On April 23, 2026, OIG updated its General Questions Regarding Certain Fraud and Abuse Authorities FAQ page — its first update since July 2024 — with two additions that carry direct and significant implications for concierge and cash-based practice models. These updates do not change the law; they clarify and reaffirm OIG’s longstanding interpretive positions on two points that have become the subject of dangerous industry overreliance. Every physician or administrator who has received compliance assurance based primarily on Stark Law documentation or FMV analysis should treat these FAQs as a direct communication from the enforcement agency.
Revised FAQ No. 4 — Stark Law Compliance Is Not AKS Protection
A persistent misconception in health care transactions is that because many Stark Law exceptions and AKS safe harbors share overlapping elements — written agreements, FMV compensation, term requirements — satisfying a Stark exception functionally satisfies the AKS as well. Revised FAQ No. 4 explicitly and unequivocally rejects this position.
OIG’s revised FAQ emphasizes several foundational distinctions between the two statutes. The Stark Law is a strict-liability civil statute: it does not require proof of intent, and its exceptions are technical and precise. The AKS is an intent-based criminal statute that requires knowing and willful conduct and evaluates arrangements through the lens of the parties’ motivations. An arrangement can satisfy every technical element of a Stark exception — proper written agreement, FMV compensation, one-year term, services documented in advance — and still violate the AKS if the intent underlying the arrangement is to generate referrals.
For hybrid concierge practices that have relied on Stark compliance documentation as their primary compliance defense — particularly those using the personal services exception under 42 C.F.R. § 411.357(d) for management arrangements, physician extender contracts, or employer agreements — this FAQ is a direct call to action. Stark compliance is necessary but not sufficient. A separate AKS intent analysis, safe harbor evaluation, and documentation of commercial reasonableness are independently required.
New FAQ No. 17 — Fair Market Value Is Not a Safe Harbor
FAQ No. 17 may be the more consequential of the two updates for the concierge medicine field. OIG addressed and firmly rejected the widely held industry position that compensation set at fair market value — established through an independent third-party valuation — provides a complete defense to AKS liability. The OIG’s answer is unequivocal: “an arrangement may violate the AKS even where remuneration is consistent with FMV.”
OIG’s reasoning is textually precise: the phrase “fair market value” does not appear in the text of the AKS itself. It appears only in certain regulatory safe harbors as one of several elements required for safe harbor protection. A party that satisfies the FMV element of a safe harbor but fails to satisfy other required elements — a written agreement, a one-year term, compensation set in advance, services not exceeding commercial necessity — has not achieved safe harbor protection, regardless of how thorough its FMV analysis was.

Practices that have relied solely on a valuation firm’s FMV opinion letter to validate their MSO management fees, lab service agreements, physician advisory arrangements, or employer contracts must immediately conduct a full safe harbor analysis. FMV is a component of compliance — not a destination.
April 2026 OIG FAQ No. 17 — Direct Implication for Concierge Practices
For concierge practices and DPC models, this FAQ carries immediate practical consequences. MSO management fee structures that have been validated by FMV analysis alone, without confirmation that the arrangement satisfies each element of the personal services safe harbor, remain legally exposed. Lab relationships supported by invoiced pricing at market rates, without a full discount safe harbor analysis, are not protected. Employer contracts priced at FMV without evaluation of the referral nexus and intent elements remain subject to AKS scrutiny. The April 2026 FAQ updates make clear that the enforcement agency views FMV as a best practice and a compliance input — not a compliance output.
Conclusion
In summary, the recent OIG FAQs clarify that Stark Law compliance is not interchangeable with AKS protection, and fair market value alone is not a safe harbor. Concierge and DPC practices must recognize that strict adherence to technical requirements under Stark or FMV guidelines does not guarantee immunity from AKS scrutiny. Instead, a comprehensive compliance approach is essential—one that incorporates an intent-based analysis, safe harbor evaluation, and thorough documentation of commercial reasonableness. These updates underscore the importance of proactively reviewing all arrangements to ensure full regulatory alignment and mitigate legal risk.
Key Takeaways
- Stark Law and AKS are fundamentally distinct statutes; satisfying one does not automatically satisfy the other.
- AKS requires proof of intent, and arrangements can violate AKS even if they meet every Stark exception.
- Fair market value, though important, is only one element of AKS safe harbor protection—not a complete defense.
- Concierge practices must conduct a full safe harbor analysis, including intent, written agreements, term requirements, and commercial necessity.
- Regulatory updates demand active, ongoing compliance efforts to ensure all contractual arrangements withstand OIG scrutiny and enforcement actions.
