Stark Law and Anti-Kickback for healthcare marketing — the 2026 deep guide
A working reference for founders, general counsel and Compliance Officers who sign off on marketing budgets, referral-programme structures, laboratory-marketing arrangements and treatment-facility marketing contracts. Written against the federal physician self-referral prohibition (Stark Law), the federal Anti-Kickback Statute, and the Eliminating Kickbacks in Recovery Act — the three statutes that decide which marketing structures are safe and which are enforcement risks.
- Stark Law (42 USC 1395nn) is a strict-liability civil statute that prohibits a physician from referring Medicare/Medicaid patients for designated health services to an entity with which the physician has a financial relationship, unless an exception applies. Marketing spend does not create a referral by itself, but marketing dollars that flow value to a referring physician can create a Stark-scrutinised financial relationship.
- The federal Anti-Kickback Statute (AKS, 42 USC 1320a-7b(b)) is an intent-based criminal statute that prohibits knowingly and wilfully offering, paying, soliciting or receiving remuneration to induce or reward federal healthcare programme referrals.
- EKRA (18 USC 220, 2018) applies AKS-style prohibitions to all payors — commercial insurance and cash-pay included — for referrals to recovery homes, clinical treatment facilities and clinical laboratories.
- The high-risk marketing structures are per-lead, per-admitted-patient, percentage-of-collections, and equity-share-for-referrals contracts. Fixed-fee retainers set at commercially reasonable fair-market value are the safer default.
- OIG publishes AKS safe harbours at 42 CFR 1001.952. Meeting a safe harbour is a defence; not meeting one is not automatic liability but does remove the presumption.

“They were able to get all my ideas and work with me over a period of three to four months and create this amazing website. It's super customized, very modern, and it incorporates all the elements that I had wanted — the patient portal, nice pictures, a very interactive website, patient reviews. I would highly recommend their company to anyone who wants to make an excellent website.”
The three statutes at a glance
Three federal statutes together shape which marketing arrangements are safe and which are enforcement risks. They overlap in some fact patterns and diverge in others, and understanding which one applies where is the first move.
| Statute | Type | Scope | Payors |
|---|---|---|---|
| Stark Law (42 USC 1395nn) | Strict-liability civil | Physician self-referral for designated health services | Medicare and Medicaid |
| Federal Anti-Kickback Statute (42 USC 1320a-7b(b)) | Intent-based criminal + civil | Remuneration for referrals | Federal healthcare programmes |
| EKRA (18 USC 220) | Intent-based criminal | Remuneration for referrals to recovery homes, clinical treatment facilities, clinical laboratories | All payors — including commercial and cash-pay |
Stark Law — the physician self-referral prohibition
Stark Law (also known as the physician self-referral law) prohibits a physician from making a referral to an entity for the furnishing of designated health services payable by Medicare or Medicaid if the physician (or an immediate family member) has a financial relationship with the entity, unless a Stark exception applies.
Designated health services (DHS) are enumerated at 42 CFR 411.351 and include clinical laboratory services, physical therapy, occupational therapy, radiology and other imaging, radiation therapy, durable medical equipment, home health services, outpatient prescription drugs, and inpatient and outpatient hospital services. If a marketing arrangement involves referrals for any of these services, Stark analysis is required.
Financial relationship is defined broadly to include ownership, investment interest, or any compensation arrangement. Compensation includes cash payments, in-kind benefits, discounts, and — critically for marketing — subsidised marketing services provided to the physician by the DHS entity.
Why Stark is strict liability
Unlike AKS, Stark does not require intent. A referral that violates Stark is a violation regardless of whether the physician or the entity knew about the financial relationship or intended to route the referral. This is why Stark exceptions matter so much — meeting an exception is the only reliable defence.
Common Stark exceptions used in marketing structures include the in-office ancillary services exception (42 CFR 411.355(b)), the personal services arrangements exception (42 CFR 411.357(d)), the fair-market-value exception (42 CFR 411.357(l)), and the group-practice exception. Each exception has a specific set of elements that must all be met.
Marketing-relevant Stark patterns
- Hospital-employed physician marketing. A hospital that markets a specific employed physician creates value that flows to that physician. Stark analysis focuses on whether the compensation arrangement between hospital and physician sits inside a Stark exception, particularly the employment exception and the fair-market-value exception.
- Co-branded marketing with a referring group. A DHS entity that co-brands marketing with a referring physician practice may be providing a subsidised marketing benefit. This benefit is compensation for Stark purposes and must fit inside an exception.
