lilraysofhope - like your AD name says - have a small ray of hope! Yes I know hearing disability sucks and it greatly hinders us. I know that lot of "cool jobs" involve lot of communicating but it's
so so so important that you do not let it hinder you from stepping up - very important!!
I was just hired yesterday as a web master for university with a nice salary and benefit (I start in 2 weeks). This job does involve a lot of communicating and meetings. How the hell did I get this job? Well - it's very important that you exhibit a strong confidence in your ability and especially in yourself to perform the job and yes they know & understand that I have a hearing disability. They're very willing to provide me with some accommodations because after all... every employer pays for result and if you can deliver the result beyond their satisfactions - they are pretty damn eager to pay for your accommodation. Most jobs don't want to pay extra for you. why? because they feel it's not worth the cost if you're just a regular type and that is understandable. That is why it's important to make yourself very skillful.
I strongly refused to limit myself to "drone job" with a very limited amount of communication with people. I did spend some years as a drone job when I was young and it SUCKS! That's why I spent years learning and getting work experience. Since you are going back to school, if I may... I would suggest you to learn a skill that is highly-sought after or the one where you can promotion with salary increase over time such as programming, high-level data entry (designing database), etc. etc. Do not limit yourself to "drone job." If you still want to do medical coding, you should be the type where you can design the database or program to make it efficient. That is quite a lucrative job! and more exciting too!
But that's just my opinion and my personality

I'm pretty sure you'd love a comfortable job and communicating with a colleague. If you rather be alone and do some work... ignore what I just said. meanwhile - good luck to your career prospect and work hard at it!
Right now - economy is CRAP and and will continue to be CRAP for probably next couple years. Don't feel too bad. You will catch a lucky break.
