In the minimal supersymmetric model (MSSM), the {ital tree}{minus}{ital level} mass of the lightest Higgs scalar {ital h}{sup 0} cannot be larger than the mass of the {ital Z} boson. We have computed the one-loop radiative correction to the upper bound on {ital m}{sub {ital h}}{sup 0} as a function of the free parameters of the MSSM. We find that the dominant correction to {ital m}{sub {ital h}}{sup 0}{minus}{ital m}{sub {ital Z}} is large and positive and grows like {ital m}{sub {ital t}}{sup 4}, where {ital m}{sub {ital t}} is the top-quark mass. As a result, the MSSM cannot be ruled out if the CERN {ital e}{sup +}{ital e{minus}} collider LEP-200 fails to discover the Higgs boson.