- Physician-liaison programmes. Structured referring-physician outreach programmes — dinners, education events, gift-giving — must respect the Stark non-monetary compensation limit (adjusted annually) and the medical staff incidental benefits exception.
The Anti-Kickback Statute — the intent-based prohibition
The federal Anti-Kickback Statute prohibits knowingly and wilfully offering, paying, soliciting or receiving any remuneration (in cash or in kind, directly or indirectly, overtly or covertly) in return for referring an individual for the furnishing of any item or service payable by a federal healthcare programme, or in return for purchasing, leasing, ordering or arranging for or recommending purchasing, leasing or ordering any good, facility, service or item payable by a federal healthcare programme.
The intent element — knowingly and wilfully — is what distinguishes AKS from Stark. AKS liability requires proof that the parties knew the arrangement was improper and acted to effectuate it anyway. The 2010 Affordable Care Act clarified that AKS violations do not require specific intent to violate the statute itself; general knowledge that the conduct was wrongful is sufficient.
The "one purpose" rule
Under the "one purpose" rule adopted by every federal circuit that has considered the question, a payment can violate AKS even if only one of its purposes was to induce referrals — even where the arrangement has other legitimate purposes. This is why arrangements with mixed motives can create AKS exposure that clients underestimate. The analysis is not whether the arrangement has a legitimate business purpose; it is whether inducing referrals was any part of the purpose.
Marketing structures under AKS scrutiny
- Per-referral marketing fees. Contracts that pay a marketing vendor per lead delivered, per appointment scheduled, or per patient treated create a direct financial reward for producing referrals.
- Percentage-of-collections marketing. Contracts that pay a vendor a percentage of the revenue generated by patients that the vendor attributes to its marketing effort tie payment directly to the volume and value of federal healthcare programme business.
- Bonus structures tied to conversion. Even fixed-fee retainers can carry AKS risk if they include performance bonuses keyed to admissions, procedures or specific-payor revenue.
- Equity-share arrangements. Marketing vendors that take equity in referring entities, or referring entities that hold equity in marketing vendors, sit inside a Stark and AKS overlap that requires careful safe-harbour or exception analysis.
EKRA — the 2018 all-payor prohibition
EKRA (Eliminating Kickbacks in Recovery Act) was enacted in 2018 as part of the SUPPORT Act. It expands AKS-style prohibitions in three important ways.
- All-payor scope. EKRA applies to referrals paid by any payor, not just federal healthcare programmes. Commercial-insurance patients and cash-pay patients are covered.
- Narrow vertical. EKRA covers referrals to recovery homes, clinical treatment facilities and clinical laboratories. It does not cover the full breadth of healthcare that AKS covers, but where it does apply, it applies to every payment source.
- Narrower safe harbour. EKRA has a narrower safe-harbour framework than AKS. The employment safe harbour, for example, requires that compensation "not be determined by or vary by" the number of individuals referred — a stricter standard than the AKS equivalent.
The practical implication for marketing is that pay-per-admission call-centre contracts and per-lead payment models tied to admitted patients — long defensible in the commercial-only context — are now within EKRA's zone of concern for the covered verticals. DOJ has brought enforcement actions against non-conforming arrangements since the statute took effect.
Where marketing spend actually touches the statutes
Marketing spend by itself is not a Stark, AKS or EKRA problem. Buying Google Ads, hiring an SEO agency, running Meta campaigns and producing YouTube content are ordinary business activities. The statutes activate where the marketing structure introduces one of three fact patterns.
Fact pattern 1 — value flowing to a referring physician
A DHS entity that subsidises the marketing of a referring physician practice — for example, by paying for the practice's Google Ads campaign, by co-branding advertising, or by providing marketing services below fair-market value — is transferring value to the physician. If the physician makes DHS referrals to the entity, Stark applies and the arrangement must fit inside an exception.
Fact pattern 2 — payment structure tied to referral volume
A marketing vendor whose compensation is tied to the volume or value of patients delivered — per lead, per appointment, per admitted patient, percentage-of-collections — is being compensated in a way that AKS treats as remuneration for referrals. The vendor is not a physician, but it is being paid to "arrange for or recommend" the entity's services, which is enough to trigger AKS.
Fact pattern 3 — EKRA vertical with performance-linked pay
In addiction treatment, clinical laboratory and recovery-home marketing, any performance-linked pay to a marketing vendor — regardless of payor mix — is inside EKRA's zone of concern. Fixed-fee retainers are the safer default.
Safe harbours, exceptions and fair-market value
OIG publishes AKS safe harbours at 42 CFR 1001.952 and CMS publishes Stark exceptions at 42 CFR 411.355-357. Meeting a safe harbour or exception is a defence to liability; failing to meet one is not automatic liability but removes the presumption of legality.
