Pressure ulcer of unspecified elbow, stage 4

This code signifies a full-thickness tissue loss at an unspecified elbow, where bone, tendon, or muscle is exposed. It indicates severe damage, often including undermining and tunneling, with slough or eschar potentially present.

Apply this code when documentation clearly specifies a pressure ulcer located on the elbow, but the laterality (left or right) is not specified, and the ulcer has progressed to stage 4. Supporting documentation must detail the extent of tissue damage, confirming exposure of underlying structures.

• Ensure the documentation explicitly states "stage 4" and describes the characteristic tissue loss (exposed bone/tendon/muscle).
• If laterality is specified (left or right elbow), use the more specific codes L89.014 or L89.024.
• Always sequence this code after any underlying condition causing the pressure ulcer, if applicable.
