Anti-Kickback Statute Explained: Rules, Examples, Safe Harbors, & Penalties (2026)

The Anti-Kickback Statute (AKS), codified at 42 U.S.C. § 1320a-7b(b), makes it a federal crime to knowingly and willfully offer, pay, solicit, or receive remuneration to induce or reward referrals, purchases, orders, or recommendations involving items or services payable by Medicare, Medicaid, or other federal healthcare programs. 

Unlike the Stark Law, AKS is not limited to physicians — it reaches anyone on either side of an improper payment. And unlike Stark’s strict-liability framework, AKS requires knowing and willful conduct (though defendants do not need to know the statute exists to violate it). 

In this article, we’ll be discussiing:

• A practical AKS risk-screening checklist
• Verified 2026 criminal and civil penalty maximums
• Why fair market value alone does not protect an arrangement
• How AKS safe harbors work (and what happens when you fall outside one)
• Scenarios spanning labs, pharma, DME, home health, and physician consulting
• Eight recent DOJ enforcement cases with settlement and prison sentence details

Who does the Anti-Kickback Statute apply to?

AKS covers both sides of a transaction. The person offering or paying improper compensation can face liability — and so can the person soliciting or receiving it.

The statute is not limited to physicians. 

It reaches hospitals, laboratories, pharmaceutical manufacturers, DME suppliers, home health agencies, healthcare marketers, telemedicine platforms, patient recruiters, and any individual or entity involved in arrangements where remuneration connects to federal healthcare program business.

Remuneration includes anything of value — cash, gifts, excessive consulting fees, free rent, travel, entertainment, discounted services, or software. 

The form of the payment does not matter. What matters is whether someone offered, paid, solicited, or received it to induce or reward covered business.

The law also applies to patient-facing inducements. Waiving copayments, providing free transportation beyond permitted limits, or subsidizing medication costs through certain channels can all create AKS exposure.

Why does “knowing and willful” matter?

AKS requires prosecutors to prove that the defendant acted knowingly and willfully. But § 1320a-7b(h) clarifies that a defendant does not need to have actual knowledge of the AKS statute itself or specific intent to violate it.

In practice, this means a healthcare company cannot defend itself by claiming ignorance of the law. “We didn’t know there was an anti-kickback law” is not a defense. Prosecutors must still establish the required knowing and willful conduct under the applicable legal standard — but they do not need to prove the defendant read the statute.

One important consequence of the intent requirement is that it separates AKS from Stark. A physician who accidentally refers a patient to an entity with a financial relationship can violate Stark (strict liability). 

AKS violations require deliberate conduct — though intent may be established from the arrangement’s structure and surrounding evidence, not just a signed confession. 

The same transaction may trigger one law, both, or neither, depending on the facts.

15 Anti-Kickback Statute examples in healthcare

Each example below identifies the arrangement, the AKS concern, relevant protections, and what a compliance review would examine. All examples are hypothetical.

Referral payments

The clearest AKS violations involve direct payments for patient referrals. No subtlety, no disguise — just money changing hands in exchange for Medicare business. These arrangements are prosecuted because they are easy to prove and hard to defend.

Example 1: Cash per patient referred

A diagnostic lab pays a physician $50 for every Medicare patient referred for blood work. No contract exists. No documented services justify the payment.

This is the textbook AKS violation — direct per-referral compensation for federally reimbursable services. No safe harbor protects cash-for-referral payments.

Example 2: Lab pays physician “consulting” fees

A toxicology laboratory enters a consulting agreement with a pain management physician. 

The physician provides minimal consulting services but receives $5,000 monthly — while also referring most patients to the lab for urine drug screening.

The DOJ has pursued this pattern repeatedly. 

The June 2026 laboratory settlements — part of an investigation recovering over $61 million since 2019 — alleged that management-company payments were used to disguise referral rewards.

In January 2026, Labtech Diagnostics agreed to plead guilty to five criminal AKS counts. 

The DOJ alleged that the laboratory disguised referral payments as office rent, phlebotomy compensation, and other seemingly legitimate line items. (The creativity these arrangements sometimes display would be impressive if the consequences weren’t federal felonies.)

Example 3: Pharmaceutical speaker programs

A drug manufacturer pays physicians $1,500 per speaking engagement at restaurant dinners to present information about its branded medication. 

