Part 2: Ambulatory Surgery Centers (ASCs): The Nuts and Bolts and Legal Requirements

Episode Date: March 18, 2025

In Part 2 of this Stark Integrity discussion, Bob Wade (Captain Integrity) continues his breakdown of Ambulatory Surgery Centers (ASCs)—moving beyond foundational concepts to focus on:

Ownership structures, operational requirements, and key compliance risks.

While Part 1 introduced the ASC framework and the distinction from Stark Law, Part 2 emphasizes:

How to structure and operate ASCs in a compliant and defensible manner.

Revisiting the Regulatory Framework

As a reminder, ASCs remain unique in that:

• Stark Law does not apply
• The Anti-Kickback Statute (AKS) governs compensation and ownership relationships

This creates an environment where:

Intent, structure, and safeguards are critical.

The focus therefore shifts to:

• Meeting safe harbor requirements
• Demonstrating legitimate business purpose
• Avoiding referral-driven arrangements

The Importance of ASC Safe Harbors

The episode dives deeper into the role of AKS safe harbors specific to ASCs.

These safe harbors are designed to ensure that:

• Physician ownership reflects actual participation
• Returns are tied to investment—not referrals
• Arrangements are commercially reasonable

Depending on the ASC structure, different safe harbors may apply, including:

• Surgeon-owned ASCs
• Single-specialty ASCs
• Multi-specialty ASCs
• Hospital/physician joint ventures

The takeaway:

Each structure must be carefully evaluated against the applicable safe harbor criteria.

The “One-Third” Tests—A Closer Look

Part 2 expands on the “one-third” tests introduced in Part 1.

These tests are used to confirm that physician investors:

• Perform a meaningful portion of their procedures at the ASC
• Derive a sufficient portion of their practice income from those services

The goal is to ensure:

Physicians are active participants—not passive investors benefiting from referrals.

Failure to meet these thresholds can create:

• Increased AKS risk
• Questions about the legitimacy of ownership
• Exposure under enforcement scrutiny

Ownership and Investment Considerations

Ownership in ASCs must be structured carefully to avoid:

• Disguised referral payments
• Unequal distributions lacking justification
• Incentives tied to volume or value of referrals

Investors should:

• Make bona fide capital contributions
• Receive returns proportional to ownership
• Participate in the operations of the ASC

The key point:

Ownership must reflect real investment and real involvement.

Operational Risk Areas

Part 2 also highlights several operational risks that can trigger compliance concerns:

Case Scheduling and Block Time

Preferential scheduling may:

• Favor certain physicians
• Create indirect incentives tied to referrals

Resource Allocation

Unequal access to equipment or operating rooms may raise fairness and compliance questions.

Volume Patterns

Unusual increases in procedures tied to ownership can attract scrutiny.

The takeaway:

Operational decisions can carry legal consequences.

Documentation and Oversight

As with most compliance areas, documentation is essential.

Organizations should maintain:

• Clear ownership agreements
• Records of physician participation
• Support for distributions and returns

Ongoing oversight should include:

• Monitoring physician activity
• Reviewing compliance with safe harbor requirements
• Evaluating changes in volume and patterns

Because:

What you cannot document, you cannot defend.

Common Pitfalls

The episode identifies several common mistakes:

Treating ASCs as Low-Risk

Assuming that Stark’s inapplicability reduces overall compliance exposure.

Ignoring Safe Harbor Details

Failing to meet specific technical requirements of AKS protections.

Passive Ownership Models

Allowing physicians to invest without meaningful participation.

Lack of Monitoring

Not reassessing compliance over time as operations evolve.

The takeaway:

ASC compliance failures are often preventable with proper structure and oversight.

Practical Compliance Considerations

Organizations should:

• Evaluate ASC structures against applicable AKS safe harbors
• Ensure physician investors meet participation requirements
• Align ownership and returns with legitimate investment principles
• Monitor operational practices for fairness and consistency
• Maintain strong documentation and review processes

Because:

Compliance is driven by both structure and day-to-day execution.

Key Takeaways

• ASCs are governed by the Anti-Kickback Statute rather than Stark Law
• Safe harbors provide the framework for compliant structures
• The “one-third” tests ensure meaningful physician participation
• Ownership must reflect real investment—not referral generation
• Operational practices can create compliance risk
• Documentation and ongoing oversight are essential
• Many ASC risks arise from execution—not design

Final Thoughts

Part 2 reinforces a critical principle in healthcare compliance:

Structure alone is not enough—execution determines compliance.

ASCs offer significant opportunities for:

• Efficiency
• Collaboration
• Innovation

But they also require:

Careful alignment of ownership, operations, and regulatory requirements.

Ultimately:

The difference between a compliant ASC and a risky one lies in the details—how it is structured, how it operates, and how it is monitored over time.
