Narrative:

I was about 4 mi northwest of ZZZ hospital at 2000 ft MSL. I had finished engaging the autoplt when my crew member shouted 'aircraft 9 O'clock position, low!' I looked down to see a white cessna 172 or 152, with a red stripe, pass at 75-100 ft below me. He continued on the same heading and altitude until he was 1 1/2 to 2 mi from me. He then flew a parallel course to me for about a mi and then turned east.