Attendees include the speakers’ friends and family members. Presentations repeat identical content.

The January 2025 Pfizer/Biohaven settlement ($59.75 million) alleged that Biohaven’s speaker programs involved repeated presentations with no meaningful educational benefit for certain attendees, including physicians’ spouses, family members, and friends.

The August 2026 Veloxis resolution ($46+ million) included criminal penalties, civil settlements, and an Open Payments reporting penalty. 

Veloxis admitted providing expensive meals, travel, luxury accommodations, and payments framed as consulting fees to increase prescriptions of its kidney transplant drug.

Compensation arrangements

Most AKS cases do not involve cash in envelopes. 

They involve compensation arrangements that look like legitimate business — consulting fees, medical directorships, marketing contracts — until someone examines whether the payments correlate suspiciously well with referral patterns.

Example 4: Excessive medical director payments

A hospital pays a physician $15,000 monthly for medical director duties requiring 5 hours of work per month. 

Assumed comparable market rates for similar physician administrative services fall in the range of 200–350 per hour (rates vary by specialty and geography).

At $3,000 per hour, the compensation exceeds documented market rates by a wide margin. The personal services safe harbor requires, among other conditions, that compensation reflect fair market value. 

But HHS-OIG’s April 2026 FAQ guidance makes clear that paying fair market value alone does not guarantee AKS compliance — the arrangement’s purpose and structure still matter.

Example 5: Commission-based marketing

A home health agency hires an independent contractor marketer and pays $200 per Medicare patient referred. The marketer visits physician offices, collects patient information, and facilitates referrals.

Per-referral compensation to independent contractors creates significant AKS risk. 

The employee safe harbor protects certain bona fide employment arrangements, but independent contractors fall outside its protection and must satisfy the personal services safe harbor instead — which prohibits compensation based on the volume or value of referrals.

Example 6: Below-market office rent

A specialist rents office space from a hospital at $12 per square foot when comparable space leases for 28–35. The specialist refers Medicare patients to the hospital for inpatient procedures.

Below-market rent can function as indirect remuneration. The rental safe harbor requires a written agreement with compensation reflecting fair market value, among other conditions.

Noncash remuneration

Kickbacks do not need to arrive as wire transfers. 

Luxury travel, free equipment, expensive meals, and gift cards all qualify as remuneration under AKS. The law is indifferent to whether the value shows up in a bank account or in a first-class upgrade.

Example 7: Expensive gifts and travel

A medical device company flies a high-volume surgeon to a Caribbean resort for a three-day “educational retreat.” 

The company pays for airfare, luxury accommodations, meals, and entertainment. The surgeon uses the company’s implants for Medicare patients.

The May 2026 Takeda settlement ($13.67 million) involved allegations of improper payments to healthcare professionals to encourage prescriptions of Trintellix.

Example 8: Free diagnostic equipment

A laboratory provides a physician’s office with free centrifuge and specimen processing equipment. The physician refers patients to the laboratory for testing.

Free equipment that benefits the physician’s practice can constitute remuneration when it flows alongside referrals. (Equipment integral to and used exclusively for the outside laboratory’s own work may receive different treatment.) 

The equipment rental safe harbor requires, among other conditions, a written agreement and fair market value compensation.

Example 9: DME referral incentives

A durable medical equipment supplier offers physicians pre-paid gift cards for each Medicare patient referred for CPAP machines or power wheelchairs.

General-purpose prepaid gift cards function as cash equivalents. 

No safe harbor protects per-referral gift card arrangements. (OIG treats certain restricted-purpose cards differently, but pre-paid Visa cards handed out for Medicare referrals? That’s about as defensible as it sounds.)

Patient-facing arrangements

AKS does not only regulate payments between healthcare businesses. 

Financial inducements directed at patients — waived copays, free transportation, subsidized costs — can also create liability when they function as tools for steering federal program beneficiaries to a particular provider.

Example 10: Routine copayment waivers

A medical practice advertises “no copay” for all Medicare patients and routinely waives the 20% coinsurance without checking financial hardship.

Routine waivers of copayments or deductibles can violate AKS because they function as inducements for patients to choose a particular provider. 

OIG has issued fraud alerts addressing this pattern. The beneficiary inducement CMP provisions add separate exposure.

