Pressr ulcer of contig site of back, buttock and hip, stg 4

This code describes a severe pressure ulcer that spans across the back, buttock, and hip regions, indicating full-thickness tissue loss with exposed bone, tendon, or muscle. It signifies extensive tissue damage, often with undermining and tunneling, requiring complex medical management.

Use this code when documentation clearly indicates a stage 4 pressure ulcer involving the back, buttock, and hip simultaneously. This typically occurs in patients with prolonged immobility or compromised circulation. Supporting documentation should detail the location, severity (stage 4), and the contiguous nature of the ulcer across these three anatomical sites.

• Ensure the medical record explicitly states "stage 4" and confirms involvement of all three contiguous sites (back, buttock, and hip).
• Do not use this code if the pressure ulcers are isolated to only one or two of these sites; instead, use the specific code for the affected single site.
• Always sequence this code after any underlying condition causing the pressure ulcer (e.g., immobility, neurological conditions).
