Late night departure. Last minute (w/in 3-hour of departure time) trip pick-up after 3 weeks off work. Received planned DG (dangerous goods) message via ACARS on preflight. Discussed w/FO (First Officer). Planned DG message had all information I believe we needed (category; placement; type; quantity; etc.) very detailed. Briefed DG as part of pre-departure briefing. Thought that was all we needed since it was so detailed. While pushing back received final DG message on ACARS. FO made comment he wasn't sure if we needed this message prior to push. Too late now (as we had already pushed). Discussed we would look it up in [the] FOM once in a low-threat environment (airborne). Once at cruise referenced company FOM section X.XX.X which states company policy is more restrictive than FAR and we are not to push until final DG summary is received.
