### Description

Since the discovery of a Higgs-like particle at the LHC considerable effort has been undertaken to reveal its nature and properties. To make significant comparisons of the experimental measurements and theory predictions, high-precision calculations are necessary.
One of the particle's basic properties is its mass; due to the very precise measurement, the current MSSM prediction is challenged.

I will present the most recent status of the Higgs-particle spectrum in the CP-violating MSSM in the Feynman-diagrammatic approach with non-trivial renormalization. The known two-loop contributions (leading terms of $\mathcal{O}{(\alpha_t\alpha_s+\alpha_t^2)}$) are briefly reviewed and new results and implications of the full subleading QCD terms of $\mathcal{O}{(\alpha_{\mathrm{any}}\alpha_s)}$ are shown.
