Is it legal to alter RN documentation?

I recently started in HH. To make a long story short: I discharged a patient for non-compliance and the pt stated she did not want further services, and her house is not very safe, ie: used needles everywhere after I gave sharps container to her, anyway, I documentated everything and filled out a discharge OASIS and gave it the office manager. About the time that person was getting around to putting in the computer, a business development coordinator decided to override my decision and not put the OASIS in. In fact, that person went to see her after I had 3 other nurses in with me to verify the noncompliance, and told put her back on service when she said she did not want it. I made phone calls to the doctor and reported it, but she has the right to refuse, right? My nursing documentation got shredded. Is this even legal? To top it off, I did not find out about this until after it had been done. When I confronted them and asked if it was legal, I was told that they know what is legal and what is not. I am convinced this issue is about money. They also tell me to round up on the pain scale, and to document things like incontinence if they pee when they sneeze. I know that is stress incont, and needs to be documented differently. I am not sure what to do.
