Inspired by the experimental anomalies in neutrino physics and recentoscillation data from short baseline and another neutrino experiment, therealization of one extra neutrino flavor seem to be favoring. This extra flavormay change the observable, $|m_{\beta\beta}|$ of currently data taking andnext-generation $(\beta\beta)_{0\nu}$-decay experiments aim to probe andpossibly look the Inverted Ordering region($|m_{\beta\beta}| \simeq 10^{-2}$eV)of parameter space. This observation would allow establishing physics beyondthe standard model and phenomena like lepton number violation and Majorananature of neutrino. The range of this observable ($|m_{\beta\beta}|$) is notvery well defined for both the ordering of mass spectrum(Normal Ordering andInverted Ordering). Several attempts have been made for defining exactly therange for three active neutrino states. For contrasting this range, I haveworked with an extra mass states, $\nu_{4}$ and its effect on the observablewith various combination of CP violation Majorana phases by taking into accountthe updated data on the neutrino oscillation parameters for IO case. Based onthe Monte Carlo technique, a parameter region is obtained using the fourthMajorana-Dirac phase of sterile parameters that lead to an effective mass below0.01 eV or .05 eV for inverted mass ordering case which is planned to beobserved in the near future experiment.
