The off-diagonal hyperfine interaction between the 6p{sub 1/2} and 6p{sub 3/2} states in {sup 133}Cs is evaluated in third-order MBPT giving 37.3 and 48.3 Hz, respectively, for second-order energies of the 6p{sub 3/2} F=3 and F=4 levels. This result is a factor of 10 smaller than one obtained from an uncorrelated first-order Dirac-Hartree-Fock calculation and used in the analysis of a recent high-precision ({<=}2 kHz) measurement of the 6p{sub 3/2} hyperfine structure [Gerginov et al. Phys. Rev. Lett. 91, 72301 (2003)]. The factor of 10 difference has negligible effect on the conclusions of the recent experiment but will become important for experiments carried out at a precision of better than 1 kHz.
