If I'm not totally wrong, this process (regarding protons) was first described by U. Fano in 1954 (Radiation Biology, Vol. I, 1. Ed. Hollaender A.) and 1963 (Ann.Rev.Nucl.Sci. 13,1), the best practical explaination I've seen so far is by H. Jung, K. G. Zimmer, 1966 (Current topics of rad. research, Vol II, p. 71-125), but I'm not sure how Geant4 implements it. The total kinetic energy of the incident and of the struck atom must be conserved.

I'm not G4 developer, but I think here the G4HadronElastic model is used (source/processes/hadronic/models/coherent_elastic/src/G4HadronElastic.cc) with G4ChipsProtonElasticXS cross-section (from source/processes/hadronic/cross_sections/src/G4ChipsProtonElasticXS.cc if you are using 10.2).
