Article Overview

This article covers the Stark Law group practice “substantially all” test, including how the requirement is measured, what kinds of documentation may be relevant, and when limited reprieve periods may apply. It also contrasts this test with a closely related 75% group-service standard and discusses the role of Health Professional Shortage Areas (HPSAs). The content is aimed at physicians, group practice administrators, compliance staff, and medical billing/coding professionals who need a high-level understanding of physician self-referral compliance concepts.

Why This Topic Matters

Understanding this requirement helps physician groups evaluate whether their practice structure and service patterns fit within Stark Law group practice rules and related exceptions. It is relevant for compliance review, documentation readiness, and organizational planning.
