During pushback a Flight Attendant called and informed me that a passenger was refusing to wear their face mask.  I asked if she wished to have the passenger removed for non-compliance to which she responded in the affirmative.  I had the push crew pull us backed to the gate and requested a Supervisor from operations.  Arriving at the gate; the Flight Attendant informed me that she made four attempts to have the customer replace his mask over his nose to which he refused or was otherwise non-compliant.  The Gate Agent boarded the plane and was unable to get the customer to wear the mask appropriately so he was removed.
Air Carrier Captain reported a passenger would not comply with face mask policy and was removed from the flight.
