Higher-order cusp relations for the electron density are derived for high-excited atoms, ions and molecules. The spherical average of the wavefunction is zero at a nucleus. The cusp conditions apply rigorously even in the cases with 1>0 orbital density contributions. Thus, the location of the nuclei as well as their identify can be ascertained from the excited state density just like in the ground state.
