517.12 Wiring Methods.
Except as modified in this article, wiring methods shall comply with the applicable requirements of Chapters 1 through 4 of this Code.
517.13 Grounding of Receptacles and Fixed Electrical Equipment in Patient Care Areas.
Wiring in patient care areas shall comply with 517.13(A) and (B).
(A) Wiring Methods. All branch circuits serving patient care areas shall be provided with an effective ground-fault current path by installation in a metal raceway system, or a cable having a metallic armor or sheath assembly. The metal raceway system, or metallic cable armor, or sheath assembly shall itself qualify as an equipment grounding conductor in accordance with 250.118.
(B) Insulated Equipment Grounding Conductor. The grounding terminals of all receptacles and all non?current-carrying conductive surfaces of fixed electrical equipment likely to become energized that are subject to personal contact, operating at over 100 volts, shall be connected to an insulated copper equipment grounding conductor. The equipment grounding conductor shall be sized in accordance with Table 250.122 and installed in metal raceways or as a part of listed cables having a metallic armor or sheath assembly with the branch-circuit conductors supplying these receptacles or fixed equipment.
There are exceptions.

I might add to my reply, that, because of those exceptions, the method can vary depending on what equipment is being supplied.
Lighting fixtures more than 7-1/2 ft AFF have a different requirement than receptacles.
