The letter from Anthem landed on Bernadette Cattaneo’s desk on a sunny day in June 2023

Beginning later that summer, it said, the addiction treatment facility she ran in the rural Sierra foothills would no longer be included in several of the insurance company’s networks. 

Confused, she read it again. 

The move could bankrupt The Lakes, one of few facilities of its kind serving a region struggling under a national addiction epidemic.

Anthem didn’t provide much explanation in its initial letter, simply calling the decision “necessary to sustain Anthem’s ability to offer these network products.” 

But Cattaneo had her own hypothesis.  

Over the previous year, she’d engaged in a relentless quest to get Anthem to pay for care she deemed medically necessary for her clients. 

She repeatedly helped her clients appeal to California regulators after the company rejected their claims. 

The Lakes’ clients won 49 of their 54 appeals that year, according to court records, compelling Anthem to pay hundreds of thousands of dollars for alcohol and drug treatment. 

Cattaneo emailed state regulators, saying it didn’t seem coincidental that The Lakes was removed from Anthem’s network after so many successful appeals. 

“The Lakes works tirelessly to provide stellar treatment and this was literally a slap in the face,” she said. 

The conflict between one of the state’s biggest health insurers and The Lakes, tucked away in the tiny town of Copperopolis in Calaveras County, reflects a struggle quietly playing out around California with potentially significant consequences for substance use treatment.

Treatment centers say Anthem — and other major health insurers — employ a variety of tactics that threaten their ability to stay in business, even as California faces a shortage of providers. More than a dozen facility leaders, in lawsuits, state regulatory filings and interviews say insurers are denying their patients’ claims for medically necessary coverage and using punitive measures that prevent treatment centers from getting paid in full. 

As a result, facilities say they get strong-armed into accepting lower reimbursements, go long stretches without receiving payment, or end up not being repaid at all. 

Patients attempting to recover from serious addiction often struggle to find providers who accept their insurance. In some cases, they can face the prospect of having treatment yanked away, or wind up saddled with medical bills their insurance companies won’t fully cover.

Public records obtained by CalMatters show the CEO of one LA County-based treatment center sent letters to state regulators in 2022 imploring them to investigate Anthem for not paying claims promptly, saying his center had been “financially devastated.” Another organization with locations around the state sent a letter to regulators in 2024 complaining that Anthem owed them $1.7 million. 

In September 2023, Cattaneo sued Anthem, alleging the health insurer was punishing The Lakes because of how often staff there appealed coverage denials on behalf of patients. 

Cattaneo believes facilities like hers — family-owned, with no backing from big companies — are “very much taken advantage of.”

“What we’re hoping is that our fight becomes a fight for the whole industry,” she said.

CalMatters made more than half a dozen requests for interviews or comments from Anthem leaders, but company spokesperson Michael Bowman declined, instead sending an emailed statement.

“Anthem is committed to ensuring our provider partners and those delivering care to our members are reimbursed properly and in a timely manner,” he wrote.

In a 2024 letter obtained by CalMatters through the Public Records Act, Anthem’s attorney, Kenneth Smersfelt, wrote to one of Cattaneo’s attorneys that the insurer “remains concerned about The Lakes’ continued failure to comply with the policies and procedures set forth in the Facility Manual.”

He also said the treatment center was taking “an adversarial approach to its relationship with Anthem” that was “inconsistent with a productive and efficient contract relationship.”

Mary Ellen Grant, spokesperson for the California Association of Health Plans, an insurance industry association, told CalMatters that the measures health insurers take are necessary to prevent fraud, a longstanding problem that is “putting patients at risk and driving up the cost of care.” Taking a second look at a requested authorization, she said, ensures services are “safe and appropriate for the patient.”  

Facilities say their payment challenges aren’t limited to Anthem. But as the state’s second biggest health plan, with almost 6 million enrollees, it stands out. 

Among California’s largest health insurers, Anthem’s denials for all forms of health care were most likely to be overturned, according to a CalMatters analysis of data from the Department of Managed Health Care.

When patients appealed to the department, state regulators reversed Anthem’s denials about two-thirds of the time, compared to reversing about half of all insurers’ denials overall.
