Group Practice Part 2: Stark Law’s In-Office Ancillary Services Exception
Episode Date: May 4, 2022
In this episode of Stark Integrity, host Bob Wade (“Captain Integrity”) continues the group practice series by focusing on one of the most important—and widely relied upon—exceptions under the Stark Law: the in-office ancillary services (IOAS) exception.
If Part 1 established the foundation of what qualifies as a group practice, this episode explains why that definition matters so much—because it unlocks access to this critical exception.
What Is the In-Office Ancillary Services Exception?
The IOAS exception allows physicians within a properly structured group practice to refer patients for designated health services (DHS) that are provided within the same group.
These services can include:
- Imaging
- Laboratory services
- Certain outpatient services
Without this exception, many routine internal referrals would be prohibited under the Stark Law.
Why This Exception Is So Important
This episode reinforces that the IOAS exception is central to how many healthcare organizations operate. It enables:
- Integrated care within a group practice
- Convenience for patients
- Operational efficiency
However, the exception is only available if the organization fully meets the Stark Law definition of a group practice.
Key Requirements
Bob highlights that the IOAS exception is highly technical and requires strict compliance with several elements:
Same Building or Centralized Building
Services must generally be provided in the same building where the physician practice operates, or in a qualifying centralized location.
Supervision Requirements
Services must be supervised appropriately by a physician within the group, consistent with Stark and billing requirements.
Billing Requirements
The group practice—or an entity wholly owned by the group—must bill for the services.
Group Practice Status
Most importantly, the organization must meet the full Stark definition of a group practice, as discussed in Part 1.
The Link to Compensation
A major theme in this episode is how the IOAS exception connects to physician compensation and profit distribution.
Group practices are allowed to distribute profits from ancillary services, but only if those distributions:
- Do not directly take into account the volume or value of referrals
- Follow Stark-compliant methodologies
- Are applied consistently across the group
Improper distribution methods are a common source of compliance risk.
Common Pitfalls
This episode highlights several areas where organizations can run into trouble:
- Failing to meet the technical definition of a group practice
- Structuring profit distributions in a way that rewards referrals
- Providing services outside of qualifying locations
- Misunderstanding supervision or billing requirements
Because the IOAS exception is so central, mistakes in these areas can have significant downstream consequences.
Practical Takeaways
The key takeaway from this episode is that the IOAS exception is powerful—but narrow. Healthcare organizations should:
- Confirm they meet the Stark definition of a group practice
- Carefully structure ancillary service arrangements
- Review compensation and distribution models for compliance
- Ensure documentation aligns with operational reality
These steps help protect access to the exception and reduce regulatory risk.
Final Thoughts
This episode reinforces why group practice and the IOAS exception are so closely linked. Together, they form a cornerstone of Stark Law compliance for many organizations.
When structured properly, they support integrated care and operational efficiency. When structured incorrectly, they can expose organizations to significant compliance issues.
For healthcare leaders and compliance professionals, mastering the IOAS exception is essential—and it all starts with getting the group practice structure right.
