What is Medical Billing and Coding?
Medical coders and billers help support healthcare offices by transcribing patient visits into alphanumerical codes, which are understood universally by insurance companies and healthcare organizations. These are used to create insurance reimbursement claims and update medical records. Accuracy and attention to detail is very important in medical coding and medical billing — medical insurance companies (payers) can reject a reimbursement claim if errors are detected.
Medical coders and medical billers are two distinct roles, but they can be done by the same person in many cases.
Medical coders transcribe the details of a patient appointment into a set of standard alphanumeric codes that all healthcare organizations, government agencies, and insurance companies understand. The diagnosis, treatment, prescriptions, procedures, medical equipment, and other medical supplies all have corresponding codes. These codes are used by the medical facilities and insurance providers to update health records and submit insurance claims. The codes must be used accurately to prevent delays in reimbursement to the medical office or healthcare provider.
Medical billers take the information provided by the medical coder or the provider directly and prepare and submit insurance claims to the medical insurance entities. The medical biller will also “scrub” the claim for errors, making sure the format is ideal for each insurance company’s internal standards. They also follow up with the insurance companies to make sure the reimbursement claim is processed and paid promptly. They may also send letters or notifications to the patient for their remaining portion of the bill.
Why Become a Medical Coder and Biller?
Medical billing and coding is a skilled job that is direly needed by every medical office, hospital, clinic, and healthcare facility. These professionals are an integral part of the revenue cycle which keeps medical offices running.
The pay is robust, and earning additional specialty certifications may also help you earn more, according to the American Association of Professional Coders (AAPC). [2]
Many medical billers and coders now work remotely, with several of these jobs being transferred to remote work in the early 2020s. This gives you more time to focus on your work-life balance and spending less time commuting. Those coders and billers that still work in an office rarely interact with patients, so this job is great for people who are self-starters, who can manage their own time, and are more analytical.
