This document describes an initiative by Catholic Health East (CHE) to implement system-wide Medicare compliance standards across their network of hospitals. A task force developed 12 standards of practice focused on accurate patient status determination and communication between case management, billing, and other departments. A large teaching hospital pilotted the standards, which improved billing timeliness and reduced aged Medicare accounts. All CHE hospitals were then required to implement the standards within 3 months. The standards addressed issues like physician-led utilization reviews, concurrent case management, electronic communication, and data analysis. Overall the goal was to promote early and accurate status assessments to support compliant billing and reimbursement.
