The HHS Office of Inspector General issued Advisory Opinion No. 26-02, a favorable opinion concluding that a Management Service Organization (MSO) could own and operate an independent clinical laboratory that accepts referrals from affiliated urgent care centers without implicating the federal Anti-Kickback Statute (AKS). The opinion focuses on three remuneration guardrails: no provider compensation tied to lab referral volume, no remuneration flowing from the lab to the urgent care centers, and no payment to centers or providers from laboratory revenue. The opinion provides instructive compliance guidance for MSOs, urgent care clinics, and clinical laboratories pursuing integrated care models.
