We present a search for the flavor-changing neutral current decay B{sub s}{sup 0}{yields}{phi}{mu}{sup +}{mu}{sup -} using about 0.45 fb{sup -1} of data collected in pp collisions at {radical}(s)=1.96 TeV with the D0 detector at the Fermilab Tevatron Collider. We find an upper limit on the branching ratio of this decay normalized to B{sub s}{sup 0}{yields}J/{psi}{phi} of (B(B{sub s}{sup 0}{yields}{phi}{mu}{sup +}{mu}{sup -})/B(B{sub s}{sup 0}{yields}J/{psi}{phi}))<4.4x10{sup -3} at the 95% C.L. Using the central value of the world average branching fraction of B{sub s}{sup 0}{yields}J/{psi}{phi}, the limit corresponds to B(B{sub s}{sup 0}{yields}{phi}{mu}{sup +}{mu}{sup -})<4.1x10{sup -6} at the 95% C.L., the most stringent upper bound to date.
