Direct searches for lepton flavor violating Higgs boson decays in the $\tau\mu$ channel have been recently reported by the CMS collaboration. The resultsdisplay a slight excess of signal events with a significance of 2.5$\sigma$,which translates into a branching ratio of about $1$%. By interpreting thesefindings as a hint for beyond the standard model physics, we show that theType-III 2HDM is capable of reproducing such signal while at the same timesatisfying vacuum stability, perturbativity, electroweak precision data,measured Higgs standard decay modes and low-energy lepton flavor violatingconstraints. We have found that the allowed signal strength ranges for the$b\bar b$, $WW^*$ and $ZZ^*$ standard channels shrink as soon asBR$(h\to\tau\mu)\sim 1$% is enforced. Thus, we point out that if the excesspersists, improved measurements of these channels may be used to test ourType-III 2HDM scenario.
