We point out how, in certain models of New Physics, the same combination of couplings occurs in the amplitudes for both D{sup 0}-{bar D}{sup 0} mixing and the rare decays D{sup 0} {yields} {ell}{sup +}{ell}{sup -}. If the New Physics dominates and is responsible for the observed mixing, then a very simple correlation exists between the magnitudes of each; in fact the rates for the decay D{sup 0} {yields} {ell}{sup +}{ell}{sup -} are completely fixed by the mixing. Observation of D{sup 0} {yields} {ell}{sup +}{ell}{sup -} in excess of the Standard Model prediction could identify New Physics contributions to D{sup 0}-{bar D}{sup 0} mixing.
