Pressure-induced deep tissue damage of other site

This code signifies damage to the deep tissues beneath intact skin, resulting from prolonged pressure. It represents a severe form of pressure injury where the underlying muscle or subcutaneous tissue is compromised, often appearing as a purple or maroon localized area of discolored intact skin or blood-filled blister.

Apply this code when documentation clearly indicates deep tissue injury due to pressure, located at an anatomical site not specified by more granular L89 codes (e.g., not elbow, hip, heel). This diagnosis is typically made by a clinician based on visual assessment and palpation, often in patients with limited mobility.

• Ensure the documentation specifies "deep tissue injury" and not a superficial bruise or other skin lesion.
• Do not use this code for pressure ulcers with open wounds; those require specific stage codes (L89.xxx).
• Always sequence this code after any underlying condition contributing to the pressure injury, such as immobility or neurological deficits.
