Revenue Cycle Management (RCM) in medical billing refers to the financial process that healthcare facilities use to track patient care episodes from registration and appointment scheduling to the final payment of a balance. It includes billing, coding, claims processing, and collections to ensure maximum reimbursement for services provided. Effective RCM improves cash flow, reduces claim denials, and enhances patient satisfaction. It involves multiple departments working together to manage clinical and administrative functions. Overall, RCM is crucial for maintaining the financial health of healthcare organizations.
