For Companies

“What distinguishes Knox Ricksen from most other firms is that we actually try complex fraud cases. A lot of firms talk a good game, but the reality is they have limited trial experience. Believe me, at trial, experience matters."
- Tom Fraysse

About Knox Ricksen LLP

The value of experience. That’s what smart clients seek out in a law firm–and nowhere is the value of “we’ve seen this before” more useful than in rooting out and rectifying fraudulent and nefarious activities.

Knox Ricksen LLP is a civil litigation and trial firm dedicated to doing just that–fighting the fraud that cost clients dearly–in terms of financial and human resources, as well as trust and reputational damage. Obtaining winning results is our goal, and our experienced team is focused on prosecuting and litigating complex insurance fraud cases, based on one or more forms of fraud perpetrated against our clients, including healthcare insurers, self-insured groups, and casualty and workers’ compensation insurance carriers.

Drawing on nearly 50 years of dedicated practice, we deliver exceptional results using advanced data analytics and in-depth investigation techniques. From state qui tam actions to RICO suits to healthcare provider lien consolidations, our team expertly guides clients through the court process based on our extensive trial and litigation record–highlighted by significant jury verdicts and hundreds of trials.

We use our experience, expertise, creativity, and perseverance to secure substantial results for clients, including numerous multi-million-dollar judgments and settlements.

Why We Do It

We believe fighting fraud is about more than securing substantial financial settlements—it’s about stopping malicious entities from harming vulnerable populations. In our experience, we have found that insurance fraud is ubiquitous, regardless of locale. It’s everywhere.

The California Insurance Frauds Prevention Act, also known as Insurance Code Section 1871.7, is our weapon of choice. This statute allows insurers to recover ill-gotten funds, as well as facilitating orders that protect against future actions by those submitting false, fraudulent, or capped claims. In most of our work, aggressive and creative use of a full complement of investigative and legal tools–including this statute–is what makes the difference for our clients–both in recouping losses and deterring future malfeasance.

The federal Racketeer Influenced and Corrupt Organizations Act (RICO), when appropriate, is also employed to fight health care and insurance fraud. Insurers often assert civil claims under RICO against fraudsters, and it is no surprise why—the statute provides that successful claimants are entitled to recover treble damages and costs of suit, including attorney’s fees. RICO is thus a powerful tool in our anti-fraud arsenal.

We are passionate about fighting fraud. Beyond successfully prosecuting hundreds of fraud actions, we are long-time leaders in the anti-fraud community. We fully understand the nuances of the law and how to guide these matters to a successful resolution.

What We Do

Knox Ricksen LLP fights for companies and entities that are victims of unfair and fraudulent practices, including:

Healthcare Fraud

We help stop deceptive diversion of healthcare dollars through aggressive and effective healthcare fraud litigation. These cases encompass a range of fraudulent activities including payment of illegal kickbacks, billing fraud, clinical fraud, ownership, operation and control of sham medical corporations and clinics, and other disreputable activities that take a toll on insurers and their insureds and contribute to ever-climbing rates disconnected from quality care.

Our team comprehensively handles large-scale healthcare fraud litigation. We represent casualty, workers’ compensation, and health insurance carriers in complex matters involving sophisticated and organized healthcare fraud.

SIU Consulting

Fraud can undermine and threaten the future of an organization and destroy its profitability, reputation, credibility, and integrity. As a result, many organizations create an internal special investigation unit to identify and investigate suspect activities.

Armed with more nearly 50 years of experience in healthcare fraud and qui tam litigation, Knox Ricksen LLP helps companies identify and quantify fraud risk. Our special investigation unit consultation services incorporate an examination of all aspects of external and internal fraud potential within an organization. We also handle anti-fraud plans, claim file reviews, contract special investigations unit services, fraud audits, fraud awareness training, and regulatory compliance.

Whether through monetary recovery, injunctive relief designed to stop unfair and fraudulent business practices, or implementation of policies and procedures designed to detect and discourage fraud, the team at Knox Ricksen LLP gets results.

How We Do It

We do what it takes to obtain the best possible results for our client. We only take cases in which we genuinely believe. Our clients get a team of leaders and fighters who can negotiate through the thicket of laws and regulations of fraudulent activity. We also have extensive court experience and consistently demonstrate our willingness and ability to take a case to trial.

Personal Attention

For clients large and small, we offer the attention of a boutique firm with the vast resources of a national firm. We seamlessly implement the most advanced legal technology available to increase efficiency, reduce costs, and provide superior services and results.

Collaborative Approach

Fighting fraud and exposing injustice is a team effort between Knox Ricksen LLP and our clients. To ensure clear communication and comfortable collaboration, we provide clients, insureds, experts, and other individuals involved in litigation with peace of mind and a clear explanation of their case and billing. Most importantly, we give their disputes, problems or desires the highest degree of skill and attention.
