Forming business relationships is part of running a successful medical practice. You may hire another physician, lease office space, work with a marketing company, or bring on a medical director. Each of these decisions can help your practice grow, but they can also raise important compliance questions.
One of the most common concerns physicians have is whether a financial relationship could violate Stark Law or the Anti-Kickback Statute.
The good news is that not every financial relationship is prohibited. Many common business arrangements are allowed when they meet specific legal requirements known as Stark Law exceptions.
This guide explains how Stark Law exceptions apply to common practice operations, what situations deserve extra attention, and when it’s time to seek professional guidance.
The federal Stark Law generally prohibits physicians from referring Medicare or Medicaid patients for certain designated health services (DHS) to an entity with which they or an immediate family member have a financial relationship.
That sounds broad—and it is.
However, Congress recognized that many legitimate business relationships are necessary for healthcare organizations to operate. As a result, the law includes numerous exceptions that allow specific arrangements when they satisfy detailed requirements.
Meeting one requirement is not enough. An arrangement must satisfy every element of the applicable exception, including documentation, compensation, and operational requirements.

Many physicians don’t worry about compliance until they’re preparing to sign an agreement. Below are some of the most common situations where Stark Law exceptions may apply.
Hiring an employed physician is one of the most common, and generally permissible, financial relationships.
The employment exception allows physician compensation arrangements that meet specific requirements, including:
Compensation that reflects fair market value
Payment that is commercially reasonable
Productivity incentives that comply with Stark requirements
Compensation that is not based on the value or volume of referrals for designated health services
Before finalizing an employment agreement, review both the compensation structure and any bonus formulas to confirm they align with current regulations.
Medical directorships and consulting agreements can provide valuable expertise, but they require careful documentation.
A compliant arrangement typically includes:
A written agreement signed by both parties
Clearly defined responsibilities
Compensation set in advance
Payment that reflects fair market value
Services that support a legitimate business need
Agreements that appear to pay for referrals rather than actual services can create significant compliance concerns.
Many healthcare organizations lease office space, medical equipment, or diagnostic equipment from other providers.
These arrangements often qualify under Stark Law exceptions when they include:
A written lease agreement
A defined lease term
Fair market rental rates
Commercially reasonable business terms
Offering free or heavily discounted space without a valid business justification may increase compliance risk.
Marketing is an area where physicians often have questions.
Hiring a marketing agency, advertising online, or investing in patient outreach is generally permissible. Problems arise when compensation becomes tied directly to referrals or federally reimbursed patient volume.
Examples that deserve careful review include:
Paying for patient referrals
Referral fees
Compensation based on the number of referred patients
Revenue-sharing arrangements tied to designated health services
Many of these arrangements also require evaluation under the federal Anti-Kickback Statute.
Physicians often compensate one another for services that have nothing to do with patient referrals.
Examples include:
Call coverage
Administrative leadership
Teaching
Consulting
Practice management responsibilities
These arrangements are often appropriate when compensation reflects actual work performed, is supported by documentation, and represents fair market value.
Many medical practices provide additional services such as:
Imaging
Laboratory testing
Physical therapy
Other designated health services
Certain in-office ancillary services may qualify under specific Stark Law exceptions, but the rules are highly technical. Practice ownership structure, supervision requirements, and billing practices all play a role in determining compliance.
As practices expand their service offerings, it’s important to evaluate these arrangements before implementation rather than after problems arise.
Not every agreement creates compliance concerns. However, certain situations should prompt additional review before anything is signed.
Watch for arrangements involving:
Compensation tied to patient referrals
Verbal agreements with no written contract
Compensation significantly above or below fair market value
Free office space or equipment
Revenue-sharing models involving designated health services
Vague job duties or consulting responsibilities
Agreements that seem difficult to explain to an outside reviewer
If an arrangement seems unusually generous or exists primarily because one party refers patients to another, it’s worth consulting experienced healthcare counsel before moving forward.
One of the biggest sources of confusion is the difference between Stark Law exceptions and Anti-Kickback safe harbors.
Although the terms are often used interchangeably, they apply to different federal laws.
Stark Law exceptions determine whether certain physician financial relationships are permitted under the Stark Law.
Anti-Kickback safe harbors describe arrangements that receive protection under the federal Anti-Kickback Statute when all applicable requirements are met.
Many business relationships should be evaluated under both laws. Satisfying a Stark Law exception does not automatically satisfy an Anti-Kickback safe harbor, and vice versa.
Before entering a new financial relationship, ask these questions:
Is there a written agreement?
Is compensation based on fair market value?
Are the services clearly defined?
Would this arrangement make business sense even if no referrals occurred?
Is compensation unrelated to the volume or value of referrals?
Have the appropriate compliance or legal professionals reviewed the agreement?
Answering these questions early can help reduce risk and avoid costly changes later.
Most physician business relationships are entirely legitimate. The challenge is making sure they’re structured correctly from the beginning.
Whether you’re hiring providers, expanding services, leasing equipment, or forming strategic partnerships, understanding Stark Law exceptions can help you make informed decisions while protecting your practice.
If your practice is preparing for growth, new partnerships, or operational changes, proactive planning today can help prevent compliance challenges tomorrow.
