i'm in nm:
cpms (called lm's here) are licensed and regulated through the dep't of health. there is a defined scope of practice and designated protocols that are followed within that scope. transfers of hb's are readily accepted and are generally met by kind and understanding hospital staff in 2 of the 3 hospitals here in albuquerque. overall, our state is exceedingly friendly to cpms and cpms generally interact with the medical community pretty well. there are some snags here and there, but it is to be expected when 2 different models of care come together and both are very different, though the end goal is the same.
cnms are licensed and can practice individually (then no hospital privledges. ie, in the case of a hospital transfer, the cnm cannot deliver the baby, and becomes an advocate for mom/baby, but has no say in final decision making), or work in the hospital (full privledges under their scope of practice). a hb cnm, under state law, can write her own protocols under the scope of practice. i am not positive, but i believe cnms are regulated under something other than the health dep't.
overall, i think my state is quite friendly towards midwives of both licensures, and medicaid covers homebirth with either type of mw.
