| Stage 3 – full thickness skin loss involving damage or necrosis of subcutaneous tissue | Muscle necrosis |
| Stage 4 – necrosis of soft tissues through to underlying muscle, tendon or bone | Bone necrosis |
| Unstageable – obscured, full thickness skin and tissue loss, depth unknown | Unstageable |
| Cannot be determined | Cannot be determined |
