Narrative:
I was called out on an emergency medical transport from XXX with a return to a local hospital in YYY. We elected to remain clear of the class B airspace, so started each climb as we cleared the next class B ring. We observed the arriving traffic on runway 13, so changed our course to the north to avoid the inbound traffic. We did not observe any traffic that was close. Upon our arrival back to XXX, we were instructed to contact approach control. When I talked to them, I was told there was a possible class B incursion which caused a TCASII alert. The aircraft with the TCASII alert then climbed into another aircraft. Due to the low surface visibility, it is possible that we began our last climb early. We thought we were beyond the 4000 ft ring. We were monitoring approach control, on the VFR frequency, as we usually do, and were squawking our discreet transponder code. We were not up on the inbound traffic approach frequency, so heard no traffic calls to us. In the future, we will always try to talk to approach control. The IFR arriving controller should also coordinate with the VFR controller if there is a conflict. This may have prevented us from causing a TCASII alert.

Title: AN EMS ATX ACFT ENTERS THE CLASS B WHILE FLYING IN MARGINAL VFR WX ON A NO FLT PLAN TYPE OP.
Narrative: I WAS CALLED OUT ON AN EMER MEDICAL TRANSPORT FROM XXX WITH A RETURN TO A LCL HOSPITAL IN YYY. WE ELECTED TO REMAIN CLR OF THE CLASS B AIRSPACE, SO STARTED EACH CLB AS WE CLRED THE NEXT CLASS B RING. WE OBSERVED THE ARRIVING TFC ON RWY 13, SO CHANGED OUR COURSE TO THE N TO AVOID THE INBOUND TFC. WE DID NOT OBSERVE ANY TFC THAT WAS CLOSE. UPON OUR ARR BACK TO XXX, WE WERE INSTRUCTED TO CONTACT APCH CTL. WHEN I TALKED TO THEM, I WAS TOLD THERE WAS A POSSIBLE CLASS B INCURSION WHICH CAUSED A TCASII ALERT. THE ACFT WITH THE TCASII ALERT THEN CLBED INTO ANOTHER ACFT. DUE TO THE LOW SURFACE VISIBILITY, IT IS POSSIBLE THAT WE BEGAN OUR LAST CLB EARLY. WE THOUGHT WE WERE BEYOND THE 4000 FT RING. WE WERE MONITORING APCH CTL, ON THE VFR FREQ, AS WE USUALLY DO, AND WERE SQUAWKING OUR DISCREET XPONDER CODE. WE WERE NOT UP ON THE INBOUND TFC APCH FREQ, SO HEARD NO TFC CALLS TO US. IN THE FUTURE, WE WILL ALWAYS TRY TO TALK TO APCH CTL. THE IFR ARRIVING CTLR SHOULD ALSO COORDINATE WITH THE VFR CTLR IF THERE IS A CONFLICT. THIS MAY HAVE PREVENTED US FROM CAUSING A TCASII ALERT.
