Quality Assurance and Provider Review
The MassHealth agency conducts reviews of providers and administers quality-control
programs to ensure that MassHealth members are receiving high-quality medical services. An
independent clinical laboratory must maintain its own quality-control program and successfully
participate in one or more proficiency testing programs that cover all Medicare-certified
specialties and subspecialties of the laboratory. The laboratory must make the results of the
proficiency testing programs available to the MassHealth agency and the Attorney General’s
Medicaid Fraud Division upon request or during an on-site visit.
