During the preflight after the First Officer finished the walk around he said the deicing was finished. I asked if the aircraft was clean and free of ice and he said yes. Approximately 40 minutes later when push back was imminent the flight deck filled with smoke. After shutting off packs; fans; opening windows; and running checklists the smoke dissipated.  There was no smoke in the cabin. We confirmed the source was from the deicing process. The aircraft was not configured for deicing. I spoke with the deicing team over the radio and they said they the deicing crew plugged in their headset in and spoke to us over the aircraft's interphone however no one had spoken to us. Later I found out that the deice team spoke with the First Officer during his walk around asking him if the airplane was configured for deicing which he said it was. The First Officer did not relay the information to me and assumed the deicing was complete. Also I found out that the deicing process was stopped due to a catering truck servicing the aircraft and then resumed after catering was finished. There was miscommunication and an assumption that the deicing was complete when it wasn't. No one notified me; the Captain; that the deicing team was deicing. We debriefed the situation with an emphasis on relaying all information and not assuming the deicing was complete.
B-737 Captain reported a fume event prior to gate pushback due to a communications breakdown between Captain; First Officer; and deicing crew.
