Definitely, Sarah, you benefit from taking additional courses in billing/coding, because you’ll standout than rest of the other Medical Assistants. In addition, you’ll be competent in the both technical field as well as business side of the healthcare. As your future takes you; perhaps, you can be both MA and either medical biller or coder, mostly in the physician office. I would say you’ve taken a step further in your career by taking an additional challenge.
Hope this helps.
