The procedure of successive approximations beyond the quasichemical one for lattice gas systems of arbitrary density is suggested. Even at the lowest order approximation the calculation results for the phase diagram of the system of particles with attractive nearest neighbor interaction are in good agreement with Monte Carlo simulation.