Personal services safe harbour (AKS)
The personal services safe harbour at 42 CFR 1001.952(d) covers many marketing-agency contracts if the following elements are all met: a written agreement signed by the parties, the agreement covers all services to be provided over its term, the aggregate services are not more than reasonably necessary, the term is not less than one year, the compensation is set in advance and consistent with fair-market value, the compensation is not determined by the volume or value of referrals, and the services do not involve the promotion of unlawful activity.
Fair-market value in practice
Fair-market value (FMV) is the operational lever most marketing contracts rely on. FMV means the price that an asset would bring in a bona fide bargained transaction between well-informed parties who are not in a position to generate business for each other. Documented FMV for marketing services generally means a third-party benchmark, a published rate card, or a documented cost-plus analysis from the vendor.
The critical FMV discipline for marketing: the price must be justifiable without reference to the referrals the arrangement produces. If a vendor's fee is set to match the value of the leads the vendor brings in, the FMV analysis collapses.
The written-contract discipline
- Every marketing contract signed for at least 12 months.
- All services enumerated; ad-hoc off-contract work paid separately or added by written amendment.
- Fee set in advance and documented against an FMV benchmark.
- No volume-or-value language anywhere in the compensation structure.
- No provisions that require the vendor to induce referrals.
- OIG advisory-opinion review considered for novel structures.
Marketing structures ranked by risk
Low risk · Fixed-fee retainer at documented FMV
Written contract, minimum 12-month term, all services enumerated, fee set in advance against benchmark, no volume/value language. Sits inside AKS personal-services safe harbour when all elements are met.
Low risk · Cost-plus with capped uplift
Documented cost basis plus a fixed percentage margin. Uplift cap prevents effective volume-scaling. Contract discipline as above.
Medium risk · Fixed retainer + activity bonuses
Bonuses keyed to non-referral activity (content pieces published, campaigns launched, technical milestones met) are more defensible than referral-linked bonuses but still require careful drafting.
High risk · Per-lead payment
Compensation directly tied to lead volume. AKS "one purpose" analysis brings this inside the zone of concern. In EKRA verticals, the risk is acute.
High risk · Per-admitted-patient bonus
Direct payment for delivered federal healthcare programme business (AKS) or, in EKRA verticals, for any admitted patient regardless of payor. Common historical pattern; increasingly unsafe.
High risk · Percentage-of-collections marketing
Marketing fee calculated as a percentage of the collections attributed to the marketing effort. Ties payment to revenue and volume. Presumptively problematic without a specific safe-harbour or exception fit.
How Ichelon Consulting US operates a marketing contract in a Stark/AKS environment
Every US healthcare marketing contract we sign has a compliance discipline layered on top of the commercial structure. The written contract runs minimum 12 months, enumerates all services, sets fee in advance against a benchmark, contains no volume-or-value language, and separates ad-hoc work into written amendments. Where a client operates in an EKRA vertical, we do not accept performance-linked pay structures — the fixed-fee retainer is the only structure we offer.
Attorney review of the specific contract is always the client's call; we make the drafting available for that review.
Stark, AKS and EKRA — common questions
Does Stark Law apply to marketing spend?
Stark does not create liability on marketing spend by itself, but marketing dollars that flow value to a referring physician can create a Stark-scrutinised financial relationship that must fit inside an exception.
How is AKS different from Stark?
AKS is an intent-based criminal-plus-civil statute focused on remuneration for federal healthcare programme referrals. Stark is a strict-liability civil statute focused on physician self-referral for designated health services. Both can be triggered by the same arrangement.
What is EKRA?
EKRA (18 USC 220, 2018) applies AKS-style prohibitions to referrals to recovery homes, clinical treatment facilities and clinical laboratories, across all payors — commercial insurance and cash-pay included.
Are per-lead marketing contracts problematic?
Per-lead and per-admitted-patient marketing contracts are inside the zone of concern for both AKS and EKRA when the contracting entity refers patients into covered services. Fixed-fee retainers at documented fair-market value are the safer default. Attorney review of the contract is essential.
Are there OIG safe harbours?
Yes — 42 CFR 1001.952. The personal services and management contracts safe harbour is the one most marketing agreements try to meet. Meeting a safe harbour is a defence to AKS liability if all elements are satisfied.
Is this guide legal advice?
No. This is marketing best practice reviewed against public regulatory materials. Stark, AKS and EKRA carry criminal and civil penalties and their application is fact-specific. Consult a healthcare regulatory attorney before signing any marketing contract with a physician, laboratory, treatment facility or referring entity.
