A medical billing and coding specialist puts the appropriate diagnostic codes on medical billing claims forms to ensure that the hospital, care facility or doctor's office is reimbursed by insurance companies. He or she learns the classification system used for medical coding and analyzes medical documentation to review the medical procedures, diseases and injuries dealt with at the facility. Medical billing and coding specialists are also responsible for following special protocols for each claim. If you want to become a medical billing and coding specialist, then you'll need training in the field, possibly an industry certification and a high school diploma or college degree.

A high school diploma or its equivalent is the basic educational requirement to become a medical billing and coding specialist. Those who want to advance in the field usually consider at least an associate's degree related to coding, and many employers require the degree for employment. Common classes focus on productivity software, law, anatomy, biology, insurance, coding and medical records. Many programs include an externship at a medical facility as a final requirement. There also are certificate programs available that can be completed in less time, and some employers even train coders on the job. In any case, coding classes can help prepare you for the job and help you perform better during your employer's training program.

To become a medical billing and coding specialist, you can also consider taking one of the many certification exams available. The exams typically expect that you have some experience in the field, but not all of the testing vendors require this. The tests usually show you example medical records and ask you to code them according to the appropriate standards. The tests allow you to bring codebooks but issue a time limit for each of the test's parts. Many of the tests recommend that you have done college coursework in medical coding and require a high school diploma at a minimum.

Some employers prefer that you have experience in a healthcare setting before you become a medical billing and coding specialist with their company. Participating in a college degree program or certification program that required you to work in an office setting will be helpful when you apply for a permanent job. Employers also like to see that you understand insurance plans, have strong analytical skills and understand medical terminology and anatomy. Communication skills are also vital, because you'll be working with others in the office.
