Narrative:

I departed hospital for a scenic flight west of ZZZ on highway approximately as I approached the scene, approach notified me that small transport Y was approaching at my 3 O'clock position at 1400'. My third rider sitting in the rear of the aircraft said he had visibility contact with the helicopter and it was approaching from the right rear. I was at 2000' descending and notified that I had the landing area in sight and was landing. I contacted highway patrol and he instructed me to land east of his unit. As I started my approach small transport Y moved to the left side of my helicopter and remained outside of my approach path with his gear up. I felt he was observing the scene and did not intend to land. Visibility contact with him was lost as I turned to final. There was no radio contact at any time with small transport Y. As I turned short final, landing to the southeast, small transport Y approached from my left landing to the ssw, directly in front of me. At that time I felt we were too close and aborted my landing turning to the north to preclude a midair. I contacted hospital and returned to home base hospital. Callback conversation with reporter revealed the following: reporter stated second helicopter was faster than his. Was spotted behind and to the right. As helicopter I made proper pattern from the area, helicopter 2 passed behind, to the left and landed at helicopter 1's intended T/D spot. Flight nurse said, 'he's going to hit us.' at the same time pilot 1 broke off landing and left the area. These are competitive EMS services. Reporter knows other pilot was aware of his presence as both were called as traffic to the other by approach and both acknowledged. Reporter would have aborted sooner but second helicopter had gear retracted and did not appear to be landing. Reporter sent report to FAA and created quite a stir. Positive result was meeting of all helicopter pilots in area, EMS ambulance and others, resulting in specific policies and procedures.
