Entry-level coding jobs can cover positions in the health care industry with medical coding or those in programming and software development. Your responsibilities in each of these careers are very different. As a medical coder, you correspond with health care providers, insurance companies, and patients. You use the information you gather to review health charts and records and assign a diagnosis and treatment code. This is primarily for billing purposes. As an entry-level coder in the computer industry, your duties include conducting trial runs on new software, translating program performance into actionable improvements, and collaborating on code and program development with other coders to create the end-product.
