve them within 45 working days. These requirements are designed to ensure that providers receive timely responses when contesting denied or underpaid claims.

Following an investigation covering January 2017 through December 2022, regulators found widespread failures by Health Net to meet these deadlines. During certain periods, the insurer failed to comply with required timeframes at least 95 percent of the time. In total, the DMHC documented more than 15,000 late dispute resolutions and over 19,000 late acknowledgments out of approximately 544,000 disputes submitted by providers.

The Department described these delays as a demonstrable and unjust payment pattern under California regulations. Importantly, regulators emphasized that operational challenges such as staffing shortages do not excuse noncompliance with statutory dispute resolution requirements.

Anthem Blue Cross Faces $15 Million Enforcement Action

Just days before the Health Net penalty was announced, the DMHC imposed a far larger enforcement action against Anthem Blue Cross. On January 30, 2026, regulators issued a $15 million penalty tied to longstanding deficiencies in the insurer’s grievance handling system.

According to the Department, Anthem repeatedly failed to properly identify expressions of dissatisfaction by patients as formal grievances. In many cases, the plan also failed to acknowledge or resolve grievances within required timeframes and did not include licensed professionals in quality assurance activities reviewing complaints. Regulators determined that these issues persisted for more than a decade despite previous penalties, corrective action plans, and regulatory oversight. The grievances involved serious matters including delays in care, claim denials, and balance billing disputes.

As part of the resolution, Anthem agreed to a multi-year corrective action plan that will extend through at least 2029. Compliance with the plan will be monitored by an independent third-party auditor who will report directly to the DMHC.

What This Means for Healthcare Providers

These enforcement actions suggest that regulators are paying closer attention to systemic failures in how health plans process disputes and grievances. Providers should view these cases as a reminder that delayed responses, misclassified disputes, and unresolved payment issues may represent broader compliance failures rather than isolated claim problems.

Healthcare organizations can take several proactive steps to protect their interests. Practices should document when insurers fail to acknowledge disputes within 15 working days or resolve them within 45 working days. Retaining written correspondence and claim documentation can help demonstrate patterns of noncompliance.

Providers should also clearly designate submissions as formal provider disputes and follow up when plans attempt to classify them as simple inquiries. When repeated delays or misclassification occurs across multiple claims, escalation through internal payer channels or regulatory complaints may be appropriate.

As regulatory oversight continues to increase, providers who actively monitor dispute timelines and enforce their contractual rights will be better positioned to secure fair and timely reimbursement.
