Pressure ulcer of right ankle, stage 3

This code signifies a full-thickness skin and tissue loss involving the subcutaneous layer, presenting as a deep crater with possible undermining or tunneling, located on the right ankle. It indicates significant tissue damage extending beyond the dermis, but without exposed bone, tendon, or muscle.

Apply this code when documentation clearly identifies a pressure ulcer on the patient's right ankle that has progressed to Stage 3. This typically involves a wound assessment describing full-thickness skin loss, visible adipose tissue, and the absence of exposed deeper structures.

• Ensure the documentation specifies "right ankle" and "stage 3" to accurately assign this code.
• Differentiate from unstageable pressure ulcers where the extent of tissue damage cannot be confirmed due to slough or eschar.
• Always sequence the pressure ulcer code first, followed by any associated codes for infection or other complications.
