We consider the next-to-leading order corrections to the NN scattering amplitude in modified Weinberg approach. We present the corrections to the partial wave phase shifts. To probe the convergence, for the 1S0 partial wave by applying the subtractive renormalization we compare the results of perturbative and non-perturbative treatment of the next-to-leading order contact interaction correction to the effective potential.
