A precision measurement of the D-0 meson mass has been made using similar to 281 pb(-1) of e(+)e(-) annihilation data taken with the CLEO-c detector at the psi(3770) resonance. The exclusive decay D-0 -> K-S phi has been used to obtain M(D-0)=1864.847 +/- 0.150(stat)+/- 0.095(syst) MeV. This corresponds to M((DD*0)-D-0)=3871.81 +/- 0.36 MeV, and leads to a well-constrained determination of the binding energy of the proposed (DD*0)-D-0 molecule X(3872), as E-b=0.6 +/- 0.6 MeV.
