How much does a medical billing and coder make?

This will range depending on your experience and the nature of work you are doing. A medical coder can make upwards of $40,000 working from home as an independent contractor after a few years of experience, while coders running their own coding firm can earn over $100,000 a year. There are many cases of these happening.

Not too much. It is a hard work. Advertisers just make it look cool,but I don't think that it is. Medical coding personnel in a doctor's office without credentials earn about $12-$15 an hour. If you are credentialed then it's about $18-$20 an hour. In a hospital, coding personnel earn about $20+ per hour.

The Government Occupational Outlook handbook suggests that the industry of healthcare is still going to grow for the next decade so expect some improvement with the salary as well.
