Both are responsible for encoding a patient visit accurately, coders for medical records and for the medical billing department; medical billers for the insurance claims for reimbursement. Together, these two jobs use the ICD-10CM and CPT-4 coding systems to help facilitate payment between health care providers, insurance companies, and patients, and transcribe accurate medical records for each patient visit.
There are many things medical billers and coders do at work each day, this is an overview of the duties of each position.
Medical coders transcribe a patient visit and physician's treatment into a series of universal codes (ICD-10, CPT-4, HCPCS). These codes are used by medical facilities and insurance companies to create a record of a patient's visit and submit an insurance claim. Each code has guidelines on how they can be used, so accuracy is essential.
Medical billers take the coded report of a patient visit from a medical coder and submit claims to the insurance company. They follow up with the insurance company and the patients to make sure the medical office is compensated properly.
