insurance

I am a Self Employed healthcare provider and I just opened my business last year, so this is new for me. The majority of my income has been from insurance (Anthem/BCBS, United healthcare/UMR/Surest, aetna, wellcare, etc).  What documents will I need to file taxes to report this income? Will the insurance company send me a statement? How does that work? I want to be prepared and need to know how to navigate reporting income received by insurance for providing healthcare services.
