If you have experience reviewing coding errors, you may qualify to have your -A removed, which is a big step.
That being said, my personal opinion is that newbie coders will do best in an environment where they regularly interact and can be mentored by more experienced coders. While it is certainly possible for that to be remote, it is not the workflow for many remote companies.
Even though I was not mentored by coders, my onsite interactions with MDs, RNs, PAs, NPs, other billers, etc. earlier in my career surely lead me to the knowledge I have today. There is no way I would have gained the same knowledge in the same timeframe in a remote environment.
There are literally hundreds of posts here from CPC-As asking why no one will hire them, even if not remote. I've probably personally replied to this same type of question at least a dozen times.
Almost all experienced coders and hiring managers recommend the same basic things to new CPC-As. 1) Get your foot in the door with any position at a company that employs coders. Don't only consider a coding position. 2) Get your -A removed by working as a biller, authorization specialist, etc. (which I think you already have) 3) Network at your employer and outside your employer. Make buddies with the coding department if possible. 4) Make sure your cover letter and resume are spot on. Have a few customized for the different types of positions you are applying for. 5) Practice your interview skills.
I know if I was looking to hire, I would certainly consider someone within my organization who has already proved themselves in another position above someone from outside.
