The 2025 Black Book^TM Outsourced Laboratory, Radiology, and Cross-Ancillary RCM Report captures a pivotal year of operational and reimbursement change across outpatient services. Drawing on 3,275 validated users, the report ranks vendors on 18 KPIs and highlights how leading partners are helping organizations navigate expanding payor requirements, rising documentation burdens, and growing patient-pay expectations.

Key Highlights
