Percentage Arrangements under the Stark Law

Episode Date: June 5, 2024

In this episode of Stark Integrity, Bob Wade (Captain Integrity) explores another commonly used—but highly nuanced—compensation methodology:

Percentage-based arrangements under the Stark Law.

While percentage arrangements may appear simple in concept, their application under Stark is highly context-dependent, with clear distinctions between where they are permitted—and where they are prohibited.

What Is a Percentage Arrangement?

A percentage arrangement is a compensation structure where:

Payment is based on a percentage of revenue, collections, or another financial metric.

Examples include:

• Percentage of professional collections
• Percentage of service line revenue
• Percentage-based management fees

These models are widely used in healthcare because they:

• Align incentives
• Scale with performance
• Provide operational flexibility

But under Stark:

Not all percentage arrangements are treated the same.

Where Percentage Arrangements May Be Permissible

As discussed in the episode, percentage-based compensation can be permissible when:

• It is tied to personally performed services
• It reflects fair market value (FMV)
• The arrangement is commercially reasonable (CR)
• Compensation is not determined in any manner that takes into account referrals

This is why percentage models are often seen in:

• Physician compensation based on their own work
• Certain service arrangements where value is directly tied to performance

The key concept:

Percentage arrangements tied to a physician’s own services are generally more defensible.

Where Percentage Arrangements Are Prohibited

The Stark Law and regulations specifically limit or prohibit percentage-based compensation in certain contexts—particularly:

• Office space leases
• Equipment leases

In these scenarios, percentage arrangements are problematic because:

They can directly reflect referral volume or downstream revenue.

For example:

• A percentage of revenue generated from services performed in leased space
• A percentage tied to utilization of leased equipment

These structures raise concerns because they:

Create a direct link between compensation and referrals or services generated from those referrals.

Percentage vs. Percentage Points

A helpful distinction highlighted in the episode is the difference between:

• Percentage (e.g., 20% of revenue)
• Percentage points (e.g., a 5% increase based on certain criteria)

While both involve percentages, the compliance analysis depends on:

What the percentage is tied to—and why.

Even seemingly minor structuring differences can significantly impact compliance.

The “Determined In Any Manner” Standard

As with other Stark analyses, the critical issue is not just the use of a percentage—but:

Whether compensation is “determined in any manner” that takes into account referrals.

This is a broad and strict standard.

It means:

• Even indirect connections to referral volume can create risk
• Design choices matter as much as payment outcomes
• The rationale behind the percentage must be defensible

The takeaway:

You cannot rely on the form of the arrangement—you must evaluate its substance.

Common Misconceptions

The episode addresses several common misunderstandings:

• Myth: Percentage arrangements are always prohibited
  • Reality: They are permitted in certain contexts
• Myth: Percentage equals volume/value violation
  • Reality: Only when tied to referrals or downstream business
• Myth: If it’s common in the market, it must be compliant
  • Reality: Market practice does not equal regulatory compliance

These misconceptions often lead to overconfidence in high-risk structures.

Practical Compliance Considerations

From an operational standpoint, organizations should:

• Identify what the percentage is based on
• Evaluate whether it reflects personally performed services or referrals
• Avoid percentage structures tied to leased space or equipment revenue
• Ensure the arrangement meets FMV and CR
• Document the reasoning behind the compensation model

Because ultimately:

Percentage arrangements require careful structuring—not assumptions of safety.

Key Takeaways

• Percentage arrangements are not inherently prohibited — context determines permissibility
• They are generally acceptable when tied to personally performed services
• They are often prohibited in lease arrangements — especially space and equipment
• The “determined in any manner” standard applies — referral influence creates risk
• Structure and rationale matter more than form
• Market practice does not guarantee compliance
• Careful analysis and documentation are essential

Final Thoughts

This episode reinforces a broader theme across Stark Law compliance:

The same compensation tool can be either compliant or problematic depending on how it is used.

Percentage arrangements offer flexibility and alignment—but they also introduce risk when tied to the wrong metrics or structured without sufficient analysis.

Organizations must go beyond surface-level assumptions and ask:

• What is this percentage actually measuring?
• Is it tied to services—or referrals?
• Can we clearly explain how this was determined?

Because in practice:

Percentage-based compensation is not defined by the percentage itself—but by what drives it.
