Hospital Billing RCM (Revenue Cycle Management) is the end-to-end financial process from patient registration through payment collection. The cycle includes: pre-registration insurance verification, charge capture during visit, medical coding (ICD-10, CPT, modifiers), claim submission to payers, denial management, follow-up, and final payment posting. RCM specialists manage this pipeline to maximize clean claim rates, minimize denials, and accelerate cash collection. They work with coding teams, billing staff, patient accounting, and payer liaisons. Competence requires fluency in coding standards, payer contracts, and claim management software.
