Although not an employee of the companies, I have carried out the Independent Review of one facility under CIA and worked with another group who was under CIA. In working with these establishments, I found one to be quite compliant, anxious for feedback and willing to adopt new practices to improve their processes.
The other group was not interested in real solutions. What they wanted was to pay someone to come in, suggest improvements, make efforts at educating the staff; however, this entity was not willing to maintain any gains made by me or my colleagues.
This certainly does not characterize all of them, I'm sure. What I've expressed are my observations only.
What I'd recommend to a coder in a situation with providers under CIA, maintain personal liability insurance. Be sure you're communicating with key folks, like the Compliance Officer and practice leadership. Also, the coder should seek out education on CIAs, make efforts at maintaining continuing education and really pursuing professional growth from this unique opportunity. If you work on any auditing or monitoring for your employer, that would be something to highlight later along on your Resume.
Good luck to you and hopefully this will inspire you to develop your employer's compliance plan and also expand your skill level.
