Non-pressure chronic ulcer of neck with necrosis of bone

This code signifies a long-standing ulcer on the neck that is not caused by pressure, and has progressed to involve necrosis (tissue death) of the underlying bone. It indicates a severe, deep tissue injury with bone involvement, distinct from acute or pressure-related ulcers.

Apply this code when documentation clearly states a chronic, non-pressure ulcer located on the neck, with explicit mention of bone necrosis. Supporting documentation would include physician notes detailing the ulcer's chronicity, its non-pressure etiology, anatomical location, and imaging or surgical findings confirming bone involvement and necrosis.

• Ensure documentation specifies "chronic" and "non-pressure" to differentiate from acute or pressure ulcers.
• Verify the anatomical site is explicitly "neck" and not a generalized head/face area.
• Look for definitive statements or pathology reports confirming bone necrosis, not just exposed bone.
