        Only if your area has already adopted the 2017.

          Well seems to me that hospital grade MC is NOT allowed for EM circuits.

          (3) Mechanical Protection of the Emergency System.
          The wiring of the emergency system in hospitals shall be
          mechanically protected. Where installed as branch circuits
          in patient care areas, the installation shall comply with the
          requirements of 517.13(A) and (B). The following wiring
          methods shall be permitted:
          (1) Nonflexible metal raceways, Type MI cable, or Schedule
          80 PVC conduit. Nonmetallic raceways shall not be
          used for branch circuits that supply patient care areas.
          (2) Where encased in not less than 50 mm (2 in.) of concrete,
          Schedule 40 PVC conduit, flexible nonmetallic
          or jacketed metallic raceways, or jacketed metallic
          cable assemblies listed for installation in concrete.
          Nonmetallic raceways shall not be used for branch circuits
          that supply patient care areas.
          (3) Listed flexible metal raceways and listed metal
          sheathed cable assemblies in any of the following:
          a. Where used in listed prefabricated medical headwalls
          b. In listed office furnishings
          c. Where fished into existing walls or ceilings, not otherwise
          accessible and not subject to physical damage
          d. Where necessary
