Anthem Tops the List of DMHC Enforcement Actions. No Other California Health Plan Even Comes Close.

The California Department of Managed Health Care (DMHC) exists to protect consumers by regulating health care service plans and enforcing some of the nation’s strongest health insurance laws. The agency oversees most HMOs and many PPOs in California, as well as the majority of Medi-Cal managed care plans. In total, approximately 236 health plans, medical groups, providers, and other organizations fall under the DMHC’s jurisdiction. One company, however, stands apart from the rest when it comes to regulatory enforcement actions: Anthem Blue Cross of California.

Unlawful actions by health insurers like Anthem cost plan enrollees in many ways, in terms of delayed or denied health care, financial harm, and undue stress at a time when they are already suffering from an underlying medical issue. The attorneys at Gianelli & Morris step in to hold insurers directly accountable to the people they have harmed, especially when their unlawful conduct amounts to insurance bad faith.

What the Numbers Show

A search of the DMHC’s online enforcement database reveals a striking pattern. Since the database began tracking enforcement matters in July 2000, the agency has published more than 5,400 enforcement documents involving regulated entities. Of those, approximately 1,700 involve Anthem Blue Cross—representing more than 30 percent of all enforcement actions in the database.

The numbers become even more remarkable when compared with Anthem’s largest competitors. As of July 2026, Blue Shield of California appears in approximately 671 enforcement documents, Kaiser Permanente in about 556, and Health Net in roughly 336. Combined, those three major health plans still account for fewer enforcement actions than Anthem alone.

While enforcement statistics do not necessarily tell the whole story, they do raise an important question: Why has one of California’s largest health insurers been the subject of so many regulatory actions?

Why These Numbers Matter

Anthem is unquestionably one of California’s largest health insurers. But it is not three times larger than Blue Shield of California or Kaiser Permanente. In fact, Kaiser is easily the most massive healthcare entity in the state by enrollment and revenue, and Blue Shield is a close runner-up in terms of state market share. Anthem’s enrollment actually comes in behind these other insurers. Its disproportionate share of enforcement matters suggests something more than simple size.

Every enforcement action represents a situation in which the DMHC believed further investigation or corrective action was warranted. Some involve isolated administrative errors. Others identify broader operational or compliance failures that affect multiple policyholders. The violations reflected in Anthem’s enforcement history cover a wide range of issues that directly affect patients’ ability to obtain health care, including:

• Wrongful denials of medically necessary treatment
• Delays in approving referrals and authorizations
• Failure to provide timely access to care
• Improper handling of member grievances and appeals
• Deficient denial notices that fail to explain the reasons for coverage decisions
• Provider directory inaccuracies
• Network adequacy issues
• Utilization review and medical necessity violations

Several of these issues have been the subject of recent enforcement actions discussed many times on this blog, illustrating that regulatory scrutiny often extends well beyond a single type of claim.

Behind Every Enforcement Action Is a Patient

It is easy to view enforcement statistics as numbers on a spreadsheet. In reality, each enforcement matter represents people whose health care was affected. One patient may have waited months for cancer treatment because an authorization was delayed. Another may have been forced to postpone spinal surgery while the insurer repeatedly requested additional documentation. Parents may have been left with thousands of dollars in unexpected hospital bills after a health plan improperly denied coverage for a newborn child. Others may have spent months appealing denials for prescription medications, diagnostic testing, or specialized treatment while their medical conditions continued to worsen.

For these patients, the consequences extend far beyond administrative inconvenience. Delayed or denied care can result in deteriorating health, financial hardship, emotional distress, and prolonged uncertainty at a time when families should be focused on treatment and recovery, not fighting with their insurance company.

How DMHC Enforces California Law

The DMHC’s Office of Enforcement investigates alleged violations of California’s Knox-Keene Health Care Service Plan Act and the regulations adopted under it. Most investigations begin after consumers file complaints that could not be resolved through the health plan’s internal grievance process. The agency also initiates investigations based on audits, market conduct examinations, and other regulatory oversight activities.

When the DMHC determines that a health plan has violated the law, it has several enforcement tools available. These include:

• Administrative penalties that may range from thousands to hundreds of thousands of dollars
• Cease-and-desist orders directing the health plan to stop unlawful practices
• Corrective action plans requiring changes to policies and procedures
• Other administrative remedies designed to bring the health plan into compliance

These actions serve an important public purpose by encouraging compliance with California’s consumer protection laws and helping prevent future violations.

What the DMHC Cannot Do

Although the DMHC plays a critical regulatory role, its authority has important limits. Administrative penalties are generally paid to the State of California, not to the policyholders harmed by the insurer’s conduct. An enforcement action may ultimately help persuade a health plan to approve a previously denied treatment or reimburse a medical bill. It may require the insurer to revise its procedures or stop engaging in unlawful practices. What it generally does not do is compensate consumers for the full extent of the harm they have suffered.

For example, an enforcement action does not reimburse a family for months of emotional stress while trying to secure medically necessary treatment for a loved one. It does not compensate a patient whose condition worsened because care was delayed. It does not make up for lost wages, damaged credit, or the financial burden of paying tens of thousands of dollars out of pocket while a coverage dispute remained unresolved. Those injuries are often far more significant than the administrative penalty imposed by the regulator.

An Enforcement Action Is Not the Same as a Lawsuit

Many consumers assume that once the DMHC finds a violation, the matter is over. That is not necessarily the case. The DMHC’s mission is regulatory enforcement. It ensures that health plans comply with California law and may impose administrative consequences when they do not. Civil litigation serves a different purpose. A lawsuit seeks to determine whether the health plan should be held financially responsible for the harm it caused to an individual policyholder.

This distinction is important because DMHC Letters of Agreement typically provide that they are not admissions of liability and generally may not be used as admissions in later civil or criminal proceedings. Nevertheless, the underlying facts surrounding the insurer’s conduct, its claims-handling practices, internal communications, medical records, and other evidence may become highly relevant in a bad faith lawsuit. In other words, a regulatory enforcement action may identify problems, but it does not replace the need to build a civil case based on admissible evidence.

When Regulatory Violations Become Bad Faith

California law requires health insurers to treat their policyholders fairly and in good faith. When a health plan unreasonably delays or denies medically necessary care, fails to properly investigate a claim, ignores its own policy language, or repeatedly violates well-established legal requirements, those actions may expose the insurer to liability beyond the underlying claim itself. In appropriate cases, policyholders may recover compensation for financial losses, emotional distress, and, where the evidence supports it, punitive damages designed to punish particularly egregious misconduct and discourage similar conduct in the future. Unlike regulatory penalties, these damages are intended to compensate the people who were actually harmed.

Holding Health Plans in California Fully Accountable

At Gianelli & Morris, we regularly represent California policyholders whose health plans have wrongfully denied or delayed medically necessary care. While the DMHC performs an essential role in regulating the health insurance industry, regulatory enforcement is only one piece of the accountability process. When an insurer’s conduct has caused significant financial, physical, or emotional harm, an administrative penalty alone is often not enough. Our attorneys investigate the facts behind the denial, analyze the insurer’s claims-handling practices, evaluate whether California law has been violated, and pursue the full measure of damages available under the law.

The DMHC’s enforcement database tells an important story about regulatory oversight in California. But behind every enforcement action is a patient whose health, finances, and peace of mind may have been profoundly affected. When health plans violate California law, consumers deserve more than regulatory fines paid to the state. They deserve accountability that addresses the full extent of the harm they have suffered. That is precisely what Gianelli & Morris works to achieve for policyholders throughout California.
