The present knowledge of Lamb shift, fine- and hyperfine structure of the 2S and 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 (ddb24f362942ba844f7d5301046aa" title="Click to view the MathML source">μ$\mu$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 ddb24f362942ba844f7d5301046aa" title="Click to view the MathML source">μ$\mu$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.
