How to Become a Medical Biller

A medical biller is responsible for entering in patient information into a database and correlating it with the medical services the patient receives. There are a few things you will need to know in order to become a medical biller. On-the-job training and certifications are required. You can either complete a certification training course or get an associate degree.


There are many entry-level positions for medical billers that only require a high school diploma. Usually, the positions also require basic computer experience, especially experience with databases or data entry. Experience in an office environment, preferably a doctor's office, or in a financial office, such as a bank or insurance office, where records were handled daily, quickly and accurately, is also acceptable to many medical biller employers.

There are just over two hundred programs in the US for Medical Biller or Medical Insurance Specialists and most of these programs are two years. There are also online and distance education options available.


Medical Biller Certification is voluntary and not all employers will require the certification. However, completing certification will introduce you to concepts like medical terminology and fraud detection, which may take several months to complete on the job. Since many medical billers are judged by the accuracy of their claims, and some positions ask for 90% accuracy on original submission of documents. Usually proper training will improve the accuracy of the claim submission.

The American Medical Billing Association (AMBA) offers the Certified Medical Reimbursement Specialist credential. To attain certification, you need to become a member of the AMBA and pass the Certified Medical Reimbursement Specialist test. The minimum score required is 85%. Both the registration and the test can be completed online. The AMBA has study materials and books available for sale on their website to help you complete the test.

Tips and Advice

Try to get experience working with computers, especially on databases or performing data entry. Not all of this experience has to be completed in a medical or insurance office, so any experience working with databases, entering data from forms and submitting information quickly and accurately is an asset.

Accuracy is one of the most desired attributes in a medical biller. Some databases will provide information about user accuracy, or your current supervisor can provide a report of your accuracy. A ninety percent or higher accuracy rate is a number you can include on your cover letter, resume or discuss in your interview for a medical biller position. Take steps to improve your accuracy by learning medical and insurance acronyms and by studying the correct spellings for medical and anatomical terms.

Different Types of Jobs

Most medical billers work in physician's offices, hospitals and insurance companies. Their daily duties are usually quite similar, requiring them to work in medical financial databases, but medical billers who work in physician offices may be asked to perform additional clerical duties such as filing or scheduling appointments.
