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