Example 11: Patient transportation beyond permitted limits

A dialysis center provides free limousine transportation to Medicare patients from up to 90 miles away, bypassing closer competitors.

The local transportation safe harbor under 42 CFR § 1001.952(bb) generally uses a 25-mile limit (75 miles for qualifying rural situations), with specific exceptions for certain post-discharge scenarios. 

Luxury limousine service from 90 miles away fails the safe harbor on multiple conditions — distance, vehicle type, and competitive intent.

Organizational arrangements

Some of the highest-dollar AKS exposure comes from organizational structures — joint ventures, management services companies, and benefit manager arrangements — where the line between legitimate business returns and disguised referral compensation depends entirely on how the deal is built.

Example 12: Pharmacy benefit management rebates

A pharmacy benefit manager negotiates manufacturer rebates and retains a portion without adequately disclosing the arrangements or adjusting reimbursements. 

The retained amounts affect Medicare Part D formulary placements.

HHS-OIG has stated directly that amounts retained by a PBM — even if labeled as rebates — are treated as service or administrative fees and do not qualify for protection under the discount safe harbor. 

Depending on the arrangement, other safe harbors (such as personal services or group purchasing) may be relevant if their conditions are met. The separate prescription drug rebate safe harbor amendments from 2020 remain stayed until January 1, 2032.

Example 13: Hospital-physician joint ventures

A hospital and a group of referring surgeons form a joint venture ambulatory surgery center (ASC). Surgeons receive investment distributions and refer their own patients there for procedures.

The ASC investment safe harbor at 42 CFR § 1001.952(r) specifically addresses qualifying physician investors who perform procedures at ASCs. 

Ordinary ownership-based distributions are not automatically improper. 

But distributions that correlate with individual referral volume — rather than reflecting legitimate investment returns — create substantial AKS risk. 

Whether the venture qualifies depends on investor eligibility, return calculations, and referral relationships.

Example 14: Telemedicine referral arrangements

A telemedicine platform pays physicians per patient encounter when the platform connects patients to specific pharmacies or labs. The physicians receive compensation based on downstream referral volume.

OIG has issued special fraud alerts addressing telemedicine arrangements and referral-based compensation.

Example 15: Management services organization distributions

A management services organization distributes profits to physician investors. 

The distributions are structured as “investment returns” but correlate with laboratory referral volume from each physician investor.

The DOJ reported in June 2026 that its MSO-related laboratory investigations have generated over $61 million in civil settlements since 2019 — covering more than 50 physicians.

What are AKS safe harbors and how do they work?

Safe harbors are regulatory provisions under 42 CFR § 1001.952 that protect specific types of arrangements from AKS prosecution — but only when every condition of the applicable safe harbor is met.

Two facts that often get confused in practice:

Meeting a safe harbor protects the arrangement. Failing to meet a safe harbor does not automatically make the arrangement illegal. OIG’s FAQ guidance confirms that arrangements outside a safe harbor require fact-specific analysis, not automatic condemnation.

Also, paying fair market value is relevant to some safe harbor conditions, but FMV alone does not establish AKS compliance. OIG updated this guidance in April 2026.

Safe harbor	Arrangement type	Conditions to verify
Employment	Bona fide employee compensation	Genuine employment, legitimate services
Personal services	Medical directorships, consulting	Written agreement, specified services, FMV compensation, commercially reasonable
Space rental	Office lease between parties	Written agreement, specified premises, FMV rent, commercially reasonable
Equipment rental	Shared diagnostic equipment	Written agreement, specified equipment, FMV rent
Discounts	Purchase discounts, rebates	Proper disclosure, appropriate reimbursement treatment
Group purchasing	GPO arrangements	Written agreement, required disclosures
Investment interests	Certain qualifying investments	Specific investment structure and return conditions
Value-based arrangements	Care coordination programs	Eligible participants, documented activities, risk conditions (varies by category)

The conditions shown above are selected requirements — each safe harbor has additional regulatory conditions not listed here. 

A safe harbor only protects an arrangement when every condition is met. Meeting four out of five is like answering four out of five security questions — you’re still locked out.

What are the actual penalties for AKS violations?

The penalty framework has multiple layers — and several competing sources still cite outdated figures. The numbers below come from the current statute and 2026 penalty adjustments.
