We investigate the dimuon Higgs decay h → μ+μ- in the context of an extended Scotogenic model. The model introduces a singlet complex scalar in addition to the standard Scotogenic scalar doublet and singlet fermions, charged under a dark ℤ2 symmetry. By exploring the one-loop contributions, we show that the model allows for sizable deviations in the Higgs dimuon decay rate, quantified by the quotient Rμμ = Br(h → μ+μ-)/Br(h → μ+μ-)SM. Crucially, these deviations comply with experimental limits, including those on Br(μ+ → e+γ) and Br(h → γγ). Such deviations can be tested and constrained by future precision measurements at the LHC.
