EH90.5

ICD-11 MMS 2026-01

Pressure ulceration, ungradable

Description

Pressure ulcer with full thickness skin loss in which actual depth of the ulcer is completely obscured by slough (yellow, tan, grey, green or brown) and/or eschar (tan, brown or black) in the wound bed. Until enough slough and/or eschar are removed to expose the base of the wound, it is not possible to determine whether the ulcer is grade 3 or grade 4.
