A charge description master (CDM) or chargemaster analyst maintains the list of billable services for a hospital. As a CDM analyst, job duties include creating patient charge description documents based on coded medical records, training clinical staff in coding procedures, and making sure coding and charge descriptions are compliant with industry standards, legal mandates, and reporting requirements. The accuracy of medical coding, charge descriptions, and hospital rates, as well as maximizing insurance reimbursements and patient cash-pay, are other responsibilities.
