The search for MSSM Higgs bosons will be an important goal at the LHC. Inorder to analyze the search reach of the CMS experiment for the heavy neutralMSSM Higgs bosons, we combine the latest results for the CMS experimentalsensitivities based on full simulation studies with state-of-the-arttheoretical predictions of MSSM Higgs-boson properties. The experimentalanalyses are done assuming an integrated luminosity of 30 or 60 fb^-1. Theresults are interpreted as 5$ \si$ discovery contours in MSSM M_A-tan_betabenchmark scenarios. Special emphasis is put on the variation of the Higgsmixing parameter mu. While the variation of mu can shift the prospectivediscovery reach (and correspondingly the ``LHC wedge'' region) by about Deltatan_beta= 10, the discovery reach is rather stable with respect to the impactof other supersymmetric parameters. Within the discovery region we analyze theaccuracy with which the masses of the heavy neutral Higgs bosons can bedetermined. An accuracy of 1-4% should be achievable, depending on M_A andtan_beta.
