Q: What is an “Aggregation?”

A: An aggregation is the partnership of multiple physician groups under one group name and tax identification number but allowing each group to operate independently as its own separate division.

Q: How is an Aggregation different from a merger?

A: Aggregation differs from a merger, as practices join as a Division of a Group practice on equal footing, retaining division autonomy, decision making, and care center culture but establishing a collaborative centralized governance infrastructure. In contrast, in a merger one entity typically is dominant, looking to have the other adopt its infrastructure. In both situations, two companies come together to benefit from combined resources, but under different premises.

Q: Will I keep my same doctor(s)?

A: Yes. You will still be able to see the same orthopedic and musculoskeletal specialists. There will be no changes to your doctor(s).

Q: How will I reach my doctor or clinic, request/change an appointment, or make a billing inquiry?

A: There will be no change to how you can contact our offices. To reach your doctor or clinic, to request /change an appointment, or make a billing inquiry, visit or call 815-398-9491.
