Workers' comp kickback fraud

What it is

A treating doctor, chiropractor or medical director gets paid, directly or through a disguised consulting or marketing contract, for every injured worker they send to a specific hospital, surgical center, imaging lab or pharmacy. That facility then bills a workers’ compensation insurer, a state fund, a private carrier, or the US Department of Labor’s program for injured federal employees, for the resulting treatment. The underlying workplace injury is usually real. What’s bought and sold is the referral itself: which provider the patient ends up at, how much treatment they get, and sometimes whether they need surgery at all, decisions a kickback is explicitly designed to distort.

How it actually works

1. The referral relationship

   A treating physician, chiropractor or medical director becomes the funnel: whichever surgical center, imaging lab or pharmacy they refer an injured worker to is the one that gets paid by the insurer, and in these cases, the one paying them back for sending the patient.

2. The kickback

   The facility pays the referring provider a flat fee or a share of future billings for every patient who ends up there, sometimes disguised as a consulting or marketing contract rather than a straightforward payment for referrals.

   Where it could have stopped

   Paying or accepting money for a patient referral is illegal under federal and state anti-kickback law on its own, before an insurer is ever billed a single dollar. In the documented cases on this page, prosecutors charged the kickback payments as separate counts from the billing fraud itself.

3. Inflating the price that funds the kickback

   Some operators use a shell company they control to mark up the price of a surgical implant or device before billing the insurer, with the markup itself generating the cash that pays the kickback, exploiting billing rules, like California’s now-repealed spinal implant pass-through law, that let a provider pass the full, unverified device cost on to the insurer.

4. Treatment driven by the kickback, not the injury

   Spinal fusion surgery, MRIs, injections or pain medication get ordered based on what generates a referral fee for the provider who sent the patient there, rather than solely on independent medical judgment about what the injury requires.

5. Billed to the workers’ comp insurer or federal fund

   The facility submits the claim to the state workers’ compensation system, a private carrier, or, for a federal employee’s claim, the US Department of Labor’s Office of Workers’ Compensation Programs, which pays largely on the provider’s own billing without independently verifying medical necessity before the claim is paid.

6. The worker caught in the middle

   The injured employee undergoes the real surgery or treatment, unaware the referral that sent them there was paid for, with no practical way to know whether the volume or type of care they received was set by their injury or by someone else’s cut.

7. Enforcement, built from billing data and bank records

   State insurance fraud units, IRS Criminal Investigation, the FBI, the US Postal Service Office of Inspector General, the Army Criminal Investigation Division and the Department of Labor’s own Inspector General trace the kickback payments through bank records, consulting-contract paperwork and shell company filings, a process that took years to reach a conviction and sentence in each case documented here.

Why it works

Insurers pay first and verify later, if at all. Like most large payers, a workers’ comp insurer or federal benefit fund processes the overwhelming majority of claims on the treating provider’s own paperwork. Independent, pre-payment review of whether a specific referral or procedure was medically necessary is the exception, not the rule, which is the gap every case on this page exploited for years before being caught.

A billing rule can turn a markup into a kickback fund. California’s now-repealed spinal implant pass-through law let a hospital bill the insurer the device’s full, unverified cost. Pacific Hospital of Long Beach used shell companies it controlled to inflate that cost, then used the markup to fund $40 million in kickbacks over 15 years, a mechanism that worked precisely because the insurer had no way to see past the invoice to the real price.

The patient has no visibility into who is paying whom. An injured worker sees a referral from their own doctor as medical advice, not as a business transaction. Nothing on the paperwork a patient receives discloses whether the provider they were sent to pays the referring doctor a fee, which is what let Garry Craighead build a referral network across six Texas cities, and Ronald Grusd’s clinics bill more than $25 million, before either scheme was caught.

A single payer can be billed through dozens of entities at once. Operators in these cases didn’t rely on one clinic; Craighead formed clinics under at least five different names across Texas, and Pacific Hospital’s kickback network eventually implicated more than 20 separate doctors, chiropractors and marketers, spreading the fraud across enough entities that no single relationship looked unusual on its own.

