The most important references are:
A. Dal Corso and A. Mosca Conte,
Spin-orbit coupling with ultrasoft pseudopotentials: application to Au and Pt,
Phys. Rev. B 71, 115106 (2005)
A. Dal Corso,
Projector augmented-wave method with spin-orbit coupling: applications to simple solids and zincblende-type semiconductors,
Phys. Rev. B 86, 085135 (2012)
and references therein. I think it is neither exact nor “pertubational”. Its main approximations are related to the “pseudization” of the atomic wave functions, as in the scalar relativistic case, plus the neglect of the “small component” in the Dirac equation, plus other details that I don’t know exactly.
Hope this helps,
