On arrival in Denver just prior to extending the gear we encountered turbulence that I would best describe as moderate wake. The conditions were mostly clear. We were in the clear with a smooth ride before and after two bumps in rapid succession. There were no adverse reports on the ATIS. We soon after got a call from the cabin that one of the flight attendants had hit and cut her head. I continued flying and took over ATC while the First Officer coordinated to have paramedics meet the flight. We continued with an uneventful landing. The Flight Attendant was transported to have the cut treated.Later while discussing the event I had mistakenly recalled that injury was part of the [company] definition of severe turbulence. At that busy time and as the aircraft was scheduled to depart I made the decision out of abundance of caution and a mistaken recollection to write the aircraft up. However after later reviewing the manual I discovered my mistake and the encounter was in fact moderate. ATC was not notified because: first; neither one of us felt it to be anything more than moderate and a wake encounter (the severe write up only coming from a mistaken recollection and out of an abundance of caution); and second the time element with added duties of coordinating paramedics and configuring with the encounter taking place just outside the marker.
A319 Captain reported a wake vortex encounter on arrival into DEN that resulted in a Flight Attendant injury.
