0.000What This Code Means
A stage 2 pressure sore affecting contiguous areas of the back, buttock, and hip, involving partial-thickness skin loss with blister, abrasion, or shallow crater.
Coding Tips
- •Document the extent of involvement across the contiguous sites and describe the appearance of skin loss
- •Contiguous site involvement may indicate more severe pressure exposure; consider increased intervention and monitoring
Clinical Significance
Stage 2 pressure ulcers of the contiguous site of back, buttock, and hip represent partial-thickness skin loss spanning multiple connected anatomical areas. This contiguous involvement indicates broader pressure exposure and a larger wound surface area than single-site ulcers. The multi-site nature complicates treatment planning and pressure redistribution, as relief for one area may worsen another.
Documentation Requirements
- ✓Documentation that the pressure ulcer spans contiguous areas of back, buttock, and hip
- ✓Stage explicitly documented as stage 2
- ✓Total wound dimensions across all involved sites
- ✓Wound appearance at each anatomical area
- ✓Surrounding skin condition across the entire affected region
- ✓Positioning challenges and pressure redistribution strategy
- ✓Specialized support surface documentation
- ✓Treatment plan addressing the multi-site wound
