The present knowledge of Lamb shift, fine- and hyperfine structure of the $mathrm{2S}$ and $mathrm{2P}$ states in muonic deuterium is reviewed in anticipation of the results of a first measurement of several $mathrm{2S-2P}$ transition frequencies in muonic deuterium ($mumathrm{d}$). A term-by-term comparison of all available sources reveals reliable values and uncertainties of the QED and nuclear structure-dependent contributions to the Lamb shift, which are essential for a determination of the deuteron rms charge radius from $mumathrm{d}$. Apparent discrepancies between different sources are resolved, in particular for the difficult two-photon exchange contributions. Problematic single-sourced terms are identified which require independent recalculation.
