So I may not be understanding exactly what you're getting at - are you going to be direct billing Medicare/aid or are you working with a group and you're a contracted employee but using their coders, nurses, supplies, etc?
If you're an employee then getting paid $22 for a $72 code makes sense. Your employer can anticipate actually getting $50 on average for the code, and your employer needs to cover their overhead (nurses, equipment, facility, power, etc). Unless you're already looking at the work RVU, in which case I'm not sure how you found out what Medicare/aid pays for that, I've never been able to unlock the mysteries of that box. Even then you need to consider what CMS says they reimburse and what they actually reimburse are vastly different.
Now keep in mind, lets say you bill a 99214. The wRVU is 1.44, so you'll actually make $42 for seeing that patient because it's worth more than 1 RVU to you.
As aPD mentioned, you're not residency trained. I recommend getting your foot in the door, and even if you're grossly underpaid stick it out for a little experience and work hard as hell so you can then leverage your new found experience and reputation into more $$$. When you apply for a new job, if you can say "My RVUs were at the national 98th percentile for this last job I was at" you will 100% be able to leverage that into more money (trust me, this is personal experience).
