Pressure-induced deep tissue damage of right ankle

This code signifies a severe form of pressure injury affecting the right ankle, characterized by intact skin with underlying deep tissue damage. It indicates a probable Stage 3 or 4 pressure ulcer that has not yet broken the skin surface, often appearing as a purple or maroon localized area of discolored intact skin or a blood-filled blister.

Apply this code when documentation clearly states "deep tissue injury," "deep tissue damage," or "suspected deep tissue injury" of the right ankle due to pressure. This diagnosis is typically made when there is evidence of damage to the underlying soft tissue, such as muscle or subcutaneous fat, without an open wound.

• Ensure the documentation specifies "pressure-induced" and clearly identifies the right ankle as the affected site.
• Do not use this code for open wounds; those require codes for specific pressure ulcer stages (e.g., L89.513 for stage 3).
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity.
