Narrative:

The north satellite airspace light was on-had to protect the airspace. Departed aircraft X off runway 9R; was a westbound normal operations would be on a 320 heading after protecting for a missed approach off 9L; since the north satellite light was on; after protecting for the missed approach I turned aircraft X to a 040 heading (that is as far left as I can turn while protecting the airspace). Then I departed aircraft Y runway heading; aircraft Y was also a westbound; but a jet. During the time aircraft Y was off the departure end climbing; the north satellite light went out; and the north tower called in my ear to tell me that 'aircraft a went on his own' I was unsure what they were talking about and said say again at least once; then the controller said 'the guy on tango.' it took me a minute to realize they were speaking of an aircraft on taxiway tango reference my 9R arrival; there was an aircraft in the ocs (obstacle clearance surface) and my arrival need to be sent around. I sent aircraft Z around; had to climb to 4000 and fly heading 090. I then turned aircraft Y to a 320 heading that is the standard heading for westbound on east flow; and then turned the missed approach in trail of aircraft Y. Approach control called to question if I turned aircraft Y to a 320 I said yes; not sure but it looked like they turned the propeller after the light went out so they were worried that aircraft Y was going to be in conflict with him. I had a lot going on in those seconds that I don't know if separation was lost.the north tower needs to state exactly what they mean; I have traffic in the ocs (obstacle clearance surface) send your arrival around. And the TRACON should coordinate with the tower if they are going to turn a propeller off the assigned heading. We are required to not give the TRACON a jet on the same heading as a propeller until the propeller is at least 8 miles from the airport; I gave the TRACON the propeller on a 040 heading; there was no coordination done to tell me that propeller had been turned from that heading.

Title: ORD Tower Controller reports of miscommunication between him and another Tower Controller that lead to confusion and a go around. Other controller wasn't specific in what was going on which lead the reporter to give the TRACON an unsafe situation.
