CMS K913 box refers to the following codes, see description below. But I can not find these in NFPA 99, 2018. Has the numbering been changed?
Electrical Systems – Wet Procedure Locations
Operating rooms are considered wet procedure locations,
unless otherwise determined by a risk assessment conducted
by the facility governing body. Operating rooms defined as wet
locations are protected by either isolated power or ground-fault
circuit interrupters. A written record of the risk assessment is
maintained and available for inspection.
