In this work, we study Lie symmetry analysis for integrable equation of combining the modified Calogero–Bogoyavlenskii–Schiff equation with its negative order (MCBS–nMCBS) that is one of the applications of symmetries. Symmetry analysis and similarity reduction of the (\(2+1\))-dimensional combined MCBS–nMCBS equation are investigated by using the invariance of the equations under the Lie group of transformations. We have found Lie point symmetries of this equation and then we reduced combined MCBS–nMCBS equation to ordinary differential equation through two successive reductions. The same integrable equation was constructed and solved by Wazwaz (Nonlinear Dyn 91:877–883, 2018) using the tanh/coth method. However, we find out the complex and singular solutions using Lie group of transformation method. Some of the derived solutions are analyzed graphically. Eventually, we also obtained conservation laws of the equation with corresponding Lie symmetry.
