If you’re a physician or practice manager, Stark Law is one of the easiest ways to accidentally put your practice at risk. It doesn’t require intent—just the existence of a financial relationship tied to referrals can trigger a violation. That means everyday business decisions like ownership, compensation, or referral workflows can create compliance exposure without you realizing it.

The Centers for Medicare & Medicaid Services (CMS) enforces Stark Law to prevent improper financial influence in medical decision-making. If your practice bills Medicare or Medicaid, this applies directly to you. Understanding how this law works is critical to protecting both your revenue and your reputation.

What Stark Law Actually Prohibits (In Plain English)

Stark Law—also called the Physician Self-Referral Law—prohibits you from referring patients for certain services to an entity where you or your immediate family has a financial relationship. This includes both ownership interests and compensation arrangements. If that entity bills Medicare or Medicaid, the referral could be prohibited.

Here’s the key point most practices misunderstand: Stark Law is strict liability. That means even if you didn’t intend to break the law, you can still be penalized.

This is why even well-meaning arrangements—like profit-sharing or referral convenience—can become serious compliance issues if not structured properly.

What Counts as Designated Health Services (DHS)

Stark Law only applies to specific services—but these services represent major revenue streams for most practices. That’s why DHS is where your highest risk exists.

Common DHS categories include:

• Clinical lab services
• Imaging (MRI, CT, X-ray)
• Physical therapy
• Durable medical equipment (DME)
• Outpatient prescription drugs
• Hospital services

If your practice refers patients for these services and there’s a financial connection—even indirectly—you must evaluate compliance immediately. Many violations occur because practices overlook indirect ownership or family relationships.

What Is a “Financial Relationship” Under Stark Law?

A financial relationship doesn’t just mean ownership—it includes any form of compensation or value exchange. This can include salaries, bonuses, lease agreements, medical directorships, or consulting fees.

There are two main categories:

• Ownership or investment interest
• Compensation arrangements

Even seemingly standard agreements can trigger violations if they are not structured correctly.

The risk increases when compensation is tied—directly or indirectly—to referral volume. This is one of the most common issues identified in audits.

Key Stark Law Exceptions You Must Understand

Not all financial relationships are prohibited—but they must meet strict exceptions. These exceptions are highly specific and must be followed exactly.

Common exceptions include:

• Bona fide employment relationships
• Personal service agreements
• Office or equipment leases
• In-office ancillary services

If even one element of an exception is missing—such as written documentation or fair market value—you may still be non-compliant. This is where many practices unknowingly fail.

Common Stark Law Mistakes That Trigger Audits

Most violations don’t come from fraud—they come from poor documentation and oversight. That’s why Stark Law is so dangerous for busy practices.

Watch for these red flags:

• Missing or expired contracts
• Compensation not set in advance
• Payments exceeding fair market value
• Informal referral arrangements

If your agreements haven’t been reviewed in the last 12–24 months, there’s a strong chance they need attention.

Action Steps to Stay Compliant

To protect your practice, you need a proactive approach—not a reactive one.

Start with these steps:

• Audit all financial relationships and referrals
• Ensure all agreements are written and current
• Validate fair market value and commercial reasonableness
• Confirm every arrangement meets a Stark exception

Practices that take these steps early reduce audit risk significantly and maintain cleaner revenue cycles.
