We report measurements of the exclusive cross section for e(+)e(-)->(DD*-)-D-0 pi(+) as a function of center-of-mass energy from the (DD*-)-D-0 pi(+) threshold to 5.2 GeV with initial-state radiation. No evidence is found for Y(4260)->(DD*-)-D-0 pi(+) decays. The analysis is based on a data sample collected with the Belle detector at or near a center-of-mass energy of 10.58 GeV with an integrated luminosity of 695 fb(-1) at the KEKB asymmetric-energy e(+)e(-) collider.
