The Anti-Kickback Statute and 1099 Medical Sales Reps: What 2025 Case Law Actually Changed

If you only remember one thing from this article, remember this: 2025 case law introduced nuance, not a compliance shortcut.
I keep seeing teams hear "Sorensen changed everything" and then assume commission-based 1099 structures are now broadly safe. That is not what the law says, and it is not what prudent compliance teams are doing.
I am not your lawyer, and this is not legal advice. This is a practical operating summary that should help your legal team ask the right questions before you deploy contractor sales models.
What the Anti-Kickback Statute Still Says
The Anti-Kickback Statute, 42 U.S.C. § 1320a-7b(b), makes it a criminal offense to knowingly and willfully offer or pay remuneration to induce referrals for items or services reimbursable by federal healthcare programs (42 U.S.C. § 1320a-7b).
The key word is remuneration. That includes commissions, percentage-based compensation, and other value transfers tied to referral generation.
For most contractor-sales conversations, the relevant safe harbor is the personal services and management contracts safe harbor at 42 C.F.R. § 1001.952(d) (42 C.F.R. § 1001.952). Teams usually focus on one element in particular: compensation cannot be determined in a manner that takes into account referral volume or value.
That language still exists. It has not been repealed or softened.
Enforcement Reality Before the 2025 Cases
Before Sorensen and Marchetti, enforcement agencies already had a long record of scrutiny around independent-contractor commission models in healthcare.
The Office of Inspector General has repeatedly flagged percentage-based compensation structures as high-risk in contractor referral contexts, including in OIG Advisory Opinion 06-02 (OIG Advisory Opinions).
Practitioners also continue to cite settlements where compensation design was central to government theories of liability. Two frequently cited examples involved multimillion-dollar outcomes, roughly $5 million and $12.5 million, tied to commission-linked contractor structures in healthcare-adjacent referral models.
The point is not that every commission plan is per se unlawful. The point is that enforcement attention has been real for years, and structure quality has always mattered.
What Sorensen and Marchetti Changed
The 7th Circuit decision in United States v. Sorensen (2025) and the 5th Circuit decision in United States v. Marchetti (2024) shifted emphasis toward fact-specific influence analysis (summary discussion: FDA Law Blog).
In plain language, courts looked harder at whether the compensated person had meaningful influence over referral decisions, not just whether compensation was variable.
That is important. It means some defendants may have stronger factual defenses than older summaries implied.
It does not mean a green light for sloppy commission structures.
What Did Not Change After Sorensen and Marchetti
- AKS statutory text did not change.
- Safe-harbor requirements under 42 C.F.R. § 1001.952(d) did not change.
- OIG concern around referral-linked compensation did not disappear.
- The burden on companies to document structure, scope, and fair-market-value rationale did not decrease.
If anything, the practical burden increased because fact-specific analysis requires better records and tighter operational discipline.
Why Many Compliance Teams Still Prefer Hourly 1099 Models
In practice, many legal teams prefer hourly or fixed-fee contractor structures for healthcare sales support because those models are easier to align with "set in advance" and "not volume/value linked" principles.
That does not make hourly arrangements automatically compliant. It does make the compensation logic cleaner to defend in many scenarios.
| Commission-based 1099 | Hourly 1099 | |
|---|---|---|
| Compensation linked to referral volume/value | Often yes | Typically no |
| Safe-harbor posture complexity | Higher | Lower in many structures |
| Need for FMV documentation | High | High |
| Need for legal review | Required | Required |
The Parallel Risk Most Teams Forget: Worker Classification
AKS is only one lane of risk. Worker classification can become a second lane quickly.
If a "contractor" is supervised like a W2 employee in day-to-day reality, tax and labor exposure can stack on top of AKS concerns. That overlap is one reason counsel often reviews contract language and operating behavior together.
What a Legal Team Usually Wants to See
At minimum, expect your legal and compliance reviewers to ask for:
- A written services agreement with defined scope and term
- Compensation methodology documented in advance
- Fair-market-value support for rates
- Operational boundaries that avoid ambiguous clinical-influence behavior
- A monitoring plan that matches contract terms to actual field practice
If those basics are missing, your compliance posture is fragile before the first call is made.
Practical Bottom Line for Commercial Leaders
You do not need to avoid contractor models. You do need to structure them deliberately.
The teams that stay out of trouble make compensation architecture a pre-launch decision, not a post-growth patch.

Tell us about your needsFrequently Asked Questions
Did 2025 case law make commission-based 1099 healthcare sales models automatically safe?
No. Sorensen and Marchetti added fact-specific nuance. They did not remove AKS risk or safe-harbor analysis requirements.
Is hourly billing automatically compliant under AKS?
No. Hourly models are often cleaner to analyze, but legal review, contract quality, and fair-market-value support still matter.
Which statutes and regulations should legal teams review first?
Start with 42 U.S.C. § 1320a-7b(b) and 42 C.F.R. § 1001.952(d), then evaluate relevant case law and OIG guidance in your fact pattern.
Why include worker classification review in a 1099 compliance workflow?
Because contractor misclassification risk can overlap with AKS compensation risk, creating additional tax and labor exposure.
