The Oncology Care Model (OCM) aims to transform oncology practices by implementing an episode-based total cost of care payment model for chemotherapy, involving multiple payers including Medicare. Eligible practices include various types of physician groups and are required to adhere to six practice requirements while reporting data to CMS quarterly. Payments are structured as standard Medicare FFS combined with additional funding for enhanced care management and performance-based incentives based on cost reductions and quality benchmarks.
