Narrative:

Near miss with a C150 operating out of abc airport. On board the C150 was a student pilot and an instructor complete last flight prior to solo. Left the XXX hospital on a lifeguard mission back to YYY hospital. I was monitoring frequency as a result of the WWW airport that is very close to the hospital. Operations were normal, checked in with approach, who asked me to report abeam abc airport. At no time did approach provide any traffic information. At approximately 5 NM from abc airport after talking with ZZZ approach during initial call, I was preparing to call transition through the traffic area of an uncontrolled airport. Shortly thereafter, I saw a C150 pass below and to the left of my helicopter. When I idented the airport I saw no airborne traffic and heard 2 xmissions on the local frequency for abc airport.
