An HCC coder, or hierarchical condition category coder, is someone who transcribes a patient’s medical history into a database using standardized codes. This includes diagnosis and treatment and is typically later used for insurance and medical billing purposes. As an HCC coder, you may go over a patient’s records to ensure accuracy and audit records and documentation to ensure the entering of codes was correct. You typically work in a hospital or other health care setting. There are several different jobs that fall into the HCC coder category, such as specialist, manager, trainer, auditor, and analyst.