Federal employee claims add a captive population. The Federal Employees’ Compensation Act gives federal workers one government-run benefit program rather than a market of competing insurers, so Craighead built relationships with union leaders inside agencies like the Bureau of Prisons and the US Postal Service to steer a steady, renewable stream of injured-worker referrals toward clinics chosen for the kickback they paid.

Where it comes from

Entirely domestic: this scheme exploits the billing structure of US workers’ compensation systems, state-run funds, private carriers, and the federal government’s own Office of Workers’ Compensation Programs, which does not exist in this form outside the United States.

California produced the two largest documented schemes here, both run through the state’s own workers’ compensation system. Pacific Hospital of Long Beach’s owner, Michael Drobot, built a 15-year, roughly $600 million kickback network paying doctors and chiropractors for spinal surgery referrals, while Beverly Hills radiologist Ronald Grusd’s companies paid kickbacks to clinics across San Diego and Imperial counties for referrals covering imaging, injections and pain medication, part of a wider “Operation Backlash” investigation that has charged nearly 40 individuals and companies since 2015.

Texas produced the documented case against the federal program instead of a state one. Garry Wayne Craighead’s Union Treatment Centers courted patients covered by the Federal Employees’ Compensation Act, federal employees hurt on the job, and referred them to pharmacies, hospitals and surgical clinics chosen for the kickback they paid him, billing the US Department of Labor’s Office of Workers’ Compensation Programs more than $203 million from 2007 through 2014.

The schemes scale differently depending on who is doing the referring. Drobot and Grusd, as the owners of the facilities being billed, paid kickbacks outward to the doctors and chiropractors sending them patients. Craighead, as the referring provider himself, took kickbacks from the pharmacies and clinics he sent federal employees to, the same underlying crime from the opposite side of the referral.

Real cases

Red flags

• A treating doctor, chiropractor or medical director who always refers to the same single facility, especially one far from where the patient lives or works.
• Pressure to agree to spinal surgery, an implant, or a course of injections quickly, without a clear, independent explanation of why less invasive treatment wasn’t tried first.
• A referring provider who is vague or evasive about any financial relationship with the facility, lab or pharmacy they’re sending you to.
• A consulting, marketing or management services contract between a referring provider and a facility that doesn’t describe any real work being performed.
• A union representative, employer liaison, or federal agency contact who steers injured coworkers toward one specific clinic network rather than letting the worker choose their own provider where the law allows it.
• A bill that includes marked-up device, hardware or implant costs you have no way to independently verify.

If it’s happening to you

If you think your own referral was driven by a kickback rather than your care:

1. Ask who is paying your treating doctor, chiropractor or medical director, and whether they have any financial relationship, consulting fee, or marketing arrangement with the facility, lab or pharmacy they referred you to.
2. Keep your own written record of what diagnosis and treatment you were told you needed, and when, so you have something to compare against later if the recommendation changes.
3. Ask your claims adjuster or your union representative, if you have one, whether the provider network you were referred into has been the subject of any fraud investigation.
4. Get a second opinion from a provider with no relationship to the one who referred you, especially before agreeing to surgery.
5. Report suspected workers’ compensation fraud to your state’s Department of Insurance fraud division. For a federal employee’s Federal Employees’ Compensation Act claim specifically, report it to the US Department of Labor Office of Inspector General hotline at 202-693-6999 or oig.dol.gov.

Where the money goes

Entirely domestic, moving from a workers’ compensation insurer or federal benefit fund into the billing facility’s own accounts, then back out again as kickbacks to the people who sent the patients.

The insurer or fund pays the claim, the daily rate, the surgery bill, the implant cost, directly into the billing facility’s bank account on the strength of the provider’s own paperwork, typically the most traceable step in the chain since it comes from a regulated payer with its own records. From there, the facility’s owner or controlling operator pays kickbacks to the referring doctors, chiropractors and marketers who supplied the patients, in the documented cases here running from roughly $10,000 to $15,000 per spinal surgery referred, sometimes funded by first routing the money through a shell company used to inflate a device’s invoiced price. What’s left moves into real estate, forfeited bank accounts, classic cars, and, in Craighead’s case, an airplane, all eventually seized or ordered forfeited once the scheme was prosecuted.

By the numbers
