The function of a medical coder is to translate healthcare diagnoses, procedures, and services into universal codes. This process involves assigning specific numerical and alphanumeric codes to medical diagnoses and procedures based on standardized coding systems, such as ICD-10 (International Classification of Diseases) and CPT (Current Procedural Terminology). This coding is essential for various reasons, including billing and reimbursement from insurance companies, maintaining accurate medical records, and enabling the collection of health statistics for research and public health purposes. By creating this coded documentation, medical coders play a crucial role in ensuring that healthcare providers receive appropriate payment for the services rendered and that patient data is accurately captured and reported.

Managing patient appointments and verifying insurance claims are important administrative tasks within a healthcare setting but are not the primary responsibilities of a medical coder. Providing medical treatment falls outside the scope of a coder’s duties, as this role is focused on the administrative aspect of healthcare, rather than direct patient care.
