We review the differences in Higgs phenomenology that arise in the NMSSM compared to the MSSM with the emphasis on Higgs decay modes. The focus will be on the decay mode of the standard model like Higgs boson, h -> a a, and related decay modes of the heavy CP even Higgs boson, H -> Z a, and the charged Higgs boson, H^+ -> W^+ a. We summarize current experimental constraints and prospects for the LHC.
