The EPUAP/NPIAP/PPPIA (2019) has added two new categories to describe previously upgradeable pressure ulcers.
Unstageable
Full-thickness loss in which actual depth is completely obscured by slough and/or eschar in the wound bed. Until enough slough and/or eschar is removed to expose the base of the wound, the true depth and therefore stage cannot be determined, but it will be either a Category 3 or 4.
