Group practice

A group practice is a business and legal structure, not just several clinicians under one roof. The structure determines who shares staff, billing and policies, and who carries HIPAA obligations. Outside one area of federal law, the term has no single legal definition.

What is a group practice?

A group practice is a medical practice in which two or more clinicians provide care and bill through one shared business entity, with common ownership, staff and administrative operations.

Common forms:

• Single-specialty group: clinicians in one specialty, such as a four-physician dermatology practice.
• Multispecialty group: several specialties in one entity, for example family medicine, cardiology and orthopedics billing under one organization.
• Group private practice: a group owned by its clinicians rather than by a hospital or health system.

Two variants appear in contracts and industry writing:

• Group practice without walls: clinicians keep separate offices but combine ownership and back-office functions such as billing, purchasing and HR into one entity.
• Functional group practice: a group that operates as one unified business, a phrasing often linked to federal self-referral rules.

Outside federal physician self-referral rules, "group practice" is industry usage. It has no single legal definition. For related terms, see the healthcare operations glossary.

In practice at a clinic or small practice

At the front desk, a group practice usually means one phone line, one scheduling system and one intake process serving several clinicians, and often several locations. Staff book patients across providers. When one clinician's schedule fills, they can offer another clinician in the group. Front desk staff also cover for each other across sites when someone is out.

The office manager or practice administrator runs the shared functions. These include payroll, credentialing and payer enrollment for each clinician, shared policies and staff training, and supply ordering. In a group without walls, the same procedure changes have to reach every site at the same time. A new check-in step or an updated records-request process can't live in one office's binder. Groups handle this with written procedures and a shared staff channel for updates. The operations library for practice managers covers how to document and roll out shared procedures across sites.

What the rules say

• Stark Law (physician self-referral): Here "group practice" has a formal definition. The requirements address points such as a single legal entity, a minimum number of physicians, a unified business, and how profits and productivity bonuses may be shared.
• Medicare enrollment: The group enrolls as an organization, and each clinician reassigns their Medicare benefits to the group.
• HIPAA: A group practice that conducts standard electronic transactions, such as electronic claims, is generally a covered entity. It is responsible for HIPAA compliance across all its locations and staff.
• Affiliated covered entities: Separate legal entities under common ownership or control may designate themselves as a single covered entity for HIPAA purposes.

Whether a specific arrangement qualifies as a group practice under Stark or Medicare rules is a question for healthcare counsel. This page is a staff-level overview, not legal advice.
