They make sure that patient charts are coded correctly for reimbursement.

Health Information Managers oversee the overall management of health information systems and departments but do not typically perform hands-on chart coding for reimbursement.

Coders and reimbursement specialists review clinical documentation and apply standardized code sets such as ICD-10-CM, CPT, and HCPCS to diagnoses and procedures. Accurate coding directly determines the reimbursement amount received from payers, making this role central to the revenue cycle management process.

Cancer Registrars collect and maintain data specifically on cancer diagnoses and treatment for research and reporting purposes, not for general reimbursement coding.
