ASC Safe Harbors and Physician Investors in ASCs: Managing Lower-Volume Owners
ASC safe harbors play a central role in evaluating ownership arrangements involving Physician Investors in ASCs. Ambulatory surgery centers frequently confront difficult questions about how to address physician-investors who perform fewer procedures at the center than their co-investors. These situations can create political and operational tension, particularly when higher-volume physicians believe lower-volume investors are benefiting from profits generated by more active users of the facility. If not handled carefully, that tension can lead to decisions that implicate the federal anti-kickback statute, which prohibits offering or maintaining investment opportunities based on the actual or expected volume or value of referrals.

This article explains how ASC safe harbors affect the treatment of Physician Investors in ASCs, particularly when some investors generate materially fewer procedures than others. The key issue is how an ASC can address ownership, redemption, and participation concerns without creating the appearance that investment rights depend on referral volume.
Why ASC Safe Harbors Are Counterintuitive Applied to Physician Investors in ASCs
The anti-kickback statute standards that apply to ambulatory surgery center ownership are somewhat counterintuitive. Unlike many other health care arrangements, ASC safe harbors for investment interests include conditions tied to the physician-investor’s use of the facility. In that context, referral-related thresholds are intended to help identify whether the ASC functions as a natural extension of the physician’s medical practice.
ASC safe harbors are not the only way to evaluate compliance risk. A physician who does not satisfy every safe harbor threshold may still legitimately use the ASC as an extension of his or her office practice. The safe harbor provides a pathway to more certain protection when all conditions are met, but failure to satisfy a threshold does not automatically mean the arrangement is unlawful.
Evaluating Lower-Volume Physician Investors in ASCs
When Physician Investors in ASCs do not meet the specific requirements of an ASC safe harbor, the center should still conduct a complete facts-and-circumstances analysis. A physician may practice in a specialty or subspecialty that naturally produces fewer ASC procedures than other specialties represented at the center. Lower procedural volume alone does not necessarily indicate greater anti-kickback risk than a physician who comes closer to satisfying the ASC safe harbors.
Depending on the practice type, a lower level of referrals may still be consistent with genuine use of the ASC as an extension of the physician’s practice. This may be frustrating to higher-volume surgeons, especially when they believe the center’s profitability is driven disproportionately by their procedures. However, using one-third tests or other volume-based metrics as a mechanism to exclude lower-volume Physician Investors in ASCs can create significant compliance concerns if the practical effect is to pressure investors to increase referrals.
ASC Safe Harbors, Forced Redemption, and Regulatory Risk
Excluding or redeeming Physician Investors in ASCs because they do not meet ASC safe harbor thresholds can create substantial legal risk. These actions may be challenged by excluded investors or reviewed by government enforcement agencies, particularly if the facts suggest that ownership was conditioned on generating additional procedures for the ASC.
Once physicians own interests in an ASC, it is difficult to force redemption without creating an inference that continued ownership depends on referral volume. Great care should be taken to ensure that frustration among higher-volume producers does not drive actions that increase regulatory exposure for the center, its owners, Physician Investors in ASCs, or its governing body.
Operating Agreement Considerations for Physician Investors in ASCs
Operating agreements that govern ASC ownership can themselves create compliance risk if exclusion or redemption provisions are tied too closely to referral-related criteria. Procedures for addressing investor eligibility should be established in advance, applied uniformly, and drafted to avoid any inference that Physician Investors in ASCs must generate additional referrals to maintain an investment interest.
Efforts framed as bringing investors closer to ASC safe harbors can easily be turned inside out and characterized as requiring additional referrals. For that reason, ASC governing documents and enforcement practices should be reviewed carefully before any action is taken against a lower-volume physician-investor.
Key Compliance Principle for ASC Safe Harbors
ASC safe harbors are intended to protect arrangements that present a lower risk of abuse when all specified conditions are satisfied. They were not designed to replace a complete risk analysis for Physician Investors in ASCs who fall outside one or more safe harbor elements. This distinction is especially important because the ASC safe harbor is unusual: it incorporates use-related thresholds in a legal framework that otherwise prohibits conditioning financial benefits on referrals.
In many other safe harbor contexts, structuring an arrangement to come close to safe harbor protection can be a valid risk-mitigation strategy. That approach does not translate neatly to ASC ownership. Requiring Physician Investors in ASCs to increase procedures in order to satisfy ASC safe harbors may itself invoke the referral prohibition. Forcing a physician out of the ASC solely because the physician does not meet a safe harbor threshold can therefore create significant anti-kickback risk.
Conclusion
ASC leaders should evaluate lower-volume Physician Investors in ASCs with caution, consistency, and a documented facts-and-circumstances analysis. While ASC safe harbors provide important compliance benchmarks, they should not be applied mechanically to force referrals or justify redemption. A careful, uniformly applied process helps address ownership concerns while reducing anti-kickback risk.
