Provider number question

i understand that rns and lpns can obtain a medicare provider # at the cms web site (cms.gov) > medicare supplier-provider enrollment.

sincere there is a medicare provider #, is there a medicaid provider #?

if so, is the medicaid provider # specific to each state?

can rns or lpns obtain a medicaid provider #?

if so, where do you obtain the medicaid provider # (e.g., web site, etc.)?

thanks for your help in-advance.
