The buses collided along Guy R. Brewer Boulevard and Mathias Avenue in Jamaica just after 8:45 a.m.
The MTA said a Q112 with no passengers on board struck a Q111 with more than a dozen passengers on board.
As many as 16 people, mostly passengers on the bus that was struck, were taken to Jamaica Medical Center.
None of the injuries were considered life threatening.
It is believed icy conditions contributed to the crash, which is under investigation.
