The total cross section of [ital NN][r arrow][ital d][pi] very near threshold is calculated in a simple distorted wave impulse approximation including one-body, pion rescattering, and sigma and omega meson exchange current (MEC) contributions. Calculations with MEC are in good agreement with recent TRIUMF measurements while calculations without MEC are significantly smaller. Thus the MEC mechanism, which was proposed to explain a large enhancement in the [ital pp][r arrow][ital pp][pi][sup 0] cross section, is consistent with [ital NN][r arrow][ital d][pi] data.
